The Advance MX521 H became the latest extractor manufactured by Nilfisk-Advance to earn certification under the Seal of Approval category for extractor equipment. The machine is the 12th extractor in Nilfisk-Advance's line to earn certification.
Nilfisk-Advance is headquartered in Plymouth, MN and the MX521 H is listed as a portable machine earning certification at the gold level, assuring customers that it removes stains and soil from carpet without damaging the carpet pile or causing resoiling problems.
The CRI Seal of Approval program tests the effectiveness of carpet cleaning equipment and certifies deep cleaning extractors that effectively remove soil without damage to the carpet. Not all extractors are good enough to earn this distinction; the blue and green seal helps customers recognize they are buying quality products.
An independent laboratory administers the CRI Seal of Approval testing for extractors. To quality for the Seal, extractors must meet stringent standards in all three-test categories:
• Amount of soil removed from the carpet
• Amount of residual moisture removed from the carpet from a wet cleaning process
• Impact of the equipment on carpet fibers and appearance
In addition, soil removal efficiency is rated on three levels. Extractors that exceed average soil removal receive a Bronze Seal rating. Those achieving higher soil removal receive a Silver rating and those receiving the highest level of measurable soil removal are awarded a Gold level Seal of Approval. A total of 77 extractors have earned SOA certification.
