Question on bottom drain and pop ups

I have a pop up system and bottom drain. High winds put a lot of leaves in the pool. the bottom drain does not seem to be working.

How can I clean the bottom drain unit? I have cleaned all above ground filters but pool is not self cleaning.
What are the steps to increase suction or cleaning power with bottom drain system?

I added a picture of bottom drain.

many thanks

ps I just uploaded a video link to be used later, when i have more questions:)

Are your drains plumbed to a leaf canister or are they plumbed to the suction side of the pool pump?

i think i figured it out. the valve below the skimmer basket was fully open thus not allowing any suction on the bottom drain. once I closed the valve below basket things started working again.

my goal is no more pool guy by the next 30 days .....saving 70 per month:eek:
