how mobile do you want a dirt worker to be? As long as i can carry it from a tap to my car, thats as mobile as you’d ever need surely?
So that has a handy strap, why would you bother? Plus you have to keep pumping it to get any pressure. I used a similar one for a while, thought it was shite, so bought a dirtworker. They are what they are, handy to give your bike a rinse after a particularly wet ride.
Other wise, good old bucket of soapy water, then dirtworker to rinse it all off. Sorted.
