When it works, vac or mop it does a great job. Amazed what it picks up. What I am not happy with is the map. Sometimes it does the job completely. Mostly I ask for the whole house and it stops after 30 minutes,  maybe 2 rooms. So I start it up again, then it seems to finish. Another is that it takes the whole day to get the job done. It has to dock and recharge. It takes a long time to do so. It seems quiet enough to do its job while I am sleeping. I work odd hours so I sleep odd hours. If only it would do the whole house and in the time it tells me,  then it would be perfect.
