The Clean Machine

Is there anyone else out there wondering about the street cleaner and what it actually does?

Does it really sweep the floor of the ground to make our streets cleaner? I mean all i see is the brushes around the truck go round and round in circles and the brush on the bottom roll the floor, but does the actual dirt get swept into the machine? or is it just swept and causes more dust and dirt in the air and the area around where it just swept?

Anyhow...just wondering if there was some kind of laboratory that actually tested how much dirt and dust is collected and if the area around it is more dirtier after than before!
