I use both a hand held and a back pack blower depending on the pitch and amount of gutters needing to be cleaned. Hand held blower is a 4stroke Makita and the back pack is a shindaiwa
The BR550 is a reduced-noise model, I believe.
When all else fails, try the Gutter Clutter Buster gutter cleaning kit to VACUUM OUT all the wet and dry gutter debris. It really works great and you stay safe on the ground.
