Cleaning with Electrolyzed Water


Water. It makes up 50-65 percent of the human body. It covers approximately 70 percent of the earth. It has shaped our land, served as a barrier and a travel route throughout history, and is one of the most important factors to sustaining life as we know it.

This year, we celebrate the 10th anniversary of Tennant Company introducing a different way to use water - ec-H2O Technology. Scrubbers equipped with ec-H2O technology electrically convert water into a detergent-free cleaning solution that cleans effectively, saves money, improves safety, and reduces environmental impact* compared to traditional cleaning chemicals and methods. The technology initially launched on select Tennant and Nobles Walk-Behind Scrubbers in 2008 and expanded to select Rider Scrubbers by 2009.

The second generation of ec-H2O Technology, ec-H2O NanoClean®, was introduced on the Tennant T300 / T300e and Nobles Speed Scrub 300 Walk-Behind Scrubbers in 2016. ec-H2O NanoClean Technology offers the same great benefits of the first generation, but now cleans better by cleaning more soils in more applications.** Shortly after the launch of ec-H2O NanoClean, the technology replaced the first generation of ec-H2O on other Tennant and Nobles commercial scrubbers.

Since their launches, ec-H2O and ec-H2O NanoClean Technologies have been included on more than 104,500 machines worldwide. The adoption of thesee technologies is helping us in our mission to create a cleaner, safer, healthier world.

* Based on a study by EcoForm™. 

** ec-H2O NanoClean cleans more soils in more applications than the original ec-H2O. ec-H2O NanoClean technology is not suitable for all soils, including heavy concentrations of fats and oils.  Depending on the type of soil, conventional chemical cleaners may be required.
