TOTO, a global leader in bathroom technology, has developed a series of smart features that go beyond what many expect from a traditional toilet. These features are designed as a smart solution to solve bathroom frustrations that homeowners face regularly.

This article explores how TOTO’s premium toilet innovations, such as warm-water cleansing, self-cleaning mechanisms, powerful flush systems, and bacteria-resistant materials, work together to improve the everyday experience. As a homeowner upgrading your space or a professional selecting fixtures for clients, understanding these features will help you make more informed decisions and achieve a bathroom that is not only modern, but also easier to live with.

PREMIST

A thin film of water coats the toilet bowl before use, preventing waste from sticking and making it easier to wash away.

PREMIST is an automatic function that sprays a fine mist of water onto the toilet bowl before each use. Due to its hydrophilic nature, water spreads evenly across the surface instead of forming droplets. This helps waste slide off more easily. The effect is enhanced by TOTO’s CEFIONTECT glaze, which makes the ceramic ultra-smooth.

CEFIONTECT

It's an ultra-smooth, advanced glaze that coats the surface of ceramic toilets to keep TOTO Toilets cleaner for longer.

CEFIONTECT is TOTO’s proprietary ultra-smooth ceramic glaze that forms a microscopic barrier over the toilet bowl’s surface. It’s engineered to prevent waste, mould, and bacteria from sticking, making cleaning easier and improving long-term hygiene.

Eliminates microscopic gaps where waste hides

Unlike standard ceramic finishes, CEFIONTECT creates an extremely smooth, ionised barrier on the toilet bowl’s surface, measuring just nanometers thick. This glaze fills in microscopic gaps and pores in traditional ceramics, making the surface repellent to waste, mould, and lime scale buildup. In other words, waste particles, dirt, and bacteria have nothing to cling to.

What makes CEFIONTECT more durable?

TOTO fuses glass-like particles into the glaze at extremely high temperatures, forming a strong, long-lasting surface layer that won’t peel or degrade over time. This process makes CEFIONTECT significantly more durable than standard ceramic coatings.

Water has strong attraction to CEFIONTECT

Unlike water-repellent surfaces, CEFIONTECT is hydrophilic, meaning it attracts water and allows it to spread evenly across the bowl. This creates a smooth, continuous film that helps water rinse away waste more efficiently. The even coverage reduces the need for scrubbing, supports cleaner flushes, and enhances the performance of rimless toilet designs that rely on consistent water flow.

RIMLESS DESIGN

TOTO’s smart toilets feature a rimless design, removing the inner rim found in traditional toilets. 

This eliminates hard-to-reach areas where dirt and bacteria usually build up, making the bowl easier to clean and more hygienic overall.

TOTO’s rimless bowl design complements the functions of PREMIST and CEFIONTECT to support a higher standard of hygiene. While PREMIST ensures that waste is less likely to adhere and CEFIONTECT provides an ultra-smooth, non-porous surface, the rimless structure eliminates areas where residue and bacteria typically accumulate. Together, these features reflect TOTO’s commitment to cleanliness, ease of maintenance, and advanced toilet engineering.

These features reflect TOTO’s ongoing commitment to innovation and user-focused design, creating a world-class bathroom experience that balances comfort with advanced technology. This attention to detail continues through to the cleansing process, where hygiene is prioritised at every step.

AUTOMATIC OPEN AND CLOSE LID

The automatic and open-close lid function happens when the user approaches and closes it after use. Its hands-free operation promotes hygiene by minimising contact with surfaces, while also offering added convenience and a sense of hospitality. 

It is made possible by a built-in sensor that detects the user’s presence and movement, allowing the lid to open and close without manual contact.

HEATED SEAT

The seat is gently warmed using an integrated heating element built into the seat structure, providing comfort during use, particularly in cold weather. The temperature can be adjusted or turned off completely through the control panel or remote, giving the users full control over their preferred settings. TOTO’s design ensures even heat distribution across the seat surface for a consistently comfortable experience.

How the Cleansing Process and Bidet Function Work in TOTO Smart Toilets

The cleansing process is the heart of TOTO’s smart toilet technology. Through Clean Synergy, each component, from water delivery to sanitation, works in harmony to deliver a precise, hygienic, and fully automated experience. This unified system reflects TOTO’s commitment to redefining personal care and setting the global benchmark for bathroom innovation.

The next feature that makes Clean Synergy remarkable is TOTO’s EWATER+® system. An automatic self-cleaning technology that uses electrolysed water to sanitise the bowl and the washing wand.

SELF-CLEANING NOZZLE AND EWATER+ 

Electrolysed water might sound high-tech, but it’s essentially water that’s been given a mild charge to turn it into a safe, gentle cleaning agent (the same kind of natural sanitiser used in some food preparation and hospitals). TOTO built this feature to keep the toilet fresh and microbe-free without requiring any chemicals from you.

How EWATER+ Works

After each flush, the toilet releases a mist of EWATER+ into the bowl, coating the surfaces that might have remaining bacteria or waste matter. This water, charged with a bit of chlorine from the natural salt in tap water, helps break down and neutralize bacteria.

According to TOTO, after each use EWATER+ mists the bowl, reducing the need for harsh cleaning chemicals by killing germs and preventing residue buildup . In other words, the toilet is essentially self-disinfecting after every flush.

EWATER+ Taking Care of Its Wand (The Bidet Nozzle)

Before and after each use, the cleansing wand automatically washes itself with a spray of water or EWATER+ . The wand is even designed to retract into a protective sleeve or behind a door when not in use, so it stays shielded from splash-back. With EWATER+, this self-cleaning extends to sanitising the wand’s tip and even flushing out its inner channels. TOTO engineers went as far as using a high-quality, waste-resistant resin for the wand, so it’s less prone to stains to begin with, and they mount the wand above the bowl’s water line to keep it in a “dry zone” where it’s unlikely to contact waste.

EWATER+ Offers Convenience and Reassurance to its Users

EWATER+ removes the need to constantly scrub under the rim or rely on heavy-duty cleaning products, this technology takes care of the routine maintenance for you. By misting the bowl and sanitising the wand automatically, EWATER+ helps the toilet stay visibly clean and hygienic with minimal effort. Over time, this self-cleaning cycle helps preserve the pristine finish of the bowl, making it especially appealing for homeowners who value long-term performance.

Because EWATER+ uses only a mild electrical charge to convert ordinary tap water into a safe cleaning agent, it’s also an eco-friendly, chemical-free solution that supports healthier living. And when combined with the PREMIST function, it forms a smart, automatic system that works before and after each use, one prevents waste from sticking, the other keeps surfaces sanitised. This seamless approach reflects TOTO’s broader commitment to comfort, hygiene, and intelligent design. And it sets the stage perfectly for another standout feature: a flushing system that’s just as efficient and thoughtfully engineered.

Warm-Water Cleansing with Air-In Wonder-Wave Technology

The Air-in Wonder Wave Technology is a standout feature of the warm-water bidet system. This innovation works by infusing air into the cleansing water stream, causing the water to form larger, air-infused water droplets for washing. These droplets (around 30% bigger than usual) create a soothing, aerated cleansing spray that stays gentle on your skin while still rinsing you thoroughly clean. As part of the TOTO WASHLET system, the water is heated instantly and continuously, so the warm water toilet wash always stays at a comfortable temperature, ensuring consistent comfort throughout the wash.

Adjustable Water Pressure

Allows users to control the strength of the cleansing spray, ensuring a comfortable and personalised wash based on individual preference.

Using a remote control or side panel (depending on the model), you can easily choose how strong or gentle you’d like the spray to be. Most TOTO WASHLET units offer preset levels, from low to high, so each user can find a pressure that suits their preference. A lighter setting is ideal for everyday comfort or sensitive skin, while a stronger spray provides a more targeted, powerful cleanse. And because it still uses Air-In Wonder-Wave technology, even the higher-pressure modes remain smooth and comfortable. This level of control makes the bidet with warm water suitable for every member of the household, from children to older adults.

Personalised Cleansing Modes

TOTO’s commitment to elevate user experience, adjustable water pressure also comes in personalised cleansing modes, making WASHLET models come with multiple cleansing modes that can be tailored to each user.

Using a remote control or a side panel (depending on the unit), you can easily select the type of wash that suits you best, from a focused stream to a softer, broader spray. These adjustments aren’t just for comfort; they make personal hygiene more accessible and reliable, especially for people with sensitive skin, mobility challenges, or those simply wanting a more customised experience.

Here’s a breakdown of the four main spray modes available on most TOTO WASHLET models:

  • Rear Spray: A standard cleansing mode that delivers a steady, targeted spray to the rear area. It uses firm but comfortable pressure for a thorough clean and is ideal for regular, everyday use.

  • Rear Soft Spray: This setting offers a gentler alternative to the standard rear wash, delivering lower water pressure with a slightly wider coverage. It’s designed for users who prefer a milder clean, making it ideal for those with sensitive skin, discomfort, or conditions like haemorrhoids. The softer spray helps maintain hygiene while reducing irritation. It’s particularly useful for older users, people with limited mobility, or those recovering from childbirth, where a more delicate wash can make daily routines more manageable and comfortable.

  • Front Spray: A forward-facing wash designed primarily for feminine hygiene. It uses large, soft droplets that feel comfortable and provide a refreshing cleanse for the front area. Many women prefer this mode for its balance of coverage and delicacy.

  • Wide Front Spray: This setting delivers a broad, low-pressure spray, creating a gentle wash that feels more like a soft curtain of warm water. It’s particularly appreciated for monthly hygiene, postpartum care, or simply when a full, calming rinse is preferred.

Apart from spray type, many TOTO models also let users activate an oscillating or pulsating spray motion. These functions offer additional flexibility, so the wash can be tailored to different preferences or needs throughout the day. 

These thoughtful controls make TOTO accessible and comfortable for everyone in the home, from young children to elderly users, offering the right level of care, control, and confidence for every stage of life.

Warm air drying gently dries the cleansed area using adjustable air temperature, providing a hands-free and hygienic alternative to toilet paper.

Odour Control with TOTO’s Built-In Deodoriser and Carbon Filter System

To maintain a fresh and pleasant environment in the bathroom, TOTO smart toilets are equipped with an automatic deodoriser system. This feature activates as soon as the user sits down, drawing air from the bowl through a high-efficiency carbon filter that neutralises unpleasant odours at the source.

The deodoriser works continuously during use, ensuring discreet yet effective odour control without the need for air fresheners or chemical sprays. The carbon filter, known for its strong absorption properties, traps and breaks down odour particles before they can escape into the room. This not only improves air quality but also contributes to a more hygienic and comfortable bathroom experience.

TOTO’s deodoriser eliminating odours

While no system can eliminate 100% of all odours, TOTO’s carbon filter technology significantly reduces and neutralises them during use.

Replacing the Carbon Filter

A carbon filter is a purification component that uses activated carbon, a highly porous form of carbon, to capture and neutralise airborne particles, gases, and odours. It’s commonly used in air purifiers, water filters, and advanced toilet systems like TOTO’s for its exceptional ability to trap contaminants.

The carbon filter in TOTO’s deodoriser system is a key component designed to neutralise bathroom odours by absorbing and breaking down airborne particles during and after use. Positioned within the toilet’s ventilation system, it draws air from the bowl, filters it through activated carbon, and releases it back into the room, clean and odour-free.

Carbon is used because of its adsorptive properties.

Carbon attracts and holds molecules on its surface. When carbon is “activated” (processed to create millions of tiny pores), it gains a massive surface area; just one gram of activated carbon can have over 500 square meters of surface area. This allows it to effectively trap odour molecules as air passes through, making it an ideal material for maintaining a clean, odour-free environment in enclosed spaces like the bathroom.

Few Questions Related to TOTO’s Carbon Filter

1. Replacement and Maintenance

To maintain optimal performance, the carbon filter should be replaced approximately every 6 to 12 months, depending on usage and model. Some models may feature an indicator or alert system when the filter needs attention. Regular replacement ensures continued effectiveness in odour control.

2. Can You Add a Fragrance or Scent?

TOTO’s system is designed strictly for neutralising odours, not for releasing scents. The carbon filter does not support the addition of fragrances or deodorising agents, as doing so could damage the filtration process or reduce its efficiency.

3. Is the Deodoriser Automatic?

Yes. The deodoriser function, including the carbon filter operation, is fully automatic. It activates when a user is seated and runs for a short period after use, with no need for manual activation.

DynaMax Tornado Flush: Powerful, Quiet, and Water-Saving Performance

Traditional toilets often use a combination of a siphon jet (a hole at the bottom of the bowl) and rim holes to rinse, which can split the flushing power. 

DynaMax Tornado Flush takes a different, more efficient approach: it sends 100% of the flush water through strategically designed nozzles around the rim, harnessing the full volume for both cleaning the bowl and evacuating waste . As the water streams in, it creates a vigorous 360-degree whirlpool that reaches every spot in the bowl. 

The DynaMax Tornado Flush is incredibly effective at waste removal; it generates a pushing force that propels waste out swiftly, reducing the risk of clogs, particularly valuable in households with older plumbing or higher usage. 

TOTO’s high-efficiency flushing system delivers powerful performance while using as little as 3.8 litres per flush, significantly lower than the 6-litre standard found in many traditional toilets. According to usage data, this equates to around 22,192 litres of water per year for a typical household of 2–3 people, compared to 35,040 litres for standard toilets. That’s a 36% reduction in annual water use, translating to noticeable savings on your water bill, about $266.30 per year in operating costs versus $420.48 with a conventional toilet.

Lastly, After the flush, EWATER+ is sprayed again inside the bowl to sanitise the ceramic surface. 


The genius of TOTO’s approach is how these features work in harmony. TOTO’s toilets have an integrated system where each element, water temperature, spray style, bowl coating, pre-mist, flush, and design, complements the others. The end result is a toilet that keeps itself cleaner, keeps you cleaner, and does so with less effort and resources. Homeowners who invest in these luxury features find that their bathrooms stay fresher and require less manual cleaning, all while offering a spa-like comfort every day. Bathroom renovation customers often cite the WASHLET as their favourite upgrade.

In essence, TOTO has reimagined what a toilet can be: it’s a welcoming warm seat on a cold morning, a gentle and effective bidet cleansing at the push of a button, and a self-maintaining appliance that quietly handles the dirty work for you. This blend of luxury and practicality means you’re not only indulging in comfort but also investing in a fixture that stays beautiful and performs reliably for years. From comfort to hygiene to ease of cleaning, each premium feature of TOTO toilets contributes to an overall experience of everyday luxury – truly a “clean synergy” that transforms the bathroom into a place of wellbeing and delight.
