Abstract: A direct port vacuum cleaning system comprises a vacuum cleaner housing including a vacuum generating unit having a blower within a blower housing, and a debris canister housing detachably directly connected to the blower housing providing a defined path for a flow of air through the system. The debris canister housing has an air input and outlet directing the flow of air along the defined path into the debris canister housing, out the canister air outlet, and directly into the blower housing when the canister air outlet is connected directly to the air inlet of the blower housing. The vacuum cleaner housing is shaped for disposition between the outer shell of a vehicle body and an inner surface panel inside a vehicle; or within the back cushion of a seat within the vehicle; or within a cabinet located between two laterally spaced, side-by-side seats in a vehicle.
