I received this product and had just vacuumed my living room. As excited as I was I wanted to see if it would find dirt my other brand missed. To my surprise it found a lot! I love this vacuum as it has a defection technology that not only adjusts its suction and roller based on the flooring type but also by if it finds more dirt. It has a light that will turn purple when it’s auto detecting and white when all the hidden dirt is found. It found dirt my other vacuum couldn’t dream of finding. I am now a shark fan!
