ABSTRACT:
A hand-held vacuum cleaner is disclosed including first and second air intake chambers to accommodate cooling air intake to the vacuum cleaner motor, and an exhaust chamber to accommodate exhausted cooling air from the motor. The motor has a cooling fan which draws cooling air in from both ends of the motor and exhausts it from a middle portion thereof. First and second peripheral baffle walls in a motor mount portion of the vacuum cleaner housing extend towards contiguous engagement with the motor to define air intake and exhaust chambers. A motor mounting plate is fastened to the motor and is secured in the housing by a wedging and binding reception in a slot within the housing.
