Kärcher Brings Floor-Cleaning Patent Claim against Tineco

Kärcher brought a patent claim against Tineco at the Unified Patent Court's Düsseldorf division in mid-August 2026, JUVE Patent reported on September 29. The dispute concerns EP 3 079 553 and carries reference UPC-CFI-0003016/2026. The report did not name the accused products.

The published patent describes a manually guided floor-cleaning machine with a rotating, textile-covered roller and a suction system. Its first claim sets out the relationship between the roller and the opening of a suction channel, including walls positioned to interact with the cleaning material.

That technical detail places the subject in the mechanics of floor washing and dirt recovery. It is more specific than a general claim to a machine that both vacuums and mops. The patent also describes arrangements for supplying cleaning liquid and collecting dirty liquid, explaining how several functions can be combined around a roller.

The news is the filing of a claim, with infringement still to be determined. For readers tracking floorcare technology, the underlying document provides useful context on the cleaning mechanism at issue, while the products and conduct covered by the actual dispute remain questions for the case record.
