The present invention relates to an autonomously operable vacuum cleaner that has a modular design. The vacuum cleaner in this respect comprises a cleaning head module as well as a separate canister module. The cleaning head module and the canister module are in this respect connected to one another via a hose so that dust sucked in via the cleaning head module can be conveyed into the canister module.

A hand vacuum cleaner with a finger grip area that is provided between a forward side of the handle and a rear side of the main body, and wherein the suction motor is positioned between the cyclone and the finger grip area and an axis that extends between the front of the cyclone and the handle extends through the suction motor.

A HEPA-qualified coating removal system, coating removal tool, and method is disclosed. The HEPA-qualified coating removal system comprises a HEPA-vacuum coupled to a coating removal tool via a vacuum line. A method of using the HEPA-qualified coating removal system includes, but is not limited to, the steps of the user putting on appropriate protective equipment, connecting the vacuum line of the HEPA-vacuum to an outlet of the coating removal tool, activating the HEPA-vacuum, using scraping motion of coating removal tool to strip a surface and the resulting loose debris being removed by suction force from the environment, deactivating the HEPA-vacuum, and disposing of the debris collected in the HEPA vacuum.

A handheld air purifier may include a suction body provided with a suction surface having a first and second frame, a fan to suction air, and a filter to filter suctioned air, a bending portion extending rearward from the suction body to bend upward, and a handle extending further from the bending portion and held by the user. The second frame may be provided behind the first frame and may include a protrusion that penetrates through the first frame to create a gap between the suction surface and a garment being treated to promote a free airflow through the handheld air purifier.

A vacuuming broom assembly includes a vacuum pack that is wearable on a user's back. The vacuum pack has an intake for urging air inwardly therein when the vacuum pack is turned on and a suction hose is fluidly coupled to the intake. A broom is provided that has a head and a handle. A suction manifold is coupled to the broom and the suction manifold has a pair of inlet ports and an exhaust port. The suction hose is fluidly coupled to the exhaust port such that the suction manifold is in fluid communication with the vacuum unit. Each of the inlet ports is aligned with the head of the broom for sucking up debris that is produced from sweeping. In this way the vacuum unit reduces airborne particles produced from sweeping.

A method of controlling a moving robot is provided. The method of controlling a moving robot includes the steps of: (a) performing a basic motion of the moving robot which moves on a rotating mop; (b) measuring the slip rate of the moving robot; and (c) controlling the travel of the moving robot.

A mobile cleaning robot can include a body, a drive wheel, and a plurality of skids. The drive wheel can be connected to the body and can be engageable with a floor surface of an environment. The drive wheel can be operable to move the mobile cleaning robot about an environment. The skids can be separate skids that can be connected to the body and can be engageable with the floor surface to support, together with the drive wheel, the mobile cleaning robot with respect to the floor surface.

A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.

A cleaner includes a body, a left spin-mop module and a right spin-mop module configured to perform mopping, and a water supply module configured to supply water to the left spin-mop module and the right spin-mop module. The water supply module includes a water tank to store water therein, a pump to pressurize the water in the water tank to move the water to the left spin-mop module and the right spin-mop module, a first supply pipe connecting the water tank and the pump, a common pipe connected to the pump, the common pump configured to guide movement of the pressurized water from the pump, a first branch pipe configured to guide a first portion of the water in the common pipe to the left spin-mop module, and a second branch pipe configured to guide a second portion of the water in the common pipe to the right spin-mop module.

A handheld extraction cleaner includes a unitary body provided with a carry handle, and further provided with a supply tank, a suction nozzle, a recovery tank, and a suction source, all of which are carried by the unitary body. In one aspect, the recovery tank is configured to optimize the usable volume within the tank and a user's view of the collected dirty liquid within the tank, among other functions. In another aspect the recovery tank has an auto-close feature that automatically seals an outlet of the tank when the recovery tank is mounted to a tank receiver of the unitary body. In yet another aspect, the extraction cleaner has an agitator that slides out from a side of the unitary body. In still another aspect, the suction nozzle includes a cleaning angle guide skid to orient the extraction cleaner at an optimal cleaning angle. In a further aspect, the supply tank is a non-removable part located at a rear of the unitary body.
