We find that if this carpet is at all matted down, you will not remove all the loose soil vacuuming. I would recommend raking the carpet, especially the high traffic areas, before vacuuming. Also, take your time vacuuming and make sure you are getting air flow under the vacuum for suction (i.e. don’t put the bar on the lowest level). If you use the dirt napper, which works well on this carpet, you may want to keep the vacuum handy as you may dig up some stuff that will require another pass with the vacuum.
