## Questions & Answers

**Q: How often should the filters be cleaned?**
A: Depends on usage and how dirty your pool is.  If you leave this in the pool, once a week should suffice, as long as there is not a storm that drops debris into the pool.  I alway spray off the filters when I take the cleaner out of the pool.  Having them dry with dirt/sand in the filters decreases useful life.

**Q: Are these compatible with the Nautilus CC Supreme?**
A: Yes they are.

**Q: I have a Dolphin Quantum. Will these fit?**
A: No, it won't. We check your model and found these two part number will fit your model: 9991463-R4 and 9991458-R1.

**Q: Will this fit dolphin E10?**
A: No, it won’t, compatible models are: Dolphin Nautilus CC Plus (Not for Nautilus CC), M200, M400, M500, M4, M5, Sigma, Odyssey, Oasis Z5i, Oasis Z5,Triton Plus (old), Aquarius XL, Liberty, Wave 65, Wave 90, C3,C4,Bio; Part# 9991432-R4
