4. Maintenance
Regular maintenance ensures the hygiene and optimal performance of your TOTO WASHLET+ system. The system incorporates several self-cleaning technologies to minimize manual cleaning.
4.1 Self-Cleaning Technologies:
- PREMIST: Before each use, the toilet bowl is misted with water to help prevent waste from adhering to the ceramic surface, making subsequent cleaning easier.
- CEFIONTECT: This ultra-smooth, ion-barrier glaze prevents particles from adhering to the porous ceramic surface, significantly reducing the buildup of mold and grime.
- EWATER+: After each use, the WASHLET wand automatically cleanses itself with EWATER+, a safe and powerful disinfectant. EWATER+ also mists the toilet bowl periodically to maintain cleanliness.

4.2 General Cleaning:
- Exterior Surfaces: Wipe down the exterior of the toilet and WASHLET seat with a soft, damp cloth and mild, non-abrasive cleaner. Avoid harsh chemicals or abrasive pads, which can damage the finish.
- Nozzle Cleaning: While the wand is self-cleaning, you can manually clean the nozzle tip if necessary. Refer to the WASHLET user guide for specific instructions on extending the wand for manual cleaning.
- Filter Cleaning: Periodically check and clean the water filter located at the water supply connection to the WASHLET. This prevents debris from affecting water flow and spray performance.
