Made in Germany for over 70 years, Kärcher strain washers are ten instances extra searched-for than the following hottest model. They vary from the moveable K2 Compact (reviewed beneath) to this large, heavy and really highly effective K7, which have to be considered the large daddy of home strain washers – though it’s not essentially the correct selection for everybody.
The heavy weight comes from the motor and parts wanted to ship the immense 180 bars of strain. I discovered it very tough to manoeuvre on its two wheels however as soon as in place, it may well largely sit in a single spot – the strain from the top of the 10m hose is excessive sufficient to wash giant areas of decking or patio extraordinarily rapidly. I attacked a decades-old, grime-encrusted backyard desk for simply 20 seconds and it got here up trying model new.
The wand – though you could desire to think about it as a rifle – has three nozzles which you twist to pick out: a low strain spray for making use of detergent, a excessive strain, spinning ‘dust blaster’ jet (you’ll use this with the patio cleaner attachment) and a ‘vario’ jet which helps you to select between six settings for various jobs like decking, paving or automobile cleansing. There’s additionally a Enhance perform which provides an additional 15 bar for 30 seconds. It’s like getting a power-up on Mario Kart.
The K7 together with different fashions on the high of the Kärcher vary comes with Good Management, linking it to a telephone app. Being previous, I’m usually towards that sort of factor however this app is useful. Inform it what you’re cleansing – automobile, bike, wooden, glass, stone and so forth – and it’ll let you know what attachment and what settings to make use of and find out how to get the very best outcomes step-by-step.
A foot-wide patio cleaner attachment is included within the field, together with a bottle of patio detergent which slots neatly right into a feeder dock on the primary unit. Collectively they’re a formidable drive. Each sweep of the round cleaner head reveals a foot of glowing recent decking or paving, like waving a large magic wand – simply be sure there’s someplace for the soiled water to run off onto.
Once you’re accomplished the hose winds up, the facility wire suits in a mesh bag and the lance slots right into a clasp. It’s all very neat: solely the large patio cleaner head doesn’t have a slot. So though it’s a giant unit, the K7 doesn’t take up an excessive amount of house within the storage.
In all honesty, a much less highly effective Kärcher like their 145 bar K5 or 130 bar K4 is sufficient for many family jobs and a few come bundled with delicate car-cleaning attachments, which this doesn’t. However I needed to make it the general winner as a result of, for anybody asking “what’s the greatest strain washer?” that is it.
Additionally, in all honesty, as a result of I’m hooked on the facility. They are saying that to a person with a hammer, each downside seems to be like a nail. The identical with the K7. Give it per week and there received’t be a single factor in your backyard you haven’t blasted and also you’ll be knocking in your neighbour’s doorways asking to do theirs.
