Advanced Self-Cleaning Technologies: What Makes WASHLET+ Better for You and the Environment?
If you’re looking for a more sustainable, low-maintenance, and healthier way to keep your bathroom clean, WASHLET+ by TOTO delivers on all fronts. While many people are drawn to WASHLET+ for its warm-water cleansing and integrated design, the real breakthrough lies in its ability to maintain a fresh, clean toilet without the need for chemical cleaners or abrasive products.

This self-cleaning system isn’t just about convenience. It’s a smarter, more eco-friendly approach to bathroom cleanliness that protects your health, simplifies your routine, and reduces environmental impact. Here’s how WASHLET+ makes effortless, advanced toilet cleaning possible, automatically.
Why Advanced Cleaning Technologies Matter
Many bathroom cleaners do a good job removing stains and killing germs, but they come with serious tradeoffs — strong fumes, skin or eye irritation, and chemical runoff that can harm the environment.
These cleaners often go hand in hand with high toilet paper usage, which adds to environmental impact. The average American uses over 140 rolls of toilet paper per year, contributing to deforestation, high water consumption in manufacturing, and landfill waste.
WASHLET+ provides a sustainable alternative to both of these problems, helping users maintain an eco-friendly bathroom that’s cleaner, healthier, and easier to maintain, with less effort and zero harsh commercial chemicals.
What Is WASHLET+?
TOTO’s WASHLET bidet seats are celebrated for their warm-water cleansing, self-cleaning wand, and advanced features like PREMIST® and EWATER+®.
WASHLET+ builds on this innovation by integrating the WASHLET seat with a specially designed TOTO toilet, creating a streamlined system that conceals cords and hoses for an elegant, seamless look. This integration also enables users to enjoy additional technologies built into the TOTO toilet itself — including TORNADO FLUSH®, CEFIONTECT®, and RIMLESS DESIGN — for a bowl that stays fresher and visibly cleaner with every flush.

EWATER+®: A Powerful Water-Based Cleaning Technology with No Added Chemicals
One of the most innovative features of WASHLET+ is EWATER+® — a sustainable advanced cleaning technology that uses electrolysis to transform tap water into a mild cleaning solution.
By activating trace minerals naturally present in ordinary tap water, EWATER+ creates electrolyzed water — a low-concentration form of sodium hypochlorite that effectively breaks down waste and residue. It’s similar to what’s found in diluted bleach but produced in very small amounts and applied with precision.
EWATER+ is automatically sprayed on the wand — inside and out — before and after each use, as well as inside the bowl after every use and at scheduled intervals throughout the day. It helps reduce visible buildup and supports cleaner surfaces without relying on added fragrances, dyes, or harsh chemical cleaners. After use, EWATER+ naturally reverts to its original tap water state in approximately two hours.
Benefits of EWATER+ include:
- A more sustainable approach to everyday toilet cleaning
- Reduced need for bleach-based and chemical bowl cleaners
- Helps maintain cleaner surfaces between manual cleanings
- Compatible with septic systems and environmentally conscious households
Because it’s generated on demand, used automatically, and returns safely to water, EWATER+ offers a more thoughtful alternative to traditional cleaning products, making it easier to keep your WASHLET+ bidet toilet fresh and clean without added steps or environmental tradeoffs.
PREMIST® + CEFIONTECT®: Designed to Resist Waste Naturally
WASHLET+ bidet toilets also feature PREMIST, a pre-flush misting system that sprays the bowl before each use. This thin layer of tap water helps reduce waste’s sticking to the ceramic surface.
PREMIST is most effective on the company’s CEFIONTECT® glaze — a patented, ultra-smooth ceramic finish that resists grime, stains, and bacteria. Together, they form a powerful first line of defense that limits residue buildup and keeps the bowl cleaner and fresher with every flush.
By preventing waste from sticking in the first place, these features reduce the need for repeated scrubbing or chemical stain removers.
TORNADO FLUSH® + Rimless Design: Better Cleaning with Less Water
The WASHLET+ bidet toilet system also includes the company’s TORNADO FLUSH — a high-efficiency, cyclonic flush that uses less water while cleaning more thoroughly than traditional toilets. Its powerful vortex action rinses the bowl from all sides, sweeping waste away in one smooth motion.

Pair this with the TOTO rimless bowl design, and there’s no place for waste or grime to hide. The open, seamless contour allows water to reach every surface. No more trapped residue under the rim.
Because the bowl stays cleaner after every use, there’s less need to use abrasive brushes or harsh cleansers.
Reducing Toilet Paper, Reducing Waste
In addition to reducing commercial chemical cleaners, WASHLET+ bidet toilets dramatically cut down on toilet paper use. Their unlimited, warm-aerated water stream provides thorough, comfortable personal cleansing, replacing the need for repeated wiping. Many users find they use 80–90% less toilet paper after switching.
This shift isn’t just better for comfort, it’s better for the planet:
- Reduces deforestation and paper waste
- Saves water and energy used in manufacturing toilet paper
- Minimizes clogs and plumbing maintenance
- Reduces your household’s environmental footprint
Together with commercial chemical free toilet cleaning, WASHLET+ supports a more eco-friendly bathroom that aligns with modern sustainability goals.
