Xmnbl "2026 Upgrade" Automatic Pool Filler
SKIP: about $46, and its newest complaints are about flooded yards — Xmnbl's "2026 Upgrade" filler is a light plastic deck unit you weigh down with stones, with a float you turn to set the level and an inlet filter Xmnbl added this year. Owners give it 4.0★ across 970, and its title promises "5 Years Warranty". The catch: 16% of its ratings are one star, and 7 of its 10 newest written critical reviews describe it overfilling the pool, one for three weeks while the owner travelled and one at a $1,000 water bill. Xmnbl's own listing tells buyers to check "the sealing and water level control function of the product after you receive the goods" to "Avoid continuous injection of pool water overflow".
