Assembly was very easy. The only tool needed is a Philips head screwdriver. Have not used it yet but hope to be cleaning my patio and driveway very soon. If all goes as well as I expect I'll be buying the undercarriage washer accessory to help prevent rust and corrosion caused by the salt that is on our roads in winter here in New York. Large wheels will make this easy to maneuver on pavement or on grass.
