I finally figured how to use the tags to get this question in the right place! I have used my robot vacuum several months now and it has performed well except for one possible flaw. When the vacuum is on carpet, in addition to the normal vacuum sounds, I hear the pulsing of a motor in the vacuum. Approximately one second on, one second off continuously while the vacuum is on my low carpet or even very low area rugs. I can only guess that it is the brush motor, possibly overloading and cycling. Does anyone else notice this? I emailed Wyze support with a video and sound. Their only response was that it was “normal.” I have checked the brush and cleaned it with no improvement. I should note that this sound only occurs on carpet.
