I absolutely love this Shark Ion Robot! Directions are so simple and very easy to set up. Simply snap brushes it comes with in the bottom, plug in the dock, power on the shark and let charge. Download the app and connect to wifi to schedule or start a cleaning from work or anywhere. Love this feature. I have two pups and floor gets pretty dirty. Love knowing I can come home to clean floor and not have to do more work! Definitely a must have and a must have. I definitely and highly recommend this product. Win win everytime!
