WiFiXpert Compatibility Score — iRobot Roomba
Same 2.4 GHz-only story as other robots, with a slightly friendlier setup process when it goes wrong.
Fussy — expect some setup pain
Eight checks, same for every device. The eight numbers below add up to 62.
The eight checks
| What we check | Rating | Points |
|---|---|---|
Works on 2.4 GHz Long-range band only. | Excellent | 14/14 |
Works on 5 GHz Setup fails if your phone is on a 5 GHz-only name. | Not supported | 5/14 |
Modern Wi-Fi security Works with current router security. | Good | 9/12 |
Happy on mesh Wi-Fi Slow to move between mesh boxes while cleaning. | Fair | 11/16 |
Works on a guest network Pairing needs phone and robot on the same network. | Poor | 3/8 |
Survives a plug-in extender Copes better than most, but splits can still break setup. | Usually fine | 5/8 |
Doesn't depend on chatty discovery Setup uses a temporary network from the robot. | Some dependency | 10/16 |
Easy to fix when it goes wrong The app walks you through re-pairing reasonably well. | Medium | 5/12 |
| WiFiXpert Compatibility Score | 62/100 | |
What usually goes wrong
Cleaning finishes but the map never uploads, or the robot shows offline on its dock.
Free things to try, in this order
- 1
Use one Wi-Fi name for both bands, or switch your phone to 2.4 GHz for setup.
- 2
Move the dock away from a metal shelf or a cupboard under the stairs.
- 3
Restart the robot from its dock before re-pairing.
Before you buy anything
Move the dock first. Mesh only if that corner of the house is weak for everything.
Answers about this gadget
What it needs from your network
2.4 GHz client that moves through the whole house while it works.
- Bands it uses
- 2.4 GHz only on most models. It will not see a Wi-Fi name that is 5 GHz only, and setup fails silently if your phone is on the 5 GHz half of a split network.
- How it's found
- Cloud for maps and control, local discovery during setup.
- Background discovery traffic
- Moderate during setup.
- On a guest network
- Setup fails.
- On a separate gadget network
- Fine on an IoT network.
Getting it set up
- • Set up with the dock near the router if you can, then move it.
- • Keep your phone on 2.4 GHz during setup.
- • Stand next to your router while you set it up, then move the gadget to where it lives.
- • Put your phone on the 2.4 GHz network name for the setup, or use one name for both bands so the phone can follow.
- • If your router splits bands into two names, turn the 5 GHz one off for five minutes rather than fighting it.
- • Turn mobile data off on your phone during setup — some apps quietly use it and never find the gadget.
With mesh Wi-Fi
- • Roaming between mesh boxes mid-clean can pause the map. Newer models cope; older ones don't.
