WHEN IT WAS INVENTED
ORIGINAL VACUUM CLEANER
John S. Thurman invented, in 1898, gasoline powered cleaner that was so big that had to be horse-drawn and didn't create a vacuum, but it blew the air and “cleaned” like that. The first vacuum cleaner that used the same principle as those that we use today was invented by Hubert Booth in England in 1901.

ROBOTIC VACUUM CLEANER
The first ever robotic vacuum cleaner appeared in 1996. It was made by Electrolux, Swedish household and professional appliances manufacturer and was called “Trilobite”.
