Pool Blaster CX-300
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.

The Dolphin 500966 is a lightweight, entry-level robotic cleaner with smart navigation and a top-load filter, ideal for small above-ground pools. Its main trade-offs are the lack of wall-climbing ability and missing smart-app features. Best suited for owners who need a simple, low-maintenance floor-only solution.

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.

Choose the 500966 for a lower-cost basic model; choose the E10 if you want a newer version with similar capabilities.
