Difference Between Karcher K Ranges

Can anyone explain in the simplest way, what is the main difference between the series of Karcher Pressure Washers? Ie, what defines a K2, a K4, a K5 etc.... (there are then so many options within each series)....

Edit, I've just found this article, would this be a fair description for each?

Size of machine, power output and flow rate and how the pump is cooled - air on lower spec machines and water on higher spec.

Then you’ve got storage, ease of movement of the pressure washer, length of hose etc..

Mrs Cooks and Cookie Youngster bought me a K7 last Christmas. It's brilliant. The cable and hose storage are really excellent, and the lance holders work perfectly.

I'd happily buy one myself, if I was looking again.

I upgraded from a K4 to a K5 and cannot recommend highly enough, it may only seem like a small upgrade but i've found it so much more effective during the rinse stages

Was looking at the Karcher range again last night. I helped the neighbour with his car at the weekend, and despite "only" having a K2, the pressure felt a little better than my Nilfisk.

I was looking at K5 and K7. Just hard to justify the cost of a K7 TBH.

I got a manufacturer refurbed k4 full control on an eBay site with the 2 wands and a years warranty for £84 last week to replace my 7 year old k2. Arrived well packaged and no scuffs etc maybe worth a punt if you are looking at a new one or the outlet do them usually for around £100.

My old k2 had more power than my k5, I keep the nozzle from my k2 and use it on my k5 instead of the one that came with it and it has a faster flow.

Have been thinking about upgrading mine. Started looking when we had threats of hosepipe bans and one thing the K4 upwards offer is the ability to draw from non-mains source such as a water butt. I don't have a water butt at present, or anywhere to put one but thought it might be useful as I could get round the hosepipe ban by filling a wheelie bin using buckets, transport it to nearer the car then use the k4 to wash from there.
Don't know exactly what cleaning power it would give but gets round the ban so gives me an excuse to spend money on the hobby.

Surely there can't be any threats of a hosepipe ban at the moment? It is just about the wettest England has ever been isn't it?

But on subject I have a K7 albeit the older style one and would recommend it to anyone! Lovely having the adjustable pressure and it just feels like it isn't even working hard. My old K2 sounded like it was working at its maximum the entire time.
