I have ceramics tiles on the floor of the kitchen and bathroom and my new Bissell has done a remarkable job, restoring the grouting on tiles to the nice brown color of the grout. The steam cleaner is light and easy to manoeuvre...a good house helper! I have very dark hardwood elsewhere on the main floor and have used the steam cleaner with caution..so far so good. Please tell me if this is a good idea..sure hope so , it makes floor cleaning so much easier and better for my aged person.
