Maytronics Maytronics Dolphin Brush - Climbing Grey (2 Pack)

This appeared a little daunting to install at first but then I got the same small needle nose pliers I use on my tennis racquet stringing machine —about 4.5 inch Tecton needlenose pliers to pull the runner comes through the holes . Did one or two on either end and then one in the very center and then worked until completed. The pliers were essential and then you need to grab low on the “cone” once you get it through the hole lest you snap off the top part od the runner cone. (I did snap off off the top of a couple cones before I got the hang of it but they were still usable but harder or pull through the hole.

The media could not be loaded. This 2 pack is a awesome fit for my Shark pool vacuum M#RC9990CUB. Easy to replace (Have some needle nose pliers handy).

Due to us having a border collie who "herds" the pool cleaner and bites at it when it comes up the side. We have had to replace the pads 6 times so far. It's easy to replace the old ones since I have had a lot of practice! only wish they sold them in a 12 pack !

This is exactly what I needed. Just know if you order this and you live in Texas, the shipment went from NH (origin) to Texas by way of Anaheim, CA. So don’t be in a hurry for this item.

The description said it fit the s300 but it they don’t. We have a Doheny’s Dolphin Mercury which is the same as the s300 and some others but these are not correct for those models.
