I received my Shark AI Ultra 2-in-1 Robot vacuum the other day. I never thought that I’d want a robot vacuum, I didn’t think they would clean well at all. Since I received this vacuum I have changed my mind considerably. This thing makes me very happy. It was very easy to set up,(most things like this would have you tearing your hair out), it runs quietly, the suction is excellent. It vacuums my rugs and mops my hardwood floors. It doesn’t have to be emptied for 60 days, on normal vacuuming. It saves a lot of time in my housework. Although I haven’t been able to make my cat ride it yet. I am a very happy with this.
