Karcher is the No.1 best-selling pressure washer brand in the UK.
In 2017, the company launched the Karcher K5 pressure washer range – a revolutionary pressure washer with incredible cleaning capacity, designed and engineered with one very clear intention – to make outdoor cleaning simple, fast and effective.
The Karcher K5 has a powerful 145 bar water pressure, a 2100W innovative water-cooled induction motor and 500 l/h water flow, resulting in the K5 models having the capacity to remove even the most stubborn dirt and grime from almost any outdoor surface, which is remarkable considering they use at least 50% less water than a standard hose! The Karcher K5 doesn’t look half-bad either – the sleek, compact design is smart, modern, tidy and compact.
Pressure washing with a Karcher K5 is viewed by many as the most effective way to clean outdoors. Not only does a Karcher K5 deliver outstanding cleaning results, but it’s also incredibly easy to use: simply connect your device to the water supply and power outlet, turn on the tap, switch on your Karcher K5 and let the cleaning begin!

Full Control Plus Vs Compact
The Karcher K5 Full Control Plus range (RRP £349.99 – £449.99) aims to do exactly as the name suggests – put all the control into your hands with just the touch of a button.
The Full Control Plus models are equipped with a trigger gun and multi-jet spray lance; this means there’s no old-school swapping of lances – the 3-in-1 Multi Jet allows you to select a pressure setting and effortlessly move between modes, adjusting the water pressure to suit the surface you’re cleaning.
The Karcher K5 Compact pressure washer (RRP £279.99) has the level of cleaning power and high rate of energy efficiency we’ve come to expect from Karcher, but at the same time has been conveniently and meticulously designed to fit the brief of ‘small but mighty’.
The device features an innovative water-cooled induction motor, which extends the life of the pressure washer and enhances its performance. The Quick Connect system prevents the hose from kinking and reduces assembly time when connecting your K5 Compact to the water source. It doesn’t come with the 3-in-1 Multi Jet (reflected in the price) but does come with the Karcher standard Vario and dirt buster lances.
