Brain Test 5 level guide
Brain Test 5 Level 11 Walkthrough
Brain Test 5 Level 11 protects a vacuum robot from a cat and then guides that robot to clean a dusty room — but a blue water puddle blocks the path and must be cleared before the robot can finish the job.
Board Notes
- Layout
- Level 11 opens in a living room with a sofa, a large wooden cabinet with purple curtains, and a robotic vacuum cleaner on the floor. A black cat is approaching the robot from the right side of the room.
- Goal
- Part 1 requires blocking the cat before it damages the vacuum robot. Part 2 ("Vacuum all of the dust") tasks the robot with cleaning a room full of scattered dust particles, but a central blue water puddle cannot be vacuumed and must be removed first.
- Opening
- Part 1 — drag the large cabinet or furniture into the cat's path to block it from reaching the robot. Part 2 — drag the blue water puddle off the board to clear the robot's route, then guide the robot over all remaining dust particles.
- Danger Zone
- In Part 1, moving the vacuum robot away from the cat does not work — the cat will follow. The cat must be blocked with furniture. In Part 2, guiding the robot through the blue water puddle before clearing it stops the robot mid-clean.
- Mechanics
- Level 11 introduces the vacuum robot as a tool with a specific limitation — it cannot handle liquid. Part 2 is the first level requiring the player to clear an incompatible obstacle before using a tool.
Quick Tips for Brain Test 5 Level 11 (spoiler-free)
- In Part 1, use the furniture to block the cat rather than moving the robot — the robot cannot outrun the cat.
- In Part 2, clear the blue water puddle first by dragging or tipping it off screen before starting the vacuum path.
- Guide the robot in a broad sweeping path to ensure it covers all dust spots, including the corners.
How to Solve Brain Test 5 Level 11 — Full Solution
- Part 1 — "Protect the vacuum robot": drag the large cabinet or furniture into the path between the cat and the vacuum robot to block the cat.
- Part 2 — "Vacuum all of the dust": drag the blue water puddle off screen to clear the robot's route.
- Once the water is removed, guide the vacuum robot over all the scattered dust particles.
- Sweep the robot across every area of the floor until no dust remains.
- The room is clean and the level ends.
Common Mistakes to Avoid
- Moving the vacuum robot away from the cat in Part 1 — the cat follows and will eventually reach it. Block the cat with furniture instead.
- Sending the robot through the blue water puddle before clearing it — the robot stalls and cannot continue.
Frequently Asked Questions
How do I protect the vacuum robot in Brain Test 5 Level 11?
Drag the large cabinet or furniture between the cat and the vacuum robot to block the cat's path. Moving the robot itself does not solve Part 1 — the furniture is the barrier.
Why won't the vacuum robot clean everything in Brain Test 5 Level 11?
There is a blue water puddle in the center of the room that the robot cannot vacuum. Drag or flick the water puddle off screen first, then guide the robot through the full room.
