Cordless Pool Cleaning Robot: How to Choose the Right Model for Your Pool

A cordless pool cleaning robot makes maintaining an above-ground or in-ground pool effortless, with no trailing cable or connection needed during cleaning. But the advertised battery life, navigation system or filtration fineness alone aren't enough to guarantee the right choice. Before comparing models, check your pool's shape, its surface area and the areas you actually want to clean.

Common Pitfalls Before You Buy

1. Confusing Battery Life with Actual Coverage

A battery life of 120 or 180 minutes doesn't guarantee the robot will cover the entire pool. The result depends on the surface area to be cleaned, the depth, the shape of the floor, any obstacles and the programme selected. A model limited to the floor won't suit a pool where the walls and waterline also need attention.

2. Relying Solely on Suction Flow Rate

Expressed in litres per hour or cubic metres per hour, the flow rate gives a useful indication, but it isn't enough to judge cleaning effectiveness. The design of the brushes, the grip of the tracks, the size of the suction inlet and the filtration system all play a crucial role too. A powerful suction can even become a hassle if the basket is too small or difficult to rinse.

3. Overlooking Compatibility with Your Pool

A cordless pool robot must be compatible with the minimum and maximum depth specified by the manufacturer. Some models climb walls, while others are limited to flat-bottomed pools. Also check their compatibility with liner, reinforced PVC, tiles, painted concrete, mosaic or polyester shell.

Technical Criteria to Check

Surface Area, Depth and Cleaning Zones

Start by measuring your pool's surface area and clearly define the tasks you expect:

  • Floor only for routine maintenance of a flat-bottomed above-ground pool.
  • Floor and walls to reduce the need for manual brushing.
  • Floor, walls and waterline when debris builds up near the water's surface.
  • Water surface to remove leaves, insects and floating pollen.

A pool robot for floor, walls and waterline needs suitable traction, usually provided by tracks or wheels with good grip. Also check for a parking function or a retrieval hook.

Battery Life and Charging

For a small pool, a battery life of 75 to 90 minutes may be enough if the robot only cleans the floor. For a larger pool or maintenance covering multiple surfaces, it's better to look for a long-lasting pool robot. The advertised duration varies depending on the programme used: cleaning walls generally requires more energy than a floor-only cycle.

The charging time also deserves your attention. A rechargeable pool robot that regains full battery in 2.5 to 4 hours fits more easily into a regular maintenance routine. Always charge the device in a dry place and follow the manufacturer's instructions.

Filtration, Maintenance and Safety

Filtration fineness is measured in microns. A value of 180 µm is sufficient to trap leaves, insects and common debris. A 120 µm filter captures finer particles, while a 3 µm filter targets particularly fine filtration, at the cost of potentially more demanding maintenance and replacement.

After each cycle, remove the basket, empty the debris and rinse it with clean water. With fine filtration, the flow rate can drop quickly if the filter becomes clogged. For water protection, look for a certification such as IPX8 or IP68. Also follow the usage rules: never handle the robot while it's operating, don't charge it near water, and remove it from the pool before swimming.

Frequently Asked Questions About Cordless Pool Robots

Is a cordless robot suitable for both above-ground and in-ground pools?

Yes, some models are designed for both types of pools. However, check for the "flat floor" mention, the ability to climb walls, the maximum surface area covered and compatible linings. A device limited to the floor won't replace a robot suitable for above-ground and in-ground pools that can also clean the walls.

How much does it cost to use a rechargeable pool robot?

The cost mainly depends on the electricity consumption for charging, the frequency of cycles and the replacement of filters or brushes. A full charge generally uses less power than prolonged operation with a more powerful motorised system, but check the power rating stated by the manufacturer and your electricity tariff. Rinsing the filter after each use also helps maintain optimal flow.

What lifespan can you expect from a robotic pool cleaner?

It depends on sun exposure, storage conditions, water quality and maintenance. After each cycle, rinse the robot and its filter, let them dry according to the instructions in the manual, then store the device away from frost and direct sunlight. Don't leave it submerged permanently and only use the charger supplied or recommended by the manufacturer.
