Note: This one comes with 3 weights. They are removable and you can also move them to different positions for the best configuration for your application.I asked Amazon Answers about using this on a cement pool. I got some good responses. My pool is only about 11,000 gallons and I wanted a device that would vacuum and brush at the same time. When I received this the box said for vinyl/fiberglass, but when I asked, others on Amazon Answers said they had used it successfully on a cement pool.I tried it and it worked well. I had some algae stains on the Marcite, as well as the rest of the dirt in pools. This cleaned it all up quite well.Here is where there is a caution! One needs to reduce the suction on the hose so it can move on the surface. I left the weights in. Here is the tricky part and it just takes practice. You can pull it to you OK, but you definitely can not push it away on a cement pool. It got so it was relatively easy for me to do. On the sides, I just pushed it straight down.I love this unit, it's sturdy, well built, and to me the brushes look rugged. I had no problems with it at all on my Marcite pool.This all said, if you don't want to practice with this unit to get the hang of using it on a cement pool, it's probably not for you. I liked it because I could get really stubborn dirt off the Marcite and I was able to vacuum and brush at the same time. Whatever, you do need to reduce the suction on the hose, otherwise, you'll never get it to move on a Marcite pool, for example.For me, it's a miracle unit and it is absolutely well built and not cheap junk like some of the lower cost units. It was worth every penny for me.
