Pool blaster spa vacuum

I recently purchased this vacuum for my small pool (7ft x 9ft). I’ve used it two or three times. I think it would work best for a smaller pool or hot tub/spa. My pool is prone to leaves and this works best to pick up sand/dirt/small debris. Itembis still in great working order. I will include the batteries (opened) that I used for it. Still lots of life left.
