We have a Miele (something very similar to the S2111 linked above).
It is okay. It is better than our ancient dyson was, but that was pretty worn out.
It doesn’t have a beater brush, if you like those.
It sucks very very powerfully, which is good, but it does feel very brute force – to pick up dirt reliably, you have to whack it on maximum suck, in which case it threatens to pull up carpets. Not sure what it is, it kind of feels like the floor head bit isn’t very well designed. It is nice and quiet, much quieter than the dyson ever was.
The small miele ones like that go through dustbags like they are going out of fashion too (maybe 1 every 4 times we clean the house) and even ebay imitation ones are something like 50p a bag. That’s part of why they recommend them as a ‘second cleaner’. Is okay if you’re scuzzers like us and clean once a week, but if you get a lot of use out of your hoover, expect to have to buy loads of bags.
