I've never used a pool-robot and am thinking of getting one. Our pool is very clean and just gets a few bugs, little sand and minor stuff that falls to the bottom of the pool. I usually just use a net to skim the bottom and use the vacuum every couple weeks. I guess what I'm looking for is a automatic floor robot that filters on it's own so that I can drop it in the pool and leave it. I was looking at the Aquabot but I'm just not sure and was hoping someone could help steer me in the right direction. Pool is vinyl and is a sport pool shape, deep in the middle.
