Pressure Washer Recommendations?

I am looking to buy a pressure washer initially to blast clean a rough concrete patio slab laid last autumn, now looking sorry for itself. Also to clean the watermarks off quarry-bought sandstone prior to laying. I individually scrubbed clean nearly 100sqm of this sandstone last year (now looking beautiful throughout my ground floor) but it nearly broke me. Adjustable pressure useful as I will need to be gentler with the sandstone than the concrete.
Karcher is big in my local diy superstore, but I am not sure what wattage/bar pressure to buy. I don’t want to spend a fortune but if I buy just the compact version and it’s not powerful enough I will have wasted my money. Happy to consider other brands, can get off a****n
Any recommendations or advice gratefully received!

It does the job as well as the fancier, cylinder type model we had before and which had 3 or 4 heads. That lasted about 10 years before it died but the simple one seems to work well for me.
i think next time we will get the K4, bit more oomph! We have no water pressure here, we have our own pumping station but even so, the karcherK2 does very well.
My mum's neighbour regularly pressure washes his concrete path out into the street and when I dismantled a huge wooden planter last year I was shocked at the difference in the surfaces between covered flagstone and non-covered (pressure hosed) flagstone! These are olde stylee street flags so very robust. Needless to say the rougher surface goes green and dirty much faster!
I do use a Karcher but only very judiciously now.
I hope you can see. I've put a little stick at the interface.
I've even had to get it looked at under warranty and that was a simple process with a local agent taking it in for servicing.
Our water pressure in the outside tap near the patio is extremely strong so might have to experiment with that and start with the tap half open, so I don’t blow up the pressure washer!
The concrete is roughly finished, Plant Pauper, it won’t be seen and a good key for the flexible adhesive is essential so the rougher the better. But the sandstone slabs are honed and I really don’t want to wreck them so very many thanks for the warning, I will take extra care with them.
Excellent, I love getting new toys
When my neighbour had her driveway professionally done, they also used the patio brush.
