Mobi Washer V-17
Price: £149.99
AS portable washers use cigar lighter or battery power, they can’t match mains units on power. The Mobi gives more like tap pressure, and while its fine jet can shift mud and light brake dust, it’s best at rinsing, not blasting. You soon get through the 17-litre tank and the 3.2-metre hose is short, but if you don’t have power near your car, this is a decent buy.
