Qrevo Curv does not need a map or system reset just because app connectivity fails. Roborock documents a dedicated Wi-Fi reset, and its current Qrevo Curv support page says the robot connects on 2.4 GHz rather than 5 GHz. Prove that a usable 2.4 GHz network exists, reset only the robot's Wi-Fi, pair near strong coverage, and only then work on router band settings. A successful Wi-Fi reset followed by repeated failure on one router points away from the map and toward network configuration.
Confirm the exact model and exact code, light pattern or symptom.
Run the lowest-risk physical or software check first.
Use each pass condition to decide what the result actually narrows down.
Does this match your problem?
- The Roborock app cannot add or reconnect the Qrevo Curv even though the robot powers on normally.
- The robot still cleans from its buttons but app status is offline or setup repeatedly times out.
- The home router uses 5 GHz only, separate 2.4/5 GHz names, or one combined dual-band SSID.
Most likely causes
The robot's Wi-Fi state needs the dedicated model reset before pairing again.
No usable 2.4 GHz network is available even though a 5 GHz network is visible.
The phone and robot are pairing at the edge of Wi-Fi coverage or through an unstable band-steering setup.
The Roborock app or router configuration is blocking completion after the robot enters pairing mode.
What your test result means
| What you observe | What it narrows down | Next move |
|---|---|---|
| Robot never reaches the slow-blue Wi-Fi waiting state | Pairing has not reached the documented network-ready state. | Repeat only the dedicated Wi-Fi reset sequence and listen for the reset announcement before changing router settings. |
| Slow-blue state appears but a 5 GHz-only network is the only option | The robot is ready, but the network does not match Roborock's 2.4 GHz requirement. | Enable a usable 2.4 GHz path; do not system-reset the robot to solve a band mismatch. |
| Combined dual-band SSID pairs successfully | Band steering is not blocking this setup under the current conditions. | Leave the router unchanged and verify the robot stays online through a short task. |
| Combined SSID fails but a dedicated 2.4 GHz SSID works | Router band presentation/steering is the useful discriminator. | Keep the proven 2.4 GHz path or get router/ISP help rather than deleting maps. |
| Known 2.4 GHz network still fails after a clean Wi-Fi reset at strong signal | The controlled test has excluded the common band and weak-signal branches. | Escalate with router model, SSID structure and the exact pairing stage that fails. |
Reset can erase maps/settings on this path. Use lower-risk checks first and document the current state before resetting.
Run these checks in order
Confirm that 2.4 GHz actually exists
Before resetting anything, inspect the router's available networks. Roborock's Qrevo Curv support material says its robots currently use the 2.4 GHz Wi-Fi band and do not connect directly to a 5 GHz-only network. If the router broadcasts separate names, identify the 2.4 GHz SSID. If only a 5 GHz name appears, enable 2.4 GHz in the router or get help from the router/ISP provider before repeating robot setup.
Use the dedicated Qrevo Curv Wi-Fi reset
Use the model’s dedicated Wi-Fi reset rather than a factory reset. The current manual says the reset is complete when the power indicator flashes blue slowly and the robot waits for a connection. It also says Wi-Fi is automatically disabled if the robot waits more than five minutes, so reset Wi-Fi again before another pairing attempt after a long pause. This preserves maps and schedules while putting only the network path back into pairing mode.
Pair the phone and robot in strong coverage
Keep the phone and robot close enough to the access point that weak signal is not another variable. Open the current Roborock app, select the intended 2.4 GHz-capable network, and complete one clean pairing attempt. Do not move the dock, reboot several devices at once, or change multiple router settings during the same test because that makes the result hard to interpret.
Handle dual-band SSIDs deliberately
If the router has separate 2.4 and 5 GHz names, choose the 2.4 GHz network. If it uses one combined SSID, Roborock says to try that network first; if pairing still fails, the next useful action is to separate or enable the bands with help from the router manufacturer or ISP. This is more targeted than deleting maps or factory-resetting the robot.
Verify the connection survives one normal cycle
After the robot appears online, leave it connected long enough to confirm that app status remains available through a short cleaning/return-to-dock cycle. A robot that pairs once and then repeatedly disappears on a strong 2.4 GHz network has a different problem from a robot that never enters pairing state, so record the exact stage that fails before contacting support.
Contact Roborock when the Qrevo Curv reaches the documented slow-blue Wi-Fi pairing state, a usable 2.4 GHz network is confirmed, and setup still fails repeatedly. Include router model, whether the SSIDs are separate or combined, and the exact stage where setup stops. Avoid a full system reset unless you intentionally accept resetting broader settings and Roborock support recommends it.
What to collect before contacting support
Give support a reproducible case instead of “it doesn’t work.” That reduces repeated basic troubleshooting and preserves the clues from your tests.
- Exact model name and the error code / voice prompt exactly as shown
- A photo or screenshot of the app error and the time it occurred
- A short list of the checks already completed and what happened after each one
- Firmware/app version if the issue began after a software change
Manufacturer evidence
Roborock — Qrevo Curv Series User Manual (2026)
The current Qrevo Curv Series manual documents the dedicated Wi-Fi reset, a slow blue-flashing waiting state, 2.4 GHz-only support and automatic Wi-Fi disable after more than five minutes waiting for a connection. Roborock’s current Curv FAQ also explains dual-band router handling. For a combined dual-band SSID, Roborock says to try the shared network first and expose/separate 2.4 GHz if pairing repeatedly fails.

FAQ
Does Qrevo Curv support 5 GHz Wi-Fi?
No. Roborock’s current Qrevo Curv manual says only 2.4 GHz Wi-Fi is supported. If your router exposes separate 2.4 and 5 GHz network names, choose the 2.4 GHz SSID during setup. With a combined dual-band SSID, try it normally first; if pairing repeatedly fails, use the router or ISP controls to make the 2.4 GHz network explicitly available.
Do I need to factory-reset Qrevo Curv for Wi-Fi problems?
No. The manual provides a dedicated Wi-Fi reset specifically for connection problems, so a factory reset is unnecessary as a first step. Use the model’s button combination until the robot announces the Wi-Fi reset and the indicator flashes blue slowly, then add it again in the Roborock app. This keeps the troubleshooting scope on networking instead of wiping unrelated settings.
Why did the Qrevo Curv Wi-Fi pairing light stop waiting?
The current manual says Wi-Fi is automatically disabled if the robot waits more than five minutes for a connection. If setup was interrupted or the app sat too long, perform the dedicated Wi-Fi reset again and restart pairing promptly. That timeout can look like a second network failure even when the router settings did not change, so record the pairing stage before changing the router.
What should I do with a dual-band router during Qrevo Curv setup?
Roborock says its robots currently use 2.4 GHz Wi-Fi. If your router has separate SSIDs, select the 2.4 GHz one. If both bands share one SSID, try the combined network first; when pairing fails repeatedly, use the router or ISP settings to expose or separate 2.4 GHz. Avoid changing encryption, DNS and band settings simultaneously because that makes the failed condition harder to isolate.
How do I know whether the Qrevo Curv Wi-Fi fix is stable?
Do not stop at “device added.” After pairing, confirm the app can see the robot after it leaves and returns to the dock and after the phone reconnects to normal home Wi-Fi. A stable result survives that ordinary cycle without another Wi-Fi reset. If it drops offline again, record whether local cleaning still works and whether the app loses only cloud/network control before contacting Roborock.
