When winter arrives, your robotic pool cleaner needs more than just a quick rinse before being tucked away. Snow, freezing rain, and gusty winds can damage sensitive electronics, crack plastic casings, and leave your equipment vulnerable to rust. A dedicated caddy cover designed for winter storage acts as a barrier against these elements, keeping your investment safe until pool season returns. In this guide, we have evaluated ten top-rated covers from brands like Aacabo, TonGass, Shappy, and Dolphin to help you find the best pool cleaner caddy cover for winter storage in 2026. Whether you own a Dolphin unit or a generic model, there is a cover here that fits your needs.
Winter storage demands more than just basic dust protection. A quality cover must be waterproof, windproof, and breathable to prevent condensation buildup.

Buying Guide
Waterproof and Weather Resistance
Winter brings rain, snow, and melting ice. A cover with a waterproof coating or laminated undercoating prevents moisture from seeping through and damaging your cleaner. Look for materials like 420D Oxford cloth or heavy-duty polyester with a water-resistant layer. The Aacabo Caddy Cover uses 420D polyester with a laminated undercoating, offering reliable protection against rain and frost. Similarly, the EVRBUL cover features 420D fabric that blocks rain while remaining breathable.
Breathability is equally important. A completely sealed cover can trap humidity inside, leading to corrosion and mold. Most premium covers include air vents or mesh panels that allow airflow while keeping out snow and debris. This balance between waterproofing and ventilation is critical for long-term winter storage.
Windproof Design
Strong winter winds can rip a loose cover off your caddy, leaving your cleaner exposed. Effective windproof features include drawstring hems, elastic edges, or hook-and-loop straps that cinch the cover tightly around the base. The SELUGOVE Pool Cleaner Caddy Cover has a drawstring rope at the edge that you can adjust to prevent blowing away. The best robotic pool cleaner cover for outdoor storage often includes multiple securing mechanisms for added stability.
Some covers also feature reflective strips for visibility in low-light conditions, which is a bonus if your caddy is stored near a driveway or walkway. The EVRBUL cover includes reflective strips on both sides, enhancing safety during winter evenings.
Material Quality and Durability
The cover must withstand UV rays, freezing temperatures, and physical abrasion. Heavy-duty 420D Oxford cloth or thick polyester is standard for long-lasting covers. The Shappy Robotic Pool Cleaner Caddy Cover uses 420D Oxford cloth with a waterproof liner, offering resistance to sun, snow, and wind. The TonGass cover is made of well-ventilated polyester that prevents humidity while remaining durable.
Pay attention to stitching and seams. Double-stitched seams and reinforced corners add longevity. The Premium 9991795-R1 cover from sixcow uses heavy-duty polyester and includes Velcro closures for a secure fit.

Compatibility and Fit
Not all caddies are the same size. Measure your caddy’s height, width, and depth before purchasing. Most covers are designed to fit standard residential models, but some are tailored for specific brands like Dolphin. The TonGass cover is an exact replacement for Maytronics part number 9991794-R1, fitting all residential Dolphin caddies. The DUDSOEHO cover measures 26 by 22 by 42 inches and fits most standard caddies with a snug custom-like fit.
If you have a Dolphin cleaner, the genuine Dolphin accessory bundle includes both a universal caddy and a classic cover, ensuring perfect compatibility. For other brands, universal covers from Aacabo and Shappy offer broad compatibility with most robotic pool cleaners.

Frequently Asked Questions
Can I use a regular tarp to cover my pool cleaner caddy for winter?
While a tarp offers basic protection, it lacks breathability and can trap moisture, leading to mold or corrosion. A dedicated caddy cover with vents and a secure fit is better for long-term winter storage in 2026.
How do I measure my caddy for a cover?
Measure the height from the base to the top handle, and the width and depth at the widest points. Most covers list dimensions in inches, such as 26 by 22 by 42 inches. Compare these to your caddy’s measurements for a snug fit.
Do I need a cover if my pool cleaner is stored indoors?
Indoor storage still exposes your cleaner to dust, humidity, and accidental bumps. A cover keeps it clean and protected, especially if stored in a garage or basement. For outdoor storage, a waterproof cover is essential.
Will a universal cover fit my Dolphin caddy?
Many universal covers are designed to fit most standard caddies, including Dolphin models. However, for a perfect fit, consider a cover specifically made for Dolphin, like the TonGass replacement or the genuine Dolphin accessory bundle.
