PLYMOUTH, MN — Nilfisk-Advance, one of the world's leading manufacturers of professional floor cleaning equipment, today announced the results of independent testing of the performance of electrically-activated water technology on professional floor scrubbers. The results show that a floor scrubber using electrically-activated water technology did not perform better than when that same floor scrubber used ordinary tap water, contrary to claims in the marketplace that electrically-activated water "converts" tap water into a "powerful cleaning agent/detergent" when used on floor scrubbers.

"The claim that electrically-activated water acts as a 'powerful cleaning agent/ detergent' on professional floor scrubbers was not supported in our testing," said Wade Reitmeier, General Manager, R&D & Product Management for Nilfisk-Advance. "Such claims must be met with careful analysis because our industry relies on credible science to provide products and services. To evaluate the performance of electrically-activated water on floor scrubbers, Nilfisk-Advance worked with several experts to design a comprehensive test procedure using accepted ASTM standards and best industry practices," said Reitmeier.

Nilfisk-Advance retained two independent and internationally accredited labs to test the cleaning performance of today’s current floor scrubbers equipped with electrically-activated water technology. The labs measured the cleaning efficiency when using three different cleaning solutions: 1) with electrically-activated water; 2) with plain tap water; and 3) with tap water and detergent.

The results show that the floor scrubber using electrically-activated water performed no better than when that scrubber cleaned with only tap water. The results also indicate that when cleaning with electrically-activated water, the scrubber did not clean as effectively as when the scrubber cleaned with tap water and detergent.

"These independent lab test results make clear that if customers are paying a premium for this technology, expectations as to value and performance are unlikely to be met," said Steve Baker, Vice President of Sales & Marketing for Nilfisk-Advance. "In this case, the testing simply does not support the claim that electrically-activated water on floor scrubbers is a 'powerful cleaning agent/detergent,'" said Baker.

Electrically-activated or not, water is, and always has been, an effective cleanser on a variety of floor conditions. Floor scrubbers are routinely used with plain tap water and can effectively clean a range of soiled floors. Some floor conditions, however, do require the use of detergents when deeper cleaning is necessary.

"These test results validate what we have known all along—you don't need special water to clean floors. Plain tap water—by itself on an effective scrubber—can clean many surfaces very well," said Baker. "But our customers have a wide range of floor-cleaning challenges, and rarely is there a one-clean-fits-all solution. With this understanding, we introduced the EcoFlex™ System on our Advance brand floor scrubbers in 2009, which is the industry's first technology to provide total flexibility to effortlessly switch between chemical-free/water-only cleaning or different cleaning intensities at the touch of a button as floor conditions dictate. Nilfisk-Advance's strong sales of EcoFlex™ reflect the marketplace's understanding of the cleaning power of ordinary tap water and the reality that certain soiled surfaces at times require detergent," added Baker.
