SIMPLE, DESIGN - that 't break and doesn't require electricity. There are no unnecessary mechanisms that easily brake or clog or jam and the hose is flexible. This spa vacuum will last for years and years, as long as you don't use it for sword fighting or let your dog use it as a chew toy.CONSTANT CLEANING SUCTION - to easily suck up sand and other particles the filters don't get. This allows you to quickly and effectively clean your spa with minimal loss of water. Other spa vacuums require electricity or only work while you pull a handle.NO NEED TO DRAIN YOUR HOT TUB - now you can clean the debris from the bottom of your hot tub without having to drain the water. Use this spa in conjunction with regular chlorine and shock treatments to maintain crystal clear water.HOW TO USE - keep nozzle in the water, bend down so the drain is lower than the of the water, place hand over the bottom hole, suck hard for about one second, release hand from bottom hole, and start cleaning! You can rotate the nozzle by twisting the rigid pipe connected to the nozzleFOR SPAS, HOT TUBS, AND SMALL ABOVE-GROUND POOLS - not intended for large pools or for draining, that would take a very long time.Colour:As ShownMaterial:PlasticPackage Contents:1 * Spa vacuum cleaner
