A cleaning apparatus having a housing, a motor, a transmission, an attachment stud, and a cleaning attachment removably connected to the stud. The stud has a leading section with a general triangular block shape and three generally triangular shaped cantilevered tips. The stud is received through a generally triangular shaped aperture in the cleaning attachment. The apparatus can reverse the normal rotation direction of the stud to allow the cleaning attachment to quickly disconnect from the stud without a user having to hold the cleaning attachment.
