The first vacuum cleaner appeared in 1901 in Great Britain. Sesil Hubert But was the inventor. It was too heavy and loud and could only collect dust. But it saved London from terrible disease (plug),which was brought by soldiers.
This modern powerful machine
can clean the air or your carpet, wash it, kill the insects and mites. Any allergic element disappears.
It’s very little comfortable, and
quiet.
