PUT TO THE TEST

Miele tests all its vacuum cleaners vigorously to ensure they surpass average usage standards – cases and castors are put through their paces with machines given no less than 16,500 bumps to ensure durability, and the cables are wound out and retracted more than 10,000 times to test their resilience. All models are trialled on more than 2000 kilometres of carpet, and tested to operate for 780 hours.
