I used a normal pool brush before, and always had the problem with the brush not sticking to the wall. I would normally have to use a lot of force to successfully brush a vertical section of pool wall. Then the brush finally broke. So I went to a local pool supply to get another brush and came across the Wall Whale brush. It’s unique because in addition to the brush, it has a fin, which creates a powerful force, that basically sticks the brush to the pool wall. It’s pretty effortless to use, and successfully cleans the area that I brush.
I have had it for a few months and love it.
