I can't name it, Miele is probably good enough. That's y'all mean right? Miele.

Bag is in the "lower-end" "better", than bagless.

With bagless to get mostly the best experience (until you figure it out yourself) you will need the original bags from the manufacturer since they fit the best. Otherwise you can use other ones if you figured out it's been the same.

I choose for a bagless one, since my apartment isn't that big and my floor consist of wood. But the filter needs to be cleaned too, yes even the bagless ones need to be cleaned. But it depends how much stuff you are vacuuming and big your house is.

If I had two kids and a partner, I would take a industrial vacuum cleaner. (Since the price is not much higher than the consumer one.)
