Challenge Xtreme
Price: £39.99 Motor: 1.8kW Flow: 360 litres/hour
A top cleaner, but it sure did shout about it! The Xtreme is so noisy, any prolonged use would annoy the neighbours. However, the unit cleans well, with excellent nozzle adjustment ensuring it blasted the toughest grime. There’s no storage for the two wheel cleaning brushes, but it has a built-in detergent bottle, and is good value.
