This little robot is the best thing to have ever blessed my home! Setting up the device was a breeze. It took just a couple of minutes to set up on the app. I have 4 dogs and so dog hair and dirt tracks are a constant in my house. Having the mop and vacuum option in one is so convenient to clean their messes. Robot is a bit loud, but is what I expected from a device with functions that it has. Battery life is always at 50% after mop/vaccing the entire living room and kitchen (it’s a lot of open square footage.)
