• iRobot Roomba i1 Repair Manual

• Roomba i1 Worn Battery

  Robot reports charging error 8, 9 or 10; battery won't charge or won't hold charge.

• Roomba i1 Battery Temp

  Robot reports charging error 6 (too hot) or 7 (too hot/cold) and pauses charging.

• Roomba i1 Drive Wheel

  Robot reports a drive fault; one wheel does not turn, robot spins or goes nowhere.

• Roomba i1 Battery Not Detected

  On the dock or charger the robot reports the battery isn't detected / connected and won't charge.

• Roomba i1 Clean Base

  On the i1+, the robot docks but the Clean Base never runs its loud evacuation, so the robot bin stays full; the app may report the bin is full or the base couldn't empty.

• Roomba i1 Wheel

  Robot beeps seven times / reports a wheel problem; may turn in place or refuse to move.

• Roomba i1 Bin

  Robot beeps once and reports the bin is missing, even when the bin appears to be in place.

• Roomba i1 Clean Base

  The app or the Clean Base indicates the dirt-disposal bag is full, or the base stops emptying and prompts you to change the bag.

• Roomba i1 Charge Circuit

  Robot reports charging error 2 or 3 and will not charge normally.

• Roomba i1 Clean Base

  The Clean Base runs but the robot bin still has debris afterward, the base is louder/weaker than usual, or fine dust blows around the dock.

• Roomba i1 Wi-Fi / App

  The iRobot Home app can't find or set up the robot, the robot drops off Wi-Fi, scheduled cleans don't run, or Alexa/Google voice commands stop working. The robot itself still cleans from the CLEAN button.

• Roomba i1 Noise

  Robot is noticeably louder than usual — grinding, rattling or buzzing.

• Error 10

  Robot reports a drive fault; one wheel does not turn, robot spins or goes nowhere.

• Charging Error 7

  Robot reports charging error 6 (too hot) or 7 (too hot/cold) and pauses charging.

• Error 5

  Robot beeps five times / reports a wheel fault and won't drive properly.

• Error 9

  Robot beeps nine times / reports a bumper fault; thinks it is permanently bumping something and won't drive forward.

• Charging Error 3

  Robot reports charging error 2 or 3 and will not charge normally.

• Charging Error 1

  On the dock or charger the robot reports the battery isn't detected / connected and won't charge.

• Error 2

  Robot stops, beeps twice / says to remove and clean the extractors. The Dual Multi-Surface rubber extractors may be stalled or struggling to turn.

• Charging Error 5

  Most common charging fault: robot reports charging error 5; charging is intermittent or won't start; base light may flicker.

• Error 6

  Robot beeps six times, reports a cliff/drop, backs up and refuses to continue — even on flat floor, or it won't cross a dark rug.

• Error 1

  Robot stops, sounds the two-tone error, beeps once, and asks to be moved to a new location. Often near edges, thresholds, or after the robot climbs onto something.

• Error 14

  Robot beeps once and reports the bin is missing, even when the bin appears to be in place.

• Charging Error 10

  Robot reports charging error 8, 9 or 10; battery won't charge or won't hold charge.

• FM-12: Roomba i1 Charging Error 6 / 7 — Battery temperature

  Symptom: Robot reports charging error 6 (too hot) or 7 (too hot/cold) and pauses charging. Likely root causes: Battery is above or below its safe charging temperature; Charging near a heat source (vent, radiator, sun); Robot just finished a long clean and the pack is warm; Very cold room / garage Next steps if owner-level checks fail: Error 6/7 appears at normal room temperature with no heat source — the battery's thermal sensor or the pack may be failing; replace the battery; if it persists, contact iRobot Customer Care 1-877-855-8593

• FM-02: Roomba i1 Error 2 — Clean the extractors

  Symptom: Robot stops, beeps twice / says to remove and clean the extractors. The Dual Multi-Surface rubber extractors may be stalled or struggling to turn. Likely root causes: Hair/string wound at the extractor ends or under the yellow bearing caps (still happens even on tangle-free rollers); Debris or a foreign object (sock, cord) jammed in the extractor bay; Worn or torn rubber treads, or a missing or damaged bearing cap; Extractor frame not latched after cleaning Next steps if owner-level checks fail: Extractors still stall after cleaning — replace the extractor set (~$25–$45); Extractor motor hums but rollers don't turn — gearbox/motor service; contact iRobot Customer Care 1-877-855-8593

• FM-11: Roomba i1 Charging Error 5 — Contacts / counterfeit battery

  Symptom: Most common charging fault: robot reports charging error 5; charging is intermittent or won't start; base light may flicker. Likely root causes: Dirty / oxidized charging contacts on the robot or the Home Base (most common); Counterfeit or incompatible battery; Robot not seated squarely on the base; Base not powered (its own light off) Next steps if owner-level checks fail: Error 5 continues with clean contacts, a powered base and a genuine battery — charge circuit may need service; contact iRobot Customer Care 1-877-855-8593

• FM-16: Roomba i1 Short runtime / dies before finishing

  Symptom: Robot used to run an hour-plus but now quits early, or returns to dock (or dies) after a short time. Likely root causes: Aging lithium-ion battery losing capacity (most common over time); Heavy carpet load drawing more power; Clogged High-Efficiency filter / debris on the extractors making the motor work harder; Battery never fully charging (dirty contacts — see FM-11); Counterfeit battery with overstated capacity Next steps if owner-level checks fail: Brand-new genuine battery still gives short runtime — charging circuit or motor draw issue; contact iRobot Customer Care 1-877-855-8593

• FM-18: Roomba i1 Loud noise / grinding / rattling

  Symptom: Robot is noticeably louder than usual — grinding, rattling or buzzing. Likely root causes: Hair/string wrapped in an extractor or wheel; Debris loose inside the bin or rattling in the body; Worn extractor bearing or end-cap; Object lodged in the vacuum path or fan; Worn drive-wheel module Next steps if owner-level checks fail: Grinding continues after clearing extractors, wheels and bin — a motor or drive bearing may be worn; contact iRobot Customer Care 1-877-855-8593

• FM-14: Roomba i1 Won't dock / Recharge & Resume not finishing

  Symptom: Robot fails to return to the dock, misses the contacts and doesn't charge, or during Recharge & Resume it docks but never goes back out to finish. Likely root causes: Dock in a poor spot (corner, under furniture, on carpet, too close to walls); IR docking beam blocked by furniture or strong sunlight; Charging contacts dirty (robot or dock); Dock unplugged / on a switched outlet; Battery too low or worn to navigate home / complete resume; Robot lost its place on the map (moved or picked up) so it can't resume Next steps if owner-level checks fail: Robot sees the dock but never seats on the contacts — check contact alignment/wear; if the IR receiver is suspect, contact iRobot Customer Care 1-877-855-8593

• FM-23: Roomba i1 i1+ Clean Base bag full / replace the bag

  Symptom: The app or the Clean Base indicates the dirt-disposal bag is full, or the base stops emptying and prompts you to change the bag. Likely root causes: The enclosed dirt-disposal bag is full (normal after ~30–60 days depending on use); Bag not fully seated, or the lid not closed, so the base reads it as missing/full; Non-genuine bag without the detection tab Next steps if owner-level checks fail: Base still reports “bag full” or “no bag” with a correctly seated genuine bag — the bag-detect sensor or lid switch may be faulty; contact iRobot Customer Care 1-877-855-8593

• FM-07: Roomba i1 Error 10 — Drive wheel not turning

  Symptom: Robot reports a drive fault; one wheel does not turn, robot spins or goes nowhere. Likely root causes: Drive wheel jammed by debris; Drive motor/gearbox fault; Wheel encoder failure; Wheel module worn out Next steps if owner-level checks fail: One wheel is dead or grinds under power after cleaning — replace the drive-wheel module (aftermarket modules available) or contact iRobot Customer Care 1-877-855-8593

• FM-15: Roomba i1 Weak suction / leaves debris behind

  Symptom: Robot runs normally but picks up poorly, leaves visible debris, or seems weak. Likely root causes: Bin full — the app reports bin status; High-Efficiency filter clogged; Extractors fouled with debris at the ends / under the caps; Side brush clogged, bent, or not spinning; Debris stuck in the bin intake / vacuum path Next steps if owner-level checks fail: Suction still weak after a full clean and fresh filter — vacuum motor/impeller may be failing; contact iRobot Customer Care 1-877-855-8593

• FM-13: Roomba i1 Charging Error 8 / 9 / 10 — Worn battery

  Symptom: Robot reports charging error 8, 9 or 10; battery won't charge or won't hold charge. Likely root causes: Battery worn out from age/cycles (error 9); Cell imbalance — pack can no longer balance/charge (error 10); General battery/charging fault (error 8); Counterfeit pack Next steps if owner-level checks fail: A new genuine battery still throws error 8/9/10 — robot charging circuit fault; contact iRobot Customer Care 1-877-855-8593

• FM-05: Roomba i1 Error 7 — Wheel problem

  Symptom: Robot beeps seven times / reports a wheel problem; may turn in place or refuse to move. Likely root causes: A drive wheel won't turn freely (debris or binding); Wheel motor/gear strained; Wheel dropped and lost traction repeatedly; Carpet too thick for the wheel to drive Next steps if owner-level checks fail: A wheel grinds, is silent, or won't drive under power — drive-module service; contact iRobot Customer Care 1-877-855-8593

• FM-20: Roomba i1 Wi-Fi / app won't connect; schedule or voice fails

  Symptom: The iRobot Home app can't find or set up the robot, the robot drops off Wi-Fi, scheduled cleans don't run, or Alexa/Google voice commands stop working. The robot itself still cleans from the CLEAN button. Likely root causes: Trying to join a 5 GHz network — the i1 only supports 2.4 GHz Wi-Fi; Weak Wi-Fi signal where the Home Base sits, or router too far; Wrong Wi-Fi password, or phone not on the same 2.4 GHz network during setup; Router settings (band steering, AP/client isolation, MAC filtering, captive portal); App or robot software glitch; account/cloud outage affecting voice; Robot needs a reboot or re-pair after a router/password change Next steps if owner-level checks fail: Robot connects but repeatedly drops off — signal/router issue; relocate base or add a 2.4 GHz extender; App still can't find the robot after re-pair on a confirmed 2.4 GHz network — contact iRobot Customer Care 1-877-855-8593
