I was very excited to try this! I already had a similar one for my downstairs so I was looking in to another one for my upstairs and I am so glad I was able to try this one. It is amazing it completely exceeded my expectations! The set up was super easy and I loved that it mapped my whole upstairs perfectly. I have already used it quite a few times and so far it has not disappointed, it has left my carpets looking amazing! I am looking forward to having my shark for a long time and definitely recommend it to anybody looking in to purchasing one!
