Yes, I have been using Vapor steam cleaning equipment for the last 17 years and they work fantastic in bathrooms and kitchens including tile and grout, mirrors and ovens faucets and shower stalls and on & on.
In the early 90's I set up the whole tile & grout cleaning for Sea World in Orlando for their 'uncleanable' tile and it worked great for years.
I have set up many resort properties and restaurants with this tool, many use it to clean their vent hoods and deep fryers, without any chemicals, and this allows them to do so during the day with the use of the dead time their employees have, saving a ton of money.
For us, it is great to have for cleaning or accelerating the cleaning on upholstery, especially the arms and front back where so much body oils exist. It is great for leather, protected as well as aniline to help remove the oils that can be difficult to remove, especially in restoration type cleaning. Even draperies come out very nice with this tool.
The unit BP has is a knock off of a unit that is twice the price and they work the same. It is a very good unit and fairly trouble free for the money.
It even works excellent for windows and will remove things off of glass that normal cleaning will not remove. As an example, I demoed one in Atlanta in a health club that could not get their mirrors clean, due to hair spray and deodorant sprays and so forth. The vapor steamer cleaned it very well, so much so the owner of the club bought one right then.
These tools are something all cleaners should have. Yes, they are slow in some areas and more of a detail machine, but they will help remove things that otherwise just do not seem to move the way most of us would like to have them move.
Before any one says anything, I do not make a penny if you buy one, I am just sharing my experience with them and some of the ways they work.
