In the last 15 years or so I’ve had 2 OP machines and sold them both. I still have 3 cimex machines, 3 extractors and a
CRB. I had the CX-20 and Orbot and never was able to get the same results as when using my cimex. I really wanted it to work and on paper it would seem like more soil is being removed.
I have some assisted living places I clean that I’m considering trying a friends OP machine to see if anything has changed. These places could benefit from HWE but it just isn’t a good option with trip and fall concerns and open doors, etc.
Over the years I’ve also occasionally used my buffer to do some post bonneting after running the cimex but after a workmans comp claim a few years ago I retired the buffer and now just mainly stick with the cimex as it’s fast, easy and safe and does an amazing job. I’m trying to keep an open mind though with OP cleaning or maybe I’m just a slow learner. LOL
