What does a home robot-vacuum repair shop actually look like?
A home shop is a clean desk, good light, a steady chair, labeled bins, and a workflow that moves from intake to test.
It looks like a simple electronics bench. Tools and parts sit in trays. The layout reduces dust and mistakes.
Space plan in one line
Create one straight line: intake → diagnosis → disassembly → cleaning → repair → reassembly → testing → packaging.
Key zones
Intake: A small table, tags, a camera or phone for photos.
Bench: An anti-static mat and wrist strap to control Electrostatic discharge (ESD).
Cleaning: A mini air blower, soft brushes, and 70–99% isopropyl alcohol.
Parts: Labeled drawers for belts, wheels, filters, screws, and connectors.
Test area: A test rug, a dark mat for cliff sensors, and a simple box maze.
Basic tools list
Spudger set and plastic picks.
Tweezers and side cutters.
Digital multimeter.
Soldering iron (temperature-controlled), lead-free solder, and flux.
Hot-glue gun, Kapton tape, cable ties.
Calipers and a small scale.
Label maker and zip bags.
How much does it cost to set up a home bench?
Start under $300. Upgrade over time as jobs pay for better tools and more parts.
A starter bench can be cheap. Most money goes to a few core tools and first-order parts.
Budget tiers
| Item | Starter (~$250–$350) | Growth (~$600–$900) | Pro Home (~$1,200–$1,800) |

Note: Prices vary by brand and region. Use this as a planning guide, not a fixed quote.
Where to save and where to spend？
Save on trays, bins, labels.
Spend on the soldering station and multimeter.
Buy mid-range hand tools once. They last.
Stock parts that solve the top five failures first.
What are the most common failures and quick wins?
Most issues are simple: clogged ducts, worn brushes, jammed wheels, tired batteries, or dusty sensors.
Cleaning and minor parts swaps fix most units. Start here before any complex repair.
The simple-first method
Clean filters, ducts, fan inlets, brush housings.
Inspect wheels, side brush gears, and belts.
Check the battery health and charge cycle.
Wipe and test cliff, wall, and bumper sensors.
Reboot and update the app or firmware if safe.
Common fault map
| Symptom | Likely Cause | First Fix | Parts to Keep |
Weak suction | Clogged ducts or dirty fan | Deep clean, replace filter | Filters, fan gaskets |
Spins in place | Wheel encoder dirty | Clean encoder window | Wheel modules |
Stops near stairs | Cliff sensors dusty | Clean with alcohol swab | Sensor windows |
Short runtime | Aged pack or charger issue | Test pack voltage and cycle | Battery packs, chargers |
Loud grinding | Brush gearbox debris | Open, clean, re-grease | Gears, Dielectric grease |
“Bin missing” alerts | Bin switch dirty | Clean switch and contacts | Micro-switches |
“Fan stuck” errors | Hair in impeller | Disassemble and clean | Replacement fans |
Won’t dock | Dirty charging contacts | Clean and test dock | Dock springs, pads |
How do you choose the right bench layout?
Use a straight flow. Reduce backtracking. Keep dirty work away from clean work.
A clean flow cuts time and errors. It also looks professional if customers visit.
A simple flow that works
Left to right if right-handed. Intake on the left. Testing on the far right.
Put cleaning tools near a small trash can.
Keep solder and heat away from plastic bins.
Hang a task light with a swivel arm over the center.
Bench height and comfort
Desk height at 72–76 cm for seated work.
Chair with lumbar support.
Anti-fatigue floor mat if standing.
Good light: 1,000+ lumens task lamp.
What safety steps matter at home?
Protect hands, lungs, eyes, and devices. Keep fire tools away from solvents.
Simple habits prevent damage to people and boards.
Essentials
Use an ESD strap on live boards to avoid ESD damage.
Wear eye protection when prying or cutting.
Ventilate when using alcohol or adhesives.
Unplug before opening housings.
Keep a small ABC fire extinguisher close.
Battery care
Treat lithium packs with care. Learn about battery management systems (BMS).
Never puncture or crush a cell.
Store packs at 40–60% state of charge in a cool, dry area.
Use a Li-ion safe bag for questionable packs.
What spare parts should you stock first?
Stock parts that solve 80% of cases. Keep small, cheap items in bulk. Order rare boards on demand.
Begin with consumables and common wear items.
Priority list
Side brushes and main brush belts.
Wheel modules with encoders.
Dust bin latches and seals.
Charging contacts and springs.
Bumper and cliff sensor windows.
Common fans and impellers.
Dock power supplies.
Packaging
Keep each part in a labeled zip bag.

Record supplier and batch.
How do you diagnose a robot vacuum without guesswork?
Use a repeatable flow. Measure. Test one change at a time. Keep notes.
A checklist and a few tools prevent rework and frustration.
A simple diagnostic flow
Intake: Record model, serial, fault description. Photograph the unit.
Power check: Does it charge and power on? Measure resting and load voltage with a Multimeter.
Self-test: Run any built-in tests in the app.
Mechanical: Spin wheels by hand. Listen for noise. Check brush play and belt tension.
Air path: Inspect bin seals, ducts, and fan.
Sensors: Wipe windows, test bumper action, dark-mat cliff test.
Firmware: Check app updates. Only update after backup and customer consent.
Isolated tests: Disconnect subsystems to see if faults clear.
Useful measures
Voltage: Pack nominal, charger output, and under-load dips.
Resistance: Motor coils (ohms) for open or short. Learn what an Ohm is.
Current draw: Inline meter when fans or wheels stall.
Temperature: IR thermometer for hot chips or cells.
What about firmware, apps, and connectivity?
Treat software as part of the device. Many “hardware” problems are app or Wi-Fi issues.
Start with resets and clean network steps. Update only with care.
Safe steps
Reboot the robot and the app.
Forget and re-add Wi-Fi on 2.4 GHz if supported.
Clear app cache.
Check regions and language.
Update only if stable power and good signal are available.
Do not bypass security or encryption. Respect terms and warranties.
When updates help
Map corruption.
Dock communication glitches.

Battery gauge mismatches.
How do you fix wheels, brushes, and gearboxes?
Hair and dust wear plastic parts. Clean first. Replace if gaps or cracks show.
Most drive issues come from encoders and debris.
Steps for wheel modules
Remove the module. Photograph orientation.
Open the case. Clean hair from axles and gears.
Check the encoder disk and sensor window. Wipe with alcohol.
Grease gear teeth lightly with dielectric grease.
Reassemble and test free spin.
Brush housings
Main brush: check end caps and bearings.
Side brush: check motor shaft play.
Replace belts that slip or crack.
Look for warped brush bars.
How do you restore suction power?
Airflow depends on seals, ducts, fans, and filters. One weak link cuts performance.
Clean the path. Replace the filter. Check the fan.
Steps
Remove bin and filter. Beat dust out outdoors.
Inspect ducts for clogs. Use a narrow brush or compressed air.
Open the fan housing if error codes point there.
Clean the impeller. Replace warped fans.
Replace worn gaskets and bin seals to stop leaks.
Signs of airflow problems
Louder than normal, but weak pickup.
Error codes for fan stall.
Fine dust escaping around the bin.
What should you know about batteries and charging?
Battery age limits runtime. Chargers fail too. Test both before ordering new parts.
