amazing pressure washer, as the home depot video explains for pressure washers you need to pull the top of that gold nut down to insert eh nozzle, make sure you do that otherwise, it will require force to slide partially in and leak and make you think there is something wrong with the unit. it works wonders at 2-4 mm away from concrete to remove paint and graffiti etc, to whiten garage doors made grey by dust, etc. red nozzle 0 degrees is for really hard to remove paint, used 3 mm above ground, while the other ones, 10,25 and 40 degrees are for progressively easier to remove paint. note that the white one is ideal for easy-to-remove paint on concrete, since it removes an area 5 times bigger than red one however, for tough paints it won't work. none of them remove paint on concrete if you don't use it ultra close to concrete. So it works better than you expect and it is cheap. i paid 101 for this, it was on sale, a great deal. home depot asks 60 dollars to rent a gas-powered one for 4 hours. this one you have it for a lifetime. cleans tire marks from concrete fast at a distance of only 2 inches, so it can swipe them fast. swing it in a direction 90 degrees perpendicular to the triangle formed by the jet to remove stuff fast. garage door dirt is removed only if you are 1 cm away. Amazon has other cheap ones, so yes, this is my first ever pressure washer, and man, it's amazing, being electric, amazon has other models of 100-120, so give it a try, make your house look amazing, remove dirt paint, concrete tire marks, etc. wash solar panels, etc.:) This is a must for every home owner, you can wash stucco, rugs outside, etc, you name it.
