This duo vacuum system has worked well so far, as I have owned it for about 1 month now. The robot does a very decent job of vacuuming up debris and cruising around the house. I do not have stairs, so I cannot give a review on that process. I will say that you have to make sure you block off your home into smaller areas, either using the provided magnetic barrier strips or by using pillows, otherwise the robot will not be able to finish cleaning the entire home. I also thought the robot would be able to digitally map out a picture of the layout of your home and possibly break down the home into zoned "areas" that could be scheduled for cleaning, but this is not possible. I really, really love the cleaning stick that can just suck up dirt or debris very quickly, although the battery life is very short. There are 2 attachments that come with it, one for upholstery and one for crevices/small spaces. There is also a secondary dock for the robot to help it charge in a large house, if need be. I definitely find this product helpful, and would recommend it to anyone interested in trying out a robot and who has enjoyed the quality of Shark products.
This vacuum combo is beyound amazing! It has deffinetly saved me time and made clean up much easier. I would deffinetly reccomend this purchase.
