I moved into a home with polished concrete floors and needed something to do touch ups on the concrete and the various rugs I have. I looked at many other cordless vacuums and after reading the reviews chose this one. It took the 16hours to charge that some have complained about, perhaps for those folks a corded one would be more to their liking.There are two settings on the vacuum one is just plain vacuum and another is suction with the rotating brush. I have found the best results is had if you clean out the debris chamber often and making sure the filters also are cleaned often.For the price this is a very usable vacuum. I park it in a closet that has a electrical and pull it out when needed. This will not replace your more strong vacuum but it will be very handy on those days when all you need is a quick pick me up.
