It was over the next few decades that the vacuum cleaner started to become a vital part of everyday life, rather than just a luxury.The machines started to become smaller, cheaper, and more effective, which led to them becoming more appealing to the mass market.. Cyclonic Vacuums Were an Important Innovation.

Until the 1980s, most vacuum cleaners were bagged models.These vacuums often generated strong suction, but had issues with losing suction power as the bag filled up.. Realising this was an issue, James Dyson decided to develop a. bagless cyclonic system.Instead of passing through a bag, air is spun at high velocities to force dust and dirt to the edge of the canister.

It’s then filtered or collected without the need for a bag.. Bagless cyclonic vacuum cleaners don’t lose suction as they fill up, which is an advantage over bagged vacuums.However, they have smaller capacities and are messy to empty, which is why there’s a place for both bagged and bagless vacuums today..

It’s important to point out that James Dyson wasn’t the first to come up with the idea of a bagless vacuum or a cyclonic vacuum.

His company was the one to popularise this design though.. Modern Vacuum Cleaners.Battery can’t be removed.
