The iRobot Roomba j9+ requires a 2.4GHz Wi-Fi network—it does not support 5GHz connections.

Network Specifications

| Requirement | Details | |-------------|---------| | Frequency | 2.4GHz only | | Security | WPA/WPA2 supported | | Internet | Required for smart features |

Dual-Band Router Notes

Most modern routers broadcast both 2.4GHz and 5GHz. The j9+ should automatically connect to 2.4GHz, but some routers handle this poorly.

Troubleshooting tips:

• Temporarily disable 5GHz during setup
• Create a separate 2.4GHz network name
• Ensure your phone is on 2.4GHz during pairing

Features by Connectivity

| Without Wi-Fi | With Wi-Fi | |---------------|------------| | Basic cleaning (Clean button) | App control | | | Scheduling | | | Room-specific cleaning | | | Smart mapping | | | Voice assistant integration | | | Software updates |

Signal Strength Recommendations

Position the Clean Base where Wi-Fi coverage is strong. Weak signal causes:

• Connection drops
• Failed data syncing
• Unreliable app control

If connectivity issues persist, move the base closer to your router or add a Wi-Fi extender.

The Bottom Line

The 2.4GHz requirement is standard for robot vacuums. As long as your network provides stable coverage where the Clean Base sits, connectivity should be reliable.
