Rated 5 out of 5 by from Great foam blaster!! I bought this along with my Ryobi pressure washer and I absolutely love it. It has a nice switch to turn off the soap if you just want to use water. Easy to use. Plus when you do use it with soap, it makes massive amounts of foam for your car. I’ve tried using 2 different brands of soap and the Ryobi detergent makes more foam that the other soap I purchased from Amazon.

Rated 3 out of 5 by from Foam Cannon - works good I bought the Ryobi foam blaster along with the Ryobi 1600 electric PSI washer. The combo works good in creating the car foam. I like the wide open bottle, as it makes pouring car soap much easier. However, the bottle size needs to be larger if you have a full size SUV/Truck, as you need to refill several times. I initial got this to wash my 5th wheel RV, so it would be nice to have larger bottle.

Rated 5 out of 5 by from Great to wash cars The soap sticks to the car so you just spray it quickly and use a sponge to cash car. Flip the switch and rinse it. Strong enough to rinse but not too strong to peal paint. It says to use 4 ounces of soap and 4 ounces of water. I used 1 ounce of soap and it worked great. Was able to wash a highlander and 4door tundra with the 8 ounces of soap mixture.
