A long handled electrical device with a rotating brush at the end that someone could use to clean a bathtub. No more bending over or getting down on hands and knees. Could be similiar to the idea of an electric toothbrush but of course very large with a good sturdy easy-to-hold handle. A person should be able to stand while using this product. It should have brushes that clean the bottom of the tub as well as the sides.
