actually saying that, I just got a pretty relevant set of results with just "carpet cleaning machine"

The technique does work though, I have a search for a truckmount, but kept getting bugged by CB radio crap, stuff for lorries. Here's the search term I use now:
"truck mount -tamiya -mirror -traxxas -monster -buggy -hub -touring -spreader -suspension -michelin -amateur -boat -gutter"
and i also have an almost identical search except it is "truckmount and not truck mount, cos some folks put a space in between
Every time it emails you with stuff you don't want, pick a word to filter out the useless ones, but not one that'll obviously filter out the things yuo're looking for
