With the Siemens HB73GB550, you receive a multifunctional built-in oven with a number of useful functions. For example, the oven has a Hot Air Eco function to only heat up a part of the oven if you use 1 baking sheet. That way, you can save a lot of energy if you just want to prepare 1 pizza. In addition, it has a softClose door that prevents you from closing the oven door too hard. Cleaning the oven can be a tough job. That's not the case with the Siemens HB73GB550. The oven has a pyrolysis cleaning system, so it heats itself to 500°C to burns alls rests in the oven. You only have to wipe away the ash out of the oven. That's a lot better than scrubbing for half an hour with an abrasive sponge.
