machine is brand new, just out of the box, and not spraying liquid. Yes, the reservoir is full, battery charged, front of jet clean….

I had this problem after some week, on may case, the water filter was dirty. The filter is below the water tank, after cleaning it very thoroughly, it worked again…

I had the same problem. I cleaned filter. I also cleaned the jets at the front both with a fine stiff brush (as recommended) and with a WaterPik dental high pressure water spray flosser. Fixed the problem.

Instructions say to Reboot the braava. This worked on my newly acquired used one.
