That is helpful Hzz.

One issue I also found annoying about my Aquabot (regular model) was that the tracks would slip out of their place, which would then stretch them even more before you noticed to push them back. With more stretching, then they would be even more likely to do it again, and the tracks would get looser all the time and more problematic, long before they ever should have worn out. I had the old model with the floats on it compared to the new floating cable, which were really bad for being eaten and then damaging the aquabot if you weren't there.

One thing good about pool rover plus was it did have the floating cord they all have now, but it also didn't have any tracks to eat the cord or to stretch or break. As posted by me elsewhere, the problem was with coverage on an oval pool. If I thought it would cover my new pool, which is more rectangular in shape (but larger and with inlet for wide set of steps that might be a problem), I might get it again. My pool rover plus never broke, but I had it a short time before washed away in Katrina. On an oval pool, it was bad. No matter how long I fiddled with the cycles, it always ended up cyling in same spot. It relies on somethign like a "y-turn," which relies upon the pool rover goign straight in 1 direction, and turning in the other. In oval pool (with stright sides), the pool wall curve would make it also curve, throwing it off, and it would do same exact path over and over once it got to the deep end.
