A floor cleaner including a base movable over a surface to be cleaned, a suction nozzle provided on the base having a suction inlet, a body portion having a fluid dispensing member selectively removable from the body portion, the body portion being pivotally mounted to the base movable between an upright storage position and an inclined floor cleaning position, a suction source in fluid communication with the suction nozzle, and a reservoir configured to provide solution. The fluid dispensing member includes a grip, a dispensing nozzle in fluid communication with the reservoir, and an actuator. The fluid dispensing member is configured to deliver solution from the reservoir through the dispensing nozzle upon user actuation of the actuator, independent of function of the base and body of the floor cleaner.

A surface cleaning apparatus includes a housing, a fluid delivery system including a supply tank removably mounted on the housing and a fluid distributor, a fluid recovery system having a recovery tank removably mounted on the housing, an extraction nozzle, a motor/fan assembly, and a supply tank receiver provided on the housing for receiving the supply tank and comprising a void at least partially defining a seat for the supply tank.

Self-cleaning features for extraction cleaners and attachments for extraction cleaners, such as accessory tools, wands, and/or hoses, are provided. The self-cleaning features are configured redirect cleaning fluid from a fluid supply system of the extraction cleaner into a working air or fluid recovery path of the extraction cleaner, including, but not limited to into the working air or fluid recovery path of a tool, wand, and/or hose of the extraction cleaner.

A mobile robot configured to travel across a residential floor or other surface while cleaning the surface with a cleaning pad and cleaning solvent is disclosed. The robot includes a controller for managing the movement of the robot as well as the treatment of the surface with a cleaning solvent. The movement of the robot can be characterized by a class of trajectories that achieve effective cleaning. The trajectories include sequences of steps that are repeated, the sequences including forward and backward motion and optional left and right motion along arcuate paths.

A floor washer cleaning device is mounted inside an opening cavity arranged at a bottom of a dustbin of the floor washer. The floor washer cleaning device comprises a roller brush assembly rotatably arranged inside the opening cavity, and a scraping board fixed at the bottom of the dustbin and located at an edge of a side of a bottom of the opening cavity. The scraping board, an inner wall of the opening cavity, and the roller brush assembly cooperatively enclose to form a negative pressure cavity communicating with the dustbin, and a suction nozzle communicating with the negative pressure cavity is formed between an inner side of the scraping board and the roller brush assembly.

In a nozzle block, a fluid is uniformly sprayed over an entire housing inside through a spray nozzle with the rotation of a nozzle coupling part, thereby increasing a contact ratio of the fluid with contaminated gas and dramatically improving the purification efficiency. Additionally, a fluid for cleaning contaminated gas is allowed to flow opposite to a flow of contaminated gas, so that the contaminated gas and the fluid cancel out, and the contact ratio increases.

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.
