Let's start some fights

I want to install Linux on a Vacuum cleaner, which sucks the most?

Nix-OS. Nix translates to "nichts" in german, which translates to "nothing" in english. A vacuum creates sucktion force.

Also I get endless error messages sometimes, when I run nixos rebuild switch --upgrade, that sucks in a metaphorical sense, I need to modify the versions of programs I install.
