A vertical surface cleaning device comprising a main body, a cleaning arm, a cleaning head, and leg mechanisms with grippers. The cleaning head applies a cleaning fluid on a surface to carry out a cleaning operation. A waste collector is provided to collect a waste material arising from the cleaning operation. The grippers may remain in a grip or in a release state. The segments of the leg mechanisms are articulatable to configure a first group of the leg mechanisms to stably hold the main body at a first place with the grippers remaining in the grip state. A second group of the leg mechanisms move in a desired direction with their grippers in release state while the first group stably holds the main body. The first group of the leg mechanisms then moves in the same direction while the second group holds the main body at a second place.

A surface cleaning apparatus including, a fluid storage container; an outlet for directing fluid from the fluid storage container onto a surface to be cleaned; and a valve configured to regulate the flow of fluid from the fluid storage container to the outlet and including: a body; and a member being moveable relative to the body between a first position and a second position and defining a flow path extending through a surface thereof; wherein the flow of fluid through the valve flows at a first rate when the member is in the first position and at a second rate and along the flow path when the member is in the second position, the second rate of flow being lower than the first rate of flow.

The present disclosure provides a surface cleaning apparatus that includes a recovery system that extracts liquid and debris with a drying cycle in which forced air flows through a recovery pathway of the recovery system to dry out components that remain wet and/or retain moisture after normal operation of the apparatus. The post-operation drying cycle can dry out components such as an agitator or brushroll, a brush chamber, a suction nozzle, a recovery tank, a filter, and any of the various conduits, ducts, and/or hoses fluidly coupling components of the recovery system together.

The present disclosure provides a floor cleaner that includes a replaceable component, such as a brushroll or a filter. The floor cleaner has a detection mechanism comprising a magnet on the replaceable component and a Hall Effect sensor positioned to detect the permanent magnet when the replaceable component is correctly installed on the floor cleaner. Operation of one or more electrically-powered components of the floor cleaner is prevented when the permanent magnet is not detected by the Hall Effect sensor.

A supply device for supplying a device that can be moved on a driving surface with a material supplied through a supply line. The supply device has a plug with an electric plug contact element that extends along a plug axis and is coupled to a plug receptacle of the mobile device by a linear joining movement, and a supply line with a valve, and detects a coupled state of the plug with the plug receptacle by an electric plug contact element. In the coupled state the valve is actuated. The supply device has a nozzle arranged on the supply line and is coupled to an inlet port of the mobile device. A feeding holder keeps the nozzle and the plug in a defined position and orientation relative to each other so that when coupling the plug to the plug receptacle the nozzle couples to the inlet port. The movement device makes the feeding holder with the plug and nozzle at least height adjustable and movable in the direction of the joining movement along a joining axis. The detection system determines a position of the plug receptacle. The supply device couples the plug to the plug receptacle and thereby the nozzle to the inlet port by a linear joining movement along the joining axis based on the determined position.

A handheld extraction cleaner includes a unitary body provided with a carry handle, and further provided with a supply tank, a recovery tank, and a suction source, all of which are carried on the unitary body. The various components of the extraction cleaner can be arranged for a balanced weight in hand. The supply and recovery tanks are configured to optimize the usable volume within the tanks, among other functions. A powered cleaning head including a removable brushroll is provided on the unitary body.

An autonomous coverage robot detection system includes an emitter configured to emit a directed beam, a detector configured to detect the directed beam and a controller configured to direct the robot in response to a signal detected by the detector. In some examples, the detection system detects a stasis condition of the robot. In some examples, the detection system detects a wall and can follow the wall in response to the detected signal.

A cleaning robot and an automatic cleaning method thereof, to implement automatic cleaning. The cleaning robot includes a lifting mechanism and a cleaning base, where the cleaning base includes a base body, a scraping mechanism disposed on the base body, and a spraying assembly provided with nozzles. The nozzles are arranged along a mopping component of the cleaning robot and formed into a structure for spraying water or mist to the mopping component. The scraping mechanism includes a scraper, and the scraper comes into contact with and moves relative to the mopping component, to scrape off the attachment on the mopping component while squeezing out the water. The lifting mechanism causes the mopping component to lift or move down by causing the mopping component to come into contact with or separate from the scraper.

A surface cleaning apparatus, such as a carpet extractor, includes a base and a fluid recovery system for drawing dirty cleaning fluid from a surface to be cleaned. The fluid recovery system includes a suction nozzle in fluid communication with a recovery chamber. The suction nozzle is mounted to the base for vertical movement with respect to the base and is biased into contact with the surface to be cleaned.

The present invention relates to a control device for a robot cleaner providing functions and user interfaces (UI) for increasing user convenience, and according to the control device of the present invention, the user convenience can be increased by providing various user interfaces capable of receiving set values for controlling the robot cleaner.
