No, you must put hot water in the tank. But my previous experience with a heating tank was not very good. This system seems to work fine.

Six awesome little scrubbers!

Yes, you put your cleaning solution in a separate container in a cap that is right next to the water cap. It is all one piece, and very easy to use.

yes does ok job.

yes. i use it all the time on burber.

Yes, but I haven't used it yet.

I just bought mine a few days ago and the model # is F7429-900. Hope that helps.

no, it leaves the floor too wet and may ruin the grout. I use a mop (flat with covers that are washable) from Harmony. They are environmentally safe and reusable. You can also make your own mop covers with the blue microfiber towels from Sams (in the automotive part of the store) you simply sew the ends together and slip it on ends.
