My birds are relatively tidy, so it's a pretty light lift.
Every morning I empty and refill their water containers (used to wash those every day, but since they're in the aviary now they don't make a mess in them the way they used to. I wash them every couple of days or right away if one looks/feels less than clean) take out their food dishes and replace them with fresh food.
My birds have a dining/social area that spans most of the width of their cage, made of one pine board over 2 2x4s. I cover the board with a sheet of paper and replace that every morning before I put their fresh food in.
My floor set up is: under-layer of chair mats completely covering the floor under their space, mid-layer of builder's paper, and then a top layer of large sheets of newsprint. Probably every 2-3 days I replace the papers that are under where they usually perch. About once a week I pull up all the top layer and sweep up any stuff that's migrated under the papers. I haven't needed to replace the builder's paper yet. I suspect that'll be something I need to do if I drop a full water dish or something like that.
I also have a table that has some odds and ends (mostly their trove of eucalyptus leaves). I usually replace the paper on that once a week when I replace the floor papers.
They don't mostly poop on their perches so I can't remember the last time I've had to take down a perch to clean it although I do periodically have to flick little deposits off their big manila rope. In fairness to them, the rope is bigger than they are, so they'd have to climb down the side in order to not poop on it. One of their favorite perches is over one of the 2x4s that supports their loft. Since I can't really conveniently take it out to clean, once I noticed that, I scraped it off and then wrapped paper around that end. If something does need to be spot cleaned, if I can do it in place I use their dedicated sponge, a bird safe cleaner sprayed onto the sponge and a lot of water to take care of that.
I don't need to clean or wipe down their cage itself except for sometimes capturing a bit of down that has floated to one of the bars.
At night I empty and refill their water containers and sometimes top up their seed dish if it looks like they're getting low. They do eat their pellets, but somehow they always seem to have enough left to tide them over until morning.
It's probably taken longer to type it than it actually takes me to attend to their needs most days.
