ABSTRACT:
A janitorial cart is small, and narrow enough for use indoors, and will pass through conventional-width doorways. The cart is electrically powered, and the batteries are mounted very low so the lower center of gravity will stabilize the cart. The steering mechanism utilizes a single, rear wheel that can be turned about 90.degree. in each direction to give the cart a small turning radius. Accessories can be mounted on the front and/or the rear of the cart. The preferred accessory for the front is a dust mop apparatus for dust mopping large floor areas, but it is contemplated that brushes, burnishers and carpet sweepers will also be used. The rear accessory is contemplated to be a container for materials or supplies.
