Karcher K4 Premium Ecologic review

Price: £248.17 Hose: 5.5m

There's no doubting this washer’s eco-friendly credentials with its green hose and lead. The ‘green’ bit is its ecologic mode, which reduces the pump’s power and claims to reduce water and energy consumption by 20 per cent. This efficient mode is enough for most car cleaning jobs. It also has a hose to run from a water butt. It all works pretty well, but it’s not cheap.

Zip-merging is fairer, faster and recommended by all the experts. So why do UK drivers refuse to do it?

Steve Walker is completely flummoxed as to why UK drivers can’t get their heads around this simple principle.
