Cleaning the house is difficult after a demanding day at the office. However, we are fortunate to have a shark robot vacuum at home. Considering that it can clean your home without you having to lift a finger and makes you forget about vacuuming manually. It is the reason why many people purchase this top-notch tool.

But anything automated will inevitably have issues, and the most prevalent of these is that the shark robot vacuum randomly starts or turns on by itself.  And you’re here precisely to know everything about this issue.

So pals, gear up! This article will discuss all potential reasons and solutions for this issue. So, stay with us, then.

Why Does My Shark Vacuum Turn On By Itself

Shark vacuums are unquestionably among the best tools for cleaning the house. Still, occasionally you may notice that your vacuum ignores the cleaning schedule you gave it and instead follows its schedule. It will occasionally start cleaning your house in the middle of the night to annoy you. Right, it may be frightful! You may be concerned that a ghost must operate your robot vacuum at night, but there is no reason to be afraid. 

You’ll be relieved to learn that there are many other understandable reasons why your shark robot vacuum randomly starts. We have all of them listed below. Let’s explore these.

10 Reasons Your Shark Robot Vacuum Randomly Starts

Let’s take a closer look at the following reasons, which will help you determine why your vacuum turns on and also we will provide you with solutions for each reason. Let’s get started:

  • Corrupted memory
  • Incorrect time zone
  • Re-Scheduled Cleaning Cycle
  • Accident Scheduling
  • Your Pets and kids 
  • Resuming Cleaning
  • Alexa
  • Dust
  • Charging contacts and sensors
  • Software Update

Corrupted Memory

corrupted memory

Let’s begin with the most typical issue. Your vacuum starts unexpectedly at strange times due to memory corruption. You can resolve this issue by taking out and reinserting your vacuum batteries. A planned clean-up may be mistaken for your vacuum by the damaged program. Any memory will be deleted after removing the batteries.

Incorrect Time Zone

Another justification for your vacuum troubleshooting is this. Your Shark robot vacuum will start at the wrong time if you schedule cleaning sessions without correctly configuring the time zone. For instance, your vacuum might still operate according to the previous time zone and start at unusual hours if you just traveled outside or returned home from another time zone.

Additionally, the times are set independently of your phone if you use a Wi-Fi-controlled shark robot. The scheduling times may vary if your app is in the incorrect time zone.

Please set it to your current time zone to solve this problem, and your Shark robot vacuum will begin its cleaning cycle at the proper time.

Re-Scheduled Cleaning Cycle

Your Shark vacuum may still be loyal to its previous owner. In other words, your robot vacuum is performing according to its previous plan. This issue arises when you purchase a returned vacuum that has already been used regularly.

Start a new cleaning cycle and cancel the one currently planned to resolve this. By doing this, your shark robot vacuum will begin cleaning your home whenever you like.

To achieve this, open the SharkClean Mobile App and navigate to the menu bar in the upper left corner of your smartphone’s screen (see screenshot if you need help finding it). Choose the schedule option, then program your shark robot vacuum cleaner to do what you want.

Accident Scheduling

It can result from an incorrectly set clock or faults when putting up an automatic cleaning plan. It’s also possible that you unintentionally created a schedule you’re unaware of. So be attentive and focused while setting a cleaning schedule for your vacuum. 


  • Helps in recognizing potential sources of accidental scheduling, aiding in preventing future occurrences.
  • Highlights the importance of attentiveness and focus during the scheduling process, reducing the likelihood of accidental setups.


  • Incorrectly set clocks can lead to unintended scheduling, disrupting the cleaning routine.
  • Malfunctions in automatic cleaning plans might trigger accidental scheduling, causing inconvenience.

Your Pets And Kids 

If your vacuum starts up at strange times, there is no need to assign blame to any ghosts. Since the cause might be those adorable little creatures living in your home, if your lovely pet decides it’s time to clean, nothing will stop it. Although it may seem silly, it might happen if your children or pets unintentionally hit the clean button on your shark vacuum.

Resuming Cleaning

When your vacuum starts cleaning unexpectedly, you may not need to worry because it does not necessarily indicate something is wrong. Sometimes it just ran out of power on the first run, which is why it did that. It had to charge up to continue where it had left off.

We see you are relying on Alexa to do your quick work. Right. There are chances that Your vacuum will start working when the lights are switched on in the room if you add it to an Alexa room group. As a result, if you ask Alexa to turn on the living room lights, your vacuum will turn on and begin cleaning. Therefore, we cannot blame your vacuum for this.


As you know, our smart shark robot effectively removes dust from your home. Still, after frequent use, dust may have accumulated at the buttons or beneath the cover near its buttons, which could cause your shark robot to malfunction and start at random. Cleaning the buttons and the area under the cover near the buttons will help you solve this issue.

Charging Contacts And Sensors

The reason for your shark robot’s irregular startup could potentially be a bad connection between the docking sensors and charging connectors when docked on base. Although it’s rare, sometimes it does happen.

To fix this problem, Clean the docking and charging contacts and the clean base thoroughly with a slightly wet magic eraser.

Software Update

If you’ve done everything and the issue persists, it may be time for a software update. Your robot may malfunction due to a software update error, and a random startup may contribute to the problem.

A method that will likely address any software-related problems with a malfunctioning device, including this issue with your Shark randomly turning on, is described below and probably resolves 99% of the problems with your shark robot vacuum.
