Mobi’s latest power washer builds on the success of the V-15, which was launched last year. The V-17 has a larger, 17-litre tank and runs from the mains, 12V or its built-in rechargeable battery. Charge it up from the mains before you set off to clean your van on site without draining your leisure battery.

One charge is good for an hour of power washing. The tank is removable and the nozzle provides reliable control of the powerful jet stream. Performance is excellent, even on battery power, making light work of muddy boots. The V-17 is well designed and solidly built.
