A central vacuum cleaning system includes an inlet valve 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 from the inlet valve for cleaning an adjacent area. A pair of seals within the inlet valve retains a nozzle 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 one embodiment of the inlet valves automatically locks the hose in a selected extended position when manually pulled from the inlet valve. A mounting bracket enables the inlet valve to be mounted at various locations in the structure and a pair of seals enables the inlet valve to be open to the ambient atmosphere.

A boom hose apparatus for a material collection vehicle includes a telescoping boom assembly and a hose assembly supported by the boom assembly. The boom assembly includes a plurality of telescoping conduits. A flexible hose is received through the telescoping conduits and can slidably extend from, or retract into, the conduits independently from the telescoping of the conduits.

A vacuum cleaner includes an air treatment or debris removable assembly with a multi-layer filtration stage. The multi-layer filtration stage can include an outer mesh screen, a louvered exhaust grill, and a multi-layer filter. Optionally, an inner perforated exhaust grill is also provided. The debris removable assembly can further include a cyclonic filtration stage.

A suction nozzle for a vacuum cleaner includes a suction chamber; an outlet duct; an underside for engaging a surface to be cleaned; a main suction opening in the underside, which opens into the suction chamber; an auxiliary suction path which opens into the suction chamber; and a bleed path in fluid communication with the outlet duct. The suction nozzle further includes a valve mechanism arranged to open and close the auxiliary suction path and the bleed path, the valve mechanism being movable between a first configuration in which the auxiliary suction path is closed and the bleed path is open, a second configuration in which the auxiliary suction path is open and the bleed path is closed, and a third configuration in which both the auxiliary suction path and the bleed path are closed.

The present invention relates to a solar-powered vacuum device primarily comprised of a telescopic first end that can receive at least one attachment, a removable canister, and at least one solar panel that powers at least one battery. A vacuum motor of the device can be powered by the battery, such that the vacuum can be used in any environment. The device is also comprised of at least one shoulder strap that allows the device to be used hands-free. In addition, the body of the device is primarily comprised of at least one light source that illuminates the area around the vacuum.

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 vacuum cleaner includes an air treatment or debris removable assembly with a multi-layer filtration stage. The multi-layer filtration stage can include an outer mesh screen, a louvered exhaust grill, and a multi-layer filter. Optionally, an inner perforated exhaust grill is also provided. The debris removable assembly can further include a cyclonic filtration stage.

A vacuum dusting attachment including a semi-flexible, elongated, thin, flat cleaning portion for tight spaces having multiple dust collecting chambers and aperture openings for equalizing and maximizing vacuum suction, light elements for improving visual efficiency, side edge brushes for loosening dust and increased dust capture, and a detachable, microfiber mesh cover for the cleaning portion for dust capture and retention; and a connected swivel handle portion including an ergonomically designed cushioned hand portion with soft raised ridges and bumps for non-slippage. An additional independent accordion hose extension vacuum attachment for use with aforesaid dusting attachment or other devices is provided, manufactured to withstand vacuum suction so as to retain desired lengths and bends to reach distant target areas, increasing flexibility when handling an attached dusting attachment, while collapsing for less space, and including a grip disk at one end, and an ergonomic handle on an opposite end, both for handling while in the act of extending, collapsing, and bending.

A boom hose apparatus for a material collection vehicle includes a telescoping boom assembly and a hose assembly supported by the boom assembly. The boom assembly includes a plurality of telescoping conduits. A flexible hose is received through the telescoping conduits and can slidably extend from, or retract into, the conduits independently from the telescoping of the conduits.

A vacuum cleaner comprises a cleaner main body configured to generate suction power; a suction unit configured to suck up dust and foreign substances by the suction power; a connection pipe configured to transfer the sucked dust and foreign substances; a connection unit comprising a connection pipe accommodator configured to accommodate an end portion of the connection pipe, a separation controller configured to separate the accommodated end portion of the connection pipe from the connection pipe accommodator, and a space configured to place the separation controller therein; and a power cable configured to supply electric power from the cleaner main body to the suction unit, and disposed to pass through the space in which the separation controller of the connection unit is provided.
