The battery power option is useless, wont even last 5 seconds on a full charged battery. It cant even pull water up the tube on 120 volt power, if you position the vacuum below the water it will pull water but only then and the other think is that When I spill a bucket or have sawdust to clean up, or even want to hook it up to a machine that spews the dust, it works great. But pick up anything bigger than fine dust? No. I spill a soda in the car, it will pick it up ok, but it isn’t a rug doctor or a heavy shop vac. Catch a puddle of light fluid, Biggest waste of money and space, the only positive note to add is that the shell is semi durable from the half a dozen times I have thrown it in frustation from its lack of suction.
