Robelle 18 x 33 ft Blue Winter Oval Pool Cover - Solid Protection

Our review of the Robelle 18 x 33 ft Blue Winter Oval Pool Cover finds it best for above-ground pool owners who want a simple, solid barrier against winter elements. The single biggest reason to buy is straightforward: it is a heavy-duty solid cover with a 3 ft overlap and included winch and cable, designed to float loosely on the water and resist high winds. The 2.2 oz/yd2 polyethylene with a 7 x 7 scrim gives clear expectations about durability and weight, while an 8-year warranty offers extra peace of mind.

Key Features

• Solid construction: The cover is a solid design so water does not pass through, keeping debris and meltwater out of the pool during winter.
• Generous overlap: A 3 ft overlap (cover size 21 x 36 ft) simplifies installation and helps the cover sit loosely on the pool surface.
• Durable material: Made from 2.2 oz/yd2 polyethylene woven with a 7 x 7 scrim, the material balance aims to resist tears and stretching.
• Winch and cable included: The included winch and cable make it practical to secure the cover through grommets and tension around the perimeter.
• Weather protection: Designed for snow and ice protection and optimized for performance in high wind areas when properly secured.
• Long warranty: Backed by an 8-year warranty that reflects the brand's confidence in the product's longevity.

Who It's For

This cover suits owners of 18 x 33 ft above-ground oval pools who need a robust winter barrier that keeps water out and resists snow and ice. It is intended for off-season use and is particularly useful for yards that experience high winds, since the winch and cable system supports a secure fit.

It is less suitable for someone who wants a lightweight, short-term solution or a cover intended for in-season debris control. Also, owners with very large top rails should consider sizing up so the cover can float without excessive stress.

Pros & Cons

Pros

• Solid, non-porous material prevents water from seeping into the pool through the cover.
• Includes winch and cable, which simplifies securing the cover around the pool perimeter.
• 3 ft overlap and 2.2 oz/yd2 weight with 7 x 7 scrim provide a durable feeling and easier installation than tighter-fit covers.
• 8-year warranty offers long-term assurance backed by the brand's decades of pool-cover experience.

Cons

• Durability reports are mixed among users; some experienced early wear, so heavy-use environments could reveal limitations.
• Some customers find the cover bulky or slightly oversized for certain pool rail configurations, requiring a larger size or extra care during installation.

Our Verdict
