This was bought to spray down my cars but is great for clean;ing say my white vinyl fence in the backyard that tends to attract like a moss like growth and the eaves under the house roofs. So it's a versatile cleaner. But mainly i bought it to clean my cars and get that detailer like foam. I use an alkaline cleaner ;for the lower 1/4 of the car including the; rims tires. This will blast the brake dust and grime with the alkaline cleaner to clean the; rims and tires very well. you'll see the brown dirt coming off very easily. I then spray the whole car down with a 25 degree sprayer to get most of the dust off. Then i use chemical guys citrus wash and gloss. The foam sprayer is a little hard to adjust, when i use the middle setting it foams very well but seems to use the soap very fast. But i spray the whole car with this car wash solution and it really foams well. I leave the foam on for like 10 minutes ore longer, if your car is very dirty then i wipe the whole card with a sponge to get all the bird poop dots and things off, but it all comes off easy with this car wash. Then i just wipe down with; a bunch of micro fiber towels and it leaves a great shine. But going back to the pressure washer, the cold water inlet is in the back and you just screw the water hose into it, so make sure your normal hose is in good shape. The power cable is pretty long ;and probably wont need an extension if using for a typical car/truck. The pressure hose just pops in, and the nozzle has like a quick connect to connect the various sprayers and the foamer. the unit will pre-prime when the water is on and you turn it on, so it detects when you press the nozzle trigger and turns the pump on to add pressure and turns off when you let go. it's super easy to use. When done, turn the water off, press nozzle trigger to let all the pressure out, then just disconnect the water hose and you're done., If you spend 10-15 dollars at the gas station drive through washer, i'd say save that money and buy these foaming soaps and this pressure washer and do it yourself. I think comes out better because i can hit the tires and under carriage to clean much better then just the top like the drive through washes. Anyways, works well!
