Miele S5 Callisto S5281 Vacuum

Miele S5 Series Vacuum Cleaner Endurance Testing

Longevity Test:  Miele vacuum cleaners are tested with a required result of 1000 operating hours.  1000 operating hours represents about 20 years of residential use.  It is the critical primary component of the Miele vacuum cleaner that accounts for this longevity, and that component is the Miele Vortex Motor System. 

Floor Test:  Miele's floor and accessory tools are tested on miles and miles of different flooring.  The tools and brushes are carefully and methodically inspected, just like the vacuum cleaners. Finally all tools must pass a drop test where they are repeatedly dropped from a height of almost three feet.  When they pass this test then, and only then, are they ready to proceed with production.

Threshold Test:  Miele vacuum cleaners are put through a series of tests that simulate the daily uses and abuses a vacuum cleaner goes through to make sure the bumpers, casters and outside casing all meet Miele's high standard of excellence. The threshold test is just such a test. Here Miele vacuums travel miles of track with simulated door thresholds, bumps, and curves to put the most stress possible on the machine. 

Hose Test:  Because of the rigorous testing they go through, Miele hoses are among the best in the world.  Every single production lot goes through countless bend and stretch tests.  To test the endurance of the hose, the hose,  a Miele vacuum plus an additional 5kg(11 lbs) is stretched thousands of times. Passing this test undamaged is necessary to be included in the Miele lineup of products. 

Cable Pull Test: A broken cordwinder is absolutely one of the most frustrating things.  Miele cable reels (cordwinders) endure an aggressive quality assurance test.  The cord is pulled out and retracted over 1000 times before it is approved.  This gives you the assurance that the cordwinder on your Miele vacuum cleaner will work for years and years.
