When I first got this I was very skeptical thinking no way is this going to work but after I used it I was very shocked & surprised. Love the fact that it’s for hard wood floors and carpet. Very easy to operate. Love the fact that it has an app you can use ..just makes me lazier..just kidding. It’s definitely one of the best..that I’ve ever used.  This is great for pet owners…picks up hair great. Shark products never seem to disappoint me. Would definitely recommend to others you will not be disappointed.
