U2C1 housekeeping droids were manufactured by Publictechnic. The model had a bare humanoid frame cast from a blue hardened plastic, and had a vacuum arm made from black flexi-hose. One was equipped with a stiff wire brush to remove persistent stains and the other had an attachment for cleaning upholstery. Both arms connect to the storage bin located in its middle; this was emptied via a hinged panel at the back. The droids were usually employed as robotic janitors or night maids.
