Keeping a pool clean that has a filter cartridge pump filtration is very difficult. In the past there has not been a vacuum that can attach in-line to the filtration as it would on a larger pool but that has all changed with his pool VAC. This vacuum attaches directly into your pools inline filtration system! This vacuum is a must for cleaning the bottom of your inflatable pool. Normally any small particles just pass through the filter bag on the Venturi Vacs that you use with a hosepipe but with this Vac these particles are passed along a flexible hose and caught in your filter just like a full size pool! This Vac fits directly into any pool's filtration system and has adapters to fit most pools from 8ft Easy Set Pools to a 24ft metal frame pool. This amazing Swimming Pool Vac has an internal Filter to ensure that larger debris does not get to the filter to block it up. 3 different sized adapters means This vacuum will fit most Intex, Bestway, and most others. THIS DOES NOT WORK ON SUMMER ESCAPES POOLS SOLD AT KMART. This can be used with pumps of 1000gph or 1500gph or 2500gph.
