Only one fetafilter. Really? Before that, there were two different ones and each had a synthetic mesh, followed by a sponge and only then a fetafilter. And there is only one fetafilter. I don't think it will be long enough. Navigation compared to the previous one is just great. He always got stuck somewhere or started vacuuming a single corner with something he liked. Well, the sills for this model are much less dangerous.
