Just a note about our pressure washer range
We supply (and often build) pressure washers that start from £800.00 up to £15,000

All the cold water ones have the commercial Honda GX range of engines or Diesel powered rather than the lower spec Honda GC range. We dont want problems for us or our customers which is why we carefully selected the range we sell. We use Izusu diesel engines for our very big big van and trailer mount units.
The pressure washer we selected for the full gutervac package is absolutly top of the range for a fully mobile cold petrol powered unit, incorporating a reduction gearbox and oversize pump to prevent excesive engine wear.
When used for gutter cleaning it runs with minimum effort and could run all day with out putting any strain on the engine. This pressure washer can and easily run any size Whirlaway for paving cleaning a service which many of our customers also offer as an add on. We also hire out these units so they have to be reliable and hard wearing. .... So thats the reasoning behind the choice.
I know there are plenty of much much cheaper petrol and electric power washers available from other sources, we set the standard of what specification of equipment we want to supply so we choose not to supply bottom, middle or even the lower level upper range.
We often we supply connectors to link up our high pressure PowerPole to a customers own pressure washer but only if the lance and hose can be detached from one another and they have a screw thread or standard HP push fit connectors (which the very cheap one often dont).
