## Auto-Sweeper

Automates Sweeping and Supplying errands by sucking up all nearby Debris.
Materials are automatically delivered to any Conveyor Loader, Conveyor Receptacle, storage, or buildings within range.

An auto-sweeper's range can be viewed at any time by clicking on the building.

### Effects

Transport up to 1 tonne of resource to a container

### Auto In

**Green**: Enable
**Red**: Disable

## Materials

**Auto-Sweeper** can move items to and from buildings within a 9x9 zone centered on the machine (4 blocks out in each direction). Sweepers can load materials into a building, such as delivering raw food to an Electric Grill then pick up the finished product from the floor and place it in a container such as a Refrigerator in range.

Sweepers obey the priority system, so will move items from low priority containers to high priority containers. This can be somewhat confusing with Conveyor Loaders and Storage Bins since the sweeper will not place anything from the Bin into a Loader unless the Loader has a higher priority setting. The same is true when moving from a Conveyor Receptacle to a Bin, items will be left in the Receptacle causing the conveyor line to back up unless the receptacle has a lower priority than the Storage Bin.

Sweepers are the primary tool for building truly automated shipping systems that do not require any Duplicant labor to carry things around.

## Tips

* Auto-Sweepers consume power only when moving.
* Auto-Sweepers obey sweep designations on items and containers.
* Auto-Sweepers do not exchange heat with transported items.
* Auto-Sweepers can transport up to 1 tonne per swing.
* Auto-Sweepers need to be continuously enabled for approximately 2 seconds per item they attempt to pick up in a single "sweep", and then an additional 2 seconds to store what they're holding. They'll drop their contents from their center tile if disabled after picking up but before storing items.
* Auto-Sweepers can have line-of-sight through diagonal openings and closed Pneumatic Doors. This means that sweepers can transfer items between sealed rooms.
* When Automatic Dispensers are placed between Sweepers it can daisy-chain them into the single sweeping system, where throughput is now limited by Sweeper, which exceeds single Conveyor Rail line in at least x25 times.
* Which tile of a building an Auto-Sweeper needs to cover to be able to deliver to it depends on that particular building, see Tile of interest.
* Auto-Sweepers works immersed in water.
* Auto-Sweepers can plant seeds in Planter Boxes or Farm Tiles (not in regular Tiles) if they are in range.

## Bugs

* Having Storage Bin with a certain selected types of items in the range of Auto-Sweeper sometimes confuses it and it begins loading random items into the Storage Bin. (Last seen in Quality of Life Upgrade Mk III)
* Light's work bonus also applies to Auto-Sweepers.

## History

* **RU-284571**: Sweepers will no longer pick up items through glass.
* **U47-561558**: Auto-Sweeper now uses the new range visualization system.
