Frequently Asked Questions

Why does my Shark IQ keep disconnecting from WiFi?
Common causes include router interference, being out of range, or router settings like MAC filtering or dual-band issues. Ensure your vacuum is on a 2.4GHz network and within range.
Does Shark IQ support 5GHz WiFi?
No, Shark IQ robot vacuums only support 2.4GHz WiFi networks. Make sure your router is broadcasting a 2.4GHz signal and your phone is connected to it during setup.
How do I reset the WiFi on my Shark IQ vacuum?
Turn the vacuum off, then press and hold the 'Dock' and 'Power' buttons for 10 seconds until the lights flash. This clears the WiFi settings. Then set up the vacuum again in the SharkClean app.
Can I use a WiFi extender with my Shark IQ?
Yes, but the extender must broadcast a 2.4GHz signal. Some extenders use the same SSID as your main network, which can cause issues. For best results, use a dedicated 2.4GHz extender.
What does error code 15 mean on Shark robot vacuum?
Error code 15 indicates the vacuum has lost its WiFi connection. It is not a hardware failure, so you can usually fix it by reconnecting via the SharkClean app.
