ウォシュレット is a Japanese brand name for a toilet seat with built-in bidet functions. It's essentially a high-tech toilet seat that washes your bottom with warm water, and often includes features like a heated seat, air dryer, and deodorizer. It's a very common feature in Japanese homes and public restrooms. The name ウォシュレット, a registered trademark, is so widely used that it has become a generic term for these types of toilet seats, even if they are manufactured by a different company.
