Abstract
This is concerned with a solid-state electronic brush speed sensing control for sensing the rotational speed of the brush in a vacuum cleaner, either of the canister or upright type, so that as the brush slows down or stops due to being jammed or partially jammed by a foreign object, such as a sock or the like, the drive motor will be disconnected from its source of power thereby protecting the brush, the motor, the belts, etc.
