Goplus Pool Cover 20 x 40 ft Solar Blanket - Heats & Reduces

In this review of the Goplus Pool Cover 20 x 40 ft solar blanket, the bottom line is simple: this is a practical, low-effort way to keep pool water warmer and cut evaporation for owners of rectangular or irregular in-ground and above-ground pools. The cover's thousands of tiny bubbles capture solar energy and can raise water temperature noticeably, while the 12 MIL thickness and included carrying bag make handling and storage straightforward. For anyone who wants easier maintenance and a longer swimming season without installing expensive equipment, this pool blanket delivers clear, measurable benefits.

Key Features

• Solar heating: Thousands of bubble cells collect and transfer solar energy to raise water temperature by up to 14-27F (8-15C) depending on local conditions.
• Evaporation control: The cover helps prevent up to 95% of water evaporation, which reduces top-offs and water bills on hot days.
• Debris protection: The blanket keeps dust, leaves and other debris out of the pool, cutting skimming and filtration work.
• Trim to fit: The rectangular sheet can be cut to fit in-ground or above-ground pools, spas and hot tubs in non-standard shapes.
• Durable material: Constructed from 12 MIL PE, the blanket is thicker than lighter solar covers and is intended to heat water faster and resist wear.
• Portable storage: Includes a carrying bag with handles so the folded blanket is easier to store and transport.

Who It's For

The Goplus 20 x 40 ft solar blanket is best for homeowners with mid- to large-size rectangular pools who want a low-cost way to extend their swimming season and reduce water loss. It also suits owners of above-ground pools, spas and hot tubs who need a cover that can be trimmed to fit non-standard shapes and who value ease of use over permanent equipment.

People who require a long-term, heavy-duty commercial solution or who expect multi-year, worry-free tear resistance in harsh conditions might prefer a thicker, reinforced cover or a mechanical reel and premium material. Those needing a perfect custom fit without cutting may want a tailored manufacturer cover instead.

Pros & Cons

Pros

• Effective at raising water temperature and helping retain heat overnight, delivering a noticeable comfort gain.
• Reduces evaporation significantly, saving water and lowering refill frequency.
• Simple to cut and trim to fit different pool shapes, and easy to fold into the included carrying bag for storage.
• 12 MIL thickness offers more substance than ultra-thin alternatives, aiding durability and heating speed.

Cons

• Durability opinions are mixed; some users report tearing after extended use, so heavy-duty longevity may vary by climate and handling.
• Manual handling and trimming are required for non-rectangular pools, which adds time and effort compared with custom-fit covers.
