1,247 W of rated hydraulic power and the only induction motor in the panel, often described as more durable than a universal motor. At 18 kg this is a machine you wheel, not one you carry.

Choose it if

  • Long, frequent sessions, where the motor type matters.
  • A machine that lives in the garage and moves on its wheels.

Skip it if

  • Weight: 18 kg, twice the comparison average.

Before you pull the trigger

  • Never at a person, an animal or electrical equipment. A jet above 100 bar can pierce skin and inject water beneath it: that is a medical emergency, even when the wound looks small.
  • Eye protection and closed shoes. The jet throws grit, joint fragments and moss up to face height.
  • Never on old fibre-cement roofing or cladding. Older sheets can contain asbestos, and high pressure releases the fibres.
  • A socket protected by a 30 mA RCD, an outdoor extension lead fully unwound, and connections kept out of puddles.
  • Render and timber: try a hidden corner first. Old render, crumbly pointing or soft wood erode quickly. Keep the nozzle back and start with a wide spray.

Frequently asked questions

Where does this machine's score come from?

It is calculated, not awarded. Five measurable criteria are weighted, and each value is mapped onto a scale relative to the other machines in the comparison. For this machine, 100% of the scale could be applied: criteria the maker does not publish drop out rather than being replaced by an estimate.

How much pressure does a patio or a render need?

Look at rated pressure and flow rather than the box figure. For a slabbed patio or a render, rated hydraulic power of around 1 kW, for example 110 bar at 330 l/h, does a clean job; below that, the machine suits garden furniture and bikes better. On render or soft timber, nozzle distance matters, not maximum pressure.

Can a pressure washer work without a mains water supply?

Yes, if it can draw from a tank: most of this panel can, up to 0.5 m of lift, with a suction hose fitted with a filter. That helps on a plot with no connection, using a rainwater butt. Each machine's page says whether the maker publishes it.
