Best way to brush main drain during SLAM?

[Momma4]

Any suggestions on how to effectively brush around the main drain at the bottom of the pool during a SLAM?

I've got algae right in the crack where the drain hits the bottom of the pool, and I need to scrub it.

I have a robot vacuum running that kinda has a brush on it, but it's not getting in the nooks down there effectively.

I can't really get the leverage to scrub the drain with the long-pole brush that I do have. The handle is only about a foot and a half above the water when the brush head is down at the bottom of the pool. Best I can do is lay on the diving board and try to maneuver it, but it's super awkward and I don't have much force on the brush.

Any suggestions other than just getting down in there with a mask and snorkel and doing it by hand?

Thanks!!

perhaps you can get a weight on it. 3 lbs or so should help it stay down and maybe be reasonably maneuverable

How long is your pole? Maybe a longer pole will help?

Thank you both!
