What are the main features of the Greenworks G30 pressure washer?

This is a solid, sturdy pressure washer with a 1500w engine, a water flow rate of 400 litres per hour and it delivers 120 Bar of pressure. It’s one of the heavier washers in our tests but wheels make it easy to manoeuvre around the garden as does a trolley handle, which slots down into the body of the washer. It comes with a choice of two nozzles, a variable power spray and a turbo spray, plus there’s a foam sprayer bottle that attaches to the lance, a wash brush and a patio cleaner. There’s also an extension lance and it has a good six metres length of hose. Onboard storage on the body of the machine helps keep the cable tidy and out of the way and is useful for stashing the extra nozzle and detergent bottle.

What’s the Greenworks G30 pressure washer like to use?

Almost ready to use, only the wheels need attaching to this pressure washer, but they require a screwdriver and are a bit fiddly to get on. Once up and running it feels robust and solid and the washer is steady on the ground and doesn’t fall over in use. The six metres of hose are handy for stretching around furniture and cars or across patios and the extension arm is great for giving extra reach and making long jobs less back breaking. It’s a little tricky to connect the two nozzles but they clean effectively and fast. The patio cleaner is also good, removing dirt from surfaces without spraying grime and filthy water everywhere.
The trolley handle is particularly useful, moving up and down smoothly and the large wheels make this an easy to move washer, despite its weight.

What situations is the Greenworks G30 pressure washer most suitable for?

This sturdy machine is great for cleaning cars and in our test, it made light work of neglected, algae covered garden furniture. The turbo spray is great for blasting into stubborn nooks and crannies on decking and paths. The patio cleaner works well on surfaces, although it takes a couple of passes to get them really clean. If storage space is an issue the trolley handle allows the washer to be easily tucked away after use.

Is the Greenworks G30 pressure washer good value for money?

This comes with useful accessories and features. It feels robust and well made and it cleans quickly. It comes with a three year warranty and we think it’s excellent value for money.
