I have black glossy tile floors with gray marbling in my 1000 square meter apartment. Feet, except for the cream fireplace. You can see every streak and speck of dust on it. My son gave me this for Christmas and I used it today. So great! I wash my house every other day and did it the day before Christmas. Doesn't matter! He picked up dirt I didn't know about. He washed my whole house with half a tank of water. The cord is a great length in my house as I only had to switch outlets between rooms. I will be getting more pads to switch pads between rooms as the last one I did is a bit striped. It took me half the time and energy to use than my microfiber mop and spray bottle. I'm disabled and this was a lot easier without having to clean.
