I've tried so many different types. First started with a Barracuda that would waste thru my filter, it didn't work great. Then I bought a battery operated vacuum that would waste into a bag and that hardly sucked up anything. I'm currently using just a roller connected to my hose that wastes into the filter. I'd love to get a great vacuum that wastes into it's own bag that actually works. Considered the vacuums powered by a hose but I see the bag doesn't catch much of the pollen and fine sediment. Any suggestions would be appreciated!
