Be a Cleaning Robot Room Cleaning to 100%

Cleaning a room to 100% is the skill gate that separates casual roaming from real progression in Be a Cleaning Robot. Dust is not only in the open center of a floor—it hides along baseboards, behind furniture, on the far side of kitchen islands, and on stair edges. This guide shows how to push rooms and whole houses to completion, how to hunt the last particles, and how to plan dock routes so capacity never strands you across the map. Progress saves, so you can clear in sessions without losing percentage.

New players should skim Getting Started first. Movement issues belong on Controls. Spending choices that make 100% easier live on Upgrades.

Why 100% matters

Finishing a whole place—every room cleaned—unlocks the next house or venue on a ladder of about thirty locations. Stopping at 90% feels almost done, but the unlock does not fire. That last stubborn bathroom or balcony is the difference between staying in a small apartment and moving toward castles, cruise ships, space stations, and Galaxy Mall. See the Places Guide for the progression fantasy; this page is the micro technique that feeds it.

Cash also flows better when you are not randomly re-driving already clean tiles. Efficient 100% clears mean denser dust pickup per minute, fewer wasted loops, and better use of surprise mess events that re-dirty zones.

Be a Cleaning Robot room clearing gameplay

Read the room before you vacuum

When you enter a room:

1. Note the exits and which one points toward your nearest dock.
2. Spot large furniture blockers: beds, sofas, counters, display shelves.
3. Identify vertical complexity: lofts, stairs, sunken living rooms.
4. Estimate whether your current container can hold this room’s mess or whether you need a mid-room dump.

If the container is already half full from a hallway, empty first. Starting a large lounge on a half bin is how players get stuck across the house with no capacity.

Lawnmower lanes and edge passes

Use two passes per room:

Pass A �?Lawnmower lanes. Drive overlapping stripes across the open floor so you do not leave diagonal gaps. Keep slight overlap between lanes; dust engines often leave thin untreated ribbons when you guess spacing by eye.

Pass B �?Edge and object orbit. Hug baseboards, then orbit each large prop. Pause the camera on the far side of every sofa and island. Many “stuck at 99%�?cases are a single unvisited ring behind a bed frame.

On PC, strafe along walls with WASD. On mobile and console, creep the stick and tilt the camera down—see Controls for platform notes.

Finding the last dust

When the meter stalls near the top:

• Drop camera height and scan floor edges slowly.
• Check under tables and chairs by approaching from multiple angles.
• Revisit corners you cleaned while turning—turn radius often skips the apex of a corner.
• Inspect stair treads, landings, and the strip beside banisters.
• Look at thresholds between rooms; dirt loves door rails and rug edges.
• After a surprise mess event, re-check rooms you already marked done; events can reseed dust in “finished�?spaces.

Do not spam full-speed circles in the room center. Slow perimeter work finds the last percent faster than panic boosting.

Dock routes that protect your percentage push

Every serious clear needs a dock plan:

1. Memorize the shortest path from each major wing back to a dock.
2. Empty when the container is high—not only when it is jammed full mid-corner.
3. If a room is huge, schedule a dock trip at the natural halfway point (after Pass A, before Pass B).
4. In multi-floor homes, prefer docks that minimize stair climbs while carrying a full bin.
5. When playing with friends (each friend grants +10% cash, servers up to 10 players), call docks so you are not three bots clogging one pad during an event rush.

Container upgrades reduce how often this chore appears; speed upgrades reduce how long each trip costs. Suction helps you finish Pass A faster so you reach the dock decision sooner. Combo rewards clean streaks of efficient play—details in Upgrades.

Multi-room house strategy

Clear houses like a checklist, not a mood:

1. Pick a starting wing adjacent to a dock.
2. Finish each room to 100% before you deeply enter the next, unless a quest forces a detour.
3. After each room, glance at overall place progress so you know remaining holdouts.
4. Leave a final “verification lap�?around the whole place before you assume the unlock is ready.
5. Bank cash at the dock, buy any urgently needed container/speed levels, then step into the newly unlocked venue when it appears.

Because progress saves, you can stop after two 100% rooms and return tomorrow. That is better than rushing five rooms to 80% and forgetting where the gaps were.

Special mess patterns

Starter apartments: Small footprints teach edge discipline. Use them to practice camera hunting before castles punish you.

Large homes / castles: Long sightlines hide side chambers. Clear wing by wing and keep a mental map of unchecked closets.

Cruise ships: Corridors and repeated cabin layouts cause “did I clean this one?�?confusion. Mark a direction of travel (bow to stern) and do not skip identical-looking rooms.

Space stations: Verticality and modular rooms make dock memory critical. Empty more often until container upgrades catch up.

Galaxy Mall: Wide floors and prop density demand lawnmower discipline plus frequent camera checks around kiosks. Bring speed and container; suction alone will not save a bad route.

Events, quests, and 100% focus

Daily rewards and quests sometimes pull you toward earning cash or visiting a zone. Fold them into the clear: vacuum toward the quest objective along a lane you still needed, then dock. Surprise mess events are high-value—pivot, clear the seeded dust, empty, then resume the room checklist so you do not lose your place in the house plan.

Upgrades that make 100% easier

• Container: Fewer mid-room interruptions.
• Speed: Faster dock returns and faster perimeter laps.
• Suction: Quicker elimination of dense patches so Pass A ends sooner.
• Combo: Extra payoff when your route stays smooth.

Swap robots when a new bot’s baseline stats fit the venue better, but remember upgrades are per robot. A shiny Infinity with an empty upgrade sheet may lose to a geared starter in a messy mall. Compare options on the tier list after you can already finish rooms on technique alone.

Common reasons you cannot unlock the next place

• One room left at 97�?9% with hidden edge dust.
• A balcony, garage, or closet counted as its own room you never entered.
• An event reseeded a “finished�?room and your overall place flag dropped.
• You emptied cash but never finished the verification lap.

Walk the place with camera down, room by room, until every percentage reads complete.

Practice drill (ten minutes)

1. Enter the smallest dirty room available.
2. Complete Pass A and Pass B without docking if capacity allows.
3. If you are not at 100%, spend three minutes only on edges and orbits—no center driving.
4. Dock, then repeat in the next room.
5. After two rooms, note how many dock trips you needed; that number tells you whether container or speed should be your next purchase.
