The present disclosure provides a dry-wet separation cleaning floor brush. The dry-wet separation cleaning floor brush includes a housing, a stiff roller brush and a soft roller brush, wherein the housing is provided with a partition plate dividing the inner part of the housing into a first storage chamber and a second storage chamber which are disconnected to each other, wherein the stiff roller brush is partially contained in the first storage chamber and is movably connected to the housing, and the stiff roller brush partially protrudes the housing; and the soft roller brush is partially contained in the second storage chamber and movably connected to the housing, and the soft roller brush partially protrudes the housing.

Provided are a vacuum head, a collection bin, a cleaning tray, a filter assembly, and a cleaning apparatus. The cleaning apparatus includes: a housing, a rolling brush, and a cleaning assembly, where the cleaning assembly includes a cleaning medium inlet and a plurality of cleaning medium spray orifices; the plurality of cleaning medium spray orifices face the rolling brush, and lengths of flow channels from various cleaning medium spray orifices to the cleaning medium inlet are equal. According to the present disclosure, a cleaning medium may be sprayed to a rolling brush surface uniformly, so that the rolling brush may be cleaned completely, thereby improving the cleaning efficiency and the cleanliness of the rolling brush.

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 cleaning machine may include: a first brush including a first brush shaft and a first brush body held by the first brush shaft; a second brush including a second brush shaft and a second brush body held on the second brush shaft; a first brush attaching member having a first shape, wherein one end of the first brush shaft is detachably attached to the first brush attaching member; and a second brush attaching member having a second shape, wherein one end of the second brush shaft is detachably attached to the second brush attaching member. The one end of the first brush shaft may have a first corresponding shape that corresponds to the first shape. The one end of the second brush shaft may have a second corresponding shape that corresponds to the second shape. Other end of the first brush shaft may have the second corresponding shape.

A roller brush assembly comprises a roller and a brush set on the roller. The roller contains an interior cavity constituted by at least two barrel bodies. Each portion of the barrel body edge is serrated shaped, and the adjacent serrated-shaped portions of the barrel both form a blade slot for positioning the serrated-shaped blade, and the blade edge corresponds to the teeth on the serrated shaped edge. A driver unit is installed in the interior cavity to make the blade move along the roller axially to cut the wrapped in the tooth groove automatically when the roller brush is turned on and off.

A robot cleaner enables a wet cleaning, has a replaceable cleaning unit, and ensures a sufficient friction force for doing a wet cleaning of a floor. The robot cleaner includes a frame including a wheel for driving, a replaceable cleaning unit formed at a lower part of the frame to clean a bottom surface and disposed in front of the wheel, a tank disposed at an upper part of the wheel and configured to supply fluid to the cleaning unit, a pump configured to pump the fluid contained in the tank such that the fluid contained in the tank is supplied to the cleaning unit, a hose configured to extend to the pump and the upper part of the cleaning unit and through which the fluid pumped by the pump flows, and a bumper formed on a side of the frame.
