A pool vacuum generally works. Generally, you'll want to check with who has supplied or installed your swimming pool. There would be a hose and an attachment that can hook directly to the filter system. This will recirculate the water through the filter, which should get rid of any fine particles causing a brown or murky look on the bottom of your pool.
Do you sell these pool vacuums?
We do have swimming pool vacuums listed here for review purpose or to purchase, or compare. However, we can't guarantee these vacuums will work with your pool. The best thing to do is to check with your pool supplier if they have a vacuum that you can utilize with your pool. Based on the manufacturer and model of the pool, the supplier may be able to find you a vacuum that works.
