A wand and hose assembly for a vacuum cleaner includes a suction wand fluidly connected to the end of a suction hose by a duct and the duct incorporates an articulating joint for allowing articulated movement of the suction wand relative to the end of the suction hose. The wand and the duct are arranged for telescopic sliding movement relative to one another, and the articulating joint is moveable into a position in which the wand can slide telescopically through the duct for retraction into the suction hose.

A ball swivel of the configuration typically utilized for pool cleaners includes male and female portions featuring an interposed stopper to reduce friction and prevent the male and female portions from binding under load, while improving sealing and continuing to allow rotational and pivotal motion.

A vacuum system for vacuuming is disclosed. The vacuum system includes a baseboard cleaning attachment, a floor cleaning attachment, and a hose attachment. Each of the attachments is selectively mounted to a hose of the vacuum system for vacuuming floors, baseboards and tight spaces. The baseboard cleaning attachment includes a brush head having a right-angled portion, and a curved portion. The brush head includes a neck to mount the brush head to the hose. The right-angled portion is aligned with the baseboard and is used to vacuum. The floor cleaning attachment includes an elongated tube, and an under furniture handle mounted to the elongated tube. The elongated tube includes a beater head with a beater. The elongated tube is mounted to the hose, and the under furniture handle is used vacuum under furniture. The hose attachment is in an S-shape for tight spaces.

A central vacuum cleaning system includes a locking collar mounted at various locations in a structure or RV and connected to the inlet end of a vacuum conduit. A section of hose is slidably mounted within the conduit and extends therefrom for cleaning an adjacent area. A pair of O-rings within the collar frictionally retains a handle mounted on the end of the hose in a stored position when the hose is in a retracted position and provides an air seal between the handle and vacuum supply conduit. A locking mechanism mounted on the collar automatically locks the hose in a selected extended position when manually pulled from the collar by a locking finger engaging an adjacent section of the hose. An electric switch on the collar enables a user to actuate the vacuum supply source. A mounting bracket enables the collar to be mounted at various locations in the structure and a ring formed on the collar enables the collar to be rotated to a desired position on the mounting bracket.

A suction head for a vacuum cleaner comprising a base plate with a base plate channel open towards a surface to be vacuumed and a suction channel in fluid communication with the base plate channel is described. Said suction channel comprises an inner tube and an outer tube, wherein the inner tube is fixed to the base plate channel and the outer tube is rotatable telescopically with respect to the inner tube.

A surface cleaning apparatus, wherein the suction motor is operable using current supplied from an energy storage member when the power cord is removed and operable using current supplied from an external source when the power cord is in electrical communication with the suction motor.

An autonomous vacuum cleaner includes an outer housing and a separator assembly that is removably received by the autonomous vacuum cleaner. A portion of the separator assembly defines a portion of at least two walls of the outer housing.

Disclosed are related to a dust collecting apparatus, a cleaning apparatus, and a method of controlling the cleaning apparatus. The dust collecting apparatus may comprises a dust collecting space configured to collect impurities and a variable body formed to surround the dust collecting space and having one of transparency, shape and color changed by selectively transmitting or reflecting light in response to applied electric power.

A cleaning apparatus for use in explosive atmospheres is disclosed, the cleaning apparatus being configured to conduct to earth any electrostatic charges generated in the components of the apparatus thereby preventing electrostatic discharge. The apparatus comprises a flexible hose member comprised of an electrically conductive material and having first and second open ends, the hose member being suitable for attachment at its first end to a port of an associated suction unit to mechanically and electrically couple said hose thereto; and a substantially rigid tubular pole member comprised of an electrically conductive material and having first and second open ends, said pole member being mechanically and electrically coupled at said first end to the second end of said hose member.
