I have a Neff pyrolytic oven, although it is now around 5 years old.
Yes, they are expensive but I wouldn't now have an oven that is not pyrolytic.
When we got ours I was a bit disappointed that it didn't clean the shelves and the side brackets, but have since learned on Mumsnet that these can be cleaned REALLY easily on bio washing powder and a Brillo pad.
You can pyrolise (don't even know if that is a word!) on three levels- I always use the 'strongest' one. It takes about 2 hours and then a while for the doors to unlock when the oven is cool enough, but after that it's only a wipedown with a damp cloth and as good as new.
I have noticed, however, that the glass door doesn't seem to be cleaned to the same standard- I guess because it's not made of the same material as the oven sides. Barkeeper's Friend sorts that out though.
I had an ordinary oven before and it was a disgrace! With my Neff I feel my MIL could look inside and not have a bad word to say about my housekeeping standards!
Love my Neff Pyrolytic oven!
