Some of the most striking features of the Siemens iQ500 Heat-Pump-Dryer are its stainless-steel look, an illuminated ring around the rotary selector, and the offset porthole. Thanks to its self-cleaning system, maintenance of the unit is kept to a minimum. Lint is collected in a large container that needs to be emptied less frequently. The operation of the dryer is intuitive; additional functions can be conveniently selected via the illuminated LED control panel.
