I have a Ryobi cordless leaf blower. It's turned out to be one of the most useful tools I have.

Apart from blowing leaves, after using sanders or saws I give them a blast with the leaf blower and all the dust and filth is blown away leaving spotless tools.

After coffee this morning I washed the bits and pieces from the stove top coffee machine, and a variety of odd shaped things including the bottle brushes used to wash the coffee making stuff. A quick blast from the leaf blower and all the water was blown out of the nooks and crannies.

I have heating and air conditioning units on the roof of my house. The leaves from the neighbour's trees collect around the units and make a mess. A quick blast and the leaves are gone (possibly back over the fence ;-) )
