I was lucky enough to receive the shark power detect power left away upright vacuum recently. I love shark products and I already have a stick shark vacuum but this one seems like it’s much more powerful. That product has the duo, clean detect and an ultra powerful hair pick up feature.  The duo, clean detect is able to sense that there is dirt and is able to adjust the speed and suction, depending on how much dirt and debris and here there is on the ground. It’s also able to clean in the direction of the mess. It has self cleaning brush rolls, which ensure that no hair gets wrapped around. This vacuum is ideal for people who shed as well as pets. Suction seems to be very good. 100% would recommend this and I love shark products. ￼
