I used the CPS-100 with a light blue tip for 3 years and it worked fine most of the time. There were a couple of times a year that it wasn't able to get the road film off. After I worked with CSI on their new setup, I was able to get the road film off during one of the challenging times. Then I started running our current
JBS setup and got slightly better cleaning than I got with CSI. The difference was minimal and with salt and pollen season starting I had to quit testing with CSI. I have run the CPS-104 and CPS-105 setup for 6 months now and it has worked extremely well so far. My only problem with
JBS has been their soaps tend to partially clog the metering tips, but I switch out tips each month and soak the old ones to clean and reuse them. This seems to have helped with this issue.
