Pool Cleaner Climbing Rings for Dolphin Maytronics Nautilus Robotic Replacement Part 6101611-R4, Fits M200/M400/M500, Nautilus/CC Plus DX3/DX4/DX6, Ultimate Wall Adhesion Perfect Match (4 Pack)

Easy to install, I replace at the beginning of the season.

Easy to install, pool cleaner climbing walls better and not getting stuck on main drain anymore.

Super easy to install. Flexible enough to get them where they need to be yet tight enough to stay in place.

Very happy with this product. It is a perfect replacement part. Our robot is running like a champ once again.

Bought these numerous times. I use the M400 quite often, easily 4 days a week. Would recommend to anyone needing these wall climber rollers. Soak a few minutes before installation. They climb like a beast.

Exactly what I needed!

My Nautilus Dolphin CC Plus was struggling to climb the pool walls. Ordering the the Maytronics part was quite costly (plus they charge shipping if minimum value not reached). This came in a few days and was easy to install (plenty of videos). Now the sweep is up and down and doing a thorough job and pool is back to looking great.Note, I did say it's easy to install but if you don't watch the instructions online it will be challenging. You have to pretty much disassemble the sweep and soak the tracks in water to remove the old hardened climbing rings. Don't get frustrated, watch the videos!

The wheels were easy to install the replacements for the machine fit perfectly working we’ll!
