I did my first pressure washing on my back patio. It wasn't too badly stained, and I was able to empty the detergent tank completely and then do the washing. (I used the 16.5 rotary surface cleaner.) When I started on my front driveway,I had a harder time gauging when the detergent tank would be empty, and the need to refill the tank with water to rinse it became too time-consuming and unpredictable. I purchased the Westinghouse foam cannon, and have been much happier with the convenience of (a) seeing when the container is empty and (b) simply removing the cannon and attaching the surface cleaner to continue my work. I still give the washer a high rating, but I would suggest improvements on the detergent dispenser. A clear window showing how much detergent is left, combined with the ability to simply close the connection to the detergent tank to continue washing would make the built-in detergent dispensing usable.
Easy to assemble. Used it to clean off back yard concrete patio, it removed dirt and leaves with no issue on the first passthrough using the 25° nozzle. I will make the second passthrough with the 15° to get a cleaner look.
I used my power washer yesterday for the first time. I live on a busy road and the house gets covered in grime. The dirt washed away easily. Then I took it to a stone wall and the turbo nozzle took away years of moss, algae and dirt.
