Abstract
This is concerned with a sensing control for a vacuum cleaner to sense the speed of the beater brush so that when it becomes clogged or jammed and tends to slow down, the control will automatically disconnect all power from the drive motor to thereby protect both the motor and any drive belts that are used. Some aspects are usable with either a canister or an upright vacuum cleaner and some are specifically concerned with an upright unit.
