What’s the difference between the Karcher K2 and Karcher K2 Compact?

The power rating and water pressure are the same for all models in the K2 range –  the water pressure output stands at an impressive 110 bar, with a 1400W air-cooler power-rating.

Where the K2 and the K2 Compact differ is in the size and design. The K2 Compact is what it says on the tin – compact –  and it’s clearly been designed with one simple goal – to be as small as possible whilst still delivering the outstanding cleaning results we’ve come to expect from Karcher.

The K2 Compact is considerably smaller than its big brother the K2. The K2 standard is 6.2cm longer, 6.1cm wider and an incredible 39.4cm taller than the K2 Compact! The K2 Compact is also considerably lighter than the standard K2 – 1.1kg lighter to be precise – meaning it’s easy to carry; particularly handy if you live in an apartment block, store your K2 upstairs, or suffer from back problems meaning you find lifting and carrying difficult.

You’ll be looking at paying about £15 more for the convenience of the compact model but it’s definitely worth considering if you live on an upper floor, have limitations when it comes to physical activity; or have restricted options when it comes to storage.

Karcher K2 Full Control models

Four years ago, Karcher updated its range of pressure washers to include the Full Control variation. Any models which fall under the Full Control nametag are fitted with the Karcher LED display trigger gun – a genius concept in pressure washers that assists you in selecting the ideal water pressure output suitable for the surface you’re cleaning.

For example, a concrete outbuilding covered in moss, bird mess and garden grime will need a greater amount of pressure exerted onto it than the paintwork of a car or conservatory glass – low impact surfaces such as these are more vulnerable to damage and/or erosion than high impact surfaces and so require less intense pressure. Both the K2 Full Control and K2 Full Control Home are fitted with the trigger gun feature.

The K2 models will allow you to select just the right amount of power and control for the most effective outdoor clean, without damaging low impact items such as delicate garden features, cars, guttering or grouting, which such as driveways, garage doors, or brickwork.

Why choose a Karcher K2?
