Ionised water does not have a cleansing effect

Cleaning equipment manufacturer Tennant is sued for making misleading

Alfred Kärcher GmbH & Co. KG, parent company of Windsor and the world market leader in cleaning technology, has filed lawsuits against national companies of its competitor Tennant. The legal dispute in Germany, Belgium and the UK involves false and misleading advertising 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, especially the assertion that ordinary tap water can in scrubber-driers be converted into “active water” 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 a floor cleaning detergent no longer needs to be bought. These claims were investigated scientifically by an independent research institute and refuted in an indepth expert report.

“In recent years we have achieved significant global sales growth with our scrubber-driers, and also in 2011 we’ll continue to increase” says Hartmut Jenner, Chief Executive Officer and Chairman of the Management Board of the Kärcher Group. “As a leading cleaning equipment industry company we also stand for the respectability and trustworthiness of our industry. Our customers must be able to rely on their manufacturers. Tennant’s claims are misleading and totally untenable scientifically. The company is thereby trying in a highly unfair manner to set itself apart from the competition – and making a promise to customers that it cannot possibly fulfil.”

Kärcher currently employs over 8,000 people in 50 countries and 75 subsidiaries. Founded in 1935, the family firm manufactures its cleaning equipment in Germany, Italy, Romania, the United States, Brazil, Mexico and China. Fifty thousand service points in countries everywhere ensure that customer service is available all over the world. Over 600 engineers and technicians work at development centres devising new problem solutions. In 2010 the cleaning specialist Kärcher reported its highest-ever sales revenue of more than EUR 1.5 billion and sold over 7.3 million items of equipment – the largest-ever number in the company’s 75-year history.
