environment, F9 turns make more turns and vacuums along the edges, which may
result in decreased efficiency.
13. How to reduce the noise of F9 during cleaning？
A : To optimize cleaning results, F9 features a fan motor with higher suction power,
so the noise is slightly louder than the previous products. To reduce the noise, you
can switch to a quieter Silent mode for cleaning.
14. Why does F9 make strange sounds during
cleaning?
A : When cleaning on tile or wood floor, F9 may produce a slight sound when its
bottom rubs on the floor.
F9 will clean and sweep the joins on the floor as it passes through, which may
produce a slight rattling sound.
These are all normal sounds and will not affect cleaning results.
15. What should I do if the Dreame F9 is trapped
during cleaning？
A : When cleaning, the F9 may get stuck by slippers, plastic bags and other
household clutters. Remove the clutters and put F9 back to the cleaned area close
to the interrupted point.
Please clean up clutters on the floor to prevent the robot getting stuck during
cleaning.
