Definitions

• the invention relates to an escalator and moving walk cleaning device according to the preamble of claim 1.
• Moving walks are often used at airports to transport passengers over longer distances in the plane or slightly increasing from one floor to the next.
• the escalators as well as the moving walks from different manufacturers are characterized by different web and groove widths, whereby the dirt naturally accumulates in the grooves of the ribbed moving floor panels.
• the groove depths are also different sizes for different manufacturers.
• a cleaning device for escalators and moving walks has already been proposed, which is moved in particular in the case of an escalator to the start or end area, at which the moving escalator elements still run out horizontally.
• the device remains stationary in this situation, so it is still supported on the floor in front of the actual escalator, whereby the escalator moving under it is cleaned by means of the cleaning and processing head.
• adapter strips must be replaced that have protruding fingers that are adapted to the groove and web width or groove depth of the escalator elements of the manufacturer in question. Because during the cleaning process, the engagement of such elements in the grooves of the escalator elements must ensure that a corresponding negative pressure is generated during suction in order to actually be able to suck the dirt out of the grooves and grooves.
• the object of the present invention is to provide an improved escalator and moving walkway cleaning device.
• the cleaning device according to the invention has numerous surprising features that are completely new compared to the prior art, which on their own, but above all in combination, result in significant improvements during the cleaning process.
• the cleaning device according to the invention is distinguished on the one hand by the fact that it has a support foot which is offset from the cleaning head, so that the cleaning head of the cleaning device can be raised or lowered by applying pressure to a handle via this support foot.
• the cleaning device according to the invention is designed in such a way that it can "walk” from step to step on an escalator.
• the cleaning device is also distinguished by a special strip brush, which makes it possible to generate a sealing function on the escalator or moving walk elements, regardless of the manufacturer-specific profile, in order to maintain a defined suction flow.

• the cleaning head can be rotated through 180 ', as a result of which the suction strip and the strip brushes according to the invention provided come to rest on the other side in relation to the rotating cleaning elements. This enables an optimal suction and cleaning effect to be achieved.
• the suction nozzle and cover of the rotating roller brush are designed in such a way that, regardless of step heights or length of the tread surface or the essentially vertically extending end face of a step, they always adapt exactly.
• the cleaning device is a hand-held device for cleaning escalators and moving walks.
• a so-called tiller pushes itself over a support with rollers on the treads of the objects to be cleaned in order to enable a rocking movement.

• the direction of rotation of the roller brushes is selected in such a way that the loosened dirt is transported away from the sensitive open edge (which results in escalators between the individual movable steps).
• the dirt is sucked through a hose into a "steam suction cleaner" via these nozzles.
• the unit mounted on a central tube can be swiveled by 180 "so that it is ready for use for the" end faces “of the stairs.

• the roller brushes are placed close to the side walls, switched on and cleaning is carried out by pulling the unit back and forth.
• rollers In addition to the small rollers attached in the longitudinal direction of the machine, there are also rollers for lateral movement. By tilting the cleaning device backwards, they come into engagement and the unit can thus be moved laterally to treat the surfaces that have not yet been cleaned.
• the cleaning device is now pivoted far down on the steering unit and pushed forward in order to advance to the next level and continue cleaning. Climbing will be limited after approx. 12-15 steps, as the hose and cable lengths determine the radius of action.
• the entire cleaning head is now swiveled by 180 'with a lever that can be reached from the steering unit, in order to then "descend" step by step.
