My old classic aqaubot has gotten stuck 2 of the last 3 times I used it. One time it got stuck on the pool light (of all things) and once on the built in steps of plaster pool. I have read all the info here and the websites on blue pearls. In both "stuck" situations, the aquabot hadn't left the water and couldn't remove itself in either direction it tried. So, even with the advances of the Blue Pearl, what might keep it from getting stuck the same way? Maybe the better brush?

My old pool rover plus had issues with being stuck in a pattern, but have to say that the jet drive was very good about not getting compleltely stuck in 1 place. Regardless of the company, do all belt driven robotics risk getting stuck the same way?
