Vacuum cleaner
The vacuum cleaner evolved from the carpet sweeper via manual vacuum cleaners. The first manual models, using bellows, were developed in the 1860s, and the first motorized designs appeared at the turn of the 20th century, with the first decade being the boom decade.
Henry (vacuum)
Numatic vacuums with faces on the body/canister (Numatic Henrys did not actually say "Henry" on the cap until 1981) were invented first in 1979, 123 years after the first invention of the vacuum. In 1981, the first Numatic model to say a name on the cap (Henry) was created. The first model of Henry started as somewhat of a toy, with the functionality of a vacuum. The face appealed to children and adults alike, and was very popular for its lovable face. Henry was also one of the first vacuums to use Microfiber dust bags, which are large capacity dust bag known as HEPA-FLO bags which are made of a strong material that carry dust and other unwanted materials into the HEPA-FLO and stay in there unlike any paper bags which tend to rip and leak dust. Since the introduction of Henry in 1981, it has sold 7-8 million units, with around 20,000 more being sold each week (roughly 2857 per day). In 2017, the EU introduced a new law that gave vacuum cleaners a limit to their wattage, making 900W the maximum.. This required Numatic to change about 80% of their vacuums, because most of them were 1200W. The new law was meant to conserve power, and also bringing the average cost of vacuum cleaning per year from £11 to £7.
