Carpet cleaner for a weekend (Corstophine EH12)

Hi kind sharers, I am looking for a carpet cleaner that could remove some sketch/paint marks from the rugs. I don't want to invest in a new one as our rugs are not too bad. I would really appreciate it if someone would be willing to let me borrow yours for a weekend please. I'll take real good care of it and return it as is :-) Appreciate your time and help :-)
