I was unsure how a single cloth could effectively clean my floors. We are having a brutal winter with salt and mud being tracked into the house by the kids and dog. The ability to run the thing on a daily basis is great. We also have an older Roomba that we run on a schedule and the combo of the two is fantastic. The combination of the two leave our dark wood floors in great shape. I love the quietness of the unit. We use it with Vim wood floors and have great results. No filmy residue or streaks. Very happy that I pulled the trigger on the purchase.
