- Attach to Vacuum: Ensure the tank is correctly installed on the vacuum cleaner as described in the 'Setup and Installation' section.

Maintenance and Care
Regular maintenance of the clean water tank is essential for hygiene and longevity.
- Empty After Each Use: After each cleaning session, empty any remaining clean water from the tank. Do not store water in the tank for extended periods.
- Rinse Thoroughly: Rinse the inside of the tank with clean water to remove any residue from cleaning solutions.
- Air Dry: Allow the tank to air dry completely before reattaching it to the vacuum or storing it. This prevents mold and mildew growth.
- Check Seals: Periodically inspect the rubber seals around the fill cap and connection points for wear or damage. Replace if necessary to prevent leaks.
