## Product: iRobot Roomba j9+
**Brand:** iRobot

The [iRobot Roomba j9+](https://shopsavvy.com/products/HUSOWHflMsPLEUv9IqFo) 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.
