Abstract
A new vacuum cleaner that is adapted for use in a vehicle has a user-removable debris collection tank that has spaced recesses on the bottom that inhibit both fore-and-back movement of debris within the collection tank and side-to-side movement of debris within the collection tank. The recesses are located in opposed outer corners of the tank, and have lower surfaces that support the tank in a standing position. Raised sections divide each of the recesses into two corner recess sections and an offset recess section, and inhibit both fore-and-aft movement of debris within the recesses and side-to-side movement of debris within the recess sections. The offset recess section has tracks that curve in different directions from an intermediate position adjacent or near a side of the tank. The bottom of the tank is generally curved downwardly towards the sides of the tank.
