Pump help

Hey guys, growing in 5 gallon stand alone buckets. It's too challenging in flower trying to remove the lids to do water changes, what is a pump that can siphon the old water out and put new water back in? Links would be awesome or exact thing to look up. Lol

Search for battery syphon

I use them, but in late flower it's hard

Lift lid/plant off bucket onto another bucket, empty, remove old bucket, clean and refill, out back
Lift lid/plant back onto bucket
