One feature of interest is the Plug 'n' Clean detergent system. All you need to do is click-in the detergent bottle and you're good to go. Assembling the pressure washer is straightforward and fast thanks to the 'Quick Connect' system. In terms of accessories, you get two lances (as mentioned), a T350 patio cleaner, a 1 litre bottle of 3-in-1 stone and facade cleaner, two AAA batteries, and a 6 metre long hose.
