Robelle Olympus 18 x 33 ft Oval Winter Pool Cover for Above-Ground Pools — Extra Heavy-Duty Solid Cover with Winch

The Robelle 18 x 33 ft Olympus Winter Oval Pool Cover is an extra heavy-duty solid winter cover built to keep above-ground pools closed, dry and protected through the off-season.

This solid winter cover is engineered for above-ground oval pools and combines a dense polyethylene weave with Rip-Shield reinforcement to resist tearing, hold up under snow load, and keep leaves and grit out of your pool while you’re not using it. Robelle’s Olympus cover uses a 13 x 11 scrim and a 3.6 oz/yd² material weight—specifications that emphasize durability—plus an included winch and cable to secure the perimeter. The cover is blue on top and black underneath, and it provides a four-foot overlap beyond the pool edge so installation is easier and the cover floats freely on the water.

How will this cover hold up through winter weather?

The Olympus cover is made from extra heavy-duty woven polyethylene and features Rip-Shield Technology that prevents small punctures from turning into larger tears. Its solid design blocks water and debris, reducing maintenance at spring opening. Robelle backs the engineering with a long warranty and a manufacturing focus on rugged seasonal protection.

• 13 x 11 scrim for strong weave stability
• 3.6 oz./yd² material weight for enhanced tear and wear resistance
• Rip-Shield reinforcement to arrest small rips
• Solid, non-permeable construction to keep out leaves and dirt

What installation tools and steps are included?

The cover ships with a winch and cable sized to fasten through the grommets around the cover’s edge so you can tension it evenly. The four-foot overlap is intended to drape over the pool top rail and help the cover float without undue strain; for very tall top rails you may prefer ordering the next size up. Robelle recommends using the supplied winch and cable as the primary securing method.

• Included winch and cable for perimeter attachment
• Grommets spaced around the edge for cable threading
• 4 ft overlap (cover measures 22 x 37 ft including overlap)
• Optional cover clips, wrap, or water weights sold separately for extra security

Will this cover work for oval above-ground pools with decks or heavy top rails?

Yes — the cover is designed for traditional above-ground pools with a standard top rail. For pools with decks, install the cover over the deck and use vinyl water weights on top; for partial decks, combine deck weights with the winch and cable run under the deck when possible. If your pool has an unusually large top rail, choosing a larger cover size will ensure the cover floats and avoids excess stress at the edges.

• Designed for traditional above-ground oval pools and top rails
• Use water weights on decks; cable under deck for partial decks
• Consider sizing up for very large top rails to prevent tight drains on the material
• Not intended as an in-season debris or solar cover

How does Robelle support product longevity and owner confidence?

Robelle has over five decades of pool-cover experience and builds the Olympus cover heavier than typical industry standards. The company pairs higher material weight and scrim counts with manufacturing controls such as reinforced stitching and quality grommets, and stands behind the product with an extended warranty that reflects confidence in long-term performance.

• Manufactured heavier than many standard winter covers
• Backed by Robelle’s long-standing warranty and reputation
• Designed specifically for off-season protection, not for everyday debris control
• Blue top/black underside for classic appearance and UV resistance

Who is this for: The Robelle 18 x 33 ft Olympus Winter Oval Pool Cover is aimed at above-ground pool owners looking for a rugged winter solution that minimizes spring cleanup and resists tear propagation. It’s ideal if you want a solid, tightly woven cover with a generous overlap, included winch and cable, and an engineered design meant to withstand snow, ice pressure, and wind when properly secured. If you need seasonal debris control during swimming months, consider a different cover type designed for in-season use.
