Bests & Worsts Reviews from Amazon

Update: I sent it back! Yes, after a good review it went bad. What happened was the next day it would bump into the wall and just sit there. The flapper on top just wasn't smooth enough to flip over. I had high hopes. It vacuumed well, battery life about a good 30 min. Too bad. Wasn't sure if battery power was going to do it. I'm an engineer so I know batteries. After I charged it I dropped in the water. I have a 18' round above ground pool. Was running great then after 20 min., it started slowing down. So I'm thinking the batteries weren't lasting as long as they stated. I pulled it out and opened it up and it was filled of debris. What was happening is the algae had covered the screen restricting water flow, that's how it moves. I cleaned the screen and it ran great again. Battery effectively runs about 50 min. Not a big deal, that's all my size pool needs.
