  • On-board vehicle vacuum cleaner
    Patent number: 7152272
    Abstract: A vacuum cleaning system for a vehicle includes a console (12), which may be centrally positioned between the front seats (16) of the vehicle. A canister (10), in the form of a drawer to the console, is selectively removed, when vacuuming is to be commenced, and a flexible hose (96) unclamped from a side compartment (112) of the canister. The canister, with the hose attached, is carried by a handle strap (58) to a part of the car to be cleaned. A motor fan assembly (70) within the canister is powered from the vehicle's battery by means of a power cord (84) to draw dirt into a dirt cup (90) in the canister. Entrained air passes from the dirt cup through a filter (94) and is directed by the fan to an exhaust outlet (82) in the canister.
