We highly recommend a pre-vacuum with a good vacuum cleaner before we arrive, but we understand if that’s not possible and offer a pre-vac service. Although, there may be an additional cost, depending on time, size, soil conditions, etc. Our truck mounted cleaning system has a powerful vacuum that is constantly running all the time, so we can take care of the pre-vacuuming as we clean on certain carpet conditions. *Notes on Vacuuming: Manufacturers recommend daily vacuuming for many carpet types. It is also recommend to vacuum over a spot in as many as six times in different directions to remove all the dry soil from it. *If you feel your vacuum is not working properly, or not picking up debris as once did, please let us know and we’ll be happy to take a look at it for you.
