Mark X (Mark X ) gurgled happily, sounding much like they
were saying:

I notice that Makro are often selling petrol pressure washers cheap.

Is it worth having a petrol version or should I just get an electric
Karcher from B&Q?

Is it a petrol _pressure washer_ or a steam cleaner?

Mate has a big diesel steam cleaner, and it's bloody superb. Still needs
to be plugged into the mains for the pump et al, the diesel heats the
water.

If it's a pressure washer only, then I'd assume it doesn't need to be
plugged in - so the freedom from electrickery might be useful, but you'd
presumably still need a source of sufficient water.
