Embodiments include a surface maintenance machine, comprising a maintenance tool chamber comprising a first side, a second side, a third side and a fourth side. A rotary broom is housed in the maintenance tool chamber and substantially enclosed by the first, second, third and fourth sides thereof. The rotary broom sweeps particulate from the surface. A vacuum system generates vacuum for drawing particulate swept by the rotary broom. The vacuum system is positioned proximal to the first side. A skirt assembly extends substantially around the second, third and fourth sides of the maintenance tool chamber. The skirt assembly has a vacuum passage defined therein and in fluid communication with the vacuum system to direct air flow into the vacuum passage, thereby drawing particulate into the vacuum passage and preventing particulate accumulation at portions of the second, third and fourth sides that are distal to the vacuum system.

A robotic device for providing vertical mobility has a payload is disposed inside a central compartment and supported by a skid. The skid can move up and down through latch and hook pairs to keep intimate contact with the surface and cross over bumps. The apparatus uses a flexible seal to create a reliable vacuum chamber. The flexible seal comprises a foam ring inside fabric pocket. A plurality of rod and spring strips are configured to apply a downward force to the flexible seal to conform with surface curvatures. The fabric pocket fills in the gaps or seams to maintain a vacuum. The air flows inside a manifold and passes through a filter to avoid debris from damaging the vacuum motor assembly.

A wet-cleaning appliance, in particular a wet mop, has a cleaning roller, which is mounted in a rotatable manner about a roller axis, and having a roller cover, which encloses the cleaning roller in the circumferential direction, at least in part, and has at least one movable covering element for optionally closing and/or releasing an opening region of the roller cover. In order to prevent residual liquid contained in the roller cover from dripping from the wet-cleaning appliance when the roller cover is opened, the movable covering element has a collecting unit, in particular a collecting container, which has a storage volume for collecting liquid that remains in the roller cover.

The present disclosure discloses a multifunctional cleaning machine. The multifunctional cleaning machine includes a housing, a pipe, a nozzle, a plurality of wheel assemblies and a locking means. The pipe connected to the housing, the pipe including a water inlet and a water outlet, the water inlet being located on an upper side of the housing, the water outlet being located on a lower side of the housing, and the water inlet being configured for connecting to a high pressure water source. The nozzle connected to the water outlet. The wheel assemblies rotatably connected to the housing by the connecting assembly. The locking means connected to the housing and configured for locking the wheel assembly.

This document describes a mobile cleaning robot that includes a chassis that supports a drive system, a debris collection volume; and a cleaning head formed to complete a bottom of the robot. The cleaning head includes a frame for affixing the cleaning head to the chassis, a monolithic housing having an interior cavity, a suspension linkage movably suspending the monolithic housing from the frame, the suspension linkage being configured to lift the monolithic housing, a diaphragm formed of a flexible material and mated to the monolithic housing, a rigid duct mated the frame to form a pneumatic path between the monolithic housing and the rigid duct through the diaphragm, and cleaning extractors disposed in the interior cavity of the monolithic housing.

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.

A floor cleaner including a including a base, an upright portion, and a recovery tank. The recovery tank includes a baffle configured to separate liquid and air from a liquid-laden stream entering the recovery tank.

A rotary surface cleaning machine for cleaning floors, including both carpeted floors and uncarpeted hard floor surfaces including but not limited to wood, tile, linoleum and natural stone flooring. The rotary surface cleaning machine has a rotary surface cleaning tool mounted on a frame and coupled for high speed rotary motion relative to the frame. The rotary surface cleaning tool has a substantially circular operational surface that performs the cleaning operation. The rotary surface cleaning tool is driven by an on-board power plant to rotate at high speed. The rotary surface cleaning tool is coupled to a supply of pressurized hot liquid solution of cleaning fluid and a powerful vacuum suction source.

A carpet cleaning accessory device is provided. The carpet cleaning accessory device comprises an aperture stop configured to fit between an aperture frame and an aperture gate where the aperture stop has at least a first hole and a second hole. The device also includes a conduit having at least a first opening and a second opening, where the conduit is secured inside the aperture stop such that the first opening couples with the first hole and the second opening couples with the second hole. A curtain adapted to couple to the aperture frame and the aperture gate using a coupling assembly is also included to substantially block an opening between the aperture gate and the aperture frame.
