what an interesting site. bidets are awkward for westerners, but I see it catching on in hotels nationwide. apparently moist-towelettes aren't enough. I saw a commercial recently that showed a girl wiping a muddy dog with dry paper, then wiping it with a wet paper cloth. the wet paper cloth (moistened toilet paper) worked much better, and showed how inefficient dry paper is.
I'd like to make the switch to a more "efficient" cleaning system like a bidet, but I rent my apartment, and there isn't enough room for a seperate unit. maybe these all-in-one units will have to do.
