Comparison Karcher WV 2 Plus vs Karcher WV 2 Premium

Working power of the machine for suction.

The effort with which the unit draws in pollution during operation directly depends on this indicator. The greater this effort, the higher the quality of cleaning and the more effective cleaning. On the other hand, even in the heaviest and most performant models, the suction power does not exceed 1200 W — it simply does not make sense to increase it further. In addition, we note that with an increase in the width of the grip, the suction power must also be increased, otherwise, the efficiency will decrease. It means that only models of the same type with the same or almost the same working width can be compared in terms of suction power.

The width of the additional nozzle provided with the device.

Additional attachments are mainly supplied with window models (see "Type"). Such a nozzle is usually made narrower than the main one — it makes it easier to work on small glasses and in hard-to-reach places. However, there is also the opposite option: a small capture width in the device itself, increased by using an additional nozzle.
