3. Virtual Walls for Roomba

  • The virtual walls keep Roomba in the area you want to clean and out of the areas you don’t.
  • To set up the dual-mode virtual wall, install two AA batteries
  • To select virtual mode, slide the switch to the up position.

  • The top ring will blink five times and then stop when the virtual mode is set up.
  • Virtual mode creates an invisible 10ft cone-shaped barrier that Roomba will not cross.
  • Be sure that the indicator on top of the virtual wall is pointing in the direction you want to get blocked.
  • Please note that next time, when the virtual wall blinks repeatedly, it means that the batteries are low and need to get replaced.
  • The halo mode on your dual-mode virtual wall keeps your Roomba away from items you want to protect creating an invisible 4ft diameter keep-out zone.
  • To select Halo mode, you need to slide down the button. The ring will pulse five times.

When the tower is set to emit a linear border near a drop-off, it can result in the best of both worlds: A Roomba that will vacuum over any dark surface while avoiding actual drop-off threats… Just remember to change the batteries in the virtual wall barrier every 6 months to ensure your Roomba does not decide to go cliff jumping!

4. Fix Roomba’s transition to carpet 

Generally, Roomba stops and reverses its position when there is a dark and a little height carpet. In this case, I have an Aluminium sheet installed below the carpet which has made the carpet a little higher. My Roomba stops when it tries to cross onto the carpet.


First of all, I popped out the wheel from Roomba and attached a tiny washer to it to make it a little higher. You can try a normal or small size washer depending on which would fit and doesn’t make it lose. Now, you should try your Roomba on carpet flour.

5. Move Roomba to a New Location

You can try this simple fix and fix your Roomba without doing any settings or troubleshooting with your Roomba. When your Roomba faces any cliff or unbalanced surface, it stops and turns its face back.
