Does the job!
I admit to being skeptical that this vacuum, that looks more like a toy, could do credible work. I was wrong. After some mixups about shipping from Water Tech, Home Depot straightened out the order and the Catfish arrived. I use it on a large reflecting pool in a public park three times a week. This pool sits under oak trees and picks up all sorts of debris. While we skim the leaf drop with traditional skimming poles, we use the Catfish to remove sand, sediment and muck. It takes me a little over a half hour to suck up almost all the debris - maybe to 90% or better. When done, the pool shines like a jewel in the sun. The design really works and the battery last a long time and charges in an hour or so. I'd recommend the product as useful - also recommend the purchase of a sand and silt bag which has a finer mesh. The bags are overpriced, but for the use of this machine, what would we expect?

      This pool blaster does not seem quite as substantial as the one I needed to replace, but I used the older one for 10+ years so have no complaints. I love the new bag, as it catches fine silt, which the older bag did not.
