The filter is actually two parts – a foam ring and an outer shell – and you should separate these to wash separately.
Dyson Takes a Cyclonic Approach.In the late 1980s, nearly all vacuums still had a bagged design.
These worked fine, but suffered from the suction loss mentioned in the previous section.The more dirt the bag contained, the worse suction became.. James Dyson decided to try a different approach to solve this issue.Instead of using a bag to “catch” the dirt and dust, he created a bagless cyclone system that spun the dirty air in a circle at high speeds..
When air is spun at high speeds, dust is pushed to the edge of the container where it can be filtered or collected.This replaces the need for a bag to filter the air.. More importantly, it also means that air doesn’t need to pass through all the collected dirt.
The result is that suction power doesn’t decrease as the bin fills up (as long as you empty the canister before it’s full.).
James Dyson spent many years perfecting this design, before eventually releasing the DC01 as the first.He had seen a machine that attempted to clean by.
air to stir up dust into a bag, which he realised was the wrong way to approach the problem.. At the time, the idea of sucking air through a filter to pick up dirt was considered to be impossible.But Booth soon succeeded in making the machine – even though it had little resemblance to the lightweight machines we know today.. Manual Vacuums.
Before electric vacuum cleaners, manual vacuums (or carpet sweepers) were available.These were first invented in 1860 in America, and relied on a brush and fan to stir up and collect dust..
