3. Installation and Setup
Follow these steps to correctly install the Clean & Dirty Water Tank into your compatible Dreame robotic vacuum cleaner:
- Power Off: Before beginning, ensure your robotic vacuum cleaner is powered off and disconnected from its charging base.
- Remove Old Tank: Locate the existing water tank compartment on your vacuum cleaner. Depending on your model, this may involve lifting a top cover or opening a side panel. Carefully remove the old water tank.
- Prepare New Tank: If the new tank is empty, you may fill the clean water compartment with appropriate cleaning solution or water as per your vacuum cleaner's instructions.
- Insert New Tank: Align the new Clean & Dirty Water Tank with the compartment. Gently slide it into place until it clicks securely. Do not force the tank.
- Secure Cover: Close any covers or panels that were opened during the removal process.
- Power On: Power on your robotic vacuum cleaner. The device should recognize the new tank.

4. Operation
Once installed, the Clean & Dirty Water Tank operates in conjunction with your robotic vacuum cleaner's mopping and self-cleaning cycles. Ensure the clean water compartment is filled before initiating mopping tasks.
- Filling Clean Water: Open the designated clean water inlet (typically marked or colored differently) and fill with distilled water or a manufacturer-approved cleaning solution. Do not overfill.
- Emptying Dirty Water: After cleaning cycles, the dirty water compartment will contain wastewater. Regularly empty this compartment to prevent odors and maintain hygiene. Open the dirty water outlet and dispose of the contents.

5. Maintenance
Regular maintenance of your Clean & Dirty Water Tank is crucial for optimal performance and hygiene. These accessories are designed for easy disassembly and cleaning.
- Daily Emptying: Empty the dirty water tank after each mopping cycle to prevent bacterial growth and unpleasant odors.
- Rinsing: Rinse both the clean and dirty water compartments with fresh water after emptying.
- Deep Cleaning: Periodically, perform a deeper clean using a mild detergent and a soft brush to remove any residue or buildup. Ensure all detergent is thoroughly rinsed out.
- Drying: Allow the tank to air dry completely before reinserting it into the vacuum cleaner to prevent mold or mildew.
- Inspection: Regularly inspect the tank for any signs of wear, cracks, or damage. Replace the tank if significant damage is observed to maintain vacuum performance.

6. Troubleshooting
If you encounter issues with your Clean & Dirty Water Tank, consider the following common solutions:
- Water Leakage: Ensure the tank is correctly seated and fully inserted into the vacuum cleaner. Check for any cracks or damage on the tank itself.
- No Water Dispensing: Verify that the clean water compartment is filled. Check for any blockages in the water outlet or inlet ports.
- Unpleasant Odors: This typically indicates a need for more frequent emptying and thorough cleaning of the dirty water tank. Ensure it is completely dry before reassembly.
- Tank Not Recognized: Re-insert the tank firmly. If the issue persists, consult your robotic vacuum cleaner's main instruction manual for specific error codes or troubleshooting steps related to water tank detection.
