Yes, you certainly can!
If you use a double press to turn on Wooshh it will remain on for 10 hours. A beep sound indicates that all-night mode is selected.
We recommend using the lowest volume setting on all-night mode to reduce noise exposure and increase battery life. We are aware that the cat purring sound may not last a full 10 hours, since the low frequency of the sound drains the battery faster but all other sounds should last a full 10 hours.
