A floor washer cleaning device is mounted inside an opening cavity arranged at a bottom of a dustbin of the floor washer. The floor washer cleaning device comprises a roller brush assembly rotatably arranged inside the opening cavity, and a scraping board fixed at the bottom of the dustbin and located at an edge of a side of a bottom of the opening cavity. The scraping board, an inner wall of the opening cavity, and the roller brush assembly cooperatively enclose to form a negative pressure cavity communicating with the dustbin, and a suction nozzle communicating with the negative pressure cavity is formed between an inner side of the scraping board and the roller brush 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.

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.

A surface cleaner is provided. The surface cleaner comprises: an operating component configured to perform a function of the surface cleaner; a base moveable along a surface; an accelerometer configured to generate a signal; and a controller in communication with the accelerometer and the operating component, wherein the controller is operable to control the operating component based on the signal, and wherein the operating component is selected from a group consisting of a suction motor operable to generate an airflow, a brushroll motor operable to drive a brushroll, an actuator operable to adjust a height of a brushroll from the surface, a pump operable to deliver a cleaning fluid, an actuator operable to control an airflow or fluid valve, and an indicator operable to indicate a parameter of the surface cleaner.

The present disclosure discloses an automated floor cleaning apparatus, has an automatic cleaning robot and a washing base; the rear end of the robot body of the automatic cleaning robot is provided with a mop mechanism, the mop mechanism comprises a rotation component rotatably connected to the robot body and a crawler-type wiping cloth sleeving outside and rotating along with the rotation component. The invention provides can automatically and effectively removes dirt attached to the crawler-type wiping cloth, avoiding artificial detaching and then cleaning the wiping cloth stained with dirt, automatically performing washing operation, greatly alleviating operation burden of a user, and having a good floor sweeping effect.

The present invention relates generally to an apparatus for cleaning or otherwise treating a floored surface that includes a platform adapted to support the weight of an operator. In addition, one embodiment of the present invention is capable of generally performing 360° turns to facilitate the treatment of difficult to access portions of the floored surface.

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.

A surface-cleaning machine is provided, which includes an appliance body on which a suction apparatus device is arranged, a cleaning head on which at least one cleaning roller is arranged, and a drive device for driving the at least one cleaning roller in rotation, wherein the cleaning head has, between a first face side and an oppositely situated second face side, a first region, a second region and a central region situated between the first and second regions, and wherein at least one first suction mouth is positioned at the first region and associated with the at least one cleaning roller and at least one second suction mouth is positioned at the second region and associated with the at least one cleaning roller, wherein the at least one first suction mouth and the at least one second suction mouth are fluidically connected to the suction apparatus device.

A surface-cleaning machine is provided, including an appliance body on which a suction apparatus device is arranged, a cleaning head on which at least one cleaning roller is arranged and on which there is positioned at least one suction mouth, which is fluidically connected to the suction apparatus device and is associated with the at least one cleaning roller, and a drive device for driving the at least one cleaning roller in rotation, wherein a drive axis of a drive motor of the drive device and an axis of rotation of the at least one cleaning roller are oriented transversely and in particular perpendicularly with respect to one another.

A surface cleaning machine including at least one cleaning roller, a drive device for rotary driving of the at least one cleaning roller, a wetting device for applying cleaning liquid to the at least one cleaning roller, and a suction unit arrangement for generating a suction stream is provided. The suction unit arrangement is fluidically connected to at least one suction duct and at least one suction nozzle that is associated with the at least one cleaning roller. The wetting device includes at least one pressure-controlled switch that opens a fluid path for cleaning liquid to the at least one cleaning roller and shuts off the fluid path, and the at least one pressure-controlled switch is coupled to the at least one suction duct, wherein a suction stream in the at least one suction duct moves the pressure-controlled switch into the open position and/or maintains the open position.
