I have that washer and it's great. Except for the hose, it is absolutely horrendous and bendy, probably ok to wash patios with it but that's about it.
Get one of these bad boys for it if you plan on using it to wash the car: http://www.ebay.ie/itm/NILFISK-C110-3-5-X-TRA-C120-RUBBER-HOSE-1-WIRE-10-MT-/170552136580?pt=UK_Home_Garden_PowerTools_SM&hash= item27b5b31384
Costs as much as the washer but it's totally worth it if you want a proper job
