I’ve had an iRobot (about 5 yrs old) which I liked but this is on another cleaning level! I like to not even worry about changing the bag after 6 months & I vacuum 3x a week with this Samsung! It’s incredibly accurate & you can where it goes with the camera & it will recharge then finish the job! And did I mention how flippin’ quiet it is??!! You only hear the voice letting you know it’s starting or if there is an issue—I can’t say enough about how amazing this is!!!
