Spec, translated

The '150 Min Runtime for...2600 Sq.ft' claim refers to a best-case scenario on a flat floor. Expect significantly less coverage area when the robot expends energy climbing walls, which is its main selling point.

Lab notes

The observations that actually change the buying decision.

At $300, this unit includes wall-climbing hardware (triple brushless motors, sensors) usually found in models costing twice as much; the primary compromise will be in software, climbing consistency, and component quality.

A 150-minute runtime is ambitious for a cordless wall-climber. The battery capacity is not disclosed, suggesting it may struggle to complete full wall/waterline cycles in large pools before needing a recharge.

The use of gyroscopes and ultrasonic sensors is notable for this price point, but effective path-planning is software-dependent. Expect better-than-random coverage, but not the systematic cleaning of a premium robot.

The 4L top-load filter is a good usability feature, but the term 'fine filtration' is meaningless without a micron rating; it will likely capture leaves and sand but may pass fine silt.

Why you should buy

This is for the pool owner on a strict budget who wants to try a cordless wall-climber and is willing to accept inconsistent performance. It's a gamble on getting 70% of a high-end cleaner's features for 40% of the price.

Why you should skip

Anyone with a large or complex-shaped pool who needs reliable, repeatable cleaning should skip this. If you value proven longevity and manufacturer support over a low initial price, look to established brands.
