Does Roomba Work In The Dark?

Yes, Roomba works in darkness too. Most Roomba models have been equipped with various sensors that let them move and clean in areas with poor lighting.

Even in total darkness, the Roomba can navigate around obstacles because of a variety of sensors, including infrared cameras, microphones, and cliff sensors.

In addition, Roomba models with advanced functions such as mapping and GPS navigation can also operate effectively in low-light conditions. 

However, it’s crucial to remember that certain Roomba models could not operate as well in total darkness as they may.

How Does Roomba Work In The Dark?

Now you’ve got the answer to your question, Does Roomba Work In The Dark? But wondering what makes it possible to navigate the objects in dim lights or dark too.

Here are some of the features and sensors your Roomba holds to make it work in the dark too:

Use of Gyroscope-Based Navigation For Memorizing The Space

The Roomba Vacuum Cleaner uses gyroscopic navigation to memorize the room’s layout and build a picture of it. The wheel rotations, curves, and barriers in the room are used to create a picture of the room.

Imagine being blindfolded and trying to remember how many steps are left, right, front, and back until you get to the entrance. You can simply return to your starting position if you remember the route backward in full detail.

It does not qualify as “mapping” in the sense of drawing a diagram of the world. Even though more advanced orientation systems are now available, gyroscope-based Roomba vacuums typically still perform well.

Use Of Camera And Software For Smart Control

iRobot’s Roomba vacuum robots are compatible with the company’s vSlam technology. The device’s top camera has its focus set on the ceiling. That’s why Roombas navigate their way around by memorizing the ceiling.

Most Roomba models are several centimeters shorter than their rivals with laser towers, which is a huge benefit in daily life. Because there is no structure to become trapped in, the risk of doing so is greatly reduced.

The Laser Tower For Navigation 

These days, a laser system is standard on most robot vacuums. A “laser tower” mounted on the room’s head takes pictures of its surroundings as a guide as it navigates. 

This data may be accessible via an app and included in regular cleaning procedures. After a thorough scan of the area, your Robot Vacuum Cleaner can work in the dark too, and you can additionally set up off-limits areas for it. 

This kind of projection may be used to display whole floors of buildings. Additionally, the user interface is simplified since picking the desired cleaning area is all required to start.

Infrared Detection System For Detection Of Objects

Nearly the same principles govern how the infrared system operates. In this case, an infrared sensor is used instead of a laser to scan, and a digital representation of the space is produced as well.

Light is not necessary for navigation when using either lasers or infrared.

They have Impact Detectors To Work In the Dark

No matter what other orienting devices a vacuum robot may have, it will always have bumpers. When the Roomba bumps against anything, the bumper or bumpers detect and release the impact. 

The sensors detect the force of a hit and prevent damage to the devices and nearby furnishings. However, the impact sensor double-checks that the Roomba isn’t getting trapped.

Which Roomba Model Has the Best Nighttime Performance?

The iRobot Roomba s9 uses light detection and ranging (LIDAR) technology and s9+ to simplify cleaning areas with poor lighting. This Roomba can do a 25-times-per-second forward scan to locate and avoid obstructions in its cleaning route.

The Roomba s9+ can also map its immediate area using its advanced smart mapping technology. With this information, the robot will have an easier time figuring out where it is and where it needs to go.

The Roomba may be designed to avoid certain places, even in the dark, by designating them as keep out zones.

Which Roomba Models Need Light To Work?

Does Roomba Work In The Dark?

All Roomba units need some light when cleaning. Only a few models can successfully clean in total darkness. More advanced Roomba machines have superior nighttime performance. 

Roomba models from the 600, 900, and e series need greater light than those from the i, j, and s series.

Roomba ModelRequires Light to Work
Roomba i7+No
Roomba s9+No
Roomba 960No
Roomba e5No
Roomba 675No

How Much Light Is Required To Clean With A Robot Vacuum?

A camera-equipped Roomba requires 40-80 lumens of light. That’s 10–20 percent of the power of a standard 40 Watt bulb.

I used a Roomba 900 series robot vacuum to test it. When the percentage dropped below 10%, I began getting inaccurate results, and when it dropped below 5%, it stopped operating entirely.

When the light level drops below around 5% of what a 40-watt bulb normally puts out, it becomes too dark for the human eye to function properly.  

Thus, it can be concluded that camera-equipped Roomba doesn’t need a lot of light and that some models also use other sensors like lidar or lasers.


Can I Use Roomba In The Dark?

Roomba is made to work even when it’s completely dark. It can successfully travel and clean in the dark because of its array of sensors.

Will Roomba Be Less Effective At Cleaning If The Lights Are Out?

Roomba might not clean additionally in low-light areas because it might not be able to find dirt and trash as well as in well-lit areas. 

However, the Roomba can still do a good job of cleaning since its sensors are built to function in various light exposure situations, from bright sunlight to pitch blackness.

Do The Lights Need To Be On For Roomba To Work?

To run Roomba, you don’t even need the lights on. Because Roomba’s sensors have been set up to work in a wide range of lighting levels, the robot can successfully go and clean without any extra light.


The Roomba robot vacuum cleaner has cutting-edge sensors that allow it to move around obstacles and successfully clean your floors at night.

It offers an incredible selection of features, including multi-surface brushes, cutting-edge filtration systems, and strong suction, that enable it to fully clean your house.

So, if you were worried about Does your Roomba work in the dark or not? Then Roomba is a fantastic option and an effective vacuum cleaner that can function effectively even in dim lighting.
