Do not force a Roomba Max 705 onto 2.4 GHz just because older Roomba advice says to. iRobot’s current Roomba Home App setup table lists the Max 705 Series as supporting both 2.4 GHz and 5 GHz. Start by keeping the robot charging on a powered dock near good Wi-Fi coverage, then verify Bluetooth, precise location and local-network access on the phone. The most useful branch is where setup stops: if the app never discovers the robot, work the phone-to-robot discovery path; if discovery succeeds but Wi-Fi provisioning fails, test the exact home network and, when practical, a phone hotspot. A successful hotspot setup points away from a dead robot radio and toward the home router, firewall, VPN, ad blocker or network configuration.

Does this match your problem?
- A Roomba Max 705 Combo or Max 705 Series robot is being added to the current Roomba Home App and setup will not complete.
- The app cannot discover the nearby robot even though the dock is powered and the robot is charging.
- Robot discovery works, but setup fails after you select or enter Wi-Fi credentials.
- You were told to disable 5 GHz and need to know whether that advice actually applies to Max 705.
Most likely causes
The robot is not on a powered charging dock or the dock is in a weak Wi-Fi area during initial setup.
Bluetooth, precise location or local-network permission is disabled on the setup phone, blocking nearby-device discovery.
The phone is not connected to the network you intend the robot to use, or the wrong SSID/credentials are being entered.
A router, firewall, VPN, ad blocker, client-isolation rule or mesh configuration is interfering after robot discovery.
The app cannot automatically find the robot and the temporary Roomba setup network has not yet been selected manually.
What your test result means
| What you observe | What it narrows down | Next move |
|---|---|---|
| The app never discovers the Max 705 nearby | Phone-to-robot discovery is failing before home Wi-Fi credentials are even the main issue. | Verify Bluetooth, Precise Location/local-network permissions, robot power and proximity; then retry Add a New Product. |
| The app finds the robot but rejects/loses the selected home network | Discovery works, so focus on SSID/password and router/network policy rather than robot Bluetooth. | Enter credentials manually, remove unsupported special characters if the app flags them, and keep the phone on the intended network. |
| Someone says the Max 705 must use 2.4 GHz only | That is legacy advice for older Roomba lines; iRobot’s current table lists Max 705 Series on both 2.4 and 5 GHz. | Use either supported band with good signal and troubleshoot the actual stage that fails instead of disabling 5 GHz by default. |
| Setup completes but 'Unable to Connect' appears immediately | Provisioning reached the account/network stage but subsequent service communication is blocked or stale. | Close/reopen the app, then use Product Settings > Wi-Fi Settings > Reconnect or Change Product Wi-Fi and verify required outbound traffic if managed network rules apply. |
| A simple phone hotspot works but the home network does not | The robot radio and basic provisioning path are functional; the home router/network configuration is now the stronger branch. | Check VPN/ad blocking, client isolation, DNS/firewall rules and mesh behavior; avoid factory reset until the network branch is resolved. |
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
Start with the Max 705 charging on a powered dock near the router
Remove shipping tape/films, place the dock on a level unobstructed surface and power it. iRobot recommends locating it where Wi-Fi coverage is strong during setup. Put the Max 705 on the dock and confirm it is charging before pairing. This prevents a discovery failure caused by an unpowered robot from being misread as a router problem. Keep the phone nearby and connected to the home network you actually intend the robot to use.
Enable the phone permissions used for nearby discovery
Turn on Bluetooth and allow the Roomba Home App the requested location/Precise Location and local-network access. iRobot uses Bluetooth where possible to discover nearby robots during setup. If the app cannot see the Max 705 at all, fix this phone-to-robot layer before changing SSIDs or router channels. Also make sure you are using a supported smartphone rather than a tablet-class device, which iRobot no longer supports for setup.
Use the current Max 705 dual-band rule
The manufacturer’s current setup table lists Roomba Max 705 Series as supporting both 2.4 GHz and 5 GHz. Do not force a 2.4-GHz-only network solely because older i/e/Essential advice says so. Select the network with reliable coverage at the dock and keep the phone on that same network during provisioning. If the app flags special characters in the SSID or password, simplify them for setup as iRobot recommends and type the password manually instead of pasting.
Separate discovery failure from Wi-Fi provisioning failure
Choose Add a New Product and let the app search for nearby robots. If the Max 705 appears, press Set Up and follow the Wi-Fi prompts; if it never appears, stay on the discovery branch rather than repeatedly re-entering router passwords. When asked, press the robot power button so the app can confirm it is pairing with the intended device. Stay on the setup screen until association completes, then give the account/cloud step a few minutes before judging the result.
Recover an immediate post-setup connection error without wiping the robot
If setup appears successful but the app immediately reports that Roomba cannot connect, first close and reopen the app. Then use Product Settings > Wi-Fi Settings > Reconnect or Change Product Wi-Fi and re-enter the network details. On managed home networks, iRobot publishes outbound port requirements including DNS, time, HTTPS and MQTT traffic. A VPN, ad blocker, client isolation rule or restrictive firewall can interfere even when the password itself is correct.
Use a simple hotspot only as a discriminator, then preserve the result
When practical, a phone hotspot with a simple SSID/password can tell you whether the Max 705 can complete basic network provisioning away from the home router. If the robot works there but repeatedly fails on the home network, focus on router/firewall/mesh configuration instead of declaring the robot radio dead. If the robot fails both a clean hotspot and the home network after discovery works, save the exact stage/error for iRobot. Do not factory reset merely because one network branch is misconfigured.
Contact iRobot when the Max 705 is powered and discoverable but cannot complete provisioning on a known-good network, or when it cannot be discovered despite correct phone permissions and a current app. Record the exact stage: not found nearby, password/network failure, or post-setup ‘Unable to Connect.’ If a simple hotspot works, include that result because it strongly narrows the problem toward home-network configuration. Avoid factory reset until you have separated those layers.
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
- Robot serial number and proof of purchase if warranty may apply
Manufacturer evidence
iRobot Roomba Home App setup — Max 705
Primary evidence is iRobot Knowledge 10503, the current Roomba Home App setup procedure. It explicitly lists Max 705 on both 2.4 and 5 GHz and documents Bluetooth/location permissions, dock placement, setup flow, special-character caveats and post-setup reconnect handling. The Max 700 software release notes are the companion source for first-run cloud provisioning and software/Wi-Fi fixes. Together they supersede older 2.4-GHz-only Roomba advice.

FAQ
Does the Roomba Max 705 support 5 GHz Wi-Fi?
Yes. iRobot’s current Roomba Home App setup table explicitly lists the Max 705 Series as supporting both 2.4 GHz and 5 GHz. That is important because many older Roomba models were 2.4-GHz-only. Do not disable 5 GHz by default. Use a supported band with good signal at the dock and troubleshoot the stage that actually fails: discovery, credential transfer or post-setup connectivity.
Why can the Roomba Home App not find my Max 705 during setup?
If the app never discovers the robot, focus on the phone-to-robot layer first. Confirm the Max 705 is powered and charging, then enable Bluetooth, Precise Location/location service and local-network access for the app. Keep the phone close to the robot and use the current Roomba Home App. Router-password troubleshooting is premature until nearby discovery works or the app advances to the home-network selection stage.
Should I disable 5 GHz before pairing a Roomba Max 705?
No, not as a blanket rule. The Max 705 supports both 2.4 and 5 GHz according to iRobot’s current setup table. Disabling 5 GHz can hide the real problem and is legacy advice for different models. Keep the phone on the network you want the robot to use, enter credentials manually if needed, and only change router settings when the failure is clearly at the home-network stage.
What does it mean if Max 705 works on a hotspot but not home Wi-Fi?
A successful simple-hotspot test is strong evidence that the robot can discover, authenticate and establish a network connection. The home router then becomes the stronger branch: check VPN/ad blocking, client isolation, mesh behavior, firewall/DNS rules and the SSID/password. Preserve the successful hotspot result. It is more diagnostic than repeatedly factory-resetting a robot whose radio has already proven it can connect elsewhere.
Why does a new Max 705 need the app before its first cleaning?
iRobot’s Max 700 release notes say robots shipping with factory software 7.2.3 or later must connect to the cloud before their first mission. Pressing CLEAN before provisioning can produce a setup prompt. After successful app/cloud setup, the robot may be disconnected from Wi-Fi and used offline. This requirement is therefore an initial provisioning dependency, not proof that every future cleaning mission permanently requires internet access.
