Have you ever been startled by your robot vacuum suddenly turning on without warning? If so, you’re not alone. Many homeowners have experienced this issue and are left wondering why their robotic vacuums randomly turn themselves on. In this post, we’ll explore the potential causes of this common problem and provide helpful advice to get your robot vacuum running smoothly again. With a bit of detective work and some troubleshooting tips, you can identify what’s causing your robot vacuum to start unexpectedly and take steps towards solving the issue.

Why Does My Robot Vacuum Start By Itself?

Robot vacuums often only start by itself during a scheduled cleaning. However, some program malfunctions, time settings, remote or wifi connection issues can cause it to start by itself. It’s important to identify the cause and determine how to fix it.

Potential Causes of a Robot Vacuum Starting on its Own and How to Fix It

Sensor malfunctions

Sensor malfunctions can cause a robot vacuum to start on its own and can be difficult to identify the exact cause. Sensor malfunctions can occur when a dust particle obstructs the infrared sensor, which is responsible for detecting obstacles. This can cause the robot vacuum to think there are obstacles in its path, resulting in an unexpected startup. Additionally, dirt and debris can accumulate on the sensors, which can also cause them to malfunction. To fix the issue, you should clean the sensors with a soft cloth or cotton swab.

Programming errors

If your robot vacuum has been programmed to turn on at certain times of day, it may be starting up unexpectedly due to an error in its programming. To resolve this issue, you’ll need to access the robot vacuum’s programming settings and check for any errors or discrepancies. Additionally, if you have a timer-based scheduling system for your robot vacuum, it may be worth double-checking the times that it is set to run to ensure accuracy.

Battery problems

If your robot vacuum is running on low battery and its charging system is malfunctioning, it may start up unexpectedly in an attempt to return to its charging station. To fix this issue, you’ll need to check the robot vacuum’s battery level and replace or recharge if necessary. Additionally, if the charging system isn’t functioning properly, you should consult your manufacturer’s guide for troubleshooting advice.

Remote control interference

If your robot vacuum has a remote control, it may be due to interference from a remote control. This can happen when the device is too close to other infrared devices or electronic equipment and isn’t properly shielded. To prevent this issue from occurring, you should make sure that your robot vacuum is kept away from any remote controls or other devices and make sure it is properly shielded.

Corrupted memory

A corrupted memory can cause your robot vacuum to unexpectedly start up. To fix this issue, you’ll need to reset the robot vacuum’s memory by disconnecting the power source and then reconnecting it again after 5 minutes.

Pets or kids

This one is the most unlikely, but it’s not impossible. If your pets or kids are near the robot vacuum when it starts up unexpectedly, they may have pressed a button on its remote control and activated it unintentionally. To prevent this from happening again, you should make sure that any remote controls associated with your robot vacuum are kept out of reach of pets or children.

Wrong clock or time zone

If you just recently travel through different time zones with your robot vacuum, it may be the reason why it starting up unexpectedly. To fix this issue, you’ll need to access the settings of the robot vacuum and make sure that it is set to the correct clock and time zone.

Alexa or Google Home

If you have a connected robot vacuum to a group in Alexa or Google Home, it may be due to interference from your Alexa or Google Home devices. To fix this, remove your robot vacuum from the group.

Resumed cleaning

If your robot vacuum has a “resume cleaning” setting and it ran out of battery earlier, once it’s fully charged, it will resume the cleaning session and start by itself. To fix this issue, you’ll need to disable this feature or set the resume time to 0 so that the robot vacuum will not start up by itself.

Factory reset

Sometimes, a factory reset is required to fix any glitches. To do this, turn off the robot vacuum and unplug it from the power outlet. Then, press and hold the “power” button for around 10 seconds until you hear a beep. Once done, plug in the robot vacuum again and turn it on. This should reset the device to its factory settings and should resolve any unexpected starts.

If none of the above solutions work, then it may be worth contacting your manufacturer for further assistance. They will be able to provide more specific troubleshooting advice and can help you identify any issues with your robot vacuum’s hardware or software.


It can be quite annoying to have your robot vacuum start up by itself, but thankfully there are a few different solutions you can try if it happens. You should double-check any errors or discrepancies, and check the battery level as well as the settings of the device. Additionally, make sure that any remote controls associated with your robot vacuum are kept out of reach and that the clock and time zone are set correctly. If all else fails, have a factory reset or contact your manufacturer for further assistance.
