Does Roomba Need Light? [With Examples]

Will Roomba work in the dark? The plain and simple answer is that it depends. 

Even though the majority of robot vacuums can work or function in total darker, several models require light for their cameras to see where to go. As for robot vacuums that don’t feature cameras, there are some problems with getting excessive sunlight that can leave their sensors confused.

What makes robot vacuums function in the dark

If you are wondering if robot vacuums such as Roomba can clean dim-lit rooms or those that are completely dark, again, the safe answer is that it will depend. Although many models function in complete darkness, some still need light for their cameras to see.

That ability to map the room even with no light is being carried out by the navigational technology of the machine. This software identifies where the robot will go according to how it will interpret all the images that it sees through the camera.

The higher-end models use the state of the art navigational technologies for the detection of walls and bumps that allow them to work longer even with no human intervention. As expected, however, a machine that can work outstandingly in the dark always comes with a certain price tag.

This is why before you even start shopping for robot vacuum cleaners, it is important to know how much your budget will be. After that, you can start checking online to get some idea about the available models.

Always read the reviews from the users for you to know whether or not the device suits your needs or budget. You can also refer to tech review sites where you can find helpful answers and useful recommendations when it comes to robotic vacuum cleaners.

What is the best Roomba model that works in the dark

The iRobot Roomba s9+ makes use of light detection and ranging or LIDAR technology that making this an outstanding option if you want to clean dark rooms.

It features enhanced sensors that can repeatedly scan ahead at the rate of 25 times per second to identify obstacles or hindrances present in the path that will be cleaned.

The model also comes with intelligent map recognition and recalls past tracks to prevent it from going back and forth. It also has a Keep Out Zones feature that allows you to set a virtual wall for keeping the device within the controlled spots.

What Roomba models require light

The Roomba 900 series such as the 960 require light for them to work well in dark rooms and provide good cleaning results.

Why does your Roomba fail to clean your entire house

If you own any of the Roomba 900 series models and it doesn’t clean your entire home, it can be because of the amount of light present in the house.

When the light is insufficient, these Roomba vacuums cannot work correctly and properly. These robotic vacuums make use of cameras to see your house as you would and when the room is in complete darkness, they won’t be able to clean.

For this reason, it will be better to leave on a lamp or any type of light source to allow them to see.

One more problem can be excessive light. When the room gets a lot of natural light, the sun’s infrared may end up confusing its sensors because it uses infrared on the beacons. The beacons are those tower things running on batteries that instruct the robotic vacuum to stay away.

How much light do robotic vacuums need

Some auto-on LED night lights will fit most users’ needs. The night lights turn on once it becomes dark and will stay on all night long. This is a constant light source that matters the most for the robotic vacuums instead of brightness.

Does too much sunlight affect robotic vacuums

If you open your windows to let the natural light in, your robot vacuum may work much harder than it should be.

This not only affects robot vacuums with cameras but also those that make use of infrared. Many robotic vacuums in the market use invisible walls that inform the robot not to go to a room and these beacons are using infrared. Since the sun gives off plenty of infrared light, this might confuse the robotic vacuum. Your robot vacuum may even refuse to clean around those sun rays on the floor for this reason.

The best thing that you can do here is to let your robot vacuum clean in rooms with the windows closed or if the sun is not out.

Sudden light changes such as the setting of the sun or turning the overhead light on can freak out a robot vacuum, especially if this comes with a camera. You will be fine if you let the device work constantly in just the same amount of light.

Always keep in mind that robot vacuums look at walls instead of floors when cleaning. They won’t be able to identify where they have been or where they are if the walls are not that lit enough.

Can robot vacuums clean dark floors

Most of the time, robot vacuums can also clean dark floors with no issues at all. It is because the sensors don’t look at the floors. Instead, they focus on walls and other vertical objects to stay away from bumpers. The process lets the machine continuously clean the floor provided that its spatial sensors work correctly. The floor’s color doesn’t matter in any way.

But, several users are complaining about certain models that don’t work on black carpets. For example, there are Roomba robot vacuums, particularly Roomba 570, that refuse to work on dark-colored or black surfaces. Some models’ cliff sensor mistakenly identifies the dark colors as edges and will refuse to clean them. Sadly, the company hasn’t come up with a permanent solution for the issue.

If you want a robotic vacuum that can work in the dark, be ready to spend some extra cash to get the best model out there.
