The pipe connected to the housing, the pipe including a water inlet and a water outlet, the water inlet being located on an upper side of the housing, the water outlet being located on a lower side of the housing, and the water inlet being configured for connecting to a high pressure water source. The nozzle connected to the water outlet. The wheel assemblies rotatably connected to the housing by the connecting assembly. The locking means connected to the housing and configured for locking the wheel assembly.

The present disclosure relates to a robot cleaner including a body having a space for accommodating a battery, a water container, and a motor therein, a first rotary plate having a lower portion to which a first mop is coupled, and a second rotary plate having a lower portion to which a second mop is coupled, in which the body includes a bottom surface disposed to be directed toward a floor, and mop support portions disposed on the bottom surface, protruding downward, and configured to be in contact with the first mop and the second mop, and the mops are bent by being brought into contact with the mop support portions, thereby increasing a frictional force between the floor and the mops.

A floor cleaner including a including a base, an upright portion, and a recovery tank. The recovery tank includes a baffle configured to separate liquid and air from a liquid-laden stream entering the recovery tank.

A floor cleaner including a including a base, an upright portion, and a recovery tank. The recovery tank includes a baffle configured to separate liquid and air from a liquid-laden stream entering the recovery tank.

A floor cleaning machine is provided, comprising a suction unit device, a suction bar which is operatively connectable, or operatively connected, to the suction unit device for fluid communication therewith, a holder which releasably holds the suction bar, a fixing device for releasably fixing the suction bar at the holder, and an overload protection device which is associated with the suction bar, wherein the overload protection device comprises at least one rotational bearing by way of which the suction bar is rotatable at the holder relative to the holder when an overload situation occurs.

A portable surface treatment tool is provided, which is configured for attachment to a suction controller. The portable surface treatment tool is configured for use with vertical, overhead, inclined and horizontal surfaces and includes a head and a handle coupled to the head. The head includes: a rotatable surface treatment unit configured to engage a surface to be treated; a motor configured to drive the rotatable surface treatment unit; and a shroud substantially encasing at least a portion of the rotatable surface treatment unit, the shroud defining a suction region proximal the rotatable surface treatment unit. The suction region is configured to suck fluid from a surface to be treated. The shroud defines a suction connection formation configured to be coupled to a source of suction supplied by a suction controller, the suction connection formation being in fluid communication with the suction region to remove fluid from a surface to be treated.

A cleaning device including a covering hood having a lower surface facing a surface to be cleaned and an inlet on an upper surface thereof, through which contaminants are sucked; an air knife provided on a circumference of the covering hood and having an outlet for spraying high pressure air to the surface to be cleaned; a sweeper installed inside the covering hood and rotated by a driving motor to guide foreign objects swept away from the surface to be cleaned and contaminants floated by the high pressure air injection of the air knife to the inlet; a rotary member including a shaft passing through a circumferential surface of the covering hood and the air knife, and a rotary knob coupled to one end of the shaft to rotate the air knife to adjust an air spray angle.

A wet-cleaning appliance, in particular a wet mop, has a cleaning roller, which is mounted in a rotatable manner about a roller axis, and having a roller cover, which encloses the cleaning roller in the circumferential direction, at least in part, and has at least one movable covering element for optionally closing and/or releasing an opening region of the roller cover. In order to prevent residual liquid contained in the roller cover from dripping from the wet-cleaning appliance when the roller cover is opened, the movable covering element has a collecting unit, in particular a collecting container, which has a storage volume for collecting liquid that remains in the roller cover.

A floor washing-drying machine includes a framework, which can move on the floor and supports, in a lower region, a floor washing assembly having at least one rotating brush and at least one nozzle for dispensing a washing liquid. A floor drying assembly is arranged at the rear of the washing assembly, which comprises includes a rear floor wiper, which extends substantially transversely to the advancement direction of the machine, and a suction device which is connected to a tank for recovering the dirty liquid. The machine further includes at least one pair of lateral floor wipers, which are arranged on mutually opposite sides with respect to the vertical central plane of the framework and extend substantially along at least one portion of the longitudinal extension of the framework; each one of the lateral floor wipers includes respectively at least three vertical drying blades.
