Kärcher K4 vs K7 - Where are the differences?
Where are the differences?
Let us compare the two high-pressure cleaners from Kärcher and look at the differences between the Kärcher K4 and the Kärcher K7.
Wasserdruck
The maximum pressure of the Kärcher K4 is lower with 130 bar. With the Kärcher K7 the maximum pressure is with 180 bar. Both pressure washers have a minimum pressure of 20 bar.Cleaning area
With a larger plot of land or a larger area to be cleaned, it naturally makes sense to pay attention to the cleaning area. With 30 m²/h the Kärcher K4 creates a smaller cleaning area. The Kärcher K7 cleans a cleaning area of 60 m²/h.
Performance
The Kärcher K4 provides a water flow of 420 l/h. With the K4 the water flow is 600 l/h. Thus the the Kärcher K4 is in front in comparison.
Hose length
The hose length determines how far you can move with the pressure washer. However, the length should not be a decisive criterion, as you can usually buy and connect another hose. With 6 m the supplied hose of the Kärcher K4 is shorter. With the Kärcher K7 a hose of 10 m is delivered.
Weight
The weight of a pressure washer can be decisive. The heavier the unit, the more complicated it is to move. However, a shearer machine is more stable. The Kärcher K4 is with 11.42 kg easier than the Kärcher K7. The K7 has a higher weight of 17.6 kg.
