In moving clutter our vacuum cleaner was stored. So had to be purchased quickly replacement. After good experiences with AEG Mignion the choice fell on the AET 3510. After nearly four weeks without vacuum cleaner had the New insist today equal to a hardness test. And he has mastered all the tasks with flying colors. The suction power is amazingly strong and consistent. The collection container can empty very easily. Besides the AET 3510 remains pleasantly quieter than the Mignon in operation. Overall, the vacuum cleaner in this price range is certainly a worthwhile purchase. Irritated have the manual without German version and a patched carton. But here is to evaluate the device; and has earned five stars.
