Domakihub Robotic Pool Cleaners: How to Buy Smart and Keep Them Running
Choose the right robot for your pool size, save hours of maintenance, and extend the machine's life with simple care habits.

Greece's long swim season — often running from April through October — puts pool equipment under serious strain, and robotic cleaners have become the single biggest time-saver for villa owners, holiday-rental managers, and hotel maintenance teams alike. The video above walks through hands-on testing of more than 30 models so you can see real performance before you spend; this guide picks up where the footage leaves off, giving you the buying criteria and care routine you need once the robot arrives. Whether you run one private pool or a portfolio of rentals across the islands, the same principles apply: match the machine to your pool, then look after it consistently.
Why Robotic Cleaners Make Sense for Greek Pools
Greece's combination of fine sand blown in from Saharan dust events, high UV, and heavy seasonal use means pool walls and floors accumulate debris faster than in cooler climates. A quality robot runs a dedicated cleaning cycle without taxing the main filtration pump, which cuts electricity costs and reduces chemical consumption — two factors that matter when the meter is running on a tourist-rental property.
Unlike suction-side or pressure-side cleaners, robotic models carry their own filter basket and motor. That means the main pump can focus on water circulation, and you are not recirculating captured debris through the system if you forget to empty the bag promptly.
Key Specs That Actually Matter at Purchase
Pool size and shape determine everything else. A robot rated for up to 10 m is undersized for a 14 m villa pool and will simply stop before the job is done. Check the stated pool length, confirm whether the model climbs walls and cleans the waterline — many budget units only scrub the floor — and look at whether the cable length is genuinely long enough for your pool without tangling.
Filter-basket surface area is the spec most buyers ignore and most regret. Fine-filter cartridges trap the sub-50-micron particles (algae spores, fine dust) that a standard mesh bag misses. If your pool sits near a garden or olive grove, or you host guests who apply sunscreen, go for the finer filtration option even if it costs slightly more to maintain.
5 Steps to Buy, Set Up, and Maintain Your Pool Robot
- 1
Match the robot to your pool's dimensions and shape
Before browsing models, measure your pool's longest dimension and note whether it is rectangular, freeform, or has steps and ledges. Choose a robot rated for at least 10–15 % more than your actual pool length to give the navigation algorithm enough room to complete a full cycle. If your pool has a tiled waterline or stubborn algae on vertical walls, confirm that the model you are considering explicitly lists wall climbing as a feature — not all do.

Choose the right filtration level for your conditions
Standard mesh bags handle leaves and coarse debris well but let fine particles pass back into the water. If your property is near the coast, in an olive-growing area, or hosts guests regularly, opt for a cartridge-filter model with a fine-pore insert. You will rinse the cartridge more often, but your water clarity will improve noticeably and you will use less clarifier over the season.

Set up the cable and timer correctly on day one
Lay the cable in a loose figure-eight on the pool deck rather than a straight line; this prevents the robot from tangling as it turns. Plug the power supply into a weatherproof outdoor socket with a residual-current device (RCD) — mandatory in Greece under electrical safety codes. Set the built-in timer or app schedule to run the robot when the pool is not in use, typically early morning, so it finishes before the first swim of the day.

Clean the filter basket after every single cycle
Remove the robot from the water using its handle or the provided caddy — never by the cable. Open the filter compartment, rinse the basket or cartridge under a garden hose, and inspect it for tears. A clogged filter cuts suction, overheats the motor, and shortens the robot's life significantly. Rinsing takes under two minutes and is the single highest-impact maintenance habit you can build.

Store and service the robot correctly between seasons
At the end of the swim season, rinse the robot thoroughly with fresh water, allow it to dry in the shade, and store it in a cool, dry place out of direct sunlight — UV degrades the plastic housing and drive tracks over time. Inspect the brushes and drive belts before storage; replace them if worn so the robot is ready to go next spring. If you notice reduced suction or erratic navigation mid-season, check the impeller for hair and debris before calling a technician.

FAQ
- How long does a robotic pool cleaner cycle typically take?
- Most models complete a standard cycle in 1.5 to 3 hours depending on pool size and the cleaning mode selected. Some have a quick 90-minute mode for light maintenance and a longer 3-hour deep-clean mode. Running the robot daily on a shorter cycle is usually more effective — and gentler on the machine — than running it once a week on a marathon session.
- Can I leave the robot in the pool permanently?
- No. Robotic cleaners should be removed from the water after each cycle. Leaving them submerged exposes the electronics and seals to prolonged chemical contact and UV when the robot floats near the surface. It also means the cable sits in chlorinated water continuously, shortening its life. Lift it out, rinse it, and rest it on the provided caddy or a clean surface on the deck.
- How does a robotic cleaner affect my pool's chemical balance?
- Robotic cleaners do not directly alter chemical levels, but they improve water clarity by removing fine particles that can harbour bacteria and consume chlorine. A well-cleaned pool typically requires less shock treatment and stabiliser top-ups over the season. Run your normal chemical checks on the same schedule regardless — the robot complements chemical management but does not replace it.
