A cleaning apparatus for a cleaner robot is provided and includes a main body. An accommodation cavity is formed inside the main body. The cleaning apparatus further includes a water spraying device and a sweeping roller, the water spraying device is disposed in the accommodation cavity and detachably connected with the accommodation cavity, and the sweeping roller is disposed in the accommodation cavity and detachably connected with the accommodation cavity. A water squeezing rod is arranged between the sweeping roller and the accommodation cavity. The main body is further disposed with a sewage recovery device detachably connected therewith. The sewage recovery device includes a sewage sink disposed at an inner side of the sweeping roller, and the sewage sink abuts against the inner side. The main body is further disposed with a driving device for driving the sweeping roller to rotate.

The present disclosure provides a surface cleaning apparatus that includes a housing including a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft surfaces, and for different cleaning modes, including wet cleaning, dry vacuum cleaning, and self-cleaning. Methods for self-cleaning a surface cleaning apparatus are also provided.

A vacuum cleaner includes a base and a brushroll positioned within the base. The base has a suction opening and is configured to move along a surface to be cleaned. The brushroll is rotatable relative to the base about an axis, and the brushroll includes a first end, a second end, an inflection point located between the ends, and a material that protrudes radially away from the brushroll. The material extends between the first end and the second end and wraps around the brushroll with a pitch. The material wraps in a first direction between the first end and the inflection point and wraps in a second direction between the inflection point and the second end.

The present disclosure relates generally to an apparatus for cleaning or otherwise treating a floor or ground surface. Devices provided herein include various features to enhance the efficiency and efficacy of cleaning operations. Such devices includes, but are not limited to, bearing protector devices, cord and cable management devices, and ergonomic features useful with ride-on floor treating machines.

A rotor assembly is provided and includes a rotor, tongs and an actuation system. The rotor includes a shaft defining a rotational axis about which the rotor is rotatable and rotor elements supported on the shaft to define grooves. The tongs are disposed in the grooves to occupy and move between first and second positions. At the first positions, the tongs are retracted from the grooves. At the second positions, the tongs are engaged in the grooves to disentangle fibers from the rotor. The actuation system is configured to bias the tongs toward the first positions and is actuatable to drive the tongs into the second positions.

A surface cleaning apparatus includes an upright body and a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft surfaces, and for different cleaning modes, including wet cleaning, dry vacuum cleaning, and self-cleaning. Methods for self-cleaning a surface cleaning apparatus are also provided.

A wet cleaning device, in particular a wet wiping device, has a cleaning roller which is rotatable about a roller axis and has a cleaning lining. In order to create a wet cleaning device in which the regeneration effect is optimized, in particular while using a minimum of liquid, the wet cleaning device has a decelerating element to assist the removal of liquid and/or of dirt from the cleaning roller, which element has an impact edge directed radially outwards with respect to the roller axis and is arranged between fibers of the cleaning lining during a regeneration operation in such a way that the free ends of the mechanically unloaded fibers project outwards in the radial direction beyond the impact edge.
