A vacuum cleaner, which is a portable vacuum cleaner, including a tank body, a head portion disposed above the tank body, and a battery connection portion that is disposed at the head portion and is capable of connecting to a battery. A part of an upper end portion of the tank body has a bent shape or a curved shape, and the rest part of the upper end portion of the tank body has a shape neither bending inward nor curved inward. The vacuum cleaner may further include a battery connection portion disposed at the head portion and a brushless motor disposed at the head portion. The vacuum cleaner is easy to assemble, portable, convenient in checking the battery level, waterproof and has a good performance of drainage, high efficiency in dust vacuuming, small size and compact structure, light weight, and improved service period.

A floor cleaner including a recovery tank. The recovery tank includes a tank body having a lower end wall, an open upper end, and a sidewall that extend upwardly from the lower end wall. A cover that includes a suction air outlet in fluid communication with a vacuum source. An inlet duct extends upwardly from the lower end wall. The recover tank includes a shutoff float including a float body and a closure. The float body is configured to float on a surface of cleaning fluid and the closure is received in the suction air outlet to close the suction air outlet. The float body moves along the inlet duct as the float body floats on the surface of the cleaning fluid. The float body includes an aperture extending through the float body and the inlet duct extends through the aperture of the float body.

A portable hard surface cleaning appliance is provided, including a suction nozzle having a suction opening at which at least one squeegee lip is arranged, an electrical device having a suction turbine in flow connection with the suction nozzle for suctioning a liquid air mixture from the suction opening, an electric motor, an electronic control system, at least one rechargeable battery, a separating device arranged in the flow path between the suction nozzle and the suction turbine for separating liquid from the suctioned liquid air mixture, and a liquid tank for receiving the separated liquid. The hard surface cleaning appliance includes an inner housing arrangement and an outer housing arrangement, wherein the inner housing arrangement accommodates the separating device and the electrical device, and the outer housing arrangement surrounds the inner housing arrangement.

Described and shown is an article of manufacture, system and process for the collection and capture of a desired substance, either solid or liquid, such as debris or residue. The present invention is particularly useful for the cleanup of glue or other substance (e.g. excess caulking or silicone sealant) employed during fabrication or construction where one or more components are assembled and affixed together using a fluid adhesive or are sealed together, etc. Additionally, the present invention concerns a vacuum tool comprising a substance capture reservoir in communication with a substance collection conduit and attachable to a vacuum source for the collection and capture of various substances, both liquid and solid.

A surface cleaning apparatus has a dirt collection chamber that is external to a cyclone chamber. The dirt collection chamber has a sidewall having a first sidewall portion that extends outwardly away from the cyclone chamber sidewall and a second sidewall portion that extends from the first sidewall portion towards a distal end of the dirt collection chamber. The cyclone chamber has a dirt outlet that faces the cyclone chamber sidewall.

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 floor cleaner including a recovery tank in fluid communication with a vacuum source and a suction inlet. The recovery tank is configured to store cleaning fluid drawn through the suction inlet from a surface by the vacuum source. The recovery tank includes a tank body and a strainer. The tank body has a lower end wall and a sidewall that extends upwardly from the lower end wall and an inlet duct that extends upwardly from the lower end wall. The strainer is positioned inside the tank body, the strainer movable from a lowermost position to a removed position. The strainer includes a perforated body and an aperture through the body, the inlet duct extends through the aperture of the strainer, and the strainer engages an outer surface of the inlet duct retaining the strainer onto the inlet duct.

A surface cleaning apparatus such as an extractor has an upright section moveably mounted to a surface cleaning head. The upright section comprises a first stage liquid separator and a second stage cyclone separator, wherein the liquid collection container and the solid collection chamber are emptyable concurrently.
