Part of the "Mighty Machine" series, the pages are packed with full-page photographs of street sweepers—both parked and in action. The simple text explains the basics about these giant, powerful machines, including important information about their major parts and functions. Some photographs include overlapped text in the form of a yellow arrow, showing readers where that particular object is located and breaking down the parts: the brush, vacuum, hopper, and sprayers. The machine's basic tasks are then described by explaining how they clean gutters and by detailing the importance of seasonally cleaning the streets. The book introduces early readers to subject-specific words that are defined in the glossary. Also included are "Read More," a list of books related to the topic, and an explanation of how readers can find more information on the Internet. With short sentences and large bold type, the text is a natural choice for beginning and reluctant readers. It will surely engage those interested in learning about the world.
