unfortunately still unchanged bad. Sometimes I imagine that the sense of smell and taste is coming back. So far that was always just a brief "flare-up." Thanks for asking.
I'm not a fan of central vacuum cleaners. You always have to carry and store the hose, connection sockets... vacuuming stairs is also annoying. We have robot vacuums and also cordless vacuums. It's much more flexible and user-friendly. It can also be replaced more easily.
