Query: Do not waste your money

I just bought this pool vac to work in conjunction with my suction pool vac but returned it after 1 day. Living in CT with a lot of trees around my pool, there is always a lot of dirt on the bottom of the pool. First, I vacuumed half of 1 stair and the filter bag was already full and had to be cleaned out (so imagine how long it would take to clean a larger area). Second, most of the dirt came right back out the sides. Not sure if the optional micro filter bag would work better, but it would still fill up extremely fast and need to be cleaned constantly.
