I ran the Aiper Surfer S2 almost continuously for four months; solar charging usually kept up, but a later charging fault led to a warranty replacement.
I bought an Aiper Scuba S1 Pro in December 2024; it failed in March 2026, and the used S1 replacement later failed too. I explain the warranty dispute.
My Aiper Surfer S1 keeps the pool surface clear. The Scuba S1 Pro has been harder to live with: a charging failure, a repair and erratic cleaning routes.
My Aiper Scuba X1 broke down twice in just over six months. Even between failures, retrieving it and washing sand out of the filter have been a struggle.
I have used a Beatbot cordless pool cleaner, but it hasn't replaced my brushes and net. Fine debris can remain, and cloudy water can make manual retrieval harder.
My Dolphin X20 picked up dust, seeds and bark in one pass. The pool floor looked almost fully covered, though the steps and edges still needed attention.
After two months, my Dolphin X20 cleans much like my old robot, but its cable tangles less. I also tried a cheaper fine filter in my leafy 6 × 9 m pool.
