A portable surface cleaning apparatus for a floor surface includes a main housing assembly adapted to be hand carried by a user, the main housing assembly carrying a fluid delivery system adapted for storing cleaning fluid and delivering the cleaning fluid to the surface to be cleaned, and a fluid recovery system adapted for removing the cleaning fluid and debris from the surface to be cleaned and storing the cleaning fluid and debris that was recovered, the main housing assembly comprising a base housing, a supply tank received on the main housing assembly, a recovery tank received on the main housing assembly separately from the supply tank.

An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arranged to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

Provided is a wet cleaning apparatus (10), such as a wet vacuum cleaner. The wet cleaning apparatus comprises a dirt inlet (11), and a motor (14) and fan (16) for delivering suction to the dirt inlet. A separator unit (18) separates water from a flow of air generated by the suction. The apparatus further includes a container (19) for collecting the separated water. The container has a top (19A) and a bottom (19B). An air passage (22) is provided in the container for passing the air separated from the water towards the motor and fan. The air passage is spatially separated from the bottom of the container. An internal wall (19E) extends from the top towards the bottom of the container. A space (25) is thus defined between the container and the internal wall. Water collected at the bottom of container is receivable in the space when the container is orientated, e.g. tilted, such that the collected water moves from the bottom towards the top of the container. The internal wall is arranged to prevent water received in the space from passing into the air passage.

A floor cleaner including a recovery tank. The recovery tank includes a tank body having a lower end wall, an open upper end, and a sidewall that extend upwardly from the lower end wall. A cover that includes a suction air outlet in fluid communication with a vacuum source. An inlet duct extends upwardly from the lower end wall. The recover tank includes a shutoff float including a float body and a closure. The float body is configured to float on a surface of cleaning fluid and the closure is received in the suction air outlet to close the suction air outlet. The float body moves along the inlet duct as the float body floats on the surface of the cleaning fluid. The float body includes an aperture extending through the float body and the inlet duct extends through the aperture of the float body.

An extraction cleaner includes a suction nozzle having an inlet path and suction fan configured to provide suction. The inlet path brings liquid and air into the extraction cleaner. Suction fan has a fan entrance, a recovery tank is spaced from the fan entrance. A separator element configured to allow liquid to flow into the recovery tank, inhibit the flow of liquid out of the recovery tank, and inhibit liquid from reaching the fan entrance, or all three. The separator element may be a butterfly valve configured to selectively close the fan entrance. The separator element may be a funnel extending into the recovery tank to block liquid from leaving the recovery tank during inversion. The separator element may be a fan separator adjacent the suction fan, which directs liquid outward, away from the fan separator, within the extraction cleaner, such that liquid is moved away from the suction fan.

A cleaning device and methods for cleaning are provided. In one embodiment, the cleaning device includes a head assembly, a body assembly, and a handle assembly. The cleaning device also includes components that enable the cleaning device to operate in dry cleaning modes and wet cleaning modes. Dry cleaning modes can employ a vacuum assembly, including a motor, tubing, and a fluid recovery tank in order to draw in debris and waste into a fluid recovery tank. Wet cleaning modes can further employ a fluid supply tank, a pump, and tubing in order to supply fluid to a brushroll to aid in a cleaning process.

A floor cleaner including a vacuum source recovery tank or collection bin and a body pivotally coupled to a base. The body is pivotable between an upright storage position and an inclined operating position and the body includes a recovery tank recess. The floor cleaner further includes a recovery tank removably coupled to the body in the recovery tank recess, the recovery tank in fluid communication with a vacuum source and a suction inlet, the recovery tank configured to store the cleaning fluid and/or debris drawn through the suction inlet from a surface by the vacuum source. The floor cleaner further includes a projection and a recess that receives the projection when the recovery tank is coupled to the body to limit movement of the body relative to the recovery tank.
