Got pets that shed? You probably have at least one of those pet hair removing rollers with the split replaceable sticky roller. Roll it over your clothing and it picks up the hair.

The success of the Audio Desk Systems’ ultrasonic record cleaning machine made it inevitable that others would follow. A few have since been marketed that use existing technology and hardware such as Bob Ratcliff’s V-8, a stainless steel vat that can clean but not dry eight records simultaneously. It uses available hardware adapted by Mr. Ratcliff along with his motor driven rotating spit-like contrivance.
