Don't bother with the Shark - it leaves streaks & is poorly made. Get the Haan Slim & Light floor steamer SI-35 - purchase on Amazon - i love it! I also bought the Haan hand held steamer which works great as well. You won't be disappointed.

I have a shark steam mop and I love it.. so does my daughter... It does not leave any streaks. I have had it about 4 years and still works flawlessly...I add a little bit of vinegar to the water and it steams like a tea kettle!..

Eureka enviro is the best cleaner according to this reviewer.
Shark is the worst.
Shark doesn't get hot enough to kill germs.

I've had the enviro steamer for 10 years. It cleans well and has been very durable
