Hi,
I am in the market for a robotic vac for my free form IG vinyl pool, 18 x 36, 8 foot deep end.

I am looking for something that climbs the walls and has good filtration and can grab stuff down to fine algae and pollen. I normally don't get a heavy load of leaves, mostly just fine debris. I'd like something that can take the place of periodic brushing. I don't need it to have the remote control either.

I've been looking at the various versions of Aquabot, but it is not real clear on the differences. For example Aquabot Xtreme vs. Supreme. Also looked at the Hayward Shark Vac, the Tiger Shark, Aqua Clean and Dolphin. Some of the models have a filter element, some have a bag. Is the bag or filter element better? After reading some info on line it looks like the Dolphin is troublesome even though the guy at Leslies swears by them. I'd like to stay under $1000, which seems very possible.

Does anyone have any experiences, good or bad on Robotic vacs that they could share?

Thanks
Andy
