Quick clean mode allows you to clean an area 30% faster by focusing on the open area only. It will skip the perimeter clean and will not focus on areas around chair legs or furniture legs. This is available on 380 series Braavas.
To activate Quick Clean, hold either the SWEEP or MOP button for 3 seconds then release. You will hear a single beep followed by the "start cleaning" song.
Braava typically cleans the same total area as the standard detailed cleaning mode, but will skip detailed cleaning around furniture and some walls to save time.
