A filter is carried by the cover and includes an upstream surface and a downstream surface through which working air passes. When a user of the vacuum cleaner opens the cover, the upstream surface of the filter can be seen by the user.

An extraction cleaner includes a supply tank, a recovery tank, a pump, a suction source, a base configured to support the suction source and the pump, an external hose, and a hose attachment assembly. The hose attachment assembly has a suction conduit extending from a suction inlet connected to the proximal end of the hose to a suction outlet in fluid communication with the recovery tank. The suction conduit is removable from the base with the hose. The hose attachment assembly also has a fluid coupling which is removable with the suction conduit. The fluid coupling extends from a coupling inlet in fluid communication with the pump to a coupling outlet coupled to a supply tube having one or more portions carried within the suction conduit. The proximal end of the hose is at least partially nested adjacent the base when the suction conduit is coupled to the base.

A suction apparatus is provided including a suction unit for creating a suction flow, at least one filter and a filter cleaning device, wherein the filter cleaning device includes at least one valve having a closing body and a counter device, and wherein in an open position of the valve the filter has a filter cleaning flow applied thereto and wherein in a closed position of the valve the filter cleaning flow is or becomes inactive, wherein the closing body has a first contact region and a second contact region, wherein, in the closed position of the valve, both the first contact region and the second contact region are in contact against the counter device, and wherein in the open position of the valve, a flushing air flow flows past both the first contact region and the second contact region to the filter.

A device, attachments, and method for grooming or cleaning the fur of an animal. The device includes a main unit, a steam delivery system operatively engaged with the main unit, and a liquid delivery system operatively engaged with the main unit. The steam delivery system is operable to selectively deliver a quantity of steam to the animal's fur and the liquid delivery system is operable to selectively deliver a volume of liquid to the animal's fur. The steam delivery system and liquid delivery system are selectively independently activated to perform a grooming or cleaning task with the device. One or more attachments are connectable with the main unit via a hose. Some of the attachments include a plurality of tines that extend outwardly in the direction of movement of the attachment along the animal's body and capture and lift hairs for improved application of liquid, shampoo, or air thereto.

A invention relates to a filter device for a vacuum cleaner having a turbine device and a motor for generating a first main air stream and/or a second main air stream through a collecting tank of the vacuum cleaner, wherein the vacuum cleaner includes two chambers and filter elements of the filter device are dedusted by an abrupt change in position of a pressure shock element in the chambers. Since, when one of the two chambers is being dedusted, the suction operation of the vacuum cleaner can be maintained through the other chamber, the filter dedusting can advantageously take place during continued suction operation of the vacuum cleaner. A method for dedusting a filter device in a vacuum cleaner, wherein, as a result of a valve being actuated, an air volume is driven out of one of the two chambers. As a result of this change in pressure, the pressure shock element is advantageously made to change position, and this can result in a backflushing pulse and mechanical shaking of the filter element, and dedusting of the filter device.

A portable surface cleaning apparatus for a floor surface includes a main housing assembly adapted to be hand carried by a user, the main housing assembly carrying a fluid delivery system adapted for storing cleaning fluid and delivering the cleaning fluid to the surface to be cleaned, and a fluid recovery system adapted for removing the cleaning fluid and debris from the surface to be cleaned and storing the cleaning fluid and debris that was recovered, the main housing assembly comprising a base housing, a supply tank received on the main housing assembly, a recovery tank received on the main housing assembly separately from the supply tank.

The present invention relates to a multi-functional wet vacuum cleaner that is mounted on a waste oil storage drum to absorb, collect, and remove waste cutting oil of machine tools, hydraulic oil residue of hydraulic devices, and post oil work residue generated during the production of metal products such as bolts, screws, nails, and the like. Also, the cleaner exhibits the ability to clean large volumes of waste. The multi-functional wet vacuum cleaner is characterized by comprising a cover unit to which a suction motor is mounted and a body unit which has an accommodation space. The body unit includes: a suction pipe connection part formed at the upper end of one side of the accommodation space; an opening formed on the bottom surface of the accommodation space; a guide pipe extending a certain length downward from the circumference of the opening; and a connection pipe installed such that one end is connected to the suction pipe connection part inside the accommodation space and the other end passes through the opening and protrudes further than an end portion of the bottom surface of the guide pipe, the connection pipe having a gap to allow air to flow into the opening.

A surface cleaning apparatus has a cyclone and a dirt collection chamber wherein the dirt collection chamber has a dirt collection chamber portion which is located axially spaced from the cyclone chamber and the dirt collection chamber portion has a transverse section in a plane transverse to the longitudinal axis of the cyclone that is annular.

A filter device for a vacuum cleaner. The filter device has two chambers, of which in each case at least one participates in suction operation of the vacuum cleaner, while a filter element of the other chamber can be dedusted. As a result, while one filter element is being dedusted, suction operation can be maintained through the other chamber of the vacuum cleaner. This advantage is allowed by an elastic membrane, which can change shape and/or move when the chamber to be dedusted is ventilated. The ventilation is effected by a pressure equalizing stream which can pass through a ventilation channel and a ventilation opening into the chamber to be dedusted. As a result of the movement and/or change in shape of the elastic membrane, a dedusting pulse is applied to the filter element, which can ensure, for example, that a solid filter cake is detached and drops into the dust collecting tank of the vacuum cleaner. A method for dedusting a filter device in a vacuum cleaner is also provided.
