I bought the Shark vacuum/steamer and couldn't wait to use it. However, I wasn't so thrilled with the results. I loved the idea of having an all in one tool to do my floor cleaning, but it just didn't work for me. I used the vacuum part first, which made a loud high pitched noise. Might not sound like a big deal, until you use it and it drives you crazy. Plus, it didn't vacuum up the dirt or dust along the edge of walls. Then I tried the mop part, which I also wasn't too fond of because the steam wasn't constant and it was hard to mop in tight places. I have since returned the mop and bought the Shark Steam Mop, the one in the white box which is Shark's best one because it comes with lots of accessories. Anyways, I LOVE it! I can mop in tighter areas and I can choose how much steam I want to use. I'm not sure if there will ever be a great two in one product, but for now I'll stick with Shark's steam mop and a broom.
Oh, and you can use it on all hard floors...linoleum, tile, sealed hardwood floors, etc. I have tile and hardwood floors and it works great! I love that my floors don't get sticky from using other cleaners to clean my floor and I can use it everywhere in my house (since all the floors in my house are hard surfaces)! And, although no chemicals are being used, my house smells clean afterwards. My son and a huge accident at night in his bed (he was sick and he had throw up and diarrhea all over his bed). Some must have gotten on the floor because after cleaning the room it still smelled horrible until I pulled out the steam mop. I LOVE it!
