I've used less advanced versions for a few years. The quality varies; the most recent one we put in is pretty horrible to use (but better than nothing). I've always wanted to try a real Toto, especially with the drying feature.
A word of warning for female users:
> Habitual use of bidet toilets aggravates vaginal microflora, either by depriving normal microflora or facilitating opportunistic infection of fecal bacteria and other microorganisms.
> Over washing the anus risks removing the sebum, which lubricates the surface. There have been reports of problems caused by over drying of peripheral areas
> This leaves the body vulnerable to dermatitis and possibly invasion of staphylococcus aureus bacteria.
> Of the 292 [hospital] toilet seats sampled, warm-water nozzles of 254 (86.9%) were found to be contaminated by one or more of the following organisms
I'm not convinced this is actual sanitation.
Edit: I should say, I know due to physical and diet circumstances taking a shit might leave you with more or less of a mess that could be uncomfortable or inconvenient - but I don't think unqualified praise for bidet use, suggesting bidets as a superior lifestyle choice, etc is good.
Seems like some of those problems could be partially addressed. Such as a retractable metal nozzle that is sanitized with heat or steam after use, not using warm water, reducing spray velocity, adjusting angle of spray, limiting spray time and throttling subsequent sprays, etc.
Interesting. I've never been a fan of the warm-water ones myself. I wonder how it compares to (only using) toilet paper with regards to dermatitis, I find that toilet paper can really cause issues sometimes and bidets are more helpful in that regard.
The drying is awful in my Toto, it's not enough air pressure. It'd take 20+ min to dry completely. It's nothing like those hand dryers in public bathrooms.
