when was the first dyson vacuum cleaner invented
Dyson (company) Dyson developed 5,127 prototype designs between 1979 and 1984. The first prototype vacuum cleaner, a red and blue machine, brought Dyson little success, as he struggled to find a licensee for his machine in the UK and America. Manufacturing companies like Hoover did not want to license the design, probably because the vacuum bag market was worth $500m so Dyson was a threat to their profits.[5]
Thomas Crapper The flushing toilet was invented by John Harington in 1596. Joseph Bramah of Yorkshire patented the first practical water closet in England in 1778. George Jennings in 1852 also took out a patent for the flush-out toilet.[4][5] In a time when bathroom fixtures were barely spoken of, Crapper heavily promoted sanitary plumbing and pioneered the concept of the bathroom fittings showroom.[citation needed]
