A pool robot moves on its own across the floor and walls, vacuuming up dirt, leaves and sand while you do something else. It keeps the pool clean with less effort and fewer chemicals, because it collects debris before it settles and breaks down. The right choice, though, depends on the shape and size of the pool, the type of surface and how the robot is powered.
How it works
The robot rests on the pool floor, moves on tracks or wheels and sucks water through an internal filter. Many models also climb the walls and clean the waterline, and some return automatically at the end of the cycle. The route can be random or programmed, and the more advanced models use sensors to avoid obstacles and cover the whole surface.
Types of robot
- Battery models: easier to handle, with no cables in the water. The battery lasts one cycle and needs recharging between uses.
- Corded models: they run longer and with more power, but the cable must be handled carefully, unrolled and rewound without twists or knots.
- Pressure or suction models: they use the flow from the pool’s filtration system or a dedicated pump. They are cheaper but often less effective on fine sediment.
Choosing for your pool
Consider the shape and size of the pool: rectangular ones are simpler, while irregular pools or those with steps need a suitable robot. Check the type of surface, because tiles, liners and concrete have different needs, and some robots don’t work well on surfaces that are too rough or too slippery. Also make sure the robot is compatible with your pool’s walls and has a filter that is easy to empty.
Electrical safety
Even with a battery robot, charging happens near water, so be careful. Use only the supplied charger, check that the socket is protected by a residual current device (RCD), and keep the charger away from damp. For corded models, check that the power supply is certified and placed away from the water and out of reach of splashes. Never touch the robot with wet hands while it is plugged in.
Maintenance
After every cycle, empty the filter, rinse the brushes or tracks and check that the wheels turn freely. Store the robot somewhere dry and out of the sun, and follow the manufacturer’s instructions for winter storage. A clean robot lasts longer and works better.
A good pool robot pays for itself in fewer hours of brushing and fewer chemicals. Choosing the right type for your pool and using it with care make all the difference.
