The Paradise Spa Vac is one of the fastest and most efficient hot tub cleaners available on the market. This small yet powerful cleaner is ready to use right out of the package with no charging or batteries required. The spa vac uses suction to pull dirt and debris into the clear chamber where it captures the dirt and allows clean water to drain back into the hot tub. Simply place your thumb over the hole at the end of the pole, put your spa vac on or around dirt, let go and let the suction capture that dirt. Once the suction stops, pull the spa vac out, twist the removable head off and you’ll see the dirt you just collected.
