I love this Shark Robot vacuum with self empty base. I was so excited to use this. There is an app to go with it. The technology on the Shark goes above and beyond, yet it’s super simple to use. The mapping allows the vacuum to clean every nook and cranny of my home without my assistance. I love that when it’s low on battery, It will dock itself so you never have to search for the vacuum or carry it back to the charger. It’s really does everything on its own, so you don’t have to do anything except admire your clean floors!
