I keep a very clean home and I couldn’t wait to try this on my main floor since it’s mostly hardwood and area rugs. I had just cleaned so I didn’t expect much in the tray.  I also have a dog, and I couldn’t believe my eyes when I emptied the tray!!! It picked up SO much stuff that my eyes couldn’t see!!! It also gets into and under most everything my regular vacuum can’t! This vacuum is AMAZING and easy to set up as well as very through in my home.  I absolutely LOVE IT!!
