Bidets are primarily used to wash and clean the genitalia, perineum, inner buttocks, and anus. Some bidets have a vertical jet intended to give easy access for washing and rinsing the perineum and anal area. The traditional separate bidet is like a wash-basin, and can be used for many other purposes such as washing feet.
A spray bidet is a hand-held triggered nozzle which delivers a spray of water to assist in anal cleaning and cleaning the genitals after defecation and urination. In contrast to a bidet that is integrated with the toilet, a bidet shower has to be held by the hands, and cleaning does not take place automatically. Bidet showers are common in countries where water is considered essential for anal cleansing.
Drawbacks include the possibility of wetting a user's clothing if used carelessly. In addition, a user must be reasonably mobile and flexible to use a hand-held spray bidet.
There is a better way to clean by using Haoluu’s bidets, which built into the toilet, bidet seats, and attachable units that slip under a standard seat. When the word "bidet" is used nowadays, it's usually in reference to one of these innovations rather than the traditional fixture.
