DESC: The S183 has two tools on board, brushed edge cleaning, a powerful 10-amp motor and six-stage micron filtration.Unlike other vacuums, where the stream of dirt, paper clips and coins that are picked up pass through the fan of the motor (likely to cause major damage to the expensive component), Miele uprights are protected with a unique motor bypass system. This means that debris brought into the machine bypasses the motor housing. Such design protects the motor and increases longevity of the machine.
