About Pressure Washers for Gutters
Pair a 130+ bar washer with a gutter-cleaning attachment (Karcher Gutter & Pipe Cleaning Kit or a J-shaped wand) and a 4–7m telescopic lance. Most jobs need under 100 bar at the nozzle.
Top picks: Kärcher K5 with Gutter Kit, Nilfisk Core 140 with telescopic lance, and the Bosch AdvancedAquatak 160 with extension lance.
Don't forget to flush downpipes too — blockages there are the most common cause of overflow damage.
