The Leaf and Debris pool cover is made from fine mesh woven polypropylene or polyethylene fabric (hence why they are also called mesh covers).
The mesh allows rain water to pass through the cover while leaving the leaves, debris, bugs etc. on the outside. Because the leaves are kept from contact with surface water, they are easily blown off by any wind – or by a little manual assistance from a broom or leaf-blower.
Leaf and debris pool covers are lightweight (usually weighing not more than 10kg for a standard size pool), don’t require a roller, and can usually be fitted by one person. That said, they do take considerably longer to fit than a solar pool cover or thermal blanket – either of which takes less than a minute with a roller.
Leaf and debris pool covers are available and suitable for both in-ground pools and above ground pools.
