Got the Aquabot T4 2 years ago for $1400! It worked well for 1 season, after that, it needed constant attention: the vacuum bag needs to be changed very frequently, even if the bag is not full, we changed the treads a year later, but the cord is the biggest hassle because it gets tangled up extremely easily, coiled on itself and prevents the vacuum to cover the area of the pool, defeating its purpose. It is impossible to uncoil it, the wires are very strong and once tangled, forget it. We are now looking for the best cleaner yet!
