Automatic Water Supply and Drainage Base, Renovation Diagram

Pre-Installation Confirmation Information

Water Supply:
1. Municipal tap water, water pressure range: 0.14MPa-0.8MPa;
2. Water supply connector: The package includes a self-contained clean water three-way valve, which can be installed on standard angle valves or 1/2-inch faucets.


Drainage:
1. Please connect the sewage pipe to a floor drain or downpipe for drainage;
2. Since the base’s water outlet is in the lower area, if using wall drainage, please ensure the wall drainage height is ≤70cm. If the drainage height exceeds 70cm, it may cause poor drainage, leading to damage or sewage backflow.


Power Supply:
1. 220V alternating current;
2. Three-pin power socket (note: install a waterproof cover to avoid water splashing).


Environment Confirmation:
1. If embedding the product in a cabinet: Reserve height >30cm, depth >46cm, width >47cm; reserve 1m×47cm in the front area of the base;
2. Place the product in an open area (no doors/sliding doors) for easy robot entry/exit;
3. If there are doorsills/sliding door rails at home, please test the robot vacuum’s climbing capability before installation:
   ① If the doorsill/sliding door rail height <2cm, install directly;
   ② If the height is 2cm-3.5cm, an additional climbing pad is required;
   ③ If the height >3.5cm, installation is not possible.


Installation Notes:
1. Install the product on a hard surface (e.g., floorboards, tiles);
2. Do not install it in a non-dry-wet separated bathroom (to avoid internal components getting damp and causing malfunctions);
3. Install it in a space close to water supply and drainage (e.g., kitchen, balcony, dry-wet separated bathroom);
4. A three-pin power socket must be available within 1.5 meters of the product’s placement.
