Well just put the bot in the pool and it worked great. The pool was significantly cleaner after one 4hr run and I have been running the filter a lot lately. Looks like it covered the entire pool even the in pool steps. Ran up to the waterline with out any problems. No sticking on the ladder. Did have a problem with the main drain. I was sort of disappointed as I did not want to have to purchase a adapter. Other wise I was pleased. Recieved the bot in 4 days despite the advertised 7-10 shipping.
