turbo beat me to it...
I bought one of those with a copy Honda engine for use around the farm......£160-170 over 10 years ago....still starts 2nd pull.....
the reason I bought it, I bought a Kacher and the pump went just outside of the warrenty....
A new pump for the petrolmachine was £60.....never needed one....

I have a customer that uses a generator to run a single phase steam cleaner as the power supply they have is rubbish. They have a 6KVA generator and it seems to cope with that ok but I think there machine has a slightly smaller motor so wouldn't like to say a 5KVA would run the motor you have.

I have a 5Kva Robin
diesel/Markon (alternator) generator that happily starts and runs a 13cfm 3hp motor direct drive Aldi compressor. The genny loads up a bit when the compressor starts up, but never bogs down.
A petrol engined generator may bog down a bit more due to the engine having a bit less rotating mass, possibly...

I have 3 petrol washers but i like options as an electric washer from a 3hp motor is much more silent and civilised doing work at the weekends. Have the generator in the van 50 meters away and all is good. Thanks for the replies so far guys, all taken on board
Near enough the washer motor is 3kva. Being a DOL motor you're looking at maybe 6x or more that on startup - so a wee 5kva portable you'd expect to make a noise like a pig swallowing half a cabbage... and fall over.
You can find with pressure washers on gennys... that when you initially first pull the lance trigger it fires up OK. This is because the impeller is able to build pressure so the motor starts with little load.
Once up to pressure & you release the trigger, and then press the trigger again..... & the genny nosedives - due to the much higher water pressure now in the machine.
A 5kva 1500rpm Lister might do it - but that's because it's git a lot of stored energy in a hefty flywheel, which means they punch well above their actual HP with impact loads like motor starts (& have much better alternators that can sustain overloads without the voltage collapsing
