Robelle 20 x 40 ft Economy Winter Pool Cover — Navy/Black solid polyethylene, 8-year warranty

The Robelle 20 x 40 ft Economy Winter Pool Cover is a solid polyethylene winter cover designed to protect inground pools through the off-season while floating on the water and sealing out debris.

This Robelle cover combines a navy-blue topside with a black underside, a 7 x 7 woven scrim and a 2.2 oz/yd2 polyethylene film to deliver dependable winter protection for a standard 20 x 40 ft inground pool. The cover includes a five-foot factory overlap (making the overall panel 25 x 45 ft) and perimeter loops for vinyl water weights (sold separately) to secure the cover in place. Backed by Robelle’s eight-year warranty and more than five decades of cover-making experience, it’s built to resist snow, ice and seasonal grime while remaining affordable.

How durable is this Robelle winter cover compared with basic pool covers?

The Economy cover is made from a woven polyethylene scrim (7 x 7) at 2.2 oz per square yard — heavier than many bargain covers — and is constructed roughly 10% heavier than industry standard for this line. That combination of scrim and material weight improves tear resistance and helps the sheet hold up over multiple winters.

• 7 x 7 scrim weave increases tensile strength and tear resistance.
• 2.2 oz/yd2 polyethylene balances durability and affordability.
• 10% heavier construction than similar economy covers for added longevity.
• Eight-year limited warranty from Robelle for manufacturer defects.

How do I install the cover and secure it for winter weather?

Robelle recommends using vinyl water weights placed in the sewn-in perimeter loops to install and stabilize the cover; no other fastening method is advised. The cover should float loosely on the water with the supplied overlap draped over the pool edge, and any excess should be folded under the water weights to avoid damage from wind or deck abrasion.

• Use only vinyl water weights (sold separately) threaded through sewn loops.
• Five-foot overlap (cover measures 25 x 45 ft inclusive of overlap) simplifies fitting.
• Float cover loosely; choose a larger size if steps or seats protrude into the pool.
• Pad exposed edges where cover touches corners or decking to prevent wear.

Will this cover let rainwater through and can I use it during swimming season?

This is a solid winter cover that does not permit water to pass through the material, so rain and meltwater remain above the sheet until removed. It is intended exclusively for off-season winter protection and is not designed to be a seasonal debris cover while swimming is active.

• Solid construction blocks precipitation and large debris from entering the pool.
• Not a breathable or water-permeable type; pooled water stays on top.
• Remove before the swimming season — use a dedicated mesh or safety cover for in-season debris management.
• Water must be manually removed from the cover surface if desired (siphon or pump).

Who is this for: The Robelle 20 x 40 ft Economy Winter Pool Cover suits inground pool owners seeking a no-frills, reliable winter barrier with extra overlap for easier installation. It's a good fit if you want a solid cover that blocks winter debris and snow, prefer a trusted brand with decades of experience, and are prepared to use vinyl water weights for proper installation. If your pool has built-in steps, benches or irregular shapes that project beyond the rim, consider sizing up to ensure the cover floats freely without tension.
