Can anyone recommend a petrol pressure washer for the van at track days?

I'm currently looking through a few and I'm trying to do my research so I can buy the right one for me, what kind of petrol pressure washers would you guys recommend and what one's would you stay away from? I'm wanting one for the van so I can give the bike a decent first clean before I set off home and would be drawing water from a water barrel.


Based in the UK so brands that are familiar to here would be nice.

Any help would be greatly appreciated, thanks.
