DISPOSABLE. ezPOOLBag does not require washing and cleaning. When the bag is full, just throw it in the garbage. No more washing the dirty bags - no more mess. * UNIVERSAL. ezPOOLBag fits most of the automatic pool cleaners and pool cleaning robots. * EFFECTIVE. ezPOOLBag provides the same 2 microns filtration rate as the original cloth bag, but because it is much lighter, your automatic pool cleaner will climb the walls much longer. * GREEN. ezPOOLBag is made out of biodegradable, environmental friendly material. * AFFORDABLE. ezPOOLBag costs just a fraction of the original cloth filter bag.
