I noticed that Screwfix were offering the Nilfisk C110.4-5 X-tra Pressure Washer for £69.99 so I decided to see what others were charging for this machine.
Cleanstore currently have it on offer for £64.99 with free delivery, but for £69.98 they will sell you the Nilfisk C110.4-5 X-tra along with a with Patio Cleaner and a Rotary Wash Brush, full details in this link.
