This innovative tool dispenses cleaning solution right from the mop handle. The easy-to-squeeze ergonomic trigger and no-slip tip evenly dispense liquid in three streams behind the mop frame. A 21-oz capacity can clean up to 850 square feet before it needs refilling. There is also a full-length view window for monitoring the fill level, with a large opening for manual refilling. Or use the Pulse Caddy for hands-free refilling. Includes a 58″ long handle plus an 18″ mop frame. Requires an 18″ microfiber wet pad, but can also work with 11″ and 24″ mp frames and pads. For best results use with quat or phenolic disinfectants, neutral floor cleaners and ceramic tile floor cleaners.
