The jetvac allows you to easily clean the dirt and debris from your spa or small pool. It has a dual use design where you can use it with either a garden hose or with your pool or spa suction hose, no need for batteries. All dirt and debris is vacuumed into the unit's own reusable, easy to clean filter bag. Jetvac is light weight and can be hand held in the shallow areas or be attached to a pole for deeper parts of your spa or pool.
