Agriculture | n. m.
machine that is used to harvest the fallen olives from the ground by means of sucking.

Example

After raking the earth, leaves and olives together, the collection is heaped into a trailer. [The harvester] walks around with a ghostbusters-type machine, a reverse hoover that usually blows the olives into a pile.

Additional information

even if its used is becoming spread, just as the sweeper, the hoover has the disadvantage that it collects soil and therefore a cleaner should be used after wards. It can also damage the skin of ripe fruits.
