Dyson and Hoover in Vortex row

Dyson Appliances is taking legal action against rival Hoover at the High Court, over allegations that Hoover is using Dyson-patented technology in its Triple Vortex vacuum system.

Dyson claims that by including two or more centrifuges in its Vortex cleaner, Hoover contravenes Dyson’s patents. A Dyson spokeswoman says the company has also written to Hoover to complain about the accuracy of its advertising, which claims the Vortex cleans the air as efficiently as other products. She says Dyson’s tests show the air emitted from the Dyson DC04, which uses dual vortex technology, is over 200 times cleaner. “At the moment we are waiting to hear back from the High Court,” she adds.
