Here's a tip which we used. Take your thinnest ( so it fits any gutter) nozzle tool, gaffa tape a dining fork at right angles (so it points along the gutter) don't bother to connect to vacuum, bend the fork prongs so they point along the gutter, walk along and flick them all out and vacuum off the ground, It will save you a lot of time. Obviously vac out remainder in gutter.
