The Automatic Dog Washer is a machine featured in "Donald's Dog Laundry".
The purpose of the machine is to give whomever is in the tub a bath. There are several ways that ths contraption goes about it's duties, such as scrubbing and showering whoever is in the tub, as well as drying them off with a towel.
