Major Features

Toto MS920CEMFG#01 Washlet with Integrated Toilet G400

When we talk about the Toto G400 review, one of the most essential and critical aspects to discuss is the features of this product.

Toto is our most favorite brand, and its love for users is because of its incredible features. You won’t help to buy this fantastic product once you get to know about its features.

Sleek Design

Whenever you see a washlet, the first thing you notice about it is its design. Functionality and effectiveness matter, but style and looks come first. The futuristic design of this toilet flush looks very impressive. No matter what aesthetics you have in your bathroom, its modern design suits with every bathroom.

Its defined edges allow you to clean it easily. Moreover, the cleanliness also becomes easy because of its skirted design; this means no curves in the design.

Efficient Water Consumption

This integrated toilet comes with a bidet that makes its usage super easy and ensures efficient water usage. With the dual flush option in this toilet, you can save a lot of water, making this toilet very environmentally friendly.

Fortunately, the toilet is designed in such a way that you need extra water for flushing. You will get an automatic smooth riddance process. You can either do a partial or complete flush. Each time you flush, you can either use 0.9 gallons or 1.28 gallons, depending on the requirement.


The flushing mechanism of this Toto G400 washlet is good enough to satisfy its users. It works with a dual flush system that allows you to choose the water volume you want for flushing.

Thanks to its circular water movement, it is pretty fine to take away all the wastes and don’t allow any particles or germs to stick on the surface.

Automatic Lid Opening

As you approach near the flush, its sensors will detect you, automatically opening the lid. You will have luxurious feelings as the PreMist sprays the bowl leaving a good effect on the bowl. After you are done with your job, it will again clean itself, and the lid will close without any noise.

Self Cleaning

Cleaning the toilet flush regularly is a tedious and cumbersome task. You would be happy to have this flush, as it will do self-cleaning by using the wand. You have to set the settings of everything by using the remote control. The first thing you have to do is choose the type of cleaning you want for your flush.

Select whether you want the front to cleanse, rear cleanses, soft rear cleanse, oscillating cleanse, or a pulsating cleanse. Front cleanse especially for ladies, and this method uses soft yet large droplets for ensuring proper cleaning.

A rear cleanses is common for everyone who has been using a bidet for a long time. This cleansing is powerful and effective enough to ensure complete washing. While the soft rear cleanses is a cleansing method in which low pressure is used to cover the wider area. These all cleaning types can be combined together with pulsating or oscillating spray types.

After choosing this, now next step is to adjust the intensity and warmth of the spray; for this, you need to adjust pressure and temperature. Unlike the G500 washlet, this toilet flush has a memory function, so you can easily save the settings. Just set your preference and let the wand do its function itself.

Dual Max Flush

The warm air dryer function in the toilet helps reduce the moisture from the toilet, thus reducing the growth of germs. From the five temperature settings, you can choose the one that you want.

The dual-max flush will automatically determine the required flush volume according to the waste when you are done with the toilet. It will then do powerful flushing with the help of a 3D tornado flush.


Usually, the installation of toilets is something quite tricky, and doing it on your own self is almost impossible. Compared to G500, this flushing toilet is a bit easy to install. If you have some idea about technicalities, you can do it yourself; otherwise, you need to hire a professional person.

Installation is a one-time task, so hiring a plumber is a better option as you surely don’t want to do some wrong steps.


Obviously not the cheapest, but yes, it’s worth its price. Toto G400 is not expensive as the other models of this series, but it is neither less in price. But don’t worry, every buck you pay will surely pay you back in the form of incredible features and reduced water bills.
