- a “surface cleaning head” refers to a device configured to contact a surface for cleaning the surface by use of suction air flow, agitation, or a combination thereof.
- a surface cleaning head may be pivotably or steeringly coupled by a swivel connection to a wand for controlling the surface cleaning head and may include motorized attachments as well as fixed surface cleaning heads.
- a surface cleaning head may also be operable without a wand or handle.
- agitator refers to any element, member or structure capable of agitating a surface to facilitate movement of debris into a suction air flow in a surface cleaning head.
- transparent means capable of allowing enough light to pass through so that objects on the other side can be seen.
- a wand 102 is steeringly coupled by a swivel connection to the surface cleaning head 100 and includes a handle 104 at one end to allow the user to control the surface cleaning head 100 during use.
- the wand 102 may have a telescoping configuration to provide length adjustment.
- the handle 104 may include controls 106 (e.g., a switch and/or speed control) for controlling operation of the surface cleaning head 100.
- a surface cleaning head 100 may be provided without a wand and handle (e.g., in a robotic vacuum surface cleaning head or in a motorized attachment surface cleaning head).
- the surface cleaning head 100 includes a cleaning head housing 110, an agitator chamber 120 located in the housing 110, and a rotatable agitator 130 located in the agitator chamber 120.
- the rotatable agitator 130 rotates about a rotation axis 2 ( FIGS. 1A and 3 ) that may be generally orthogonal to the direction of travel 4 of the surface cleaning head 100.
- the agitator chamber 120 is openable to provide access to the agitator 130. Providing access to the agitator 130 within the agitator chamber 120 may allow a user to inspect and/or clean the agitator 130 without having to remove the agitator and without having to touch a dirty agitator.
- the rotatable agitator 130 may also be removable from the agitator chamber 120 for inspection, cleaning and/or replacement.
- the openable agitator chamber 120 may include a fixed agitator that is not removable, a non-rotatable or non-driven agitator or any type of cleaning member.
- the cleaning head housing 110 may generally include one or more pieces that enclose or encompass components of the surface cleaning head 100.
- the surface cleaning head 100 is used in an "all in the head" type vacuum cleaner.
- the cleaning head housing 110 encloses or encompasses an air transportation and treatment system 140 (shown schematically in FIGS. 1 and 3 ).
- the air transportation and treatment system 140 includes, for example, a suction motor 142, a cyclone including a cyclone chamber 144 and a dirt collection chamber 146 external to the cyclone chamber 144, and one or more filters 148.
- An air flow path 141 extends from a dirty air inlet 143 located in the agitator chamber 120 to a clean air outlet 145.
- the suction motor 142 causes air to be drawn into the dirty air inlet 143, through the cyclone chamber 144, and out the clean air outlet 145. As the dirt passes through the cyclone chamber 144, dirt is collected in the dirt collection chamber 146. Smaller particles may also be collected in the filter(s) 148.
- the air transportation and treatment system 140 may be similar to those used in existing or known "all in the head" type vacuum cleaners, for example, as disclosed in U.S. Patent No. 7,329,294 .
- the cleaning head housing 110 includes a front end portion 112, a rear end portion 114, laterally disposed sides 113, 115, an upper portion 116, and a bottom portion 118.
- the wand 102 is steeringly coupled to the rear end portion 114, and the agitator chamber 120 is located in the front end portion 112 and extends between a top opening 117 in the upper portion 116 and a bottom opening 119 in the bottom portion 118.
- the rotatable agitator 130 is located in the agitator chamber 120 and is configured to contact a surface to be cleaned through the bottom opening 119.
- the top opening 117 and the bottom opening 119 allow the rotatable agitator 130 to be accessed from either the top or bottom or the top and bottom simultaneously, which may help facilitate inspection or servicing of the agitator. For example, a user may clean the agitator 130 via the top opening 117 while allowing debris separated from the agitator 130 to fall out of the chamber via the bottom opening 119.
- the rotatable agitator 130 may also be removable from the agitator chamber 120, for example, through the top opening 117, as will be described in greater detail below.
- the top opening 117 of the agitator chamber 120 has a width that is greater than a width of the agitator 130 to help provide access to the entire agitator 130 and/or to allow the rotatable agitator 130 to be removed. In other embodiments, the width of the top opening 117 of the agitator chamber 120 may be shorter.
- the bottom portion 118 includes one or more bottom guards or bars 111a, 111b extending across the bottom opening 119 ( FIG. 3A ).

- the end cap 790 may further include a washer 794 (e.g., a felt washer) that contacts an end surface 736 of the agitator body 731 to keep dirt away from the bearing 792.
- the chamber 720 includes mounting rails 727a, 727b defining a recessed region 729 that receives an end portion of the end cap 790.
- the end portion of the end cap 790 may thus slide between the mounting rails 727a, 727b as shown in FIG. 22 .
- the stabilizing structures 793, 795, 797 engage corresponding structures on the mounting rails 727a, 727b and the engaging structure 728 inside of the cover 722 engages the elastomeric pad 799.
- the end cap 790 and the bushing 792 remain stationary when the agitator 730 is rotated.
- the cover 722 may engage other portions of the end cap 790 (e.g., the tab 796) to hold the end cap 790 in the chamber 720.
- the stabilizing structures 793, 795, 797 have a particular configuration designed or keyed to mate with the mounting rails 727a, 727b (see FIG.23 ) in a particular orientation such that the end cap 790 is properly positioned to be engaged by the cover 722.
- the driven end 732 is angled into the chamber 720 to engage the splined drive member 770 with the splined driven member 780 (see FIG. 16 ).
- the end cap 790 may then be used to lower the non-driven end 734 of the agitator 730 into the chamber 720 until the end cap 790 is fit between the mounting rails 727a, 727b (see FIG. 22 ).
- the external cover 722 may then be closed to cover the chamber 720 and to secure the rotatable agitator 730 within the chamber 720.
- the user may grasp the tab 796 to slide the end cap 790 out from between the mounting rails 727a, 727b and thus lift the non-driven end 734 out of the chamber 720. The user may then continue to lift the agitator 730 until the splined drive member 770 and the splined driven member 780 are disengaged. The user may then clean the agitator 730 and/or insert another type of agitator.
