"It has app control and wall-climbing features rare for the price, but the filtration is coarse."
The 3,038 GPH flow rate means it has sufficient power to lift leaves and twigs, but the 185-micron filter is coarse, so fine sand and silt may pass right through.
This is for the pool owner prioritizing the convenience of app control and automated wall cleaning over perfect filtration. If your main problem is leaves and larger debris, the value proposition is strong.
Pool owners battling fine silt, sand, or algae should seek a unit with a much finer filter (sub-100 microns). Those with slick-tiled pools may also find the PVC brushes provide insufficient grip compared to foam rollers.
