Abstract: A surface cleaning head includes a removable rotatable driven agitator, such as a brush roll, which is driven by a drive mechanism that axially engages the driven end. The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. Different removable agitators with different characteristics may be used interchangeably in the surface cleaning head. The surface cleaning head may also include one or more transparent regions (e.g., on the openable cover) to allow visual inspection of the agitator during use.

Abstract: A wand includes a hinge configured to pivotally connect first and second wand segments in an extended configuration and a storage configuration. A first locking mechanism locks the wand in extended configuration. A second locking mechanism includes a rod, a sliding lever, a plunger, and a plunger cavity. The plunger is configured to be received in the plunger cavity to lock the wand in the storage configuration. When in the extended configuration, depressing a single actuator pivots the locking arm, causes the hook/pawl to be removed from the locking cavity, and unlocks the wand. When in the storage configuration, depressing the single actuator causes the rod to move in a first direction, causes the sliding rod to move a second direction, and urges the plunger out of the plunger cavity.

Abstract: An example of a vacuum pod may include a handle, a vacuum pod body, a dust cup removably coupled to the vacuum pod body, and a fluid conduit fluidly coupled to the dust cup. The fluid conduit may include a flexible hose configured to transition between an expanded and a retracted position and a coupling configured to be removably coupled to the vacuum pod body. A first end of the flexible hose may be coupled to the vacuum pod body and a second end of the flexible hose may be coupled to the coupling. When the coupling is coupled to the vacuum pod body, the flexible hose may be in the retracted position.

Abstract: An example of a surface cleaning head may include a main body, a neck pivotally coupled to the main body, a stabilizer, and a linkage pivotally coupled to the main body and the stabilizer. The linkage may be configured to cause the stabilizer to transition between an extended position and a retracted position in response to a pivotal movement of the neck.

Abstract: A surface cleaning head may be configured to receive a removable rotatable driven agitator, such as a brush roll, or a non-driven agitator. Either of these agitators may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The non-driven agitator may include an agitator body including a bottom portion supporting one or more cleaning pads. The non-driven agitator body may also define one or more air inlets, an air outlet and an air passageway extending therebetween to facilitate air passage through the surface cleaning head. Different removable agitators with different characteristics may be used interchangeably in the surface cleaning head.
