You have not tried out your answer. Try it against the output of printf '[root@localhost ~]# ls \b\e[K\b\e[[K\b\e[Kpwd\b\e[K\b\e[K\b\e[K' to see how wrong it goes.

Ah, you also want to remove escape sequences in addition to non-printing characters. A second sed will accomplish that. I'll edit my answer...
