There’s a small amount of assembly needed – certain parts clip on but require screws to keep them in place – but we set ours up in a matter of minutes, thanks partly to the brilliant app, which covers everything from assembly to operation.

Kärcher’s new pressure washer, which has been designed to be used in conjunction with an app, packs a serious punch, and it’s a surprisingly compact package – it’s incredibly manoeuvrable, with chunky wheels and a sturdy reel which prevents time-consuming tangles.

Our favourite bit? The way the electric cable didn’t simply wrap around an external reel but could be stashed in its own enclosed storage space. It’s another pressure washer which doesn’t come with separate wands, but separate nozzles which fit onto the wand’s end – another brilliant space saver. There’s also a smooth extendable handle, and it’s got the next best thing to an internal hose reel – an external one with a metal framework which makes it easy to only pull out the exact length of hose required. Not so with the 130 plus – one of its nozzles has a detergent bottle attached, which can simply be put to one side if detergent isn’t needed. For example, many pressure washers have bulky detergent tanks, even though detergent isn’t always required. This is another incredibly compact pressure washer with clever features which minimise the space it takes up. Our other favourite feature? The internal reel for the hose, which meant no hose-related trip hazards – any excess lengths of hose can simply be reeled in. We also loved the fact that we didn’t always have to replace the entire wand – just the shot glass-size nozzles, all of which are clearly marked with symbols relating to their purpose, and which slot neatly into dedicated holes at the top of the pressure washer when not in use. For example, instead of having a safety catch on the trigger, there’s simply an on/off switch next to it – flick it on and the trigger will move freely, while flicking it off will lock the trigger in place. Many of the features are ones we wish we saw more of. It’s an incredibly powerful piece of kit which is a joy to use (and yes, we did just say that about a pressure washer), thanks to an innovative design and brilliant usability.

Who said pressure washers have to look boring? Nilfisk clearly doesn’t subscribe to this belief – the core 140-6 home pressure washer adds a dash of cheery royal blue to the pressure washer world, although it’s more than just a pretty face.
