One of the biggest concerns people have when purchasing a pool is the maintenance cost. When you choose a pool by Hydropool, you get self-cleaning technology that sucks debris from the floor of the swim spa and a collection skimmer that sucks up all debris floating on the surface of the water. To enhance this further, these swim spas have a self-cleaning mode that circulated thousands of gallons of water every few hours down to the 5-micron level so you can be sure that the water is always safe for friends and family to use.
