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.

An extraction cleaner for a floor surface includes an extraction nozzle. The extraction nozzle that defines a fluid flow path having an elongated nozzle opening, and includes one or more stiffening elements that stiffens the walls around the nozzle opening to prevent collapsing or deformation of the extraction nozzle during use.

The present disclosure provides cleaning robot, including a cleaning agent mopping device (1), a cleaning agent absorbing device (2), a water wiping (3) and washing device (4), and a water absorbing device arranged in turn along a moving direction of the cleaning robot. Each time when the cleaning robot of the present disclosure works to clean the to-be-cleaned surface, the cleaning robot can perform the four steps including cleaning agent mopping, cleaning agent absorbing, water wiping and washing, and water absorbing, thus, both hydrolysable and non-hydrolysable stains can be effectively cleaned by the cleaning robot. Thus, the cleaning robot is very practical, easy to operate, and simple to use.

The present disclosure provides a surface cleaning apparatus that includes task lighting. The task lighting can be provided on a hand-carried body or housing of the surface cleaning apparatus. Power to the task lighting can be controlled by a switch. The task lighting can be adjustable relative to the hand-carried body, and can be directed to illuminate a desired location.

Cleaning equipment includesa water divider structure comprisinga pressuresource connected to a water supply tank, a water divider provided with a first distribution channel and a second distribution channel, wherein the first and second distribution channels both are connected with the pressuresource, anda first unidirectional valve connecting between the pressuresource and the water divider, wherein the first unidirectional valve connects through the pressuresource and the water divider under pressure formed when the pressuresource is activated. When there is residual water in the pipeline between the first unidirectional valve and the water divider structure, the first unidirectionalvalve can prevent the water in the water supply tank from being transported downstream. At this time, there is water in the pipeline downstream of the first unidirectionalvalve. One end is closed, and one end of the water divider structure is connected to the outside.

A mopping module and a cleaning head. The mopping module includes a water tank, a mopping cloth, and a water volume control mechanism. A water tank hole is provided at a bottom portion of the water tank; the water tank hole communicates with the interior of the water tank; the mopping cloth is provided outside the bottom portion of the water tank; the water volume control mechanism comprises a knob and a water control tray; and by controlling the cooperation between the water control tray and the water tank hole via the knob, the amount of water flowing from the water tank to the mopping cloth through the water tank hole is adjusted.

An accessory tool for use with a vacuum cleaner. The accessory tool has a hair removal system configured to collect hair from various surfaces to be cleaned, including soft surfaces such as upholstery, dog beds, pillows, and automobile interiors. The collected hair is gathered by the hair removal system and ingested via the vacuum cleaner.

An autonomous coverage robot includes a chassis, a drive system configured to maneuver the robot, and a cleaning assembly. The cleaning assembly includes a cleaning assembly housing and at least one driven sweeper brush. The robot includes a controller and a removable sweeper bin configured to receive debris agitated by the driven sweeper brush. The sweeper bin includes an emitter disposed on an interior surface of the bin and a receiver disposed remotely from the emitter on the interior surface of the bin and configured to receive an emitter signal. The emitter and the receiver are disposed such that a threshold level of accumulation of debris in the sweeper bin blocks the receiver from receiving emitter emissions. The robot includes a bin controller disposed in the sweeper bin and monitoring a detector signal and initiating a bin full routine upon determining a bin debris accumulation level requiring service.

A handheld cleaning device includes a surface-moving portion and an upright portion. The surface-moving portion is in contact with a surface to be cleaned and is connected with the upright portion. The upright portion is configured to move the surface-moving portion in a case in which the surface-moving portion is in operation. The handheld cleaning device further includes a power battery configured to supply power to the handheld cleaning device. The surface-moving portion further includes at least two non-coaxial brushrolls configured to clean stains on the surface to be cleaned. The rotation speed of each brushroll is less than 3000 r/min.

A mobile robot of the present disclosure includes a first pattern emission unit configured to emit a first patterned light downward and forward from the main body on a floor of an area to be cleaned; and an image acquisition unit configured to acquire an image of first patterned light emitted by the first pattern emission unit and incident on an obstacle. A pattern is detected from the acquired image to determine an obstacle, and a cliff is detected based on at least one of a shape or a position of the pattern in the image. The mobile robot may identify a travel path that does not lead to the cliff.
