I bought this to clean the engine bay in my project car and it did a great job. The soap cannon is great for getting everything soaked and sudsy and the various tips are perfect for dialing in the right pressure.
Next project is stripping the loose paint off my house with the turbo nozzle.
I've never owned a pressure washer and I didn't need anything super high tech or fancy. This was absolutely perfect, light, powerful and easy enough to use even for a newbie.
