ABSTRACT:
A wheel frame for supporting at least two wheels along the bottom surface of a vacuum inlet nozzle of the type commonly used for vacuuming concrete floors of shops and other areas which have cement or wooden floors. The wheel frame is rectangular and has preferably two wheels held by the frame. The frame fits over the conventional vacuum nozzle and snaps over the flange at the bottom of the vacuum nozzle. The wheels are positioned so that they are near the back of the nozzle so that the front edge of the nozzle can be lifted by tilting the nozzle toward the back. This greatly facilitates the vacuuming up of leaves and other larger objects which do not fit under the front edge of the conventional vacuum nozzle.
