I'm the other way. Got a vac and jet wash. Used the vac countless times and jet washed the gutters once.

I found the mess with a pressure washing lance was unbelievable - cack blasted everywhere - over the windows, over me and over next door. The only time I use it now is for the gutter clips now and again or for jetting a downpipe through with a drain jetter. Having unblocked a few downpipes lately I feel neither the vac or a gutter cleaning jet can cope with the s bend if it's blocked.
I had one downpipe that went off like i'd struck oil the other day

It was blocked right at the bottom because the moss and crud were rammed against the soakaway mesh. Twenty feet of black water on top of that just waiting to go off.
