Score: 80/100Rankings

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.

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.
