After much deliberation ("I need a pressure washer!", "No, you just do it with the garden hose.", "If only I had a pressure washer", etc) bought this pressure washer as a second chance. I want to use it mainly for car and mountain bike.
The accessories that come with it seem super handy, but in practice this is disappointing: the foam sprayer eats through the cleaning agent (3/4 of the bottle of car shampoo for one wash of a not very large car), the washing brush is not useful because it is attached to the spray gun, and the patio cleaner is not super powerful and can only be used for mirror-smooth surfaces, otherwise it will get stuck behind every stone.
But! The dirt blaster is really great, thick encrusted moss and algae growth on concrete tiles flies off, weeds growing between the tiles are made short shrift (be careful not to spray the sand between the tiles #BeenThereDoneThat).
The spray lance is useful for rinsing cars and bicycles. Even in the most powerful setting, it's not as powerful as the dirt blaster, but that's for the better, or you'll be squirting the grease out from between your bearings. The "adjustable water pressure" is a fairly simple system, it is not a setting on the device itself, but a matter of turning the spray lance more open or closed. The dirt blaster has no such thing and therefore always works at the same power, there is nothing to control.
It is ideal that the device is quiet when you are not spraying, but in any case it is not a huge noise.
