Hi
Its a Karcher HDS5/11, really is a great jet wash uses standard hose fitting (I use mine off the water butt}
Only 110 pressure but on hot tends to clean most things uses normal diesel car fuel to heat the water.
its commercial grade so for home use should last for years. Aim to pay around the £1200 pound mark.
Bit heavy when full of fuel but fits in the X6 comfortably.
