AEG 90027761800 – Plus.Parts® Filter Renewal Kit

The AEG 90027761800 is a retail catalog number for the AEG QX9-1, a 21.6V cordless stick vacuum with BrushRollClean LED motorised nozzle distributed through specific retail channels under numeric article numbers. The post-motor filter on the QX9-1 handles exhaust air after it passes through the motor chamber, it captures the fine particles the motor sheds during operation and any fines that escaped the pre-motor stage, ensuring the air exiting the exhaust vent meets AEG’s filtration standard. A post-motor filter that is overdue for renewal often signals itself through a faintly musty or dusty exhaust smell that returns shortly after the housing is cleaned. Washing the filter removes surface loading but cannot restore a filter medium that has degraded below its effective filtration threshold, which is why AEG recommends replacing both filters at the same interval even when only one appears visually due.

This filter renewal kit contains Plus.Parts® components for the QX9-1: 3 washable pre-motor filters, 3 washable post-motor filters, and 1 cleaning tool. Dimensions verified for the QX9-1’s dual filter housing. Seven pieces, both filter stages renewed in one order.

At a glance

• Both Stages Renewed – Replacing pre-motor and post-motor filters together ensures neither a fresh pre-motor filter pushes through a degraded post-motor medium.

• Housing-Matched – Filter dimensions verified against the QX9-1’s dual filter housing, confirmed for the 90027761800 retail variant.
