Can I leave my pool cleaner in the water all day?
Robots are designed to be water resistant, but not indefinitely
Pool robots are designed to operate underwater. Their components are generally waterproof and protected against splashes and submersion, especially for battery-powered robots. Top-of-the-range models such as the Beatbot AquaSense Pro or the Dolphin Liberty even have high protection standards (IPX8) guaranteeing operation in full immersion. However, this does not mean they should be left in the water permanently. Continuous exposure to moisture, chlorine, salt (for saltwater pools) and UV rays can, over time, damage seals, the casing or even internal electronic components. Some manufacturers specify that the robot should be removed after the cleaning cycle to ensure longevity and preserve the warranty.The risks of prolonged immersion
Leaving your pool robot in the water all day—or for several days—can have several disadvantages:- Premature wear of seals due to continuous exposure to chemicals.
- Slow internal corrosion if seals begin to weaken, especially in saltwater pools.
- Limescale or algae deposits on wheels, brushes, or other submerged parts.
- Reduced performance if filters remain wet and clogged for too long.
What the manufacturers say
Most brands recommend removing the robot after each cycle. Dolphin, Zodiac, Hayward and Beatbot advise that if the appliance is not in use, it should be rinsed with clean water, its filters emptied, and then stored in the shade to prevent mould, algae or unpleasant odours in internal compartments.Only the iSkim Ultra, designed for continuous surface cleaning and powered by solar energy, is intended to float 24/7 without risk. In short, let your robot do its job—but not longer than necessary.
