How to Use a Pool Cleaner with a Solar Cover

Why Solar Covers and Pool Cleaners Clash

Solar covers float on the water surface to retain heat and reduce evaporation. They can cover nearly the entire pool, leaving only a thin margin of open water. Automatic pool cleaners, whether they are suction, pressure, or robotic, are designed to travel along submerged surfaces. When the cover is in place, the cleaner may accidentally pull the cover toward the skimmer (suction type), wrap the hose around it (pressure type), or climb onto the cover and get stuck (robotic type).

The cover material is often a lightweight plastic or foam that tears easily if the cleaner catches an edge. Both the cover and the cleaner can suffer damage, and a torn cover loses its insulating benefits. According to ENERGY STAR, a pool cover can reduce heating costs by as much as 50% to 70%, so protecting it is also a financial consideration. Understanding the interaction is the first step to safe operation.

Best Practice: Remove the Cover First

The safest and most effective method is to remove the cover completely before you start any automatic cleaner. This holds true for every type: suction, pressure, and robotic. Removing the cover gives the cleaner uninterrupted access to the pool floor, walls, and waterline, and it prevents accidental entanglement.

Use a cover reel to make removal quick and straightforward. A reel also helps you store the cover without folds or creases that can trap water or debris. Follow these steps for a smoother routine:

• Roll up the cover using a reel or by hand, starting from the shallow end.
• Store it on the deck, away from foot traffic and direct sunlight when not in use.
• Start your cleaner and allow it to run its full cycle. For robotic models, place the unit in the water after the cover is removed.
• While the pool is uncovered, inspect water clarity and adjust chemicals if needed.
• Once cleaning is done, replace the cover, ensuring it is fully spread and not blocking any skimmers.

If You Must Clean With the Cover On

If circumstances force you to clean without removing the cover, avoid automatic cleaners entirely. Reach for a telescoping pole with a mesh net or a battery-powered handheld vacuum. These tools can remove debris without disturbing the cover.

If you still attempt to run a robotic cleaner with the cover on, inspect the cover for existing tears and pinch points. Secure the cover edges with clips or weights to reduce the risk of it being pulled. Watch the cleaner throughout its cycle and stop it if it starts to lift the cover. This is only a temporary measure and should not replace the regular practice of removing the cover. For more on untangling, refer to our guide on untangling pool cleaner cords.

Protect Both Your Cleaner and Your Cover

Regular maintenance protects both investments. Check the cleaner's hose, power cord, and wheel hubs for wear or kinks. Examine the underside of the solar cover for abrasion marks, especially along seams and near the skimmer. If the cleaner becomes stuck, turn off the power and gently lift the cover to free it. Never pull forcefully, as that can rip the cover or damage the cleaner.

Many robotic cleaners incorporate anti-tangle swivels and soft-touch wheels to handle obstacles, but they are not designed to work beneath a floating cover. Always store the cover rolled and dry to prevent cracking. For more on avoiding tangles, see our guide on preventing pool cleaner tangling. Additionally, check the swivel and anti-tangle guide to understand how different designs reduce risk.

Choosing a Cleaner That Works With Your Routine

When you use a solar cover, the cleaner you choose affects your daily routine. Robotic cleaners are the most convenient because they are independent of the pool pump and can be placed in the water after the cover is rolled back. Many models from brands like Maytronics and Aiper are cordless, so you can simply set them on the water and start the cycle. See our best cordless robotic pool cleaners for examples.

If you own a suction-side or pressure-side cleaner, you must always confirm the cover is clear of the skimmer and return fittings. These cleaners rely on the pool's plumbing, and a floating cover can obstruct the flow. For a comparison of the three main types, read our robotic vs. suction vs. pressure guide. Also consider the cable length guide if you are extending your cleaner's reach.

Build a Cleaning Schedule Around Your Cover

Many pool owners automate their cleaner with a timer. When you use a solar cover, adjust that schedule to start only after the cover has been removed. This might mean running the cleaner in the morning before you cover the pool for the day, or after swimming when the cover is off.

If your pool is empty most of the day, you can remove the cover in the morning, let the cleaner run for its full cycle, then re-cover. That way the pool is clean and the cover still retains heat overnight. Some robotic cleaners allow you to set a delay or remote start, so you can roll back the cover and start the cycle with your phone.

Manual Cleaning as a Backup

Even if you rely on automatic cleaners, keeping a manual skimmer and a handheld vacuum is wise. These tools are essential for quick touch-ups on days when the cover stays on, or when a heavy storm has deposited leaves and twigs. Manual cleaning also allows you to target specific areas without disturbing the cover.

When using a handheld vacuum, follow the manufacturer's instructions for debris bin and battery care. If you have a cordless model, check the battery level before starting. For more on manual cleaning, see our robotic vs. manual cleaning guide.

What to pick for your use

Questions

Can I run my pool cleaner with the solar cover on?

Technically you can, but it is risky. The cover can be sucked in or wrapped around the cleaner, causing damage. The safest practice is to remove the cover completely each time.

What should I do if my cleaner gets tangled in the cover?

Stop the cleaner immediately and switch it off. Gently lift the cover and release the cleaner, checking for any tears. If the cover is damaged, repair it before using again.

How do I prevent my cleaner from pulling the cover?

Remove the cover before cleaning. If you must keep it on, secure the edges and monitor the cycle. Regular inspection of your cleaner's hoses and swivels also reduces risk.

Is a robotic cleaner better with a solar cover?

Robotic cleaners are easier to manage because they are cordless and independent of the pump, but they still should not run under the cover. Removing the cover remains the best approach.

What is the best way to store a solar cover?

Store it rolled up on a reel, off the ground and protected from direct sunlight. This prevents cracking and keeps the cover ready for quick removal before cleaning.
