Water Cooled Motor
The best pressure washers benefit from a water-cooled induction motor which gives enhanced performance and a longer motor life.
Basically what happens is that as water is fed into the pressure washer it directs around the motor to act as a coolant before it is sprays out through the high pressure hose. this eliminates the need for a cooling fan and the power such a fan would absorb. Karcher pressure washers with a water-cooled motor have a longer warranty for this reason.
Aluminium Pump Head
Plastic and aluminium manifolds are used in domestic pressure washers with brass and stainless steel manifolds typically used for commercial machines.
Cheaper domestic pressure washers contain a plastic pump which can crack and wear much more easily than an aluminium pump head. Plastic pump heads can handle around 100-110 bars of pressure while aluminium can handle pressure between 150-200 bar.
Therefore an aluminium manifold is the prefered version for a domestic pressure washer.
Cleans 15m² per half hour
The Karcher K4 series cleans at least 50% faster than the Karcher K2 series however some reviewers have stated that this figure is actually understated and that the K4 series cleans at least 75% if not 100% faster than the K2 series. See the comment in the reviews below.
Assembly
Several reviewers mentioned that assembly and set up is not a problem with the K4 generally being set up in 10 minutes. bear in mind that Karchers instruction manuals only consist of diagrams so there is no written instruction on how to assemble the pressure washer.
This has led several people to assemble the pressure washer incorrectly initially so their set up time took longer than 10 minutes.
