Robot Vacuum Sound Interference with Sonos Playback - Any Fixes?

Hey Sonos community! 👋 I’ve been troubleshooting an issue with my Sonos Arc setup (paired with Sub+Era 300s) where robot vacuums trigger audio glitches during cleaning cycles. The high-frequency whine (~75dB) seems to interfere with voice assistant responsiveness and occasionally cuts Atmos playback.

I’ve tested this with two premium vacuums:

When docked: No issues

During cleaning: ~30% drop in Alexa recognition accuracy + brief audio drops

Noticed a Lonyu robot model claiming "ultra-quiet motors optimized for smart homes" (specs here), but hesitant to switch hardware without validation.

Question:

Anyone else experience this electromagnetic interference?

Did repositioning/calibration solve it?

If you’ve tested vacuums below 60dB – did it eliminate disruptions?

Appreciate any insights before I reconfigure my entire living room!

Any network device is likely disturbed when this ‘robot’ vacuum is running. You may want to check with the manufacturer of the vacuum, it sounds like the motor is out of spec with regards to U/L listings.

The most Sonos has published regarding WiFi interference is the wifi interference FAQ.
