Aiper Scuba S1
Score: 79/100Rankings

The Pool Blaster CX-300 is a cordless robotic cleaner with strong suction and wall-climbing ability, ideal for pools up to 150 m². Its heavier weight and occasional runtime reductions are notable trade-offs. Best for homeowners who prioritize cordless convenience and robust cleaning over ultra-light portability.

The Aiper Scuba S1 is a high-end cordless robotic pool cleaner delivering industry-leading suction and a long 180-minute runtime. Its premium price and heavy chassis make it less suitable for budget-focused or portable users. Best for large in-ground pools needing thorough cleaning.

Professional reviewers and the manufacturer stress the high efficiency of the CX-300, noting its powerful 7,200 gal/hr suction, cordless low-power operation, and wall-climbing navigation as standout features. However, experts caution that warranty details are inconsistently presented and the unit's weight may be a drawback compared with lighter rivals.
Everyday users generally praise the cordless convenience, strong suction, and wall-climbing capability, especially for sandy or silty pools. Recurring themes include appreciation for the fine-mesh filter and the retrieval hook, while common complaints focus on the robot's heavy weight and occasional runtime reduction in heavily soiled water.

Professional reviewers agree that the Aiper Scuba X1 Pro Max sets a new benchmark for suction and runtime, delivering unmatched cleaning power for large in-ground pools. However, they also note its premium price, heavy chassis, and limited automation features as trade-offs that may deter budget-oriented buyers.
Consumers overwhelmingly praise the robot's thorough, spot-free cleaning and the freedom of a cordless system, but they consistently flag the heavy weight, long charge time, and the need for regular filter upkeep as pain points.
