Abstract
The specification discloses a wet vacuum/extractor including an add-on liquid dispensing system. A liquid supply tank removably mounts on the vacuum and couples with the vacuum exhaust for momentarily pressurizing the tank to prime the liquid dispensing system. A remote pump is included at the wand handle and is powered by low voltage current from the vacuum.
