Pool Cleaning Robots: Buying Guide and Recommendations
Keeping the bottom of the pool clean is a necessary task, but it can be very time-consuming if done manually with a vacuum hose. Automatic pool cleaning robots have revolutionized the maintenance of home pools: they operate autonomously, clean the floor, walls, and even the waterline, and return to their starting point when they’re done. But choosing the right model isn’t easy.
Types of Pool Cleaning Robots
Hydraulic robots: These are the most basic and economical models. They operate by connecting to the pool’s pressure or suction inlet, using the water pressure from the filter pump to move around and suck up debris. They are easy to maintain and do not consume their own electricity, but their range and coverage are limited. They are suitable for small pools with light debris.
Autonomous electric robots: These are the most popular and efficient option. They operate using a low-voltage transformer, making them completely safe in the water. They have their own motor, internal filtration pump, and filter bag or cartridge. They are completely independent of the pool’s filtration system. Most include scheduled programming, systematic (non-random) navigation, and the ability to clean walls.
Pressure-driven robots: These operate by connecting to the pool’s discharge outlet, using the water jet to propel themselves and push debris toward the skimmer or into their own collection bag. They offer a mid-range option in terms of price and performance.
Features to Consider
Before buying, consider these factors:
— Cleaning area: Just the bottom, or also the walls and waterline? The most comprehensive models clean all three areas.
— Filtration system: Bag or cartridge. Cartridges trap finer particles (up to 2 microns) and are easier to clean.
— Propulsion type: Wheels (best on smooth surfaces) or tracks (better traction on textured walls and bottoms).
— Navigation: Random (more economical, less efficient) or systematic with mapping (more expensive, guaranteed full coverage).
— Corded or cordless: The latest models are cordless (lithium battery), which eliminates the problem of tangled cords.
— Session duration: Between 1.5 and 3 hours, depending on the model and the size of the pool.
— Ease of emptying and cleaning: An ergonomic design saves time and reduces frustration.
Price Ranges
The market offers options for every budget:
— Entry-level (€300–600): Basic robots, typically hydraulic or electric, without wall cleaning. Suitable for small, rectangular pools.
— Mid-range (€600–1,200): Electric robots with wall cleaning, good coverage, and efficient filtration. Excellent value for the price.
— High-end (€1,200–2,000+): Advanced systematic navigation, Wi-Fi connectivity with an app, cordless operation, and ultra-fine filtration. Ideal for large or irregularly shaped pools.
Compatibility with Reinforced PVC Liner
This is a critical point that many buyers overlook. Pools lined with reinforced PVC liner require robots with certain features to avoid damaging the liner:
— Avoid models with hard, abrasive brushes or wire brushes: they can scratch or wear down the liner’s surface. Look for models with soft PVC or microfiber brushes.
— Opt for robots with soft rubber track traction: they distribute weight more evenly and do not concentrate pressure on specific points.
— Models with adjustable suction pressure are worth considering: on very soft liners, it may be helpful to reduce the suction so the robot doesn’t get stuck or slip.
The leading manufacturers (Dolphin, Zodiac, Hayward, Fluidra) feature models in their catalogs that are specifically recommended for pools with PVC liners. Always check compatibility before purchasing.
