How do Roomba Virtual Walls Work?

Are you interested in learning more about the Roomba virtual wall? We often ask how the Roomba virtual wall works.

Because we have tested many Roombas and advised many people along the way. As it comes out, a few little black buildings suddenly improve a Roomba’s efficient and clean movement.

What is the essential operation of the Roomba virtual wall? To signal and stop a Roomba from visiting another extra space, virtual wall boundaries for Roombas produce an invisible, invisible signal that goes up to 10 feet.

It keeps it in the locations you specify by building an invisible wall that only a Roomba can perceive.

So were you aware that iRobot offers three different models of virtual walls? We’ll explain a Roomba virtual wall’s operation in this article.

To make it easier for everyone to understand the fantastic features of a Roomba, this manual was prepared with beginners in mind. The secret to improving your favorite Roomba is to understand them.

The Purpose of the Roomba Virtual Wall

Three main but different types of virtual walls are provided by iRobot. Every virtual wall performs by releasing an infrared signal that only a Roomba can recognize.

These control techniques, unfortunately, have changed over time and operate a little differently now. In more detail, each virtual Wall performs as follows:

1. Virtual Wall

iRobot’s first and only physical containment technique is called the Virtual Wall. It functions by producing an invisible infrared beam (up to 8 feet long) that a Roomba cannot pass.

This makes it simple to keep a Roomba limited in a specific room or region and prevent it from running into anything valuable or dangerous.

The virtual wall can be turned on automatically rather than manually. The battery is supposed to last around six months before it has to be replaced before it stops working.

Unfortunately, the Dirty Dog, Roomba 400 Series, Discovery Series, Original Series, and Create models can only use the Virtual Wall.

2. Light on a virtual wall

The Virtual Wall Lighthouse supersedes the Virtual Wall. It was first designed to work with the more antique Roomba 500 Series.

Unfortunately, the Lighthouse only works with a few Roomba 500 Series models, including the Roomba 780, 790, 877, and 880. The light has two operating modes:

Virtual Wall Mode: This method limits access to certain areas of your home. To stop a Roomba from walking into a room, you can place it at doors.

Lighthouse Mode: Keeps a Roomba in one room when it has finished cleaning it before allowing it to go on to the next.

Its most vital feature is the Lighthouse Mode’s ability to serve as a controlled lock. When a Roomba crosses the obstruction, the infrared beam will stop it.

3. Virtual Wall in Dual Mode

The Dual Mode Virtual Wall is the most recent and advanced sort of physical containment technology.

It allows you more control over where a Roomba cleans than the two prior virtual wall iterations. The Dual Mode Virtual Wall has two modes, like the Lighthouse, and they are as follows:

Virtual Wall Mode: This mode restricts access to some areas of your home. To stop a Roomba from entering a room, you can place it at entrances.

Lighthouse Mode: Provides a protective, 24-inch-diameter circular zone that a Roomba will not approach. It may be moved to shield objects.

The Halo Mode can safely shield things like dog bowls, plant vases, and small furniture.

How Do You Use the Virtual Wall for the Roomba?

The iRobot Virtual Wall is straightforward to set up. We will limit our focus to explaining how to operate the iRobot Dual Mode Virtual Wall because it is the only virtual Wall compatible with every Roomba model. Thankfully, it’s simple to locate the virtual Wall. This is how to apply it:

1. Use of the Virtual Wall Mode.

Install the two AA batteries to activate the Virtual Wall Mode. The switch should then be moved to the UP position.

After five pulses, the top ring will stop when the Virtual Wall Mode is activated. Even if the light stops pulsing, the virtual Wall remains operational. Make sure the indication is pointed in the desired blocking direction on top.

2. Utilizing Halo Mode.

Slide the switch to the DOWN position to activate Halo Mode. After five pulses, the top ring will cease when the Halo Mode is activated.

The Halo Mode remains active while the light stops flashing. Place the virtual Wall in the center of any things you wish a Roomba to avoid once it has been set up.

Has the Roomba 870 Wi-Fi?

The Roomba 870 offers high performance and quality and comes with Aero Force cleaning and lifetime home mapping.

It improves over earlier Roomba models significantly thanks to these two characteristics. You can operate the Roomba 870 without Wi-Fi or an app because those features weren’t available when it first came out.

How do Lighthouse and virtual walls differ from one another?

The Lighthouse provides a barrier between the room that should be finished first and the room that should be finished second. The virtual Wall prevents the Roomba from going into areas that are off-limits.

Does the Roomba i3 have a virtual wall?

iRobot Roomba Dual Mode Virtual Wall Barrier is included in the package.

Does Roomba i7 require a virtual Wall?

The Roomba i7 and s9 are the only Roomba models that feature Keep Out Zones in the app. The Dual Mode Virtual Wall(s), which may be purchased as an extra attachment if needed, would still be used by the 900 series.

How frequently should the Roomba i3 be cleaned?

Every morning, empty the trash and give them a thorough cleaning every 2-3 months.

Does the Roomba 692 have a virtual wall?

Intelligent sensors drive the robot about your home, moving under and behind furniture to assist in cleaning your floors properly.

You have more control over the areas your robot cleans thanks to the additional Dual-Mode Virtual Wall Barriers. To control cleaning, use Google Assistant or Amazon Alexa voice commands.

Do virtual walls work with the Roomba i3?

Roomba Dual Mode by iRobot Halo Mode’s virtual wall barrier keeps your robot away from objects you want to stay safe. Suitable for the Roomba 900, 800, 700, and 600 Series.

Why is the Roomba Virtual Wall blinking?

The Virtual Wall continuously blinks twice to show fresh batteries are needed when battery levels are low. The batteries should last for about six months in AUTO mode. Virtual Wall Accessory is only available for models 780 and higher.

Comparison of Virtual Wall vs. Roomba Lighthouse

The Roomba is a great vacuum, but sometimes it gets stuck in rooms that are separated from the rest of your house or run into furniture that it shouldn’t.

Two main types of accessories made by iRobot will help with this problem (the company that makes the Roomba). Lighthouse and Virtual Wall are the names of them.

Let’s look more closely to discover if some of these are helpful depending on the type of room or area you’d like to block off from your Roomba. Both work differently.

What Does The Roomba Virtual Wall And Roomba Lighthouse Off from Each Other?

A device called the Roomba virtual wall can be used to block off an area and stop the vacuum cleaner from entering.

A signal from the Lighthouse is being used to guide the Roomba robot vacuum cleaner to areas that require cleaning.

The Lighthouse is generally more efficient than the virtual Wall that directs your iRobot Roomba to specific zones, even if both solutions serve their intended purposes well.

Virtual Wall Lighthouse Updates

The Virtual Wall and Lighthouse were sold separately initially; however, iRobot has improved both updates and combined all features into a single unit.

Accordingly, you now have a single unit that can handle both duties with the push of a button. Once more, as time passes, the most suitable barrier is the most recent.

Compare The Most Recent Lighthouse And Virtual Wall Products

Comparing the most recent products in this guide makes more sense than the more dated, older ones. The only difference between the following models is in the batteries and compatibility.

Lighthouse Virtual Wall

Compatible only with specific Roomba 500 Series models, including the Roomba 780, 790, 877, and 880.

What is the purpose of the Roomba Virtual Wall Mode?

The Roomba will be temporarily blocked from entering a specific area by the Roomba virtual wall.

You can create a virtual wall to limit access to the entryway to the bedrooms, for instance, if you decide to run the vacuum overnight and don’t want anyone to enter the bedroom spaces.

What Functions The Lighthouse Mode On A Roomba?

Focus on cleaning power is temporarily blocked by the Roomba lighthouse. When it’s time for your Roomba to move to a new room, this barrier will disappear.

For example, if the kitchen has flooring and the living room has carpet, you may place your lighthouse controller in the entryway to prevent the Roomba from crossing the mat.

Your Roomba will keep on the carpet until it is finished, at which point it should travel to the kitchen if the lighthouse location is proper.

The Lighthouse has a halo mode that can build an undetectable four-foot-diameter barrier to shield objects like pet bowls, shoes, and other things from your Roomba.

Is Lighthouse Mode more vital than Virtual Wall Mode?

It depends on what you’re searching for since they are created to handle various duties.

With the lighthouse mode, your Roomba is less likely to get stuck on the room’s furniture or doorways and therefore is better suited for larger spaces. The virtual Wall offers a more substantial light beam that keeps your robot out of specific contexts.

Do They Function Well?

It’s not fair to compare as one uses newer, more creative Roombas. The Virtual Wall Lighthouse is an excellent replacement for older Roombas incompatible with the latest capabilities.

Both the halo mode on both devices provides adequate protection and serves their purpose.

No matter whatever iteration of Roomba and barrier you’re working on, there will ultimately be problems.

Both devices have decent battery life.

The most recent Dual Mode Virtual Wall Barrier comes with two AA batteries that, under regular use, should last for at least six months. Replace them with some rechargeable batteries if you can.

The battery requirements and potential lifespan of the Virtual Wall Lighthouse are similar. Even rechargeable versions of these batteries are difficult to replace.

Lighthouse vs. Roomba Virtual Wall

Let’s say you require the additional accessory to direct your Roomba or to protect your things. The Dual Mode Virtual Wall Barrier’s compatibility and better battery option make it better in that situation.

But the Virtual Wall Lighthouse might be more than suitable if you don’t care about protecting anything and want to use your Roomba for some extra entertainment.


The Roomba is a reasonably current device on the market. It is used in offices in addition to at home. However, we have also observed companies renting them out at high costs.

This is only one reminder of why the more recent virtual wall options have received so much interest. The robotic vacuum, the Deebot T8 AIVI Robot Vacuum, is the best Roomba virtual wall substitute in our view.
