Definitions

  • the present invention relates to a steam mop.
  • a floor cleaning apparatus having a floor cleaning head with a bottom for facing a floor during cleaning of the floor.
  • Such floor cleaning apparatus can be steam mops which comprises a steam permeable pad for wiping the floor.
  • EP2636353A2 discloses an example of such a steam mop.
  • the apparatus may be stored in a self-supporting manner with the bottom of the floor cleaning head still facing a floor.
  • the weight of the floor cleaning apparatus can compress the pad and the floor cleaning apparatus may susceptible to leaning or tilting from an upright orientation. This means the floor cleaning apparatus can be prone to toppling particularly if the floor cleaning apparatus is positioned on an inclined surface.
  • the apparatus includes a handle connected to the floor cleaning head for manoeuvring the apparatus.
  • a handle connected to the floor cleaning head for manoeuvring the apparatus.
  • US2004/0134025 discloses a vacuum cleaner that has a suction nozzle, a housing connected to the suction nozzle and a suction fan and motor assembly mounted to the housing.
  • a support plate is pivotally mounted to the housing and selectively holds a cleaning sheet for collecting dust and debris from a surface to be cleaned.
  • WO2013/139364 discloses an upright vacuum cleaner comprising a nozzle and a support movable between a projected state and a retracted state, wherein the support in its projected state is adapted to support the vacuum cleaner in a self standing position.
  • the support is mounted to the nozzle and projects from the nozzle in its projected state.
  • DE102011001631 discloses a floor head with legs which deploy from underneath the floor head when the handle is placed in an upright position and lifts the pad up from the floor.
  • a problem is that pad attached to the floor head has to fit between the legs and is limited in size. In order to use a larger pad, holes must be cut in the pad to allow the legs to project through but the pad can snag on the legs if the pad is fitted incorrectly.
  • a floor cleaning apparatus with a mechanism for helping to reduce the risk of toppling of the apparatus when the apparatus is not in use.
  • the mechanism would be unobtrusive when the apparatus is in use.
  • a steam mop comprising: a floor cleaning head having a top, a bottom, and a side extending between the top and the bottom, wherein the bottom is for facing a floor during cleaning of the floor; a floor cleaning pad coupled to the bottom of the floor cleaning head; and at least one stabiliser, wherein the, or each, stabiliser is connected to the floor cleaning head and is movable relative to the floor cleaning head from a stowed position to a deployed position at the side of the floor cleaning head for increasing stability of the steam mop.
  • the at least one stabiliser When the at least one stabiliser is in the deployed position the length of the floor cleaning head is increased and this helps increase the stability of the apparatus since it increases the angle over which the apparatus must rotate to move a centre of mass of the apparatus to a position at which the apparatus will topple.
  • the stabilisers prevent the floor cleaning pad from compressing and tilting the steam mop from an upright position.
  • the stabilizer Since the at least one stabilizer moves from a stowed position to a deployed position at the side of the floor cleaning head, the stabilizer will not interfere with the bottom of the cleaning head. This means that the working area of the floor cleaning head in contact with the floor which cleans the floor is bigger. In turn this means that, for example, a pad attached to the floor cleaning head can also be bigger which improves the effectiveness of the steam mop.
  • movement of the, or each, stabiliser relative to the floor cleaning head from the stowed position to the deployed position comprises movement of the, or each, stabiliser from the side of the floor cleaning head.
  • movement of the, or each, stabiliser relative to the floor cleaning head from the stowed position to the deployed position comprises movement of the, or each, stabiliser through the side of the floor cleaning head.
  • the bottom of the floor cleaning head has a surface with one or more parts that lie in a plane.
  • movement of the, or each, stabiliser relative to the floor cleaning head from the stowed position to the deployed position comprises movement of the, or each, stabiliser towards the plane.
  • the, or each, stabiliser is moveable relative to the floor cleaning head between the stowed position and the deployed position without protruding from the bottom of the floor cleaning head.
  • the steam mop comprises a handle connected to the floor cleaning head, and the handle is movable relative to the floor cleaning head from an operative position to a stored position to cause the, or each, stabiliser to move relative to the floor cleaning head from the stowed position to the deployed position.
  • the handle is movable relative to the floor cleaning head from the operative position to the stored position without causing the, or each, stabiliser to move relative to the floor cleaning head to the deployed position, when movement of the, or each, stabiliser relative to the floor cleaning head to the deployed position is obstructed.
  • the, or each, stabiliser is moveable relative to the floor cleaning head from the deployed position towards the stowed position without causing movement of the handle relative to the floor cleaning head from the stored position.
  • the steam mop comprises a mechanism for converting movement of the handle relative to the floor cleaning head from the operative position to the stored position into movement of the, or each, stabiliser relative to the floor cleaning head from the stowed position to the deployed position.
  • the mechanism comprises first and second members that are moveable relative to each other so as to absorb movement of the handle from the operative position to the stored position without moving the, or each, stabiliser from the stowed position to the deployed position.
  • the mechanism comprises a resilient apparatus that is arranged to bias the first and second members apart.
  • the steam mop comprises a lock for fixing the handle in position relative to the floor cleaning head when the handle is at the stored position.
  • the handle has a longitudinal axis. Further optionally, the longitudinal axis is closer to ninety degrees to the bottom of the floor cleaning head when the handle is at the stored position than when the handle is at the operative position.
  • the steam mop has a centre of mass that is located so that the steam mop is stable when the handle is at the stored position, the, or each, stabiliser is at the deployed position, and the bottom of the floor cleaning head is standing on a surface inclined at an angle.
  • the angle may, for example, be fifteen degrees to the horizontal, twenty degrees to the horizontal, or twenty-five degrees to the horizontal.
  • the bottom of the floor cleaning head includes one or more connectors for connecting a floor cleaning pad to the bottom of the floor cleaning head.
  • the steam mop may comprise a floor cleaning pad for releasable attachment to the bottom of the floor cleaning head via the one or more connectors.
  • the steam mop may emit steam at the bottom of the floor cleaning head.
  • the steam mop may comprise a reservoir for holding a volume of water, and a heater for heating the water sufficiently to generate the steam.
  • the heater may be electrically-powered.
  • the at least one stabiliser extends below the bottom of the floor cleaning head a distance of substantially the thickness of the floor cleaning pad. This means that the floor cleaning pad is in contact with floor when the stabilisers are in contact with the floor. However the stabilisers support the weight of the steam mop if the steam mop experiences a tilting action. This prevents the steam mop from tilting any further. By letting the floor cleaning pad engage the floor, the coefficient of friction between the steam mop and the floor is increased and the steam mop is less likely to slide down an inclined surface.

  • the bottom 121 may be planar, or flat.
  • the bottom 121 may be non-planar.
  • the bottom 121 is planar, at least because the floor cleaning pad 120 is substantially planar and compressible and the bottom 121 is planar in a plane P-P.

  • the handle interface 200 is movable relative to the floor cleaning head 100 between an operative position, as shown in Figures 1, 2 and 12 , and a stored position, as shown in Figures 9, 10 and 14 .
  • the handle interface 200 is inclined relative to the floor cleaning head 100, so that the longitudinal axis L-L forms an acute angle ⁇ with the plane P-P and the bottom 121.
  • the universal joint of the handle interface 200 enables rotation of the handle interface 200 relative to the floor cleaning head 100 about two orthogonal axes A1-A1, A2-A2.
  • a first axis A1-A1 of the axes is parallel to the width of the floor cleaning head 100 for permitting up-and-down rotational movement of the handle interface 200 relative to the floor cleaning head 100 to vary the angle ⁇ between the longitudinal axis L-L and the plane P-P.
  • a second axis A2-A2 of the axes is orthogonal to the first axis A1-A1 for permitting side-to-side rotational movement of the handle interface 200 relative to the floor cleaning head 100.

  • the longitudinal axis L-L of the handle interface 200 is closer to ninety degrees to the plane P-P and the bottom 121 of the floor cleaning head 100 than when the handle interface 200 is at the operative position. Accordingly, when the handle interface 200 is at the stored position, the handle interface 200 is more upright than when the handle interface 200 is at the operative position, so that the apparatus 1 requires less horizontal space for storage.
  • the apparatus 1 has a lock (not shown) for fixing the handle interface 200 in position relative to the floor cleaning head 100 when the handle interface 200 is at the stored position. This helps prevent the handle interface 200 from falling, if the handle interface 200 is knocked inadvertently by a passer-by during storage of the apparatus 1.
  • the apparatus when the handle interface 200 is at the stored position, the apparatus may be left to stand in a self-supporting manner with the bottom 121 of the floor cleaning head 100 still facing a floor. However, even though the apparatus 1 is more stable when in this state than when the handle interface 200 is at the operative position, the apparatus 1 still may be knocked inadvertently by a passer-by.
  • the apparatus 1 of this embodiment has first and second stabilisers 310, 320.
  • the stabilisers 310, 320 are spaced apart in the width direction of the floor cleaning head 100.
  • the stabilisers 310, 320 are connected to the floor cleaning head 100 for movement relative to the floor cleaning head 100 from a stowed position, as shown in Figures 1 to 4 and 12 , to a deployed position, as shown in Figures 9 to 11 and 14 , for increasing stability of the apparatus 1.
  • each of the stabilisers 310, 320 is movable relative to the floor cleaning head 100 from the stowed position to the deployed position at the front side 130 of the floor cleaning head 100. Therefore, the shape and structure of the bottom 121 of the floor cleaning head 100 need not be dependent on the shape and position of the stabilisers 310, 320, or the mechanism 400, described below, for controlling their movement. Accordingly, the shape of the bottom 121 is able to be made most suitable for floor cleaning and for retaining the floor cleaning pad 120.
  • movement of the stabilisers 310, 320 relative to the floor cleaning head 100 from the respective stowed positions to the respective deployed positions comprises movement of the stabiliser 310, 320 from the front side 130 of the floor cleaning head 100. Therefore, if a combination of the stabilisers 310, 320 and the floor cleaning head 100 is considered to be a body, and the body has a length in a direction parallel to the length of the floor cleaning head 100, such movement of the stabilisers 310, 320 increases the length of the body. Such increasing of the length of the body helps to increase stability of the apparatus 1, since it increases the angle over which the apparatus 1 must rotate to move a centre of mass of the apparatus 1 to a position at which the apparatus 1 will topple.
  • movement of the stabilisers 310, 320 relative to the floor cleaning head 100 from the respective stowed positions to the respective deployed positions may be in a direction parallel to the front side 130 of the floor cleaning head 100, and may not increase the length of the body.
  • movement of the stabilisers 310, 320 relative to the floor cleaning head 100 from the respective stowed positions to the respective deployed positions comprises movement of the stabilisers 310, 320 through the front side 130 of the floor cleaning head 100. More specifically, in this embodiment, when the stabilisers 310, 320 are at their respective stowed positions, at least a majority, and optionally all, of the stabilisers 310, 320 is located at an interior of the floor cleaning head 100. Therefore, the stabilisers 310, 320 are unobtrusive when at their respective stowed positions.
  • Movement of the stabilisers 310, 320 to their respective deployed positions results in the stabilisers 310, 320 passing through the front side 130 of the floor cleaning head 100 from the interior of the floor cleaning head 100 to the exterior of the floor cleaning head 100.
  • movement of the stabilisers 310, 320 relative to the floor cleaning head 100 from the respective stowed positions to the respective deployed positions comprises movement of the stabilisers 310, 320 between two positions at the exterior of the floor cleaning head 100, and the stabilisers 310, 320 may never pass through a side 130, 140, 150, 160 of the floor cleaning head 100.
  • the stabilisers 310, 320 are movable relative to the floor cleaning head 100 between the stowed position and the deployed position without protruding from the bottom 121 of the floor cleaning head 100. Therefore, movement of the stabilisers 310, 320 relative to the floor cleaning head 100 need not cause the apparatus 1 to be lifted from the floor, when the apparatus 1 is standing with the bottom 121 facing the floor, which otherwise could unbalance the apparatus 1 and cause it to topple. Moreover, this avoids the risk of deployment of the stabilisers 310, 320 being hindered or prevented by a floor cleaning pad 120 connected to the bottom 121, in instances when a floor cleaning pad is so connected to the bottom 121.
  • Movement of the stabilisers 310, 320 from the side and not the bottom means that the stabilisers do not have to project through the floor cleaning pad 120 and the floor cleaning pad 120 is not required to have holes therein to receive the stabilisers 310, 320.
  • the floor cleaning pad 120 can at least cover the entire surface of the bottom 121 and in some embodiments the floor cleaning pad 120 can have an area greater than the area of the bottom 121.
  • movement of the stabilisers 310, 320 from their respective stowed positions to their respective deployed positions comprises movement of the stabilisers towards the plane P-P described above. Therefore, during deployment of the stabilisers 310, 320, the stabilisers 310, 320 are moved in the direction of the floor, when the apparatus 1 is standing with the bottom 121 facing the floor. Movement of the stabilisers 310, 320 towards the plane P-P helps to increase stability of the apparatus 1, since it increases the angle over which the apparatus 1 must rotate to move the centre of mass of the apparatus 1 to a position at which the apparatus 1 will topple. Most floors are substantially flat.
  • the stabilisers 310, 320 would come into contact with the floor. This helps to reduce the risk of toppling of the apparatus 1 when the apparatus is not in use.
  • the stabilisers 310, 320 when the stabilisers 310, 320 are at their respective deployed positions, part of each of the stabiliser 310, 320 is in the plane P-P. Accordingly, when deployed, the stabilisers 310, 320 act to increase the area over which the apparatus 1 contacts a flat floor, when the apparatus 1 is standing with the bottom 121 facing the floor, which further helps to reduce the risk of toppling of the apparatus 1 when the apparatus is not in use.
  • the stabilisers 310, 320 are configured to move in a direction which is substantially perpendicular to the plane P-P. This can be seen from comparing Figure 7 with Figure 9 .
  • the stabilisers 310, 320 move in a vertical direction at least the thickness of the floor cleaning pad 120 below the bottom 121. If the stabilisers 310,320 only extended to a position in line with the bottom 121, the floor cleaning pad is compressible and can cause tilting of floor cleaning apparatus 1 if the compression of the floor cleaning pad 120 is not uniform (e.g. on one side only). This means that the stabilisers prevent the floor cleaning pad 120 from compressing under the weight of the floor cleaning apparatus 1. In this way the floor cleaning pad 120 cannot compress only on one side which can exaggerate the tilting of the floor cleaning apparatus 1.
  • the centre of mass of the apparatus 1 is located so that the apparatus 1 is stable when the following three conditions are met simultaneously:
  • the centre of mass is modified such that the floor cleaning apparatus 1 does not topple if it receives a knock when all three conditions (a) (b) and (c) are met.
  • the centre of mass of the apparatus 1 is located so that the apparatus 1 is stable when the first two conditions are true and the third condition is that the bottom 121 of the floor cleaning head 100 is standing on a surface inclined at more than fifteen degrees to the horizontal, such as twenty degrees to the horizontal or twenty-five degrees to the horizontal.
  • the apparatus 1 has a mechanism 400 that is for converting movement of the handle interface 200 relative to the floor cleaning head 100 from the operative position to the stored position into movement of the stabilisers 310, 320 relative to the floor cleaning head 100 from their respective stowed positions to their respective deployed position.
  • the mechanism 400 of this embodiment will now be described in more detail with reference to Figure 11 .
  • the mechanism 400 comprises a first member 410, a second member 420, a resilient apparatus 430, a first arm 440, a second arm 450, and a torsion spring 460.
  • the first member 410 is slidably connected to the second member 420 via the resilient apparatus 430 for movement in a direction parallel to the length of the floor cleaning head 100.
  • a front face 411 of the first member 410 is for abutting a lower end of the handle interface 200 on sufficient rotation of the handle interface 200 relative to the floor cleaning head 100 from the operative position, as will be described below.
  • the second member 420 is slidably connected to the floor cleaning head 100, and more specifically to the chassis 101, for movement in a direction parallel to the length of the floor cleaning head 100.
  • Respective first ends 441, 451 of the first and second arms 440, 450 are rotatably connected to the second frame 420, and respective second ends 442, 452 of the first and second arms 440, 450 are rotatably connected to the respective first and second stabilisers 310, 320.
  • the first and second arms 440, 450 are rotatably connected to the floor cleaning head 100, and more specifically to the chassis 101, at respective pivots 445, 455.

  • the stabilisers 310, 320 are located in respective channels 171, 172 of the floor cleaning head 100.
  • the channels 171, 172 are for constraining the stabilisers 310, 320 to motion relative to the floor cleaning head 100 between their stowed and deployed positions.
  • the first stabiliser 310 has first and second followers 311, 312, which are respectively located in first and second cam tracks 181, 182 of the floor cleaning head 100.
  • the second stabiliser 320 has first and second followers, which are respectively located in third and fourth cam tracks of the floor cleaning head 100.
  • Each of the first to fourth cam tracks 181, 182 has a front-most end closest to the front side 130 of the floor cleaning head 100, and a rear-most end closest to the rear side 140 of the floor cleaning head 100.
  • the first and third cam tracks 181 are linear and parallel to the plane P-P
  • each of the second and fourth cam tracks 182 has first and second linear portions 182a, 182c parallel to the plane P-P that are joined by a mid-portion 182b that is inclined to the plane P-P.
  • the followers 311, 312 and cam tracks 181, 182 are for guiding the motion of the stabilisers 310, 320 relative to the floor cleaning head 100, so as to rotate the stabilisers 310, 320 relative to the floor cleaning head 100 as the stabilisers 310, 320 are moved between the stowed and deployed positions, as will be described below.
  • Figures 1, 2 and 12 show the handle interface 200 at its operative position relative to the floor cleaning head 100, and the stabilisers 310, 320 at their respective stowed positions. Accordingly, the followers 311, 312 of the first and second stabilisers 310, 320 are at the rear-most end of the cam tracks 181, 182 of the floor cleaning head 100.
  • the handle interface 200 is rotatable relative to the floor cleaning head 100 about the first axis A1-A1 to vary the angle ⁇ between the longitudinal axis L-L and the plane P-P.
  • the handle interface 200 is movable to a certain extent in this manner without causing movement of the stabilisers 310, 320 relative to the floor cleaning head 100.
  • the resilient apparatus 430 has a spring constant suitable to transmit this rearward movement of the first member 410 to the second member 420 without deforming the resilient apparatus 430, so that the second member 420 also is urged towards the rear side 140 of the floor cleaning head 100.
  • the stabilisers 310, 320 move substantially linearly from the position shown in Figure 4 to the position shown in Figure 6 in a direction substantially parallel to the plane P-P.
  • the handle interface 200 continues to cause the first and second members 410, 420 to move towards the rear side 140 of the floor cleaning head 100.
  • the stabilisers 310, 320 are rotated as they move from the position shown in Figures 5 and 6 to the position shown in Figures 7 and 8 , so that distal ends of the respective stabilisers 310, 320 are moved towards the plane P-P.
  • the handle interface 200 continues to cause the first and second members 410, 420 to move towards the rear side 140 of the floor cleaning head 100.
  • the first followers 311 of the stabilisers 310, 320 continue along the respective linear first and third cam tracks 181 to reach the front-most ends of the respective first and third cam tracks 181, and the second followers 312 of the stabilisers 310, 320 move along the respective second linear portions 182c of the second and fourth cam tracks 182 to reach the front-most ends of the respective second and fourth cam tracks 182.
  • the second followers 312 When the stabilisers 310, 320 are at their respective deployed positions shown in Figures 9 to 11 and 14 , the second followers 312 would not pass back down the inclined mid-portions 182b of the second and fourth cam tracks 182 if a turning moment is applied to the stabilisers 310, 320 to encourage the second followers 312 towards the plane P-P, since the second linear portions 182c of the second and fourth cam tracks 182 are parallel to the plane P-P.
  • the lock (not shown) fixes the handle interface 200 in position relative to the floor cleaning head 100.
  • the at least one stabiliser 310, 320 extends below the bottom 121 of the floor cleaning head a distance of substantially the thickness of the floor cleaning pad 120. In this way the floor cleaning pad 120 is still in contact with the floor in the stowed position, but the stabilisers 310, 320 prevent the floor cleaning pad 120 from compressing. This means that the floor pad 120 itself can partially support the weight of the floor cleaning apparatus 1 without compressing in a nonuniform manner. Furthermore by having the floor cleaning pad 120 in contact with the floor, the pad 120 itself increases the coefficient of friction between floor and the floor cleaning apparatus 1 and this prevents the floor cleaning apparatus 1 from sliding, particularly on an incline.
  • the stabilisers 310, 320 can extend a distance greater than the thickness of the pad 120. In this case the floor cleaning pad 120 is not in contact with the floor when in the stowed position. This can be useful to prevent a dirty floor cleaning pad touching a clean floor when the floor cleaning apparatus is in the stowed position.
  • the lock (not shown) is unlocked and the handle interface 200 is moved from its stored position, shown in Figures 9 to 11 and 14 , towards its operative position, shown in Figures 1, 2 and 12 .
  • unlocking of the lock is effected through user actuation of a foot pedal 190 at the rear side 140 of the floor cleaning head 100.
  • the manner in which actuation of the foot pedal 190 causes unlocking of the lock will not be described in the interests of conciseness, but a suitable mechanism would be known to the person skilled in the art in light of this disclosure.
  • the lower end of the handle interface 200 moves in a direction away from the rear side 140 of the floor cleaning head 100 and away from the front face 411 of the first member 410.
  • the torsion spring 460 acts to rotate the first arm 440 in an anticlockwise direction, as Figure 11 is drawn, and thus to bias the first member 410 away from the rear side 140 of the floor cleaning head 100, so as to bias the stabilisers 310, 320 to their respective stowed positions.
  • movement of the handle interface 200 from its stored position to its operative position causes the stabilisers 310, 320 to move relative to the floor cleaning head 100 from their respective deployed positions to their respective stowed positions.
  • a user may choose to move the handle interface 200 relative to the floor cleaning head 100 from its operative position towards its stored position when movement to the deployed position of one or both of the stabilisers 310, 320 is obstructed.
  • the apparatus 1 of this embodiment may be located with the front side 130 of the floor cleaning head 100 abutting a wall.
  • the handle interface 200 of this embodiment is movable relative to the floor cleaning head 100 from the operative position to the stored position without causing the stabilisers 310, 320 to move relative to the floor cleaning head 100 to the respective deployed positions.
  • movement of the handle interface 200 relative to the floor cleaning head 100 towards the stored position causes the stabilisers 310, 320 to move towards their respective deployed positions as described above, until they abut the obstruction. Thereafter, further movement of the handle interface 200 relative to the floor cleaning head 100 towards the stored position by application of a force sufficient to overcome the biasing force of the resilient apparatus 430 causes relative movement of the first and second members 410, 420. In this embodiment, this relative movement is effected through compression of the two coil springs 431, 432, so as to deform the resilient apparatus 430. In embodiments in which the resilient apparatus 430 takes a different form to that of this embodiment, deformation of the resilient apparatus 430 may be effected in some other manner.
  • the first and second members 410, 420 are moveable relative to each other sufficiently to absorb movement of the handle interface 200 from its operative position to its stored position without moving the stabilisers 310, 320 from their respective stowed positions to their respective deployed positions. This helps to avoid damage to the stabilisers 310, 320 or to the mechanism 400 in the scenario described above, in which movement of the stabilisers 310, 320 is obstructed.
  • this deformability of the resilient apparatus 430 permits the stabilisers 310, 320 to be moved relative to the floor cleaning head 100 from their respective deployed positions to their respective stowed positions without causing movement of the handle interface 200 relative to the floor cleaning head 100 from its stored position.
  • the apparatus 1 when the apparatus 1 is arranged with the handle interface 200 at its stored position and the stabilisers 310, 320 at their respective deployed positions, if the stabilisers 310, 320 are moved in a direction towards their respective stowed positions, such as by a user pushing the stabilisers 310, 320 against a wall by application of a force sufficient to overcome the biasing force of the resilient apparatus 430, the first and second members 410, 420 are moved relative to each other to deform the resilient apparatus 430. Again, this helps to avoid damage to the stabilisers 310, 320 or to the mechanism 400.
  • the resilient apparatus 430 thus may be considered an apparatus for controlled deformation, that is arranged to absorb energy from forces sufficient to overcome the biasing force of the resilient apparatus 430 and applied to the stabilisers 310, 320 or to the handle interface 200 when movement of the other is obstructed or prevented, to help avoid such forces damaging the stabilisers 310, 320 or the mechanism 400.
  • This embodiment of the present invention therefore provides a mechanism for helping to reduce the risk of toppling of the apparatus 1 when the apparatus 1 is not in use.
  • the mechanism is unobtrusive when the apparatus 1 is in use.
  • stabilisers such as spaced apart stabilisers
  • at least one additional rear stabiliser may be provided on the floor cleaning head 100. The at least one additional rear stabiliser may be actuated and project rearwardly, in an opposite direction to the first and second stabilisers 310, 320.
  • a mechanical linkage and camming track may be provided between the handle interface 200 and the at least one rear stabiliser.
  • the at leat one rear stabiliser may be configured to move in a rearward direction when the handle interface 200 is moved into a deployed position. This would mean that the stabilisers move forwards and backwards when the floor cleaning apparatus 1 is put in the stowed position.
  • the apparatus 1 may have only one stabiliser.
  • the stabiliser may be movable relative to the floor cleaning head 100 from the stowed position to the deployed position at the front, or rear, or left, or right side 130, 140, 150, 160 of the floor cleaning head 100.
