The AEG 90027769300 is a retail catalog number for the AEG QX9-1, a 21.6V cordless vacuum sold under numeric article numbers through specific channels while carrying the same specification as every other QX9-1. The relationship between the filter stack and the battery on this platform is direct: the 21.6V lithium-ion pack delivers its rated runtime at unrestricted airflow. A pre-motor filter loaded with fines increases the motor’s resistance to airflow, which forces the motor to draw more current from the battery to maintain the same suction output. That additional current draw shortens the effective cleaning time per charge without any actual loss in battery capacity. Addressing filter maintenance is therefore the correct first diagnostic step when runtime appears shorter than expected, ahead of assuming the battery has degraded.
This filter supply set contains Plus.Parts® components for the QX9-1: 3 washable pre-motor filters, 3 washable post-motor filters, and 1 cleaning tool. Both filter types verified against the QX9-1’s dual filter housing dimensions. Seven components, both stages covered.
