36. Why do I sell odor from the mop and dust
compartment?

clean the rag in time after mopping the floor.
The dust compartment may also emit odor with liquid getting inside. Please clean
the dust compartment in time after cleaning.

recharging itself？

it to return or manually move it back to the dock, F9 will not resume cleaning
either.

missed debris on the floor？
A: Clean the dust compartment if it is full; Clean the filter clogged with dust;
Clean the main brush if it is tangled with foreign matters.
