Vax UK Ltd is a brand that manufactures electrical goods and cleaning products in the floor-care and air treatment sectors, and which has its headquarters in the United Kingdom. The brand is owned by a company called TTI Co. Ltd Group, which is based in Hong Kong. Vax UK Ltd has its main headquarters and R&D centre located in the city centre of Birmingham, West Midlands and a service, warehouse and depot operation in the village of Hampton Lovett, near Droitwich, Worcestershire. Vax branded machines are manufactured in China. Vax employs over 400 staff across its Birmingham and Droitwich sites in the UK.

In June 1990 Vax contracted James Dyson to produce an upright vacuum cleaner aimed at the British market. This deal involved a £75,000 licence. By July 1991, he had left the company to produce this product independently.

In July 2010, Dyson attempted to bring legal action against Vax, over its Mach Zen vacuum cleaner, in the High Court for infringement of design patents. However, in 2011 the UK Court of Appeal rejected this claim.

In 2011, Student Placement Engineer Jake Tyler developed Vax ev, a working prototype of the world’s first cardboard vacuum cleaner. This product was featured across a number of techs and environmental online editorials including Gizmag and TreeHugger, and on the BBC Television series, Bang Goes the Theory. The cleaner is referenced as a key point in the history of Vacuum Cleaner development by the Best Cordless Vacuum Guide.

In 2014 Vax diversified its product range from vacuums, carpet washers and steam cleaners to include pressure washers, air purifiers and de-humidifiers.
