Direct answer
For the iRobot Roomba 600 Series, the exact indicator pattern and operating stage are required before reset or parts replacement. First, record the light color, blink count or message.
What this covers
- iRobot Roomba 600 Series (614, 675, 692, 694)
- iRobot Roomba; mapping, obstacle avoidance, self-emptying and mop functions vary.
- The specific fault this record addresses: shows an error light, symbol or message
What it does not cover
- ×The same symptom on a different iRobot product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
A blockage or obstruction is present somewhere in the airway
What separates it The indicator appears alongside noticeably reduced suction or a stalling brush roll.
How to confirm Clear the airway as described under no-suction and brush-not-spinning before assuming a hardware fault.
- 2
A filter needs cleaning or has been left out entirely
What separates it The indicator appears specifically after a recent filter cleaning, or persists until the filter is confirmed reinstalled.
How to confirm Confirm the filter is present, clean, fully dry and correctly seated.
- 3
A genuine internal fault the indicator is specifically naming
What separates it The indicator persists after all obstruction, filter and battery conditions are confirmed normal.
How to confirm Look up the exact light color, blink pattern or symbol for the specific model in its manual — this is the only reliable way to interpret it, since patterns are not standardized across brands or even within a brand's own lineup.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- The exact light color, blink count or on-screen symbol, and the operating stage it appeared at.
- The precise model — indicator meanings are not standardized even across generations from the same manufacturer.
- Whether suction, brush operation or charging were also abnormal at the same time.
Record the exact indicator pattern and when it appeared
ReversiblePrecision here is what makes the manual lookup useful.
Check the manual for that exact model and indicator state
ReversibleDo not assume a pattern seen on a different model or a different brand applies here.
Complete only the specific action the manual documents for that state
ReversibleObstruction clearing, filter service, battery temperature or charge level, as applicable.
Confirm the indicator clears through a normal full run
ReversibleA one-time clear isn't sufficient if the underlying cause wasn't actually the one addressed.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- 614, 675, 692, 694. iRobot Roomba; mapping, obstacle avoidance, self-emptying and mop functions vary.
- Type — entry ROBOT vacuum (no mapping, no self-empty)
- An entry ROBOT vacuum that navigates by bump-and-go rather than mapping, and empties its own onboard bin (NO Clean Base self-empty on the 600 series). So it cleans in a semi-random pattern by design, and there is no map or self-empty base to troubleshoot — those symptoms do not apply.
- Docking & charging
- It finds its Home Base to charge; 'won't dock/charge' is usually dirty charging contacts, a moved/unplugged dock, or blocked clearance. Empty the onboard bin regularly since there is no self-empty base.
- Brushes, wheels & sensors
- A bristle brushroll plus a beater brush (older design that needs hair cleared more often), a side brush, wheels and cliff sensors — clear hair and wipe sensors if it gets stuck or picks up poorly.
- Symptom boundary
- This record covers iRobot Roomba 600 Series when it shows an error light, symbol or message. A different symptom on the same hardware, or this symptom on a different iRobot product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Stop for a red heat warning, smoke, swelling, or any indication paired with a burning smell or visible liquid damage.

Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. iRobot Support publishes this as "Roomba support". Official Roomba setup, error, mapping, cleaning and repair support. What that article does not carry is the model boundary — it is written for a product line, and 614, 675, 692, 694 is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
Why does my Roomba 600 clean so randomly and miss spots?+
The 600 series navigates by bumping into things and turning (bump-and-go), not by mapping the room, so it deliberately cleans in a semi-random pattern and relies on time and coverage rather than a planned route — it is not lost or faulty. Give it enough time per room, clean its dual brushes and side brush of hair (the 600's brush design tangles more than newer models), empty the bin often (no self-empty base), and it will cover the floor. For mapped, room-by-room cleaning you would need an i-series or newer.
There's a blinking light and I don't know what it means.+
The exact meaning is specific to the model and even the generation — look it up in that model's own manual rather than assuming a pattern from a different vacuum or brand. Record the color and blink count precisely before searching.
Does this answer apply to every iRobot model?+
No. It is scoped to 614, 675, 692, 694. iRobot Roomba; mapping, obstacle avoidance, self-emptying and mop functions vary.
What should I record before troubleshooting error light or blinking?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing error light, blinking. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Stop for red heat warnings, smoke, swelling or liquid damage.
