Last, but by no means least, for a little extra, you could opt for the Kärcher K4 Full Control ( £165), which offers 1,800W of power, a maximum pressure of 130 bar and a choice of nozzles. Alternatively, there’s the Spear & Jackson S2011PW ( £150), a powerful 2,000W unit that boasts a maximum pressure of 160 bar and onboard storage for stashing away its wide variety of attachments. While all of the models can be used with detergent (the 1,300W model requires an external detergent pump), none come with any in the box.įor a similar price to the 1,800W model, you can buy the Nilfisk Compact 120 High-Pressure Washer ( £110), a 1,400W machine that offers a maximum pressure of 120 bar, as well as two cleaning nozzles and a foaming lance. The top-end 2,100W variant comes in at £188, while the 1,300W model costs just £58 – although this one doesn’t come with any brushes or a patio cleaner. The 1,800W machine sits in the middle of the Mac Allister pressure-washer range, with a price tag of £128.
