Three things at once: suction pulls dust out of the fill, ultrasonic vibration shakes it loose first, and UV works on what suction cannot lift.
The HEPA filter is the part that matters if anyone in the house has allergies — without one, a vacuum on a mattress mostly redistributes the fine dust into the air you then sleep in.

Styling notes
Strip the bed and work in slow overlapping passes — UV needs dwell time and quick passes give it none. Do both sides of the mattress a couple of times a year and the pillows more often, since pillows collect faster than anything else. Rinse the HEPA filter on the schedule in the manual; a blocked filter costs you most of the 8 kPa.
