Direct answer
For the iRobot Braava jet m6 mop, outlet, charger, dock contacts, battery temperature and pack condition should be proved before replacement. First, cool to room temperature and use the specified charger/outlet.
What this covers
- iRobot Braava jet m6 mop (m6)
- iRobot Braava jet m6 — a mopping robot with no vacuum motor, no brush roll and no filter; it sprays and mops only.
- The specific fault this record addresses: will not charge
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
Dock or plug contacts are dirty or not making a clean connection
What separates it Charging is intermittent, or works when the unit is pressed firmly into the dock but not when simply set down.
How to confirm Inspect and clean the contacts on both the unit and the dock/charger with the power disconnected, and confirm dry contact with firm, flush seating.
- 2
The charger or cable itself has failed rather than the vacuum
What separates it No charging indication at all, regardless of contact cleanliness or seating.
How to confirm Swap in the specified charger/cable if a spare is available, or test the vacuum's charge port with a different known-good charger of the exact specified type.
- 3
The battery pack itself has failed
What separates it Confirmed correct temperature, clean contacts and a known-good charger, and still no charge indication or progress.
How to confirm This is the conclusion only once the accessory and connection points are ruled out.
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.
- Whether the unit was hot from recent use or cold from storage right before the failed charge attempt.
- Whether charging is fully absent or just intermittent depending on how firmly the unit is seated.
- Whether a specified replacement charger/cable is available to swap in as a test.
Let the unit reach room temperature before attempting to charge
ReversibleBoth very hot and very cold batteries can refuse to charge as a safety measure.
Inspect and clean dry contacts on both the unit and dock or plug
ReversibleConfirm firm, flush seating rather than a loose or angled connection.
Test with a specified replacement charger if available
ReversibleIsolates a failed charger/cable from a failed battery or charge port.
Confirm charge indication and useful runtime after correction
ReversibleA charge light alone isn't sufficient — confirm it actually holds a useful charge.
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
- m6. iRobot Braava jet m6 — a mopping robot with no vacuum motor, no brush roll and no filter; it sprays and mops only.
- Type — robot MOP only (no vacuum, no suction)
- The Braava jet m6 is a robot MOP, NOT a vacuum — it has NO suction and NO vacuum brushroll, so suction, brushroll and dust-bin symptoms do not apply to it. It sprays and mops hard floors with a pad, and it does not pick up loose debris (vacuum first). It maps and mops room by room.
- Mopping — pads & jet
- It uses a precision water jet and a wet or dry pad (single-use or washable). 'Not cleaning/streaking' is an empty water tank, a dirty/wrong pad, or using the wrong mode (wet vs dry pad). Use only water or the iRobot-approved solution — never other floor cleaners, which foam and damage it.
- Docking & navigation
- Charges at its dock and navigates by mapping; 'won't dock/charge' is dirty contacts or a moved dock, and getting stuck is usually wheels or a threshold it cannot cross. It works with Roomba for a vacuum-then-mop routine (Imprint Link).
- Symptom boundary
- This record covers iRobot Braava jet m6 mop when it will not charge. 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 swelling, heat, an odor, liquid exposure or visibly damaged contacts — do not continue attempting to charge a battery showing any of these.

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 "Why does my Roomba® or Braava® not turn on or charge properly?". iRobot's own device-agnostic ("Roomba or Braava", all series) not-charging article. Verified reachable and content-matched via the Browser tool 2026-08-28 after direct fetch was refused. What that article does not carry is the model boundary — it is written for a product line, and m6 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
My Braava jet m6 isn't picking up dirt / has no suction.+
The Braava m6 is a mop, not a vacuum — it has no suction and does not pick up loose debris at all. It is designed to mop hard floors after you (or a Roomba) have vacuumed, so it will smear dry debris around rather than remove it. Vacuum first, then let the Braava mop. If it is mopping poorly, check the water tank is filled, the correct wet/dry pad is fitted, and you are using only water or the approved solution.
My vacuum won't charge right after I finished using it.+
Let it cool to room temperature first — a battery that's still warm from use is often outside the charging circuit's allowed temperature range, which is a safety feature, not a fault, and resolves once it cools.
Does this answer apply to every iRobot model?+
No. It is scoped to m6. iRobot Braava jet m6 — a mopping robot with no vacuum motor, no brush roll and no filter; it sprays and mops only.
What should I record before troubleshooting not charging or battery?+
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 not charging, battery. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Stop for swelling, heat, odor, liquid or damaged contacts.
