摘要： A hand-held vacuum cleaner includes a housing, a source of vacuum, a hose removably connected to an intake section of the housing, a rotatably driven brush located at the intake section, and a system to automatically stop the brush from being driven when the hose is disconnected from the intake section. The hose is located on an exterior of the housing and connects the intake section to the source of vacuum. The hose is flexible and expandable with a relatively compact, free-standing, curved shape when connected between the intake section and the source of vacuum, but can be expanded in general accordion-like fashion when the hose is removed from the intake section to expand to about four times its compact length. The system to automatically stop the brush can also automatically reengage driving of the brush when the hose is reconnected to the intake section.

摘要： A vacuum cleaner with a housing, a source of vacuum, and an air chamber located in the housing and connected to the source of vacuum. The housing includes a bottom member, a top member and a handle contacting and extending from a top surface of the top member. The handle is separately connected to the bottom member such that the handle is supported by both the top and bottom members. The air chamber is located in the housing between the top and bottom members with an inlet aperture and an exhaust aperture located at the exterior of the housing. The air chamber is comprised of two half sections that combine to form an inlet conduit, an outlet conduit, and an impeller chamber. An impeller of the source of vacuum is located in the impeller chamber. The source of vacuum has a motor with a first end connected to the impeller and a second end forming a drive shaft to drive a belt connected to a rotatable brush assembly.
