Purchased this unit locally in central NJ. This unit heats to steam in about 30 seconds, it produces a lot of steam and cuts through black paw prints on tile floor with ease. I have used the grout brush twice now to keep up with tracked in dirt trapped in the grout lines and the grout is restored to its original color. As far as the drool is concerned, the mop takes care of dried on drool in one or two passes. Dirt is trapped in the microfiber mop heads which can be tossed in the wash or hand washed. The mop is lightweight, and requires only a little water to produce a lot of steam.
