Robot pool cleaners worth it, or an expensive toy?
A robot pool cleaner is a self-contained machine with its own motor and filter. That is the key difference from suction and pressure cleaners, which rely on your pool pump to work.
It is also why they cost more, and whether that premium is worth paying depends mostly on your pool rather than the machine.
AquaSense 2 Pro
Full coverage including the waterline
Floor, walls and waterline in one machine. The waterline is where the visible grime sits, and cleaners that skip it leave the part guests actually look at.
Nautilus CC Plus Wi-Fi
The dependable mid-range choice
A long track record and widely available parts. For a machine that lives in water and works hard, serviceability matters more than feature lists.
Why independence from the pump matters
Suction cleaners use your pump, which means running the pump longer, loading your filter with debris, and paying for the electricity of a much larger motor.
A robot runs its own small motor and catches debris in its own basket. Your filter stays cleaner, backwashing is less frequent, and total energy use is usually lower despite being an extra appliance.
Where they earn the money
Large pools, pools under trees, and anyone who currently spends real time brushing. The cost comparison is not against a cheaper cleaner, it is against the hours you spend or the service you pay.
They also protect the equipment you already own. Keeping leaves and grit out of your filter and pump extends the life of both, which rarely features in the purchase decision but should.
Where a cheaper cleaner is fine
A small pool with a cover, little overhanging vegetation and a pump that runs anyway will do perfectly well with a suction cleaner at a fraction of the price.
Be realistic too about lifespan. These machines live in chlorinated water and take a beating. Check parts availability for the model you are considering, because a cleaner you cannot repair is a short-term purchase at a long-term price.
