Thanks for adding the picture of the Scarab street sweeper. The Scarab may or may not be the first single engine sweeper. There needs to be supporting material whenever there is a superlative ("The X is the Y-est Z"), and the article needs to be in a neutral point of view, not a sales pitch. Note that The Elgin Pelican is powered by a single engine, although it is not truck mounted and is not a vacuum sweeper. A certain amount of power is required to run the carriage and mechanicals. This can be done by one or two engines and gearing and hydraulics. Group29 14:52, 14 August 2007 (UTC)
