In commercial carpet care we want to help you get the full life out of your carpet investment.  Vacuuming regularly in high traffic areas can greatly decrease the "soil load" of your carpet.  However carpet manufacturers often recommend low moisture soil encapsulation cleaning in between steam cleanings.  This is common in Hotel Lobby's and Medical Offices for example.  The carpet looks better each time you vacuum after using this method.  

Low Moisture Carpet cleaning is rarely effective on carpets that have oil and grease residue; like restaurants for example.   But, this is a very cost effective way to get the most out of your commercial carpet.
