HydraMaster's Boxxer 427 in combination with
rotary extractor tool and has earned the gold Seal of Approval for
its extractor from the Carpet and Rug Institute (CRI), signifying that
it meets the highest standards for carpet cleaning effectiveness.
Additionally, the Boxxer earned the Silver in combination with the Rotary DriMaster.
To qualify for the Seal of Approval, extractors must
undergo a stringent testing process at an independent laboratory that
measures three key performance criteria: amount of soil removed, amount
of water left in the carpet sample and impact of the equipment on
carpet fibers and appearance. Extractors that exceed average soil
removal standards receive a bronze rating. Those achieving higher
standards receive a silver rating, and those achieving the highest
level of soil removal are awarded the gold level Seal of Approval.
The testing protocol for extractors uses sophisticated
x-ray fluorescence (XRF) technology to measure the precise amount of
soil removed from a carpet sample. XRF was developed by private
industry and enhanced by NASA for the Space Shuttle program.
HydraMaster's gold-rated extractor was effective at
recovering water from the carpet test sample and cleaning without
damage to carpet fibers. These criteria are included because water and
dirt left in a carpet negatively affect the appearance of the carpet,
damage the fibers and create the potential for mold growth. Experience
has also shown that some equipment can cause excessive wear on the
