Is there a noticeable scuffing sound when running on smooth tile floors?

(1) The robot adopts floating roller brush design can better clean the floor trash;
(2) The brand new rubber strip of the roller brush cover rubbing against the smooth tile floor is easy to produce a strange sound, which does not affect the function of the robot and will not damage the floor;
(3) Use the robot a few more times and the noise will disappear.
