Yes stoll available to buy, John sells them. As said I'm not wanting to get onto the hard floor cleaning scene, zI was asked by a new customer to jet wash the patio but it was just like rinsing it with a garden hose. I will mention it next time I go to do the windows and see if she wants to hire the machine for themselves, but dont want to take the job myself as I have no idea how the tiles will look afterwards.
