Where are the differences?

Let us compare the two high-pressure cleaners from Kärcher and look at the differences between the Kärcher K3 and the Kärcher K7.

Wasserdruck

The maximum pressure of the Kärcher K3 is lower with 120 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 25 m²/h the Kärcher K3 creates a smaller cleaning area. The Kärcher K7 cleans a cleaning area of 60 m²/h.

Performance

The Kärcher K3 provides a water flow of 380 l/h. With the K3 the water flow is 600 l/h. Thus the the Kärcher K3 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 K3 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 K3 is with 4.7 kg easier than the Kärcher K7. The K7 has a higher weight of 17.6 kg.
