Got the Water Tech Xtreme Multi Layer Filter Bag for my Water Tech Volt FX-8Li Vacuum and have used it 3 times. Unfortunately it’s to good at collecting debris. The issue I have is when it comes to cleaning the bag. The larger pieces can be flushed off and away from the filter bag relatively easy with a hose. The issue comes in with removing the finer/smaller material which collects in the fine multi layer material. It does not flush out easily and has built up after the 2nd & 3rd use. Also when trying to manually rinse/rub/pull the dirt away from the bag material, the cotton like material would come off also causing it to be thiner in areas. As the debris built up during vacuuming the suction would become less powerful and would have to go over areas multiple times to remove debris. If Water Tech could develop a bag that was mid way between their original bag and the multi layer bag it would be better for the consumer.
