Who invented the first portable vacuum cleaner in 1905?
The first vacuum-cleaning device to be portable and marketed at the domestic market was built in 1905 by Walter Griffiths, a manufacturer in Birmingham, England.

First cleaning machine that used a vacuum and that could be carried around was designed by Walter Griffiths in 1905.
It used bellows to suck up dust and a flexible pipe.
James B.
Kirby invented vacuum the machine in 1906, called the "Domestic Cyclone”, which used water for dirt separation instead of a filter.Does vacuum cleaner remove dust?
Vacuum cleaners are not only effective at cleaning dust and getting rid of allergens, they are also easy to use, they save time and energy.
They are equipped with suction motors and filters to pull in dirt and dust.
They can be categorized into hand-held, canister, vertical and robot vacuum cleaners.- Vacuum cleaners use an electric motor that spins a fan, sucking in air – and any small particles caught up in it – and pushing it out the other side, into a bag or a canister, to create the negative pressure.
