4 Pack Climbing Rings Replacement for Maytronics Dolphin Robotic Pool Cleaners, Compatible with Dolphin Nautilus CC Plus M200 M400 M500 DX3 DX4 DX6 Sigma Premier and More (Part Number 6101611-R4)

The old rings wore off, affecting the performance of the vacuum. These rings work perfectly. Very happy with the purchase.

Super easy to do yourself.

I removed my old rings and placed the new ones in its proper location. It has worked perfectly for three months. I did purchase a second set as a backup because they do wear out. I recommend this item.

Our Dolphin Endeavor is about 5 old and is still going but is in desperate need of a new set of tires. Install was easier than expected and I was cleaning my pool within minutes. I hope to get another 5 years out of my robot!!

Perfect replacement. Easy to install.

These worked like a charm. Old ones fell apart after years innthe salt water. These have brought new life to the pool cleaner.

Last almost a year on all tile pool. When one goes you might as well replace all. Its a chore to get them on

The originals lasted 4+ years, but these replacements only lasted 1 year. Not sure if it’s because of my usage as I left the machine in the water for longer periods of time, but I am not going to purchase these again and will order them from a different vendor. They did their job but they recently became mushy and broke off easily. See picture.

Good replacement for the Dolphin M400

Just as good as the original part at a fraction of the cost.

Had i known i would have bought those from the original company.

The rings were slightly too big and rubbed against the main body of the unit.
