Triplewax Extendable Water Fed Wash Brush

Best price: £36

This 1.7-metre extending brush had the design features of our Sealey Best Buy, but not the quality, despite being the priciest on test. The on/off water control switch worked inconsistently, with water pouring out of the extension, and it became difficult to extend the brush while the water was switched on. The wide brush covered body panels well, yet the head’s connector wasn’t stable, as it spun around and made the brush unwieldy.
