A vacuum cleaner is described, and in particular a battery-powered vacuum cleaner including a rotatable brush. The vacuum cleaner has a suction head adapted to be moved across a surface to be cleaned, the suction head having a leading end and a trailing end, the suction head having: a rotatable brush, the rotatable brush being located in a brush chamber at the leading end of the suction head, the brush chamber having an opening through which a part of the rotatable brush projects, the opening and the rotatable brush spanning substantially the full width of the suction head; suction means adapted to create a flow of air into the suction head during use; a dirt-collection chamber; a filter located downstream of the dirt-collection chamber; a primary air flow duct connecting the brush chamber to the dirt-collection chamber and through which air can flow into the dirt collection chamber during use, a secondary air flow duct connected to the dirt-collection chamber and through which air can flow into the dirt collection chamber during use, the secondary air flow duct comprising a length of hose terminating in an inlet nozzle.

A sealing system (1) for sealing between an inner pipe and an outer pipe of a telescoping vacuum cleaner suction pipe, which ensures maximum possible sealing with simultaneously simple operator controllability of the vacuum cleaner suction pipe, has at least one annular base body (2) of a first material and an annular sealing body (3) of a second material on the base body (2).

A dust collector with convenient loading and unloading dust collecting barrel includes a base plate fixed on an outer periphery of a bottom of an air guide cylinder, an operation unit whose end is pivotally arranged on the base plate, linking members disposed on said operation unit and connected to a dust collecting barrel lid located under the air guide tube. Accordingly, when a user lifts up the operation unit, the linking members move the dust collecting barrel lid upwards. The upward movement separates the dust collecting barrel lid from the dust collecting barrel, so the dust collecting barrel is easily detached. The action of swinging the operation unit swings down allows the linking members to move the dust collecting barrel lid downwards, so the dust collecting barrel lid closes the dust collecting barrel. Therefore, the user loads and unloads the dust collecting barrel quickly and conveniently.

An apparatus for cleaning fan blades of a ceiling fan comprising an L-shaped telescoping member inserted into the distal end of an elongated shaft having a detachable concave tray. In various embodiments, the cleaning apparatus comprises water dispensing means including a hose, nozzle and/or water pump. A concave tray may be detachable. The fibrous material may be detachable.

A robot cleaner station includes a cleaner docking portion to which a robot cleaner is docked and including an suction port in communication with a dust collector of the robot cleaner when the robot clear is docked to the cleaner docking portion, a collector including a collection chamber in which dust sucked from the dust collector through the suction port is collected, and a station suction device configured to generate a suction force to suck the dust from the dust collector to the collection chamber, and a connector configured to connect the suction port to the collection chamber. The connector includes a guide portion in communication with the suction port, a suction tube provided in the collection chamber to allow the dust which is guided by the guide portion to be sucked to the collection chamber, and a connection hose configured to connect the guide portion to the suction tube.

A hose retractor valve for central vacuum cleaning systems that utilize retractable suction hoses that retract into a system vacuum tubing for storage. The hose retractor valve includes a vacuum assisted hose lock and seal assembly comprising a tapered cylinder and an elastomeric cylinder which restrain the vacuum hose from being drawn into the system vacuum tubing while in use, and seals around the hose outer diameter to prevent air from passing between the inside of the system vacuum tubing and exterior of the hose at the valve assembly. The hose lock and seal assembly is self-locking and vacuum assisted, while also permitting additional hose to be extracted by pulling on the hose.

Disclosed is a vacuum cleaner having an improved structure for preventing hair or foreign substances from being caught in a wheel. The vacuum cleaner includes a suction nozzle having a suction passage for cleaning a surface to be cleaned by a suction force and a wheel assembly accommodated in the suction nozzle and configured to be rotatable. The wheel assembly includes a wheel and a rotating shaft to rotatably support the wheel. The rotating shaft is inclined relative to a bottom surface of the suction nozzle.

A suction head for a vacuum cleaner or the like is described, said suction head comprising: a base plate with a base plate channel open towards a surface to be vacuumed, a suction channel in fluid communication with the base plate channel, main wheels for moving said suction head on the surface to be vacuumed, and a bracket for connecting said main wheels to said base plate, wherein said bracket is connected to said base plate in a rotatable manner so that said base plate is tiltable with respect to the main wheels.

A cleaner for collecting dust is provided. The cleaner includes a suction head, a dust collector having a first end mounted on the suction head and including a first dust collecting chamber, an extension member slidably mounted on the dust collector at the other end opposite to the first end of the dust collector, and a first dirt removing member disposed at one end of the extension member and having elasticity.

A dust collecting device with an extendible and flexible air tube including a housing, a cover, an air tube, a dust collecting head, a filter material and a gas guiding device. The cover is detachably disposed on the housing and has an accommodating groove. The air tube is positioned in the accommodating groove and extendible and flexible, the air tube is capable of being extended to outside the accommodating groove and retracted to be accommodated in the accommodating groove, and a bending angle and an extension direction of the air tube is changeable by flexibility. The dust collecting head is disposed at the air tube, and is positioned in the accommodating groove when the air tube is shortened to be accommodated in the accommodating groove. The filter material is disposed inside the housing and close to the cover. The gas guiding device is disposed inside the housing.
