    Why Buy From Clear Moon Bidets

    TOTO's AQUIA®IV WASHLET®+ series provides Toto's popular C5 Washlet® bidet toilet seat paired with its beautiful Aquia®IV toilet. Unlike most bidet toilet seat and toilet combinations, the AQUIA®IV WASHLET®+ series is designed so that all hoses and connections are concealed. No need to stress about whether the Washlet will fit your toilet. You get a perfect Washlet fit and a beautiful modern skirted toilet that offers clean lines, minimal flourishes and geometric precision. This style is elegant and smooth, concealing the trapway, and features a base that is easy to clean and maintain.

    What sets Toto apart from all other brands is their ewater+® technology.  By electrolysing the water and using the Premist™ feature, which sprays the bowl with water before each use, the AQUIA®IV WASHLET®+ C5 leaves no build-up and the toilet bowl stays much cleaner. This eliminates the need for harsh cleaning chemicals, that are harmful to us and the environment when they are introduced into our water systems. TOTO's ewater+® is completely safe yet powerful. TOTO's ewater+® and Premist™ are truly ground-breaking when it comes to bidet advancements. 


    TOTO’s extraordinarily smooth CEFIONTECT® glaze prevents particulates from adhering to porous, ceramic surfaces. The ion-barrier in CEFIONTECT keeps everything cleaner, longer. Less cleaning means fewer chemicals in the environment and less water and energy used for cleaning.

    The DYNAMAX TORNADO FLUSH® features two powerful nozzles that create a centrifugal, cyclonic rinsing action which reduces waste buildup, reaches every spot on the toilet bowl and keeps the bowl cleaner.  DYNAMAX TORNADO FLUSH® makes it possible to evacuate and clean with a single flush despite using a lower volume of water. This high-efficiency system is more effective in one flush than most toilets are with multiple flushes. The modern hole-free rim design means that it performs more consistently and is easy to clean. 

    The C5 Washlet® is a great example of TOTO's unrivalled smart and sustainable design. The TOTO C5 WASHLET® has most of the same features as its cousins, the S500e and S550e

    The TOTO AQUIA® IV - WASHLET®+ C5 Two-Piece Toilet features a soft warm front and rear wash, a tank hot water system stored in the rear of the seat and a deodorizer for odor elimination. The tank supplies up to a minute of adjustable temperature warm water, while the warm air dryer is adjustable in air temperature. This system differs from the S550e and S500e models, which have on-demand hot water systems.

    This model features TOTO's NEW Aquia®IV bowl shape. This new bowl is larger and provides a better flush than previous Aquia®IV models.
