The catch
Karcher K1800PS Cube Electric Pressure Washer
With a 20-foot hose and a cube you can only carry, it needs more repositioning than a wheeled model.
Side by side
Karcher K1800PS vs K1700 Cube guide: K1800 raises pressure and keeps the foot-switch cube layout
Quick verdict
Go with the K1800PS by default. It has 100 PSI more and keeps the foot-switch cube format and the light carry weight. The K1700 is still enough if your whole workload is an occasional car or some furniture.
