Alfred Karcher GmbH to sue Tennant

Alfred Karcher GmbH has announced that it has filed lawsuits against national companies of its competitor Tennant. The legal dispute in Germany, Belgium and the UK involves what Karcher says are misleading advertising claims by Tennant for scrubber-driers that use ec-H2O technology.

Karcher is taking legal action against several advertising claims made by Tennant, especially, it says, 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, with the result that a floor cleaning detergent no longer needs to be used.

Karcher says that these claims have been investigated scientifically by an independent research institute and refuted in an in-depth expert report.
Kathryn Lovik, Tennant's director of corporate communications has rejected the assertions, saying that the technology in question has been independently proven to be an effective chemical-free cleaning solution in most general purpose cleaning applications.

Its confidence in electrically converted water technology is substantiated by its own third-party, independent test results and analyses.
