content: I bought this on Sat., 1/13, and returned it Mon., 1/15!!!! It charged up perfectly fine, but when I went to use it, despite the "quiet" sound, I was amazed at how it was "bearing down" on the carpet!!!! It was actually slightly tough to push, due to this!!Our carpet is only a year old, in "loop" style, so I promptly returned it, as I was afraid it would "pull" at all the loops! YIKES!!!! Maybe great for regular floors, but I DID NOT find it carpet-friendly, at all!
