Who is the Karcher K2 Plus for?

In short, the Karcher K2 Plus pressure washer is an entry-level elecgric pressure washer for easy to medium cleaning jobs. The model is perfect for small cleaning jobs, like driveways, patios, cars, and garden furniture. This is not a commercial pressure cleaner. If you’re looking to fight off years of dirt, then the more-powerful Karcher K5 would be a better option.

It is also ideal for people who do not have much storage space and don’t want a huge pressure washer that is hard to move around. The 16lb Karcher K2 has wheels and a telescopic handle that enhances the portability of the product.


  • Good performance for value
  • Lightweight
  • Good on-unit storage
  • Power adjustment
  • 2 year warranty


  • Will need to upgrade to the K4 or K5 machine for more difficult jobs


Power – The Karcher K2 features a 1.4 kW motor with 110 bar maximum pressure. This is enough pressure to clean hard-to-remove dirt from driveways and cards. It isn’t the most powerful in the range, but it can handle simple jobs no problem. It has a flow rate of 6 litres per minute, which allows you to remove dirt quickly and effectively.

Lance – As you can tell from the product name, this machine features a Full-Control vario lance that allows you to flick between four pressure settings. Each of these settings is easily changed via the turn of the knob. Although there are small icons which reveal the setting that is in use, the machine doesn’t have the LCD display found on the K4/K5/K7 models. The dirt blaster lance creates a powerful jet that rotates to provide up-to 50% more power than other entry-level models!

Portability – Many cleaning machine are heavy and hard to move from job to job. Fortunately, the K2 has a small build that weighs just 16 lbs (4 kgs) and can be transported with ease. In fact, the unit even has space to hold the extra parts and accessories, so you don’t have to do multiple trips from your storage spot. Even better, this upgraded model features two wheel so it can be rolled as you clean.

Auto shut-off – The K2 is energy-efficient too! It has an auto shut-off feature that automatically switches off the motor when it’s in use.

Detergent suction tube – Unlike other washers that require you to pour the liquids inside, the K2 has a suction tube that allows you to siphon detergent directly from the bottle.

Filter – The addition of a built-in inlet filter is an important feature that stops debris from getting into the machine. This isn’t an exciting feature, but it protects the longevity of your unit and maintains pump power.

Pressure Hose – Short hoses are a major pain. Luckily, the K2 comes with a nice 20 ft (6 m) long hose and a 35ft (10 m) cord that allows you to use the washer without having to frequently change power outlets. 

In the box – Karcher K2 Plus Pressure Washer, Vario Spray Lance, Dirt Blaster Spray Lance, T150 Patio Cleaner, and 500ml Detergent.
