Observed Failure Patterns

Pattern 1: App Won’t Connect — Terms Pop-Up Loop

App opens, prompts to accept terms and conditions repeatedly, sometimes 3-4 times per session. Never establishes connection to vacuum.
Occurs every time app is opened, regardless of previous acceptance.
Usually indicates app data corruption or account sync failure. The app cannot store acceptance state.
Does NOT indicate vacuum hardware failure.

Pattern 2: Map Won’t Load / Won’t Render

App opens, vacuum shows online, but map screen is blank, gray, or stuck loading. Suction and other controls may be unresponsive.
Occurs after initial setup, firmware update, or when switching between vacuums.
Usually indicates cloud sync delay, map data corruption, or app version incompatibility.
Does NOT indicate vacuum navigation hardware failure.

Pattern 3: Vacuum Disconnects After Setup

Initial setup succeeds, vacuum appears in app, but within hours or days it shows offline and won’t reconnect without re-pairing.
Occurs after router reboot, power outage, or firmware update.
Usually indicates router band steering (5GHz interference), DHCP lease expiration, or weak 2.4GHz signal.
Does NOT indicate vacuum hardware failure.

Pattern 4: App Crashes When Opening

App launches, shows splash screen, then closes or freezes. May happen consistently or after specific actions.
Occurs after app update, OS update, or when loading large maps.
Usually indicates app memory leak, OS incompatibility, or corrupted cache.
Does NOT indicate vacuum hardware failure.

Pattern 5: Vacuum Visible in Router but Not in App

Router shows device connected with IP address. App shows offline or never discovers.
Occurs after network changes, VPN usage, or when phone switches cellular/WiFi.
Usually indicates app is on different network band, or mDNS/SSDP discovery blocked.
Does NOT indicate vacuum hardware failure.

Pattern 6: Setup Fails — Cannot Find Network

Vacuum enters pairing mode, app scans but never finds the device, or finds it but fails to complete setup.
Occurs during initial setup or after factory reset.
Usually indicates phone on 5GHz band, or phone and vacuum not on same temporary network during setup.
Does NOT indicate vacuum hardware failure.

Most Common Root Causes (Ranked by Field Frequency)

1. Phone on 5GHz During Setup — 35%

Why it happens: During initial setup, the vacuum broadcasts a temporary 2.4GHz network that the phone must connect to. If phone is connected to 5GHz home WiFi, the handshake fails.
Triggers: Dual-band routers with same SSID for both bands, phone auto-connects to 5GHz.
Confirms: Setup fails at “connecting to device” stage. Phone WiFi settings show connection to 5GHz band during setup.
Disproves: If setup completes but vacuum drops later, issue is different.

2. App Data Corruption / Cache Issues — 20%

Why it happens: Accumulated app cache or corrupted login tokens prevent proper connection or map loading.
Triggers: App updates, OS updates, multiple account logins.
Confirms: Terms pop up repeatedly. App crashes on launch. Clearing app cache resolves temporarily.
Disproves: If issue persists across multiple phones, problem is account or cloud.

3. Router Band Steering / 2.4GHz Weak Signal — 15%

Why it happens: Router pushes device to 5GHz band (which vacuum doesn’t support) or 2.4GHz signal is weak due to distance or interference.
Triggers: Router reboot, firmware update, vacuum moved to different location.
Confirms: Vacuum shows offline after hours/days. Router interface shows vacuum connected to 5GHz network.
Disproves: If vacuum stays connected for weeks, network is stable.

4. Firmware Update Failure — 10%

Why it happens: Incomplete firmware update leaves vacuum in partially updated state, breaking cloud communication.
Triggers: Power interruption during update, network drop during update.
Confirms: Vacuum worked before update, stopped immediately after. Factory reset does not restore connection.
Disproves: If vacuum connects after factory reset, update was not the issue.

5. Cloud Service Outage — 5%

Why it happens: Manufacturer cloud servers down, preventing app from authenticating or syncing maps.
Triggers: Server maintenance, regional outage.
Confirms: Multiple users report same issue. Vacuum connects to WiFi but app shows offline. Web dashboard also inaccessible.
Disproves: If app works on cellular data but not WiFi, issue is local network.

6. Vacuum WiFi Module Failure — 5%

Why it happens: Internal WiFi radio or antenna fails due to component degradation or physical damage.
Triggers: Age, power surges, water damage.
Confirms: Vacuum does not broadcast its own setup network. Factory reset does not produce pairing network. No SSID visible in WiFi scans.
Disproves: If vacuum broadcasts setup network, radio is functional.

How to Fix App Crashes When Opening Robot Vacuum App

Step 1: Clear App Cache (Android)

Go to Settings → Apps → [Robot Vacuum App] → Storage → Clear Cache.
Expected: App launches without crash. Terms pop-up may reset.
Failure: Still crashes.
Decision: If crash persists, offload app or reinstall.

Step 2: Offload or Reinstall (iOS)

Go to Settings → General → iPhone Storage → [App] → Offload App. Then reinstall from App Store.
Expected: App launches, map loads.
Failure: Still crashes.
Decision: If crash persists across multiple phones, issue is account or vacuum firmware.

Step 3: Log Out and Back In

In app, navigate to account settings. Log out completely. Force close app. Reopen and log in.
Expected: Terms accepted once, vacuum appears.
Failure: Terms loop continues.
Decision: If terms loop persists, account sync issue—may require account deletion/rebuild.

Why Won’t My Robot Vacuum Load Its Map After Setup?

Step 1: Verify Map Exists

In app, navigate to map section. Look for “Generate Map” or “Explore” option.
Expected: Map renders within 30 seconds.
Failure: Map blank or gray.
Decision: If no map, run a mapping run (not cleaning) to generate map.

Step 2: Run Mapping Run

Place vacuum on dock, fully charged. Start a dedicated mapping run (not cleaning). Let it complete without interruption.
Expected: Map appears after completion.
Failure: Map still blank after run.
Decision: If map doesn’t generate after 2 attempts, map data may be corrupted. Factory reset.

Step 3: Factory Reset and Remap

Perform factory reset (button combo until voice prompt). Delete app, reinstall. Set up as new device. Run new mapping run.
Expected: Map generates, room divisions appear.
Failure: Still no map after reset.
Decision: If factory reset fails to generate map, main board or sensor issue.

Shark / iRobot Wi-Fi Setup Fails

Common fix: Temporarily disable 5GHz band on router. Use 2.4GHz-only SSID for setup. Re-enable 5GHz after vacuum connects.
If persists: Vacuum may require firmware update via USB (check manufacturer support).

Rapid Triage Checklist (2-Minute Tests)

1. Phone Band Check During Setup

During setup, go to phone WiFi settings. Note which band phone is connected to (2.4GHz or 5GHz).
Result: Phone on 2.4GHz → proceed. Phone on 5GHz → disconnect from WiFi, let phone connect to vacuum’s temporary network during setup.

2. Router 2.4GHz Visibility Test

In phone WiFi settings, scan for networks. Look for the vacuum’s setup network (usually starts with “Robot” or brand name).
Result: Network visible → vacuum WiFi radio working. Not visible → vacuum may be in wrong mode or radio failed.

3. App Cache Clear Test

Force close app. Clear app cache (Android) or offload/reinstall (iOS). Reopen and attempt connection.
Result: Connects and map loads → cache issue. No change → deeper issue.

4. Cloud Status Check

Try accessing manufacturer’s cloud status page or downdetector. Note if others reporting outages.
Result: No outages reported → local issue. Widespread reports → cloud outage.

5. Factory Reset Observation

Perform factory reset (press and hold button combo until tones play, usually 10-20 seconds). Observe if vacuum broadcasts setup network.
Expected: Vacuum makes announcement, LED flashes, setup network appears in WiFi list.
Failure: No network appears, LED behavior unchanged. Indicates possible WiFi module failure.

Step-by-Step Diagnostic Procedure

Step 1: App Reset

Action: Clear app cache (Android) or offload app (iOS). Restart phone. Reinstall app if necessary. Log in.
Expected: App opens without repeated terms pop-up. Vacuum appears in device list.
Failure: Terms continue to loop, or vacuum not discovered.
Decision: If terms loop persists, account sync issue—skip to Step 3. If vacuum not discovered, go to Step 2.

Step 2: Setup Mode Verification

Action: Place vacuum within 10 feet of router. Press and hold dock button (or combo) until you hear “ready for setup” or LED flashes rapidly. Check phone WiFi for setup network.
Expected: Setup network appears in WiFi list within 60 seconds.
Failure: No network appears.
Decision: If no network, WiFi module may be dead. Escalate. If network appears, go to Step 3.

Step 3: Router 2.4GHz Configuration

Action: Access router admin interface. Temporarily disable 5GHz band. Ensure 2.4GHz SSID is visible and not hidden. Set channel to 1, 6, or 11.
Expected: Vacuum connects and stays connected after setup.
Failure: Still disconnects or fails setup.
Decision: If issue persists, go to Step 4.

Step 4: Network Exclusion Test

Action: Set up a mobile hotspot on a second phone with 2.4GHz only. Attempt to connect vacuum to hotspot.
Expected: Vacuum connects to hotspot and appears in app.
Failure: Does not connect even to hotspot.
Decision: If connects to hotspot but not home WiFi, router configuration issue. If fails to connect to hotspot, vacuum WiFi module suspect.

Step 5: Firmware Recovery Attempt

Action: Perform factory reset (button combo, listen for voice prompt). After reset, attempt fresh setup using manufacturer’s recommended procedure.
Expected: Setup completes, vacuum appears online.
Failure: Still fails after factory reset.
Decision: If factory reset fails to produce setup network or connection, WiFi module failure likely.

Physical Layer Inspection

WiFi Module Location: Open dust bin, inspect for visible damage, moisture, or corrosion near circuit board.
Antenna Trace: On main board, look for small antenna wire or PCB trace. Check for loose connection or cracked solder.
Reset Button: Ensure button clicks and is not stuck. Stuck button can prevent proper boot.
Water Damage: Look for white residue, green corrosion, or rust near charging contacts and main board.
LED Behavior: Observe status LED during boot. Normal: blinking, then solid. No LED or erratic blinking indicates power or board issue.

Electrical / Signal Verification

WiFi Signal Strength: During setup, use WiFi analyzer app. Vacuum’s setup network should show RSSI > -60 dBm at phone location.
Router 2.4GHz Signal: At vacuum’s dock location, measure router signal. RSSI should be > -67 dBm. Lower indicates weak signal.
Power Supply: Ensure dock provides stable voltage (typically 19V or 14-20V). Fluctuating power can cause radio instability.
Current Draw During Setup: Using USB power meter (if applicable), current draw should spike during WiFi connection attempt. No change indicates radio not powering.

Reset and Recovery Behavior Mapping

Normal Soft Reset: Press power button 10 seconds → LED flashes → unit restarts. Retains maps and WiFi credentials.
Factory Reset (Hard): Press and hold dock + spot buttons (or combo) 10-20 seconds → voice prompt “factory reset” → unit erases maps, WiFi, returns to setup mode.
Failed Reset (No Voice): Buttons pressed, no voice, LED unchanged. Indicates button failure or board issue.
Failed Reset (Network Missing): Factory reset completes (voice heard), but no setup network appears. WiFi module not initializing.

False Fixes That Do Not Work

“Reinstall the app repeatedly”: If issue is router band steering, reinstalling app won’t fix.
“Move router closer”: If vacuum connects but drops later, distance isn’t the primary issue—band steering or DHCP lease is.
“Use a WiFi extender”: Extenders often create double NAT and band confusion, making 2.4GHz separation harder.
“Disable firewall temporarily”: Firewall blocking cloud ports is rare; if setup fails at device discovery, firewall is not the issue.
“Just keep retrying”: Setup will not succeed if phone is on 5GHz. Retrying without changing band wastes time.
