A dirt removing device including: a cassette mechanism having a head formed with a beating face, a liquid accommodating portion for accommodating liquid, and a water supplying passage which is started from the liquid accommodating portion and penetrates into the entire head; and a device body having a vibration unit. The cassette mechanism is detachably received in the vibration unit, and the vibration unit, when being powered, causes the cassette mechanism to vibrate in a direction substantially orthogonal with the beating face of the head. The liquid is supplied from the liquid accommodating portion to the beating face of the head through the water supplying passage, along with the vibration of the cassette mechanism caused by the vibration unit.

A floor cleaning apparatus includes a floor cleaning apparatus body. A first tank is removably received by the vacuum cleaner body. A cartridge is removably received by the first tank. The cartridge releasably stores chemical elements. A first electrical contact is disposed in the floor cleaning apparatus body. A second electrical contact is disposed in the first tank. The second electrical contact is electrically connected to the first electrical contact when the floor cleaning apparatus body receives the first tank. Electrical power is configured to be supplied to the first electrical contact to release the chemical elements stored in the cartridge into water stored in the first tank. The supplied electrical power is configured to cause electrolysis of the water and the chemical elements in the first tank to produce a cleaning solution in the first tank.

An apparatus for cleaning a floor includes a housing, wheels by which the apparatus is adapted to move; a motive device for moving the apparatus, a steering mechanism, and a cleaning assembly including a cleaning unit and an offset mechanism adapted to move the cleaning unit to or from an offset position projecting beyond one lateral side of the apparatus. In another embodiment, an apparatus for cleaning a floor includes a housing, wheels by which the apparatus is adapted to move, a motive device for moving the apparatus, a steering mechanism, and a cleaning assembly including a cleaning unit and a swing mechanism indirectly linking the cleaning unit to the steering mechanism such that when the apparatus is in an operative mode, the cleaning unit reorients its position in synchronization with the path of travel of the apparatus. Optionally, a lifting device may raise and lower the cleaning assembly.

A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the upright handle assembly and adapted for movement across a surface to be cleaned. The surface cleaning apparatus is further provided with a fluid delivery system comprising a fluid dispenser configured to dispense fluid to a brushroll and at least one fluid delivery channel forming a portion of a fluid delivery pathway. The fluid delivery channel can extend adjacent to a portion of the suction nozzle assembly. An interference wiper interfaces with a portion of the brushroll to remove excess liquid from the brushroll.

An extractor includes a base movable along a surface having an agitator. The extractor also includes a distribution nozzle, a suction nozzle, and a suction source in fluid communication with the suction nozzle and operable to draw fluid and dirt from the surface, a recovery tank in fluid communication with the suction source to receive and store the fluid and dirt drawn, a supply tank supported by the base and in fluid communication with the distribution nozzle to supply cleaning fluid, a pump in fluid communication with the supply tank and the distribution nozzle to deliver fluid from the supply tank to the distribution nozzle, a motor operable to drive the agitator and the pump, and a drive mechanism coupled to the motor, the agitator, and the pump and operable to selectively connect the agitator and the pump to the motor to alternately drive the agitator and the pump.

Aspects of the present invention relate to a triggerless extractor surface cleaning device for cleaning a surface in which a cleaning solution is distributed to the surface and extracted using suction along with dirt and/or debris on the surface in a continuous operation as the extractor moves along the surface. The extractor further comprises an encoder positioned adjacent a wheel of the extractor for detecting a rotational direction and speed of the wheel to generate a signal. Based on receiving the signal, a controller controls operation of a valve to situationally distribute the cleaning solution to the surface depending on a forward rotation of the wheel and independent of user actuation of a trigger positioned on a handle used to propel the extractor along the surface. Distribution of the cleaning solution can be further optimized based on the detected rotational speed of the wheel.

The cleaning robot includes a chassis; a fluid applicator carried on the chassis and configured to distribute a cleaning fluid on at least part of a cleaning width; a fluid storage apparatus detachably connected to the chassis, wherein the fluid storage apparatus is in communication with the fluid applicator and configured to apply the cleaning fluid distributed by the fluid applicator to a ground; an in-position sensor disposed in a recess of chassis in which the fluid storage apparatus is mounted and configured to detect whether the fluid storage apparatus is in position and report an in-position state signal of the fluid storage apparatus to a control system; and the control system carried on the chassis and configured to plan a cleaning path according to in-position state signal of the fluid storage apparatus and control fluid applicator to distribute the cleaning fluid according to the cleaning path
