[LG CordZero R9] The noise gets loud and quiet repeatedly

Troubleshooting

While using the robot vacuum cleaner, does the motor noise get loud and quiet repeatedly?

LG Electronics’ robot vacuum cleaner with AI and deep learning technologies can assess and clean various spaces such as kitchens, living rooms, rooms and etc on its own.
Especially, when you enable the smart turbo function, depending on the amount of dust, the floor material and the shape of the room, the robot vacuum cleaner will adjust its suction power on its own.
As a result, the noise level might differ.

Try this

While the robot vacuum cleaner is in Intense cleaning mode, are noises getting loud and quiet repeatedly?

➔ It is natural as high suction power is used for cleaning.

If you select the intense cleaning mode, then the robot vacuum cleaner will set a space with the size of 1.5m x 1.5 m and then clean the area while drawing a square pattern.
Compared to when in perfect or zigzag cleaning modes, it uses higher suction power, so the noises can get loud and quiet repeatedly.
Use it when you want to focus on highly polluted areas.

While the robot vacuum cleaner uses the smart turbo function to clean areas, are noises getting loud and quiet repeatedly?

➔ It is natural effect to be observed as the robot vacuum cleaner first assesses the cleaning space and then increases the suction power on its own.

If you select the smart turbo function, the robot vacuum cleaner will use the dust sensor to assess places with lots of dusts and increase the suction power accordingly.
Also, when it moves over a rough floor or over a carpet, it increases the suction power to completely clean everywhere.
If you select the smart turbo function as well while already using the perfect cleaning mode, it will increase the suction power to clean all edges of walls and rooms.
