I’ve been meaning to write a review for this. My house is 3-level 4,800 SF of hardwood, marble and other stones. Full charge allows for about 3500 SF of space. Cordless is extremely helpful and far better than steam mop and 2 other items I’ve tried and returned. Somehow, the machine sort of guides me as I hold the handle lightly, not firmly. It seems to detect the moisture from the spray and knows the difference between rug and wood, too. It’s a smart product and ranks up there as my favorite electronic gadget along with Dyson cordless and Keurig. Encourage you to try!
