Does the Clean Booster make noise when moving up/down and left/right?
When the Clean Booster moves up and down or swings left and right, noise can be generated at the ends to get the correct position.
This sound is made while identifying the exact location and initializing it, so it is safe to use.
Is it making a noise after cleaning the Clean Booster or the care manager’s visit?
If the fan is not assembled correctly after cleaning the Clean Booster, noise may occur during the product’s operation.
If it started to make noise after the care manager’s visit, please check with the care manager first.
※ If the noise continues, please have a professional service manager check the product.
