Some of the key points regarding Karcher k2 vs k3 vs k4 vs k5 vs k7 are as under:
- K2 Karcher
It is portable, strong, and light. It has a lance, a trigger gun, and a cable storage compartment. A detergent suction tube is provided for the application of detergents. It features a comfortable carrying handle. It has a 2-year guarantee and a water intake that prevents dirt particles from harming the pump.
- K4 Karcher
It has a water-cooled engine and a fast system for the high-pressure hose, as well as a plug-and-clean mechanism for changing its path between detergents. It includes a lance, trigger gun, and cable storage, as well as a three-year guarantee. This pressure washer is an excellent alternative for auto washing.
- K5 Karcher
It boasts a water-cooled motor with a unique cooling system that lowers wear and extends the machine’s life. It comes with an eco-rotator switch that reduces electricity and water use by 20%. It features a high-pressure hose with a fast system. For switching between detergents, use the plug-and-clean method. It also includes a suction line for pulling water from a tank or your outside water tap, as well as a filter kit and a 5-year guarantee.
- K7 Karcher
The top-of-the-line model has a water-cooled motor. It is the most powerful and also the most costly of the Karcher K series. The powerful motor produces high water flow and bar pressure, making it ideal for a variety of tasks ranging from cleaning your patio to removing graffiti from walls. The pressure can be adjusted to clean your car without scratching the paintwork, or set to maximum pressure for cleaning your driveway.
The K7 is worth the money if you want maximum power and will be using it for chores like cleaning slabs, patios, decks, or any brick walls.
Karcher rebased compact pressure washer models in 2019. For example, you may buy a Karcher K2 Full Control or K4 Full Control, as well as a Karcher K2 Compact or Karcher K4 Compact.
So, what are the distinctions? The compact version is smaller than the full control counterpart, yet it has the same specifications. The engine is the same, and you receive lance in terms of accessories, but the small version is more basic and lacks the visual options of the full control version.
The detergent bottle isn’t included; instead, you’ll receive a suction tube to plug into your bottle, which you’ll have to sit next to the pressure washer on the ground. The compact variants are also less expensive than the full control ones, so if you don’t believe you’ll use the detergent bottle function or require the full control lance, the compact version, which is also smaller and lighter, is a good option.
