The present disclosure provides a floor cleaner that includes a replaceable component, such as 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 portable foam brush assembly having a base having a soap supply, a water supply, and an electrical supply. A foam brush wand is detachably dockable to the base and in electrical and fluid communication with the foam brush wand having battery pack, a peristaltic pump, a reservoir chamber, a foaming chamber, an air pump, a brush and a momentary release switch. The base water supply and the base soap supply, when activated, are configured to travel by a water supply hose and a soap supply hose to a tee in the base where they are combined in a combined hose to a base quick coupler that is connectable to a reciprocal foam brush wand quick coupler, which has a foam brush wand hose to deliver the water soap mixture to bladder in the foam brush wand.

An extractor includes a fluid recovery system including a suction nozzle, a recovery tank assembly, and a suction source having an inlet fluidly connected to the recovery tank assembly and the suction nozzle through an air conduit and adapted to draw liquid through the suction nozzle and deposit the liquid in the recovery tank assembly. The extractor includes a body provided with the air conduit for movement between a first position wherein suction is unreduced and a second position wherein suction is reduced. The extractor includes a fluid delivery system including a solution supply tank assembly, a fluid distributor, and a conduit for depositing fluid onto a surface. The extractor includes a hydraulic connector operably coupled to the body and adapted to move the body between the first and second positions.

A surface cleaning apparatus includes a recovery tank, a suction nozzle in fluid communication with the recovery tank, and a suction source in fluid communication with the suction nozzle and the recovery tank to generate a working air path to transport debris-containing fluid including air and liquid from the suction nozzle into the recovery tank. An air/liquid separator can be provided within the recovery tank for separating liquid from air in the debris-containing fluid.

Disclosed is a cleaner capable of autonomously traveling while performing a mopping task, the cleaner including: a body which defines an exterior appearance of the cleaner; at least one mop module which has at least one mop provided in contact with a floor, and which supports the body against the floor; and a tilt information acquisition unit configured to acquire tilt information of the body in relation to the floor. At least one specific part may comprise the at least one mop, may be a whole or part of the at least one mop module, and may be defined such that the at least one specific part is provided detachable from other parts of the cleaner except for the at least one specific part and that the body tilts in relation to the floor due to gravity while the at least one specific part is separated from the other parts. The cleaner may further comprises a controller which is configured to: based on at least the tilt information, determine satisfaction or unsatisfaction of a predetermined separated condition that is preset to be satisfied when the specific part is separated from the other parts; and, when the detachments condition is satisfied, control a predetermined mop separation error response operation.

An apparatus for cleaning a surface includes a liquid delivery system for storing cleaning liquid and delivering the cleaning liquid to the surface to be cleaned, a fluid recovery system and a control system. The control system includes a controller that is coupled to a fluid level sensing assembly. Methods of operating the same include sensing foam or liquid with the fluid level sensing assembly.

A method of controlling a moving robot is provided. The method of controlling a moving robot includes the steps of: (a) performing a basic motion of the moving robot which moves on a rotating mop; (b) measuring the slip rate of the moving robot; and (c) controlling the travel of the moving robot.

A floor cleaning and polishing device has a polishing pad for a surface which is rotationally engaged upon a pad driver operatively engaged to a frame. A first set of wheels on the frame allow for tilted movement. A second set of wheels are positionable to a deployed position to elevate the first set of wheels from the surface and position the polishing pad parallel to the surface. The device may have a light projector engageable for light disinfecting. The polishing pads are configured with a plurality of polishing fabric sections separated by recesses therebetween.

In a dosage system for delivering a predetermined amount and type of cleaning concentrate to a solvent inside a fluid tank, a pod holder is configured to form an inner volume for holding a pod containing the cleaning concentrate. A connector is configured to form a fluid connection between the inner volume of the pod holder and the inside of the fluid tank. A piercing device is configured to pierce the pod held by the pod holder. A push mechanism is configured to push the piercing device into the inner volume of the pod holder for piercing the pod to release the cleaning concentrate from the pod via the fluid connection of the connector into the inside of the fluid tank.

An autonomous floor cleaner can include a housing, a drive system for autonomously moving the housing over the surface to be cleaned, a controller for controlling the operation of the autonomous floor cleaner, a tank adapted to hold liquid, and a carry handle joined with the tank and/or the housing. The carry handle is movable between different positions, including a position in which the autonomous floor cleaner can be lifted via the carry handle while an inlet and/or outlet of the tank is blocked.
