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 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.

The invention relates to a cleaning device, in particular a suction wiper, having a housing with at least one cleaning medium for receiving a cleaning agent, having a cleaning medium carrier for receiving the cleaning medium, having a drive for driving the cleaning medium carrier and having a controller. At least one vibration sensor for detecting a strength of a vibration is arranged in the housing and the controller is designed to determine the moisture of the cleaning medium, the controller evaluating a change in the strength of the vibration. The invention also relates to a method for operating a cleaning device.

A nozzle for a cleaner has a nozzle housing, which has a nozzle base and a drain hole for discharging water from the nozzle housing. The nozzle also has a rotary cleaning unit disposed below the nozzle housing. The rotary cleaning unit has a rotation plate that can be attached to a mop. The nozzle has a driving unit that includes a driving motor for driving the rotary cleaning unit The nozzle also has a control board for controlling the drive motor. In addition, the nozzle has a water tank detachably mounted on an upper side of the nozzle housing. The water tank stores water and supplies the water to the rotary cleaning unit

A surface treatment robot includes a chassis having forward and rear ends and a drive system carried by the chassis. The drive system includes right and left driven wheels and is configured to maneuver the robot over a cleaning surface. The robot includes a vacuum assembly, a collection volume, a supply volume, an applicator, and a wetting element, each carried by the chassis. The wetting element engages the cleaning surface to distribute a cleaning liquid applied to the surface by the applicator. The wetting element distributes the cleaning liquid along at least a portion of the cleaning surface when the robot is driven in a forward direction. The wetting element is arranged substantially forward of a transverse axis defined by the right and left driven wheels, and the wetting element slidably supports at least about ten percent of the mass of the robot above the cleaning surface.

A surface cleaning apparatus such as an extractor has a fluid flow path extending from a dirty fluid inlet head to a clean air outlet. The fluid flow path upstream of the separation stage comprises a removable portion.

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.

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 robot cleaner includes a main body, a moving unit for moving the main body, a cleaning module capable of being brought into contact with a floor surface at at least part of a lower surface thereof, and a module drive unit for controlling an angle of inclination of the lower surface of the cleaning module with respect to the floor surface.
