Yes, the suction power adjustment can be done. This is due to the presence of a three-level suction adjustment system. The first level i.e., the normal suction is between 1000-1200 Pa, the second is between 1500 - 1600 Pa u0026amp; the third is between 2000 - 2200 Pa. The first level is apt for picking up minuscule particles like dust, the second can pick slightly bigger particles like pet hair, while the third suction adjustment will help the cleaner to pick up bigger particles like coffee beans.
