Vacuum or drain your spa in minutes with the HeatWave Spa Drain and Vacuum. Designed with self-priming, siphon technology, this spa vacuum doesn’t rely on electricity, batteries, or moving parts. Simply insert the suction tube into your spa, shake the tube, and watch it easily remove dirt and debris from your hot tub or jacuzzi. A 12-foot-long discharge hose allows you to direct water away from the spa area if you are draining instead of cleaning. 1-year limited warranty.
