Sweep The Moon Upgrades Guide

Cash disappears fast in Sweep The Moon if you buy every shiny shop tier the moment it appears. Upgrades are the difference between a painful toothbrush slog and a session where canisters fill on purpose and robots start earning while you explore. This guide ranks brush, canister, and move speed, walks through the proven early path (Dustpan Brush → 6KG canister → Robot Dock), and explains when to stop upgrading tools and pivot into Vehicles or Robots & Automation.

If you still need the sell-loop basics, read Getting Started first. For turning upgrades into maximum income, pair this page with Earn Cash Fast. Class discounts and pass value live on the Tier List Hub; codes status stays on Codes.

What each upgrade actually buys you

Brush power raises how much dust you clear per swing or per second of contact. Weak brushes feel like painting the Moon with a cotton swab—tiles take forever, and you return to base with almost nothing. Stronger brushes shorten time-to-full-canister on dirty ground.

Canister capacity raises how much dust you store before a mandatory sell trip. Tiny canisters force constant base runs; oversized canisters waste money if your brush cannot fill them. Match capacity to brush strength and to how far you roam.

Move speed cuts travel time between dirty tiles and base. Speed does not clean faster by itself, but it multiplies every other upgrade by reducing empty walking. Strider Class rolls (+0.56 m/s at common rates) and Fast Legs (99 Robux) rhyme with this idea—they are not required on day one.

Ignore cosmetic flex until the productive trio feels comfortable. A prettier brush that barely cleans is a trap.

Early path: Dustpan Brush → 6KG → Robot Dock

Community-tested openers converge on the same spine:

1. Dustpan Brush — the first meaningful jump off toothbrush-tier clearing. Buy it as soon as you can after a few honest sell cycles.
2. 6KG canister — enough capacity to leave base, clear a real cluster of tiles, and return without living on the sell pad.
3. Robot Dock — your on-ramp to automation. Place it, then connect Robot Dust Out → Belt → Base Belt In so bots contribute cash without babysitting.

Why this order? Brush without capacity means you still sprint home every minute. Capacity without brush means a big empty tank that fills slowly. Dock without either means robots starve for a player economy that cannot fund belts, splitters, or extra docks. Nail the two tool upgrades, then spend the next cash pile on the dock and its belt line. Build Mode is key 2; building menu is B—muscle-memory those before you panic in placement mode.

After the dock works, revisit brush and canister in smaller steps while you fund belts, solar, and maybe a second dock (+1 Robot Dock pass exists at 149 Robux if you prefer paying). Wiring mistakes and splitter layouts belong in Robots & Automation, not in panic rebuys of the same brush tier.

Mid-game: robots versus vehicles versus more tool tiers

Once Dustpan + 6KG + Dock are online, every cash decision is a fork:

• More brush / canister if you personally still spend most of the session hand-sweeping and hitting capacity caps.
• Belts, splitters, solar, extra docks if robots idle, belts jam, or power is the bottleneck.
• Sweepers, rovers, or UFO mobility if the map’s dirty frontier is far and walk time dominates. See Vehicles for charging and pass notes (Fast Vehicles 149, Head Start 199).

A practical rule: if your canister is full before you are bored of sweeping, raise capacity or sell-as-you-go options; if you are bored because tiles take forever, raise brush; if you are full of dust but hate the hike, buy speed or a vehicle; if hand play feels solved, invest in automation throughput. Do not buy a rover to fix a weak brush—you will only tour the Moon slowly with an empty-looking canister.

Brushwright Class (~9% spin rate) adds about +10% power and +25% tool shop discount, which makes continued upgrade shopping cheaper. Packer (~24.9%) adds carry weight; Broad Sweep (~13.9%) widens the head. Those spins support the upgrade plan—they do not replace it. Spins cost 50 Shards at the Classes shop; read odds on the Tier List Hub.

Passes that interact with upgrades

Optional Robux purchases change the math but not the order:

• Infinite Canister (99) — removes the capacity ceiling so brush and route quality matter more than tank size.
• Sell As You Sweep (249) — softens the base-trip tax; still worth owning a strong brush.
• 2x Cash (249) — doubles the value of every upgrade you already bought; best after you know what you are doubling.
• Everything (649) — bundle convenience, not a skill substitute.
• Fast Legs (99) — speed when you still walk most routes.
• +1 Robot Dock (149) — parallel automation once one dock is proven.

Buy passes only after the free upgrade path makes sense. A 2x Cash pass on a terrible route still funds bad habits. Optimize with Earn Cash Fast, then decide.

Shop discipline and co-op spending

In co-op (up to four friends), agree who banks upgrade cash versus who places shared docks. Duplicating three mediocre brushes while nobody funds a belt line is a classic fail. One player can specialize in shop progression while others clear tiles to feed the treasury. Empty at base often so cash enters the pool instead of sitting in full canisters mid-map.

Track clean percentage as your north star. Upgrades exist to raise tiles cleared per minute across the whole squad, not to max a single stat bar for screenshots.

Common upgrade mistakes

• Skipping Dustpan or 6KG to rush a vehicle you cannot fill or afford to run well.
• Buying random brush tiers out of order because the icon looks cooler.
• Placing a Robot Dock with no belt path to Base Belt In.
• Dumping Shards into Class rerolls before the early path is done.
• Ignoring move speed entirely until every walk feels like a punishment hike.
• Assuming codes will bail out a bad shop plan—no codes are confirmed as of November 2026; see Codes.

Suggested spend milestones

• Milestone A: Dustpan Brush owned; short routes feel twice as productive.
• Milestone B: 6KG canister owned; you leave base for real tile clusters.
• Milestone C: Robot Dock placed and Dust Out belted into base; AFK-ish income begins.
• Milestone D: Choose bottleneck—personal tools, more automation, or Vehicles.
• Milestone E: Revisit Classes and money passes with Earn Cash Fast once the spine is stable.

Return to the Guides Hub whenever a patch (Ranger Drone, Flyable UFO, and later drops listed under Updates) adds machines that change priority. Until then, keep purchases boring and productive: brush, canister, dock, belts—then specialize.
