The AEG 90027751100 is a retail catalog number assigned to the AEG QX9-1 for specific distribution channels, the machine inside is identical to every other QX9-1, built around a 21.6V motor assembly with BrushRollClean technology and a dual washable filter stack. The dual filter path is what distinguishes this platform from single-filter designs: the pre-motor filter captures the bulk of household dust before the motor, and the post-motor filter scrubs the remaining fines from the exhaust. Owners who rely on a quarterly service interval often find suction degrading before that date because both filters accumulate fines simultaneously. AEG recommends a monthly inspection and wash for both, with replacement every three months under typical household use.
This consumables kit contains Plus.Parts® components selected for the AEG QX9-1 filter system: 3 washable pre-motor filters, 3 washable post-motor filters, and 1 cleaning tool. Both filter types are dimensioned for the QX9-1’s dual-slot housing. The cleaning tool corresponds to the BrushRollClean nozzle specification. Seven pieces, the complete filter service for one replacement cycle.
