Product details

Maytronics 99919116 is the bottom lid assembly with support for Dolphin robotic pool cleaners, measuring 12-1/2" by 9-1/4". It is the genuine factory part.

What is included

The assembly covers all of the bottom lid items except the filter bag. That means the base, two bases for the non return flap, two non return flaps, two springs, two filter bag supports and two bottom lid brackets. Buying the whole assembly saves chasing individual pieces when several of them have aged at once.

Why the lid matters

The bottom lid carries the non return flaps that hold captured debris inside the cleaner once it stops. When a flap tears or a spring loses tension, dirt drops back into the pool as the unit is lifted out, and owners usually blame the bag first. Replacing the lid assembly restores that seal.

Before you order

Dolphin lids differ between models, so measure the old one against the 12-1/2" by 9-1/4" dimension given here. If only one piece has failed, the spring, the flap base and the bottom lid latch are each available separately.

Questions and answers

What people ask about this product, answered by our pool techs.

Does the filter bag come with this?
No. The assembly includes every bottom lid item except the bag, so order the bag separately if yours is worn or torn.

The base, two bases for the non return flap, two non return flaps, two springs, two filter bag supports and two bottom lid brackets.
How do I know this lid fits my cleaner?
Measure the old lid. This assembly is 12-1/2" by 9-1/4", so compare that footprint before ordering.
Can I buy just the spring or just the flap base?
Yes. The bottom lid spring and the base for the non return flap are sold on their own if only one piece has failed.
