Had an old unit that died after 10 yrs. Got this and it works great on my title floors. With the larger fill tank, I'm able to do the whole house on 1 tank, my old unit I'd have to fill 3 times. The brushes are bigger on the new unit making for better cleaning and the suction is much better than the old unit leaving almost no liquid on the floor. I would have given 5 stars, but the suction part that fits over the brushes is hard to take off and put on for cleaning. You have to pull up on a plastic tab to release it which I fear will break in the future. My old unit had slide tabs to release it, a much better design. Other than that, I'm very pleased with the unit.
