The Longevity Test
Miele vacuum cleaners are tested to last a minimum of 1,000 operating hours or an average of 20 years residential use. This is only because of the critical Miele-made component of the vacuum cleaner; its motor. The S4, and all Miele vacuum cleaners, feature a high-output, Miele-made Vortex Motor System. The motor is capable of consistently providing top performance for 1,000 hours.
The Cable-Pull Test
A malfunctioning cable reel assembly is frustrating. That is why Miele cables reels are put through a very aggressive quality assurance exam. The cable is pulled out and retracted over 10,000 times as a part of Miele's approval process. With this assurance, you can be sure you cord reel will function reliably and safely for years.
The Threshold Test
Quality assurance engineers at Miele's factory test the daily challenges of the vacuum's castors, bumper strip and outside casting using a volume of different tests. For example, on the threshold exam, the vacuum endures miles of track where typical and not so typical stresses are exerted - simulated door thresholds, bumps and harsh curves - in order to put maximum strain on the vacuum.
The Hose Test
Miele vacuum hoses are among the best in the world! Each production lot is subjected to countless bend and stretch tests in Miele's laboratories. To test the endurance of a hose, a vacuum cleaner, plus two additional 5kg weight, (that's over 11 pounds) is stretched thousands of times. The hose must pass undamaged before being approved for inclusion in a Miele vacuum cleaner box.
The Floor Test
Miele floor tools and accessory cleaning brushes are inspected just as thoroughly as the vacuums themselves. They are tested on miles and miles of different flooring, and must tolerate a fall test, in which the floor tools are drop from a height of nearly three feet over and over again. Only when the floor tools endure and pass the test, are they approved for production.
Silence-Noise Insulation
Thanks to a noise optimized fan and integrated silence -Noise insulation, the S4 is extremely quiet.
Powerful Vortex Motor System
A real power pack: the S4 motor is developed and produced in the Miele Factories in Germany.
-A 1,200-watt powerful performance.
-Optimal usage of power through airflow.
-The result: great cleaning performance with superior dust intake.
Thermal Cutout Indicator
A thermostat prevents Miele vacuum cleaners from overheating. When an object becomes lodged in the passage and blocks the flow of air, the vacuum will automatically switch itself off and the indicator light will alert you to the problem.
Forever Better! Immer Besser!
Miele canister vacuum cleaners are manufactured at Miele’s Bielefeld factory in Germany where endurance testing in custom-built laboratories forms an intrinsic part of quality assurance on all Miele canister vacuums. Quality, quality and quality, you only have three choices when it comes to Miele! Before any production process starts, components are put through very rigorous testing , in fact strain stress exceeds typical residential household use. Only when all components have successfully passed critical exam will the Miele brand name be placed on them.
