Choose the upgrade that fixes your bottleneck
“Best” depends on what ends the current run. Test the same dust patch, base route and starting cash, then change one upgrade only.
BRUSHCollection speedMeasure how long the same patch takes to clear and whether the tool reaches the next area.
CANISTERCarry capacityCompare fewer returns to base against the upgrade cost and route distance.
SPEEDTravel timeMeasure the full sweep-to-base loop; movement speed matters only if it shortens a repeatable cash run.
How to record a real order
- Write the current tool levels, cash, clean percentage and server date.
- Run the same dust patch until the canister is full, then record the return time and payout.
- Buy one visible upgrade and repeat the route without changing the party or machine state.
- Compare cash per completed loop, not one large pickup or a single animation.
- Recheck after an update because an incremental game can rebalance cost, capacity or speed.
EarlyWiki will add named level costs and a recommended order only after the live UI and repeated runs provide a stable table. Until then, the test method answers “what should I buy first?” without pretending a universal order is official.
