An autonomous floor cleaner can include a housing, a drive system for autonomously moving the housing over the surface to be cleaned, and a controller for controlling the operation of the autonomous floor cleaner. The drive system can include at least one drive wheel for driving the housing across a surface to be cleaned. The drive wheel can be selectively moved from an engaged or in-use position to a disengaged or maintenance position. In the disengaged or maintenance position, the wheel is disengaged from the autonomously moveable housing such that it can be pivoted, extended, removed, or otherwise moved farther away from the autonomously moveable housing.

A portable cleaner has a recovery tank, including a container for receiving and storing recovered liquid and/or dirt and an openable tank lid for covering the container. The container and the tank lid are removable from the cleaner as a unit. The portable cleaner also has a main housing configured to removably support the recovery tank in a vertical orientation in which the tank lid at least partially defines a top side of the portable cleaner. In addition, a tank latch is provided in the tank lid, the tank latch configured to selectively secure and release the tank lid to the main housing when the recovery tank is supported by the main housing.

A surface cleaning apparatus includes a housing having a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. Various motor cooling arrangements are disclosed. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft floor surfaces.

A floor cleaning machine including a handle that pivots relative to a base about a pivot axis. A recovery tank is coupled to the handle in fluid communication with a suction motor assembly to receive and store fluid and dirt drawn through a suction nozzle. The floor cleaning machine further includes an expandable hose fluidly communicating the recovery tank and the suction nozzle. The hose is in an expanded configuration when the handle is pivoted about the pivot axis to a reclined position. The hose is in a retracted configuration when the handle is pivoted about the pivot axis to a substantially upright position. The hose at least partially wraps around the pivot axis with the pivot axis being between a portion of the hose wrapped around the pivot axis and the surface being cleaned in the expanded and the retracted configurations.

A wet surface cleaner operable in an upright cleaning mode, an auxiliary cleaning mode, and a lift-off cleaning mode. The surface cleaner has a canister assembly that is coupled to a body in the upright cleaning mode and removed from the body in the auxiliary cleaning mode and the lift-off cleaning mode.

A cleaning device includes a rolling brush mounted on a housing and can be in rolling contact with the ground. A waste collection region is integrally or separately provided in the housing, and the waste collection region is provided with a collection inlet provided corresponding to the rolling brush. Waste brought up by the rolling contact is collected into the waste collection region under the rotation action of the rolling brush. The housing is provided with one or more scraping guiders connected to the collection inlet, and each of the scraping guiders is in flexible pressure contact with the rolling brush or the ground, and is configured to scrape off residual waste absorbed by the rolling brush or residual waste on the ground and transfer the residual waste into the waste collection region.

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 disclosure relates to an autonomous cleaning robot. The autonomous cleaning robot may include a main body (1) and a cleaning assembly. The cleaning assembly is mounted on the main body (1). The cleaning assembly may include a first cleaning subassembly (2) removable and provided on the main body (1). The first cleaning subassembly (2) is moved in the forward direction or the backward direction of the main body (1) when the first cleaning subassembly (2) is loaded or removed from the main body (1). The first cleaning subassembly (2) is removable and connected to the main body (1) through a connecting member.

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.
