Trust me, you need to try this! 

The experience of a luxury intelligent toilet. Manufacturer Toto is keen to show how its "intelligent" washlet system can be good for the environment and improve people's experience in the bathroom.

How smart is the toilet?

"You walk up to it and it opens up, and when you leave it closes and flushes automatically," Toto spokeswoman Lenora Campos said.

It also eliminates the need for toilet paper.

"It scans and delivers warm aerated water" to the user, she said. "It washes and then dries you. We can be clean without paper products."

After usage, the toilet cleans and sanitizes itself with electrolyzed water. And because of its coating of titanium dioxide and zirconium, nothing sticks to the bowl.

That means it can go for a year without cleaning, avoiding the use of environmentally harmful chemicals, Toto says.

None of this is new to many Japanese or visitors to the country—Campos said about 70 percent of Japanese homes use this kind of washlet system, but that the idea is gaining ground in other countries.

Toto has been selling the Neorest model in the US and Europe and at in Las Vegas introduced a newer version—a wall-hung toilet which takes up less space with its tank and drain in the wall, and is even more water-efficient.

This new model is being introduced in Europe this year with plans for the US market in 2017.

One thing that may be hard to digest for users is the price: a list price of $10,000 for the original Neorest, and possibly more for the new model.

Toto USA president William Strang said its customers are the best promoters of the intelligent toilet.

"Once they test-drive this, they don't want to go back," he said.
