I read your entries and I decided to buy a Miele condenser dryer with a heat pump, it was on a discount from PLN 3800 to PLN 2939. I also considered a Siemens iq700 with a steam function, the price is similar to PLN 2700. However, I chose Miele because of the double filter in front of the capacitor and easy access to it. After 5 drying cycles, dust was already visible on the sponge. The sponge drips easily and can be vacuumed. The Siemens solution is a misunderstanding, a self-cleaning exchanger to which there is no access, will get stuck with dirt after a while and the machine will stop working. In some Bosch cars, I have seen a solution where only the exchanger is washed in a situation where the condensed water accumulates in the tank. The function stops when connected to a sewage system. Here you can see how the manufacturer disregards users.
