The Aquobot T2 was a great machine for the first year. Since then I have sent it back for repairs at least twice per year at a cost on average of $350.00 per repair.
I am very disappointed with the durability. When I spend $1200 for a pool cleaner I expect it to last for several years. I have sent it for repairs and gotten it back and it lasted only 3 days before it needed another $350 repair. I am switching to something I can count on.
