A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the upright handle assembly and adapted for movement across a surface to be cleaned. The surface cleaning apparatus is further provided with a fluid delivery system comprising a fluid dispenser configured to dispense fluid to a brushroll and at least one fluid delivery channel forming a portion of a fluid delivery pathway. The fluid delivery channel can extend adjacent to a portion of the suction nozzle assembly. An interference wiper interfaces with a portion of the brushroll to remove excess liquid from the brushroll.

An autonomous mobile apparatus such that damage to a camera thereof can be avoided. The autonomous mobile apparatus includes: a main body case; a running gear for moving the main body case when placed on the floor; a driving force source for driving the running gear; a robot controller for controlling the driving force source so that the main body case autonomously moves on the floor; a bumper disposed on the front side of the main body case; and a camera unit disposed on the rear side of a side surface of the main body case and images the area behind the main body case.

A cleaning apparatus includes a combing unit including a series of spaced protrusions or teeth extending into a cleaning roller for preventing build up and removing debris (such as hair, string, and the like). The protrusions extend along a substantial portion of the cleaning roller and extend partially into the cleaning roller to intercept the debris as it passes around the roller. The protrusions have angled leading edges that are not aligned with a rotation center of the cleaning roller and are directed into or against a direction of rotation of the cleaning roller. The combing unit and protrusions have a shape and configuration designed to facilitate debris removal from the cleaning roller with minimal impact on the operation of the cleaning apparatus. The cleaning apparatus may include a surface cleaning head of an upright vacuum cleaner or sweeper or a robotic vacuum cleaner.

A vacuum accessory tool is provided. The vacuum accessory tool includes a body, a turbine, a generator, and a light source. The body defines a suction inlet, a fluid outlet, and a fluid flow path extending from the suction inlet to the fluid outlet. The turbine is rotatably mounted to the body in fluid communication with the fluid flow path to be rotated by fluid passing through the fluid flow path. The generator is coupled to the turbine such that rotation of the turbine rotates the shaft to generate power. The light source is electrically coupled to the generator and configured to receive the power generated by the generator to power the light source by the fluid passing through the fluid flow path.

A surface cleaning apparatus includes a surface cleaning head having a dirty air inlet and an upper section mount moveably coupled to the surface cleaning head. An upper portion is mounted to the upper section mount. The upper section comprises a wand. A portable surface cleaning unit is removably mounted to the upper portion. An air flow path extends from the dirty air inlet to a clean air outlet and includes an upstream portion comprising the wand and a flexible air flow conduit downstream of the wand. Each of the wand and the portable cleaning unit can be separately removable from the upper section mount.
