However, no matter how popular or good a brand is, all vacuums can malfunction eventually.

A common issue is the Eufy RoboVac side brush not spinning. But why does that happen?

If your Eufy RoboVac side brush is not spinning, it may be due to the side brush module being jammed, a poorly-lubricated side brush motor, or lodged debris inside the gearbox or under the side brush.

In this guide, I will help you troubleshoot the issue and walk you through fixing it.

Eufy RoboVac Side Brush Not Spinning – An Easy Guide

A Eufy RoboVac side brush can stop spinning due to the following reasons:

  • The side brush needs cleaning
  • Dirty side brush motor
  • Poorly-lubricated side brush motor
  • Lodged debris under the side brush

This guide will help you troubleshoot the issue and hopefully fix it without the need to contact Eufy customer support.

However, make sure you contact Eufy if you feel stuck or if none of the steps has worked for you.

1. Clean The Eufy RoboVac Side Brush

  • Turn the Eufy RoboVac upsidedown
