We tested 8 electric waterblasters priced from $132 to $944, plus a single petrol-powered model costing $599.
You need the right waterblaster for the job. A smaller machine is fine for cleaning a small patio or path. But for large areas – like preparing a roof for painting – you need a combination of high pressure and a good water flow to do the job effectively.
Our test was of a mix of models: from the serious end of DIY through to lighter models for occasional work.
