S4·E4 Street Cleaner
Aired September 30, 2001
Synopsis
The teams have to build a four-man machine to clean up litter. Different kinds of rubbish (such as old cans, plastic bottles, newspapers, cardboard, old clothes and bin liners) will be spread over an area 50x50m and the teams will have half an hour to pick up as much as they can. When time is called, the winning team will be the one with the heaviest load of litter.
