1. | What size of pool is this cleaner suitable for? |
This model is specially designed for small residential in‑ground pools. Compatible surfaces include tile, fiberglass, vinyl liner and smooth concrete. It fits rectangular, oval and compact irregular‑shaped pools. Not for large‑size pools, commercial public pools, saltwater pools, spas or hot springs. | |
2. | Why is suction weak or it cannot pick up dirt well? |
① The filter basket is clogged with debris; ② suction inlet is blocked by leaves or sundries; ③ battery power is low. Please clean the filter basket and suction inlet, and fully charge the cleaner before reuse. | |
3. | Can I turn on the cleaner out of water? |
Absolutely not. Dry‑running will damage the motor and waterproof seals, causing permanent damage. Always submerge the cleaner underwater before power‑on. | |

Power off and take out the cleaner. Remove and empty the filter basket, rinse thoroughly with clean water. Flush scrub brushes and tracks. Air‑dry in cool, shaded and ventilated place. Avoid long‑term direct sunlight. | |
7. | Why does it miss some corners? |
Avoid frequently dragging or moving the cleaner manually during operation, which interferes with navigation. Remove obstacles in corners. If debris builds‑up slows movement, clean filter basket in time. | |
