When you are cleaning the library, the biggest time losses come from carrying too few books, sorting messy piles twice, walking the same aisle again, or waiting on magic at the wrong moment. These tier lists focus on the choices that actually shorten a run.
Ability
Clean The Library abilities decide how quickly scattered books become finished shelves. Sort, Auto-Shelving, Assemble, Shelf Guide, and Insight all save time in different moments, so the best ability is the one that removes the problem slowing your current run: messy piles, slow placement, scattered books, wrong routes, or late misfiles.
Gamepass
Clean The Library gamepasses are worth comparing before you spend Robux because each pass saves a different kind of time: fewer book trips, faster floor movement, earlier ability access, less magic waiting, or smoother badge attempts. None of them are required for a clear, so the best pass is the one that fixes the bottleneck you keep feeling in real runs.
Upgrade
Clean The Library upgrade priority comes down to one question: what removes the most repeated work from your next clear? The best early upgrades cut book trips and pile chaos first, then improve movement, shelf finishing, route help, and late-run mistake cleanup once the library starts spreading you across both floors.
Prioritize anything that cuts repeated trips, reduces sorting mistakes, or keeps magic moving during the long middle and late stages of a cleanup. Carry upgrades, movement speed, Sort timing, Auto-Shelving, and Unlimited Magic start to matter more once the floor fills with mixed piles and distant shelves.
Spend Robux only when a pass fixes a problem you feel every run. A cheap carry pass can beat a costly luxury pass for beginners if it helps every shelf trip. Expensive passes make more sense when you are chasing timer badges or repeating clears enough for the saved time to add up.
Sort messy piles before worrying about smaller tricks. The best abilities speed up the real cleanup loop: pull scattered books together, sort them into usable groups, send them to the right shelf, and finish rows without repeating the same manual placement.
Free upgrades compete for the same early-run attention. Carry keys make every trip better, Sort makes every pile easier to read, sprint shortens long aisles, and Auto-Shelving pays off once books are already reaching the correct shelves.
If you are spending Robux, start with the Gamepasses Tier List. If you are playing free, start with Abilities or Upgrade Priority so you know whether carry, Sort, sprint, or Auto-Shelving will save the next chunk of time.
No. You can clear the library without buying passes. Robux mainly saves time: more carry, less waiting on magic, faster movement, or an easier push toward timer badges.
Clean The Library is still moving fast after the Book Save update. Treat the top picks as the safest priorities now, then recheck before spending Robux or planning a timer run if prices, cooldowns, or pass behavior change.
