Halfords HP150
Price: £129.99 Motor: 2.3kW Flow: 420Ih
New for this year from the car accessory store giant, the HP150 is, not surprisingly, designed with vehicle cleaning in mind.
It comes with an in-line detergent bottle for shampoo, plus a rotating brush. You can also adjust the power of the motor to match the job, making shifting stubborn stains without damaging bodywork easy. A great performer.
