Suction power is really impressive. Laser green light discovers imperfectness of your flooring to fine details and this is not always dust! There are at lest three problems with this device though:
1. battery life is not the greatest
2. manoeuvring in small spaces when you want to clean under your beds is too difficult if not possible on some occasions
3. charging pod could be a bit more robust and stick to the wall tightly. i am wondering what if you decided to move your charging pod - is it even possible to access wall mounting screws without braking the plastic? 
All accessories should be coming in some kind of organiser - ready for a shelf or wall hanged.
Fluffy/soft carpets with  air-no-permeable lining are difficult to clean as carpet nozzle  stops working. 
Changing accessories could be easier - pressing the button so away from the body to release the accessory from the pipe is extremely impractical.
