The game officially tells players to buy and upgrade tools to clean faster. It does not publish a public catalog of names, prices or stats, so this page gives you a fair test instead of a made-up table.
A repeatable observation is more useful than a generic best-tool claim.
Step 1
Choose the same reachable patch or an equally dense visible area for both samples.
Step 2
Record progress gained and elapsed minutes before buying or changing the upgrade.
Step 3
Repeat the same sample, enter cost and balance, and compare the measured speed change.
You have a name or cost but no equal before/after sample yet.
Your after rate is higher. Judge the size of that gain against the cost and run goal.
The sample is flat or slower. Repeat before treating noise as the upgrade's true effect.
No attributable public tool-name catalog was available at the August 12, 2026 check.
No exact prices or stat values are claimed because the official public description does not publish them.
Record equal-length before and after progress samples, then use the Upgrade Planner to calculate observed speed gain and affordability.
There is no attributable universal ranking. The useful answer depends on the improvement you observe, the cost you see and the current timer pressure.
