These worked perfectly.

What you need to know at a glance:REGARDS THE NAUTILUS CC PLUS PRO MODELIf you purchase this product you will be disappointed.+ Easy to install (partly because they are longer/stretchier than they should be)- Poor quality - they are made of harder plastic than the OEM tracks and are too long and stretch- Bought at the end of the 2024 season, we are 2 months into the 2025 season and they are a constant headache- The tracks slip out from between the bearings and get caught up in the pool cleaner's internalsThese are not the replacement pool cleaner tracks you want! They are made of a rubber that's harder than the OEM tracks. They are slightly longer and they tend to stretch over time. It won't be long before they are constantly slipping off of the bearings at getting caught up inside the pool cleaner body, causing your pool cleaner to stop moving. The belts get chewed up and get worse with each failure. I've been very disappointed with these replacement pool cleaner tracks. They last just long enough to not be returnable. There are lots of reviewers who have detailed similar experiences to my own, so consider yourself warned.UPDATE 7/20/24: After weeks of constantly disassembling my pool cleaner to put the tracks back on the wheels, I finally lost patience and purchased tracks directly from Maytronics. The tracks cost roughly twice as much as these. They were more challenging to install because they are tighter, but my pool cleaner is back to full functionality. It runs perfectly and I've not experienced a single issue with the tracks jumping off the wheels or jamming up. This proves beyond a shadow of doubt that these after market tracks are just not of the same quality as the OEM tracks. Save yourself the frustration I've experienced. Don't buy this product.

Bought these to replace the worn tracks that came originally on a Maytronics Dolphin Sigma. Exact fit, and so far (4 days) they work fine.

Like another reviewer I found that the material stretched quickly and they started jumping track causing the machine not to function. Less than a year in and one of them broke in half leaving me to go back to the OEM Parts. Do yourself a favor buy the OEM part up front.
