The Bosch Fontus Gen II Cordless Pressure Washer is a cleaning tool which is pulled along rather than lifted, alleviating the weight and letting you use it comfortably. It features a 15L water tank which is much larger than other pull-along washer tanks. This model also includes a SmartBrush for larger surfaces such as garden furniture and features sturdy wheels, an extendable handle, adjustable pressure modes and 4 spray patterns.
