Tennant Company rejects Kärcher's charges of false advertising

September 27, 2011

MINNEAPOLIS — Tennant Company has strongly defended its advertising against recent claims filed by Germany-based Kärcher to affirm the effectiveness of its patented ec-H2O water-based cleaning technology, according to a press release.

"We are vigorously defending our company, technology and advertising against these baseless claims by a competitor," said Chris Killingstad, Tennant Company''s president and chief executive officer (CEO).

"We find it interesting that Kärcher would attack our ec-H2O advertising now, after we have been in the marketplace for three years, satisfied thousands of customers and have 2011 projected sales of $130 million to $140 million," Killingstad added.

Tennant''s innovative technology has been tested by independent third parties and by Tennant''s customers, who include many of the world''s largest professional facility services providers, the release stated.

According to the release, despite assertions in Kärcher''s own report that there is no "fully appropriate standard" for testing automatic scrubbers, Kärcher bases its claims against Tennant''s advertisements on flawed tests from one laboratory in Germany.

Its allegation that ec-H2O "does not have a cleansing effect" is refuted by Tennant''s testing and three years of customer testing and experience as well as by findings in Kärcher''s own report to the effect that ec-H2O performed identically to chemically based detergent in three out of four soil samples, the release added.

Moreover, the Kärcher-sponsored tests were applied to unrealistic soil samples and failed to control for certain key variables, the release noted.
