The shark IQ XL is awesome! You can connect it to your phone and have it clean when you want to. It has a dumping station for the robot to dump the particles which are contained inside. You only have to manually dump it once every 30 days and that's word from the manufacturer. And you can also connect it to your Alexa. It works very well pet hair. I have to give this robot a five-star review I really love it so much!!
