Upgrade
Movement Speed Tier 1
Updated:
Priority 2 upgrade — Cut travel time between departments
Overview
Movement Speed Tier 1 is upgrade priority 2 in the recommended Clean the Supermarket purchase path. It belongs to the speed progression category and is what most veteran sorters consider an opening-loop essential.
Per the canonical /build/upgrade-order/ reference, Movement Speed Tier 1 works best when paired with the upgrades from the same category and category-adjacent ones — for example, Carry Capacity Tier 1 unlocks the math behind Carry Capacity Tier 2, while Movement Speed pairs multiplicatively with any carry upgrade. There are no prerequisites — this can be your first purchase.
In effect terms, Movement Speed Tier 1 cut travel time between departments The currency to purchase upgrades comes from shelving items, so progress is sequential — clear, earn, upgrade, return faster. Carry and Speed are the core front-loaded categories because they directly compound the time-to-shelve ratio; automation tools like Auto-Shelve and quality-of-life perks like Pickup Range only justify their cost once your base loop is already efficient. Movement Speed Tier 1 fits into this progression at priority slot 2, which is exactly where most run-optimized loadouts place it.
Movement Speed Tier 1 is the canonical second purchase, paired with Carry Capacity Tier 1. The combination is so foundational that the upgrade order rarely deviates: Tier 1 carry first, Tier 1 speed second.
Speed Tier 1 specifically cuts the time between A1 and A4 (the perimeter loop) by roughly 25-30%. The exact percentage depends on your route efficiency, but the documented impact across veteran completion runs is consistent: Speed Tier 1 saves more wall-clock in the perimeter aisles than any other single upgrade.
Per the canonical /build/upgrade-order/ reference, Speed Tier 1 is also the prerequisite tier-base for Speed Tier 2 and Speed Tier 3. Skipping Tier 1 to buy a different upgrade locks you out of the entire speed progression tree for the rest of the run.

When to Buy This Upgrade
Buy Movement Speed Tier 1 as one of your first 3 purchases.
The decision rule is: never buy automation or utility before basic capacity and speed are at Tier 2+. Movement Speed Tier 1's priority slot of 2 means it comes before any automation purchase. If you skip Movement Speed Tier 1 entirely, the run still completes — but you'll spend roughly 20-40% more time per aisle once stretching shelves kick in. Most stretching-shelf strategies assume Carry Tier 3+ and Speed Tier 2+ are active by the time mid-store aisles (A4-A6) appear in your run.
Prerequisites: none — buy whenever currency allows.
Buy this immediately after Carry Tier 1. The pair forms the baseline of every veteran loadout.
If you skip it: Carry Tier 2's purchase math breaks because you'll spend the extra trips walking instead of sorting. The compound effect is that your mid-game currency accumulation slows and you reach the 50% completion milestone roughly 15-20% later than a Carry+Speed-paired run.
Tactical note: Speed Tier 1 has its biggest impact on A3 (Dairy back wall) and A4 (Frozen) because those are the longest travel distances from the central cross-passage. Don't skip Speed Tier 1 if you plan to clear the cold corridor early.
