An automatic cleaning machines comprises a high-speed reciprocating cleaning means making a cleaning cloth reciprocatingly wipe a floor at high speed and a vacuum device sucking the dust in front of the cleaning cloth.

A cleaning appliance includes: a main body with a bottom side, the main body being assigned on the bottom side, which faces toward a floor to be cleaned, at least one cleaning body, the at least one cleaning body being mounted on the main body so as to be rotatable about an axis of rotation, the axis of rotation of the cleaning body being oriented perpendicularly to the bottom side. The at least one cleaning body is mounted in the main body such that, during cleaning, the axis of rotation is movable relative to the bottom side along a movement path which is oriented perpendicularly to the axis of rotation.

A hand-guided floor treatment device includes a bottom part, which includes at least one tool which is rotatable on a floor by a drive, as well as a guide part which includes at least one handle and is connected to the bottom part by an articulated arrangement which is developed in such a manner that the guide part, proceeding from a perpendicular, is pivotable in relation to the perpendicular in angular positions rotating in all directions and is operatively connected to the bottom part so as to transmit torque in an angularly limited manner in each angular position in relation to the perpendicular. The at least one rotatable tool is arranged in such a manner on the bottom part that when the floor treatment device is operating the at least one rotatable tool exerts permanent linear propulsion on the bottom part.

A nozzle for a cleaner has a nozzle housing, which has a nozzle base and a drain hole for discharging water from the nozzle housing. The nozzle also has a rotary cleaning unit disposed below the nozzle housing. The rotary cleaning unit has a rotation plate that can be attached to a mop. The nozzle has a driving unit that includes a driving motor for driving the rotary cleaning unit The nozzle also has a control board for controlling the drive motor. In addition, the nozzle has a water tank detachably mounted on an upper side of the nozzle housing. The water tank stores water and supplies the water to the rotary cleaning unit

A surface cleaning apparatus includes include at least a recovery system for removing the spent cleaning fluid and debris from the surface to be cleaned and storing the spent cleaning fluid and debris. The recovery system is provided with a recovery tank having a removably strainer that is configured to strain large debris and hair out of the recovery tank prior to emptying the recovery tank.

An apparatus for cleaning a floor includes a housing, wheels by which the apparatus is adapted to move; a motive device for moving the apparatus, a steering mechanism, and a cleaning assembly including a cleaning unit and an offset mechanism adapted to move the cleaning unit to or from an offset position projecting beyond one lateral side of the apparatus. In another embodiment, an apparatus for cleaning a floor includes a housing, wheels by which the apparatus is adapted to move, a motive device for moving the apparatus, a steering mechanism, and a cleaning assembly including a cleaning unit and a swing mechanism indirectly linking the cleaning unit to the steering mechanism such that when the apparatus is in an operative mode, the cleaning unit reorients its position in synchronization with the path of travel of the apparatus. Optionally, a lifting device may raise and lower the cleaning assembly.

The present invention relates generally to an apparatus for cleaning or otherwise treating a floored surface that includes a platform adapted to support the weight of an operator. In addition, one embodiment of the present invention is capable of generally performing 360° turns to facilitate the treatment of difficult to access portions of the floored surface.

A multifunctional mopping machine includes a handle, a body and a main machine. The body includes a mounting base, and a housing provided with a cleaning assembly; the body is detachably connected to the mounting base; the main machine includes a negative pressure assembly and a power supply assembly; the power supply assembly, the negative pressure assembly and the cleaning assembly form a cleaning mechanism; and a water tank for supplying water to the cleaning assembly, and a sodium hypochlorite electrolysis generator are arranged on the mounting base. An ultraviolet sterilizing lamp facing the ground to be cleaned is arranged on the housing. A tail end of a dust collecting hose communicates with a negative pressure end of the main machine, and collects both dirty water and dust on the floor, so as to ensure no stain left on the floor, satisfying present floor washing requirements.

A system and method can be provided for detecting the status of one or more components and/or systems of, for example, a manual, semi-autonomous, or fully autonomous cleaning device or the like. Embodiments described herein relate to a system that provides semi-autonomous cleaning of surfaces by a semi-autonomous cleaning device. The system provides for improved reliable obstacle detection and avoidance, improved sensing, improved design, improved failure detection, advanced diagnostics and expandability capabilities.

A cleaner includes a nozzle assembly, a cleaner body in communication with the nozzle assembly, and a damp cloth-based wiping unit coupled to the nozzle assembly. The damp cloth-based wiping unit includes a water tank. The water tank includes a storage space defined therein for storing water, an air hole defined in a top face of the water tank for receiving external air, a discharging port formed on a bottom face of the water tank for discharging the water from the storage space, and a deformable member configured to be depressed inwardly into the storage space. A damp cloth is attached to a bottom face of the water tank for receiving the water discharged through the discharging port. A pressing mechanism is configured to selectively press and translate the deformable member.
