A portable surface treatment tool is provided, which is configured for attachment to a suction controller. The portable surface treatment tool is configured for use with vertical, overhead, inclined and horizontal surfaces and includes a head and a handle coupled to the head. The head includes: a rotatable surface treatment unit configured to engage a surface to be treated; a motor configured to drive the rotatable surface treatment unit; and a shroud substantially encasing at least a portion of the rotatable surface treatment unit, the shroud defining a suction region proximal the rotatable surface treatment unit. The suction region is configured to suck fluid from a surface to be treated. The shroud defines a suction connection formation configured to be coupled to a source of suction supplied by a suction controller, the suction connection formation being in fluid communication with the suction region to remove fluid from a surface to be treated.

In one aspect, an autonomous cleaning robot includes a drive configured to propel the robot along the floor surface and a tank assembly. The tank assembly includes a reservoir, left and right receptacles, and a handle extending across a cover of the tank assembly, the handle being moveable between a first position and a second position, wherein when the handle is in the second position, the tank assembly is locked in position. The tank assembly also includes left and right latch assemblies receivable by the left and right receptacles, respectively. Each latch assembly includes a moveable assembly configured to lock the tank assembly in position when the handle is in the second position.

A driving mechanism for an autonomous planar surface cleaning robot is disclosed. The driving mechanism includes a first transmission component and a second transmission component spaced apart in parallel relationship relative to the first transmission component. Each of the first and second transmission components defines first and second ends and first and second sides, wherein the first sides face each other and the second sides face away from each other in a direction transverse from the direction of motion and the first and second ends are oppositely spaced along the direction of motion. Each of the first and second transmission components are independently controllable by a control unit of the autonomous planar surface cleaning robot.

A portable surface cleaning apparatus for a floor surface includes a recovery tank and a supply tank separated by a partition, and further includes a carry handle defining a handle grip spaced above the supply and recovery tanks, wherein the handle grip does not intersect the supply tank or the recovery tank.

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.

A hand vacuum cleaner has a suction motor and fan assembly having a suction motor axis of rotation, an air treatment member having an openable door and a central longitudinal axis extending between the front and rear ends of the air treatment member; and, a handle having a having a hand grip portion wherein the hand grip portion extends upwardly and forwardly when the hand vacuum cleaner is oriented with the upper end of the hand vacuum cleaner above the lower end of the hand vacuum cleaner. The central longitudinal axis intersects the openable door and the hand grip portion.

A surface cleaning apparatus is operable in a plurality of cleaning modes, including at least a wet cleaning mode and a dry vacuuming mode. The surface cleaning apparatus has a suction source, a suction inlet port in fluid communication with the suction source, a fluid dispenser, a pump in fluid communication with the fluid dispenser, a motor coupled with a brushroll to drive the brushroll, and a floor type sensor. Operating parameters of the apparatus may be automatically adjusted based on a detected floor type.

A roller assembly tool for a cleaning apparatus that includes a suction assembly and a liquid delivery system includes a support body carrying a portion of a liquid conduit and a portion of at least one airflow passage. The liquid conduit is configured to be in fluid communication with the liquid delivery system and the portion of the at least one airflow passage configured to be in fluid communication with the suction assembly. The support body includes first and second arcuate guides that define an open end. A roller is rotatably coupled to the support body proximate the open end. At least one inlet of the at least one airflow passage is defined between at least one of the first and second arcuate guides and a surface of the roller. An outlet of the liquid conduit is defined between the first and second arcuate guides proximate the roller.

A bidirectional cleaning machine includes a cleaning mechanism and a handle. The cleaning mechanism includes a housing, a transmission shaft is mounted in the housing, a first gear is arranged on the transmission shaft, and one end of the transmission shaft is fixedly connected to an inner cleaning disk; the transmission shaft is sleeved with a transmission sleeve, and one end of the transmission sleeve is perpendicularly and fixedly connected to an outer cleaning ring; a base gear is fixedly arranged on the transmission sleeve, and a fixed gear is fixedly arranged in the housing; connecting shafts are perpendicularly arranged on the base gear, and each connecting shaft is sleeved with a second gear and a third gear; a power mechanism is arranged on the housing; clamping rings configured as circular structures are arranged a side face of the housing, teeth are distributed on inner sides of the clamping rings.

A fluid suction device includes an elongate handle having a suction head at its distal end. The suction head extends in opposing directions substantially perpendicularly to the handle. The suction head includes an elongate longitudinal aperture in its outer wall in fluid communication with a suction pump. An absorbent panel covers the longitudinal aperture. When the suction head is applied to a spilled fluid, the wicking action of the absorbent panel and the negative air pressure from the suction pump allows rapid and efficient cleaning of an area affected by a fluid spill. The device also allows for safe and efficient removal of potentially dangerous objects such as broken glass. The device collects fluid in a waste reservoir so that it is easily disposed of.
