There exists in very many areas of the US a common property size for single family homes that is large enough to make "rake by hand" a significant time investment, but that is simultaneously small enough that a riding mower and sweeper is "too much" and/or "too awkward" to use. These tend to fall out into the 5,000 to 15,000 square feet (464.5 m^2 to 1,393.5 m^s for those using metric) range (with some slop on both ends of that size range). It is for this size yard where the 'leaf blower' found a "useful market" by turning an all day effort using a rake into an hour or so's effort using a blower. In my area, all the leaf blowers that do arrive are all carried by lawn work contractors. However, personally, I'm not bothered by them so their arrival during summer (grass clippings cleanup - always seemed a bit overkill but it is what the 'lawn work contractors' do) or fall (leaves) has never caused me an issue. Note: I'm not detracting from or dismissing the fact that others may be significantly bothered, just stating the fact that I'm personally not bothered by them.
