Who uses it
The K5 sits in Karcher's mid-to-upper domestic range, bought outright by homeowners for regular patio, car and garden furniture cleaning rather than hired. It is frequently the model UK reviewers and retailers use as the benchmark domestic Karcher pressure washer.
Closest alternative
The model most often cross-shopped against the K5 Power Control Flex is the Bosch AQT.
