Comments about Smartpool Nitro� Wall Scrubber Robotic Pool Cleaner NC71:
I tried it three cycles in a row (9 hours) and the pool is still almost as dirty as before. It doesn`t suck up sand from the floor. I have to push it to another part of the pool manualy, because the first cycle it stayed in 1 area for 21/2 hours. When you take the `cleaner` out of the pool, a lot of dirt falls back into the pool.
If only I had known before, I would never have bought it. Now it`s to late. Returning this item would take another month or 2 (It was at Customs Belgium for 3 weeks) and a lot of money. Taxes in Belgium are €183.- ($240.-) so if I return it and get another one, I would have to pay that again.

I bought one a few weeks ago. I watched as it kicked dirt on the botton into suspension. Always leaves the pool looking dirtier than when I started. Supplier took it back and gave me a new one. Same problem. I'm asking for my money back.
