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.

A cleaning device includes: a main body having a roller apparatus and a suction apparatus, the roller apparatus defining a line of movement of the cleaning device, the suction apparatus opening out into a suction opening which is arranged on a side of the main body facing a floor to be cleaned, the suction opening being bordered by a first wall and a second wall, the first wall and the second wall running transversely to a line of movement. A lip with an elastic design, which when the cleaning device is used as intended lies on the floor to be cleaned, is assigned to the suction opening. When the cleaning device is moving in a first direction of movement along the line of movement, the lip rests against the first wall.

A vertical household floor scrubber is provided, including: a base, where a traveling wheel and a cleaning component are disposed on the base; a floor scrubber body disposed on the base and capable of rotating relative to the base to help the cleaning component to perform a cleaning operation, where a mounting portion is disposed on the floor scrubber body, and one side of the mounting portion away from the base is provided with a mounting groove; a rechargeable battery, where the rechargeable battery is detachably mounted in the mounting groove, and the rechargeable battery is electrically connected to a component in the mounting portion; and a mounting structure, where the mounting structure is disposed between the rechargeable battery and the mounting groove, and the mounting structure is configured to implement detachable assembly between the rechargeable battery and the mounting groove.

A floor cleaner includes a handle, a body, a base movable over a surface to be cleaned, and a supply tank coupled to the body. The supply tank having an inlet opening defining an inlet opening width and a fluid disposed therein. A water soluble package includes a cleaning solution disposed therein and is inserted within the supply tank to combine with the fluid disposed therein to form a cleaning fluid. A distribution nozzle is in communication with the supply tank and disperses the cleaning fluid towards a ground surface. The package has an unfolded dimension defined by a first width that is larger than the inlet width, a height defined orthogonal to the first width, and a thickness defined orthogonal to the first width and the height. The package folds from the unfolded dimension to a compact size having a folded dimension defined by a second width that is smaller than the inlet opening width.

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 floor cleaning machine with a filter unit for a suction connector in a dirty-water tank. The filter unit has a substantially sleeve-shaped main body, which has an inlet opening at a face end, a substantially annular float body, which is arranged around and is displaceable along the main body between a closed position and an open position, a cover, which is arranged on the face end and has an entry opening that is configured to be selectively closed off by the float body. A fluid channel is provided in the cover and is configured to allow a fluid to flow from the entry opening into the inlet opening, and a sleeve-shaped filter element. The float body is arranged around the main body in an annular space between the main body and the filter element.

A handheld extraction cleaner includes a unitary body provided with a carry handle, and further provided with a supply tank, a suction nozzle, a recovery tank, and a suction source, all of which are carried by the unitary body. In one aspect, the recovery tank is configured to optimize the usable volume within the tank and a user's view of the collected dirty liquid within the tank, among other functions. In another aspect the recovery tank has an auto-close feature that automatically seals an outlet of the tank when the recovery tank is mounted to a tank receiver of the unitary body. In yet another aspect, the extraction cleaner has an agitator that slides out from a side of the unitary body. In still another aspect, the suction nozzle includes a cleaning angle guide skid to orient the extraction cleaner at an optimal cleaning angle. In a further aspect, the supply tank is a non-removable part located at a rear of the unitary body.
