Abstract
A wheel set attachment is used in combination with floor maintenance equipment, such as buffers, sanders, grinders, cleaners, etc. (“buffer”), which are typically equipped with small diameter wheels which make transport difficult. The wheel set attachment is conducive for conveying the device up flights of stairs, over obstacles, or conveying the device any appreciable distance. The wheel set attachment of the present invention easily attaches to the buffer without the need for tools and is quickly removed. Once installed, the wheel set attachment is stable and provides a pair of wheels which function as though integral to the buffer.
