Performs as advertised
I was looking for a cleaner that would pick up fine particles. This was the only one that listed 2-5 microns filtration. I have only used it 6 times, and it fits the bill. It has 2 sets of filters: fine and ultra fine. Easy to use: drop in pool, plug in, push button, put enough cord in pool, come back 2 1/2 hours later. Pull out of pool, hose off filters and cleaner and store securely out of sight...and admire your clean pool. Have not seen a cleaner climb to the surface and clean down the tile scum wall. Repeat process every 3 days. Only possible drawback is that closest repair facility is 400 miles away.

Leaves my pool sparkling.
This cleaner is amazing. My pool has not been this clean since we first opened it. I use the ultra fine filter most of time and it works great. It does not climb my pool walls consistently, but no cleaner has yet. It is high priced, but it appears to be worth it.

Has a tendency to get stuck on the main drain. There is a work around. Other than that the machine is a pleasure.
