Query: great pool bug

super easy pool bug. took 5 minutes out of the box to be in the pool and cleaning. had a minor issue with small rocks in the pool and the bug clogging up but we cleaned it out and it ran great. had some construction going on around the pool and it was able to clean out sand...sawdust and some left over spring pollen and it was clean in a few hours.
