Direct answer
For the iRobot Roomba 600 Series, confirm supported Wi-Fi band/security, account and pairing mode before deleting maps. First, place phone/robot near the router on the supported network.
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: will not connect to Wi-Fi or the app
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
The phone is on a 5GHz-only network the vacuum's radio can't join
What separates it The app finds no device during setup, or setup fails specifically at credential entry.
How to confirm Join the phone to the 2.4GHz network explicitly, since most vacuum Wi-Fi radios are 2.4GHz-only.
- 2
Guest network isolation or a VPN is blocking discovery
What separates it Setup appears to complete but the device never shows online, or previously worked and stopped after a router or network change.
How to confirm Disable guest isolation and any VPN for one setup attempt on the main home network.
- 3
The device is still claimed by a previous account
What separates it Setup finds the device but fails at the account-claim step, common on a second-hand unit.
How to confirm The previous owner needs to remove it from their account, or a support case with the serial number is the documented path to release it.
- 4
The device isn't in its documented pairing mode
What separates it The app never finds the device at all, even close by.
How to confirm Check the manual for the exact button press or reset sequence that puts this specific model into pairing mode.
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.
- Which network band the phone is joined to during setup.
- Whether this is a new setup or a previously working connection that stopped after a network or router change.
- Whether the device is new, second-hand, or being re-added after a factory reset.

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 will not connect to Wi-Fi or the app. 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.
- !Do not delete existing maps or weaken router security to work around a persistent connection failure until the actual cause is isolated.

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 "Cloud and Wi-Fi Connectivity Troubleshooting Guide". iRobot's own general/device-agnostic Wi-Fi and app connectivity 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 614, 675, 692, 694 is the scope applied here.

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.
The app can't find my robot vacuum during setup.+
Join your phone to the 2.4GHz network explicitly — most robot vacuum Wi-Fi radios can't see a 5GHz-only connection even if your router broadcasts both bands under the same name. Then confirm the robot is actually in its pairing mode using the exact sequence in the manual.
It was connected fine but stopped working after I got a new router.+
This is almost always a network-side setup issue, not a device fault — re-pair it on the new network, confirming the band and disabling guest isolation for that attempt.
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 Wi-Fi or app?+
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 Wi-Fi, app. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Do not delete maps or weaken security until the fault is isolated.
