5. Operating Instructions
Once the water tank is installed, follow these steps to prepare your vacuum for mopping.
- Fill the Water Tank: Open the blue cap on the water tank (refer to Figure 3). Carefully fill the tank with clean tap water. Do not overfill. If using a cleaning solution, ensure it is compatible with your Ecovacs Deebot model and dilute according to the solution's instructions. Close the cap securely.
- Attach Mopping Pad (if applicable): If your vacuum model uses a mopping pad, attach it to the designated area on the underside of the water tank or vacuum.
- Start Cleaning: Place the vacuum cleaner back on the floor. Turn on the vacuum and select the mopping mode or a combined vacuuming and mopping mode through the app or control panel.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your water tank.
- Empty After Each Use: After each mopping cycle, remove the water tank and empty any remaining water. This prevents stagnant water and potential odor buildup.
- Rinse the Tank: Rinse the inside of the water tank with clean water. You can use a mild detergent if necessary, but ensure it is thoroughly rinsed afterward.
- Clean the Water Outlet: Periodically check the water outlet nozzles on the tank for blockages. Use a small brush or toothpick to clear any debris.
- Air Dry: Allow the water tank to air dry completely before re-installing it or storing it.
- Storage: Store the water tank in a cool, dry place away from direct sunlight when not in use for extended periods.
