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

A  Answered on 8/25/2015 by InyoPools Product Specialist Brian M.

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

Dwight,The correct bottom lid assembly for the Dolphin Pro cleaner is part #  3295-180 and can be seen HERE.

Is this the spring filter for nautilus plus

A  Answered on 5/25/2016 by InyoPools Product Specialist Patrick P.

This is not the Spring Filter for the Nautilus Robotic Cleaner, you would require these Spring Filters for the Nautilus Cleaner

What is the difference between the spring filter or the other kind? Does it matter which ones you use? Thank you for your answer!

A  Answered on 6/4/2016 by InyoPools Product Specialist Lennox H.

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.
