First robotic vacuum. Easy to install right out of the box. Used my Smart Things App to program. Installation did say it was charged but was not. I had to wait for full charge. It stared up right after and I was amazed. It set a floor plan and worked around furniture. The cleaning is precise. It moves slowly and picks up all particles. I  did have issues with it docking properly on several occasions. Overall I thinks this is another great product from Samsung.
