Each squeegee blade can be used on all 4 sides. You can use the front side of the squeegee, then rotate, so the back side is facing forward. Once those 2 sides are compromised, you can then flip it upside down, and use both of those surfaces. Squeegee change outs are easy because no tools are required to switch them out. We recommend rotating your squeegees every 20 hours of scrubbing, so they wear evenly.
*Please Note: Any rear squeegees bought for 20" & 24" auto scrubbers with serial numbers before 8000189164 for 20" machines and 8000189411 for 24" machines should purchase the MPVR45195 squeegee. You can order these older model squeegees by calling customer service at 1-888-722-5508.
