I have been using this robot regularly for almost 3 months now and couldn't be happier. We had one of the very first Roomba models and did a lot of research before deciding on our McDream. This robot is definitely quieter than our previous Roomba, the suction power is good and I liked the mapping and mopping functions. It requires regular maintenance depending on how often you use it (wiping the sensors to keep them tangle-free and brushing out my very long hair). There were a couple of times that he got tangled or stuck and we have a spot where there's an exit to the next room and sometimes he makes it in but then he can't get out. Overall I save time when I have a schedule and I like being able to select a specific room if that room needs more maintenance. No real complaints!
