This vacuum exceeded my expectations. My last Shark has lasted me years and I am so excited for this upgrade. Being cordless makes it so easy to grab and go any time of the day and the suction power is great! The auto detect feature is really cool and the vacuum feels like it's literally gliding itself and the sensors to detect walls and going under my couch are something I've never had before. When you set it on the base it sucks everything right out and the base holds a lot. I'm so obsessed I vacuum several times a week and it picks up stuff every time even if it looks clean.
