Even though the specification is low, Halfords’ sensibly priced unit came a close third. The design is basic, but the hosepipe attachments were useful. While we would have liked more adjustment, it did a great job of shifting slime. There’s a built-in detergent feed, plus a wheel brush, and a safety catch in the handle prevents accidental triggers. If only there was more storage.
