Just order this part for my Dolphin and was wondering what the 2 black rubber triangle pieces are for?

Good day. I spoke to the technicians at Maytronics ( 888-365-7446 ) and was told the the 2 black rubber triangle pieces were for use if NOT using the cartridges. When using a bag they are needed to prevent any lose of suctions, but when using the cartridges, they are not needed.

I have a dolphin pro and I need to purchase the bottom lid that holds the bags, it was damaged. I was wondering if the DX6 bottom lid cartridge would work on my model, or it the bag assembly the best?
Thank you

Is this the spring filter for nautilus plus

This is not the Spring Filter for the Nautilus Robotic Cleaner, you would require these Spring Filters for the Nautilus Cleaner
Reply
What is the difference between the spring filter or the other kind? Does it matter which ones you use?
Thank you for your answer!

Hi Debbie, Maytronic only has one Cartridge for their units. If you have a Matronics/Dolphin cleaner then these are the filters you will have to use. Different manufacturers uses their own type or style of cartridges for their cleaners.

Have worn out several of these cartridges. They are a bit flimsy but work well once installed in the unit.

This is a Godsend...I hated cleaning that darn bag. I still use the bag when I first open, but this was so easy to install and it is so much easier than dealing with the bag. Thanks to Inyo for answering my question about this product so quickly and professionally. You won me over as my first choice for pool products and resources.
