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.

A cleaning machine may include: a first brush including a first brush shaft and a first brush body held by the first brush shaft; a second brush including a second brush shaft and a second brush body held on the second brush shaft; a first brush attaching member having a first shape, wherein one end of the first brush shaft is detachably attached to the first brush attaching member; and a second brush attaching member having a second shape, wherein one end of the second brush shaft is detachably attached to the second brush attaching member. The one end of the first brush shaft may have a first corresponding shape that corresponds to the first shape. The one end of the second brush shaft may have a second corresponding shape that corresponds to the second shape. Other end of the first brush shaft may have the second corresponding shape.

A management device simultaneously clamps both the power cord and the vacuum tube of a floor preparation machine to appropriately direct the power cord and vacuum tube and protect from damage the power cord, vacuum tube cord plug and machine socket associated with the power cord and fitting associated with the vacuum tube.

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 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.

A surface cleaning machine is provided, including a cleaning roller holder, a cleaning roller that is arranged on the cleaning roller holder, a drive device for rotary driving of the cleaning roller, and a sweeping element that is associated with the cleaning roller and supplies swept material to the cleaning roller, wherein the sweeping element is arranged rotatably on the cleaning roller holder.

An autonomous cleaning robot (e.g., an autonomous vacuum) may clean an environment using a cleaning head that is self-actuated. The cleaning head includes an actuator assembly comprising an actuator configured to control rotation and vertical movement of a cleaning roller, a controller, and a cleaning roller having an elongated cylindrical length connected to the actuator assembly. The cleaning head also includes a computer processor connected to the actuator assembly and a non-transitory computer-readable storage medium that causes the computer processor to map the environment based on sensor data captured by the autonomous vacuum. The computer processor may determine an optimal height for the cleaning head based on the map and instruct the actuator assembly to adjust the height of the cleaning head.
