Yes, it’s a nice high pressure jet of warm water. At least in Tokyo, toilet paper is also provided, and you can double check by wiping after. They’re definitely going in when we redo the bathrooms in our house.
This misrepresents it, at least in my disappointing experience. The jet is nowhere near powerful enough to spray off poop. You are going to be getting most of it with your fingers and the jet just helps wash it away.
I found it to work pretty well, the the only use for toilet paper being to dry off quickly. The jet spray power can often be varied. For health reasons, it is usually set to quite soft though (Washlet Syndrome).
I’ve got a BioBidet (that’s the brand name) and never once has it not fully gotten everything off. There’s a lot of varieties of bidets, you were just using a less automated style most likely.
I started using integrated bidet after the last move within US last year. The previous owners had that installed. It is great! Don't think you need to use wipes after.
Did you buy one in the states?
