“Tennant’s so-called ec-H2O technology can achieve no better cleaning results in scrubber-driers than by using ordinary tap water,” Kärcher stated in a blog and in the suit it filed against its competitor before the Stuttgart District Court. After Tennant instituted legal proceedings against this statement, the Court’s 31st chamber for commercial matters today announced that the technology is to be investigated by a court-appointed expert.
“We welcome this ruling by the Stuttgart District Court unreservedly,” said Markus Asch, Deputy Chairman of the Kärcher Group’s Management Board. “The ec-H2O technology that Tennant advertises is now to be put to the scientific test by a court-appointed expert. That tallies with the approach that we have pursued since the start of the proceedings.”

Alfred Kärcher GmbH & Co. KG has filed lawsuits against national companies of its competitor Tennant. The legal dispute in Germany, Belgium and the UK involves false and misleading advertising made claims by Tennant for scrubber-driers that use the so-called ec-H2O technology.
Kärcher is taking legal action against several advertising claims made by Tennant, in particular the assertion that ordinary tap water can be converted into “active water” in scrubber-driers and that then has the same effect as a powerful cleaning agent. This process is said to create its own “powerful cleaning agent” with the result that an all-purpose cleaning agent no longer needs to be purchased. These claims were investigated scientifically by an independent research institute and have been refuted in an detailed expert report.
Scrubber-driers are cleaning machines for the wet cleaning of hard floors. They combine three functions: spreading the cleaning fluid, scrubbing the floor and vacuuming the dirty water.
