I have been using a lil shark since I got my pool last summer. It does o.k. but is not the most convienient process in the world and often needs to be bumped to get going again. Anyway, I am ready to upgrade to a better and more convienient vacumm, especially since I have lots of neighboring trees and seem to need to vacumm twice a week. Having one that doesnt tie into the pools sand filter would be a plus too. I have read quite a few posts on the forum about the Pool Rover Jr. and it seems to be well liked. Are there any other automatics that you guys would suggest? Seems like I did see some posts complaining about the rover jr. not picking up all the sand on the bottom of pools? I don't mind spending a little extra money if I can get a really good vacuum and make life that much easier with pool cleaning.
