Sweeping changes in China
A Chinese city has introduced a new street-cleaning machine, composed of a tractor and more than a dozen bamboo brooms.
The street cleaner was spotted by tourists in Qinghuangdao city, Hebei province.
More than a dozen brooms are attached to a machine able to turn clockwise or counter-clockwise.
But the cleaner is only able to move litter and dust to the side of the street, where another has to clear it later.
