Prioritize auto-sweeper over dupes to remove ice from ice-maker?

[Gurgel]

I have an ice-machine farm in a hot room. Delivery of water is fine, but the ice needs to be removed via auto-sweeper for it to not heat up too much. It then gets picked up by dupes outside of that hot room. However, time and again, the sweeping gets assigned to a dupe instead of to the sweeper. Is there any way to fix that without some complicated time-based mechanism to block dupes from getting in when the ice is ready, but getting in immediately afterwards to deliver water?

Alternatively, is there some automated way to deliver water to the ice-machine?

If nothing else helps, I will block dupes from delivering to the target containers, but I would like to avoid that.

Sweeping and storage tasks use the priority of the storage. Make sure the storage is low priority and it's the only storage.

Alternatively, don't use any ice storage at all. If there are no storage tasks then dupes will never seek out ice. Sweep the ice and plop it outside on the floor.

The ice machine is deliberately set up to require dupe labor. In exchange the maker gains a small but useful amount of heat deletion. It'll take some experimenting to try delivering huge water bottles to an ice maker area, and to see if autosweepers can use random bottles(seems likely). Keep work efficiency high by building near a water pump, and having multiple ice machines in a row to allow multiple machines to be serviced in 1 task.

@GurgelHow about you let the ice fall through a door in a room dupes aren't allowed with a sweeper inside. Or if you have a second ice storage, set a time sensor thingy and automate the entrance...only green when the other storage entrance is red.

Ie. Dupes can come in but won't carry any ice since the storage is not open...

Just the 2 least complicated options

Make the room 5 tiles high, build a Conveyor Loader in that 5th tile up.  Only the Sweeper will be able to reach the Loader, so Dupes can't interfere with the Sweeper getting the ice out of the Ice Maker.

The trick will be getting the Conveyor Chute or Unloader into the right place and making sure it's much closer to the destination the ice is meant to go.  Probably need to use door permissions on the Ice Maker room to ensure whatever Dupe works at the target location does not have access to the Ice Maker room to make absolutely sure they don't get it wrong.  As they are prone to do.
