Had one for two weeks and am really disappointed..When its moving it does a good job of sucking up fine sand/dirt however it only works for a short time and then just stops moving..Ive tried different lenghts for the hose as well as changing the settings and still the same.It will just stop cold at different locations for no appatrent reason. I have a 24x52 AG.. basically wasted 140$ as the thing is useless..Looking at a Rover Jr or a Polaris now.
