The diameter of the suction tube (round pipe, not oval) was indicated on the package with 32mm, this information I endweder ignored in the description, or missing entirely. However, also 2 Adopterrohre with this, thus the nozzle should fit already on many models.
My vacuum cleaner AEG Electrolux Ultrasilencer, Produktionsnr: 910288821
Problem: the nozzle has now been drawn up after 3-4 years still on the ground, even with the brush of the carpet's no longer to fold up the suction. But now all water under the bridge.
Am very satisfied, the Interlockfunktion runs smoothly!
Strong buy recommendation!
