I've used both a Toto washlet and a cheap bidet toilet attachment. While I loved the Toto for all of it's cool features, the water pressure (which is powered by an electric pump) just wasn't there and didn't do a great job cleaning. The cheap attachment on my home toilet is powered solely by water pressure and that thing leaves me sparkling clean!
Hmm, was it an old toto? I got one a few years ago, and it's powerful enough that it needs an injection warning label on the side. Turn it past the third setting, and you start coughing up water, haha.
