Suction settings

Owning my robot for about a week now. I was playing with different suction settings  on my X40 Ultra and the only thing I can hear is the very silent mode. I tried different power options but a noise level always stays the same. What do I do wrong?
THANK YOU.

Hi,

You can check to see if the suction power has increased. A quieter sound doesn't necessarily mean the suction power has decreased.

We hope the above information is helpful.
