If you choose a cordless battery-operated blower, you'll just need to wipe the exterior down and look out for any buildup of dust and debris around the air intakes. You'll need to clean out any small leaf particles from both the blower and the bag if you're using them together. A gas-powered blower needs a general tune-up every year. You'll also need to make sure there's a supply of gas on-hand. If you're using an electric leaf blower, you won't need to mix any oil or buy a pre­blended mix. The larger walk-by blowers require more maintenance because they have many more moving components.
