Fitted with electric key-start, this pressure washer is so easier than ever before to get started. It even has a back-up recoil pull-start should you ever need it for added reliability and also ensures you can always get the job done.

The large 5.5L fuel tank can be filled with red diesel which is significantly more cost-effective than standard road diesel and fuel consumption is an economical – 1 to 1.5 litres an hour.

Industrial Pressure Washer

Hyundai diesel jet washers use industrial-quality Annovi Reverberi (AR) high pressure pumps on their engine driven pressure washers to ensure maximum performance and longevity. Annovi Reverberi (AR) is one of the world leaders in pressure washer pump manufacture.

Both the pump and engine are mounted on a heavy-duty anti-vibration rubber mounted subframe to mimimise noise output and increase stability.

Portable Pressure Washer

Weighing 135kg, the HYW4000DE is built with a heavy-duty powder-coated tubular steel trolley design frame, with its large, ergonomic handlebar making it very easy to move around.

Fitted with four wide, large-diameter foam-filled puncture-proof tyres, these make this powerful diesel pressure washer very easy to move around, especially across rough and difficult terrain such as muddy fields and stone driveways.

The built-in hose and lance gun holder will help keep everything organised when moving between jobs, and also makes it convenient to store all together.

The quick-release couplings on the pump, hose and trigger gun allow you to quickly fit everything together to get started on the job at hand and also to add additional hoses as required.

The HYW4000DE is a cold water pressure washer that is used with mains water or can also be gravity fed. It is able to draw water uphill 1.5m, allowing water to be taken from a water butt – no need for an outside tap, making it ideal for use during hosepipe bans.
