Installation Requirements
1. Maintain a space of approximately 30.5 cm in height, 40cm in width, and 120 cm in depth.
2. Position the dock on a hard and even floor (wood, tile, concrete, etc.), flush against a wall. Avoid placing it on soft surfaces (carpet, mat, etc.) and in narrow areas.
3. Ensure that the location has a strong Wi-Fi signal for an optimal experience with the mobile app.
4. The height difference at any point on the drainage pipeline from the ground is recommended not to exceed 50 cm.
5. The installation distance for the water refill and outlet pipes is recommended within 6 meters. If this is not possible, please contact customer service for consultation.
6. The water pressure range is 0.1-0.4MPa. If it exceeds 0.4MPa, please use a pressure-reducing valve.
7. The pipeline layout should avoid passing through room doorways to prevent accidental breakage due to household traffic.
8. Ensure there are no thresholds, tracks, or steps higher than 2 cm between the dock's installation site and the cleaning area to avoid the risk of getting stuck or missed cleaning.
9. Before installation, please disconnect the power supply of the dock. Turn off the main water supply switch, faucet switch, or angle valve switch in the house. Drain any remaining water from the pipes, and ensure they are connected without leakage before powering on.
