The present invention is directed to ergonomic enhancing devices for moving portable cleaning equipment up and down steps and stairways. In the preferred embodiment of the present invention, the ergonomic enhancements consist of an upward extended handle and a stair-climbing wheel assembly introduced into the design of a portable cleaning equipment. The combination of an extended handle and a stair-climbing wheel assembly greatly reduces the effort required to move the equipment up and down steps and stairways.
