Does Roomba Remember Room Layout? How It Maps A Room?

If you have stumbled upon this article, we guess it will be best to say that you are pretty new to the idea of having a smart room cleaner.

Well, for the advancement of technologies, we have been blessed with many smart devices that aim to make our life a little bit easier. And Roomba is one of them.

However, as you are not familiar with this device, you might wonder does roomba remember room layout and how it maps a room. But as you have stumbled upon this article, there will be no need to wonder anymore because we will give the answer to all your questions here. So, carry on reading!

Does Roomba Remember the Room Layout?

This will depend on the model of the Roomba. And you might not know this, but there is an extensive lineup of Roombas. Usually, the older models cannot remember the layout of the room and will only use the sensors to navigate around. It will only turn when it senses an obstacle and will not memorize the layout.

That being said, the new models will come equipped with new technologies, which would make them capable of learning the room layout. That is why they are a bit expensive than the older models. Basically, they will boast an integrated memory, which will let them store the entire layout of the room.

But why do those models remember the layout? Well, it makes the task of navigating around the room easier. It will not have to rely on the sensors completely to move around. And by remembering the layout can also do a better job in cleaning the areas where the sensors might not give a proper reading.

In addition to remembering the layout, these devices can also remember the exact details of some places. For example, they will remember that one obstacle that never moves or moves. Also, they will keep the memory of cliffs in their memory. For that reason, they can do a better job of cleaning the room.

Are All the Roombas Capable of Remembering the Layout?

Not really. As we have mentioned, the older models cannot remember the layout of the rooms as they lack the technology and the memory to store it. They will only rely on the sensors that are on the body to move around. And when the sensors sense an obstacle or cliff, it will make the device turn.

For example, some of the models, the 900 series, hold the capability to learn up to 10 different floorplans. They have a good amount of memory capacity to store all of that data. And due to having that capability, it will be possible to take them to new places and make them learn the layout.

On that note, some of the models will also rely on other means to learn the layout. They might use Alexa and Google Assistant. But the older models do not have any of this ability. For that reason, we would recommend spending the extra bucks and get all the convenience that modern technology has to offer.

How Roombas Map a Room?

The newer models have a smooth mapping system. They are more technical and maps the room space by using different sensors and taking the help of different features that they have built in. However, the old ones will not be as advanced as the new ones.

How Roombas Map a Room

Nevertheless, the main thing that we are here to discuss is how do the new models actually map a room. Well, these are the things that they usually use:

Infrared Receiver

There is an infrared sensor on the body that will basically control the overall movement of the device. It sends out signals and waits for them to come back. The longer it takes for the signals to come back, the farther the obstacles are. And the shorter the time they will take, the closer the obstacles are.

Infrared Receiver

During this waiting period, the infrared receiver also collects other information. It will determine the time, size, and location of the obstacles. And the device will use these data to properly navigate and map the room.

Bumpers

To avoid bumping into any sort of obstacles, the Roombas uses bumpers. These will basically allow the device to maneuver around the room without crashing directly into any of the furniture or objects that might be in the room. Also, Roombas are going to use these to properly map the area around.

Wall Sensor

There is a wide array of sensors on the device. And one of them is the wall sensor. This sensor acts like it is named. It will detect the walls and move the device around when there is one in front. Also, it will make it much easier for the Roomba to map the room.

On that note, the newer models will equip better wall sensors. Those will make the device capable of cleaning right along the wall without making the device bump right into it.

Cliff Sensor

Another set of sensor that the device use is the cliff sensor. This will basically stop the device when there is ledges, cliff, and stairs in front. And the device will also remember the location and map it into the memory. As a result, it will avoid going full speed in those areas.

Cliff Sensor

Cleaning Paths

Finally, it will map the cleaning paths and remember them as well. However, only the newer models will come with this feature. The older models will not have this one. And in this feature, the device will use its sensors and remember the cleaning paths it took during a cleaning cycle.

Cleaning Paths

After that, it will use that information from the cleaning path for the other cleaning cycles. It will basically map out the most efficient path and take them on the other cycles. As a result, it will be capable of cleaning the entire area without wasting too much battery juice.

How Long Does It Take for a Roomba to Learn the Entire House?

As we have mentioned above, some of the models are better than others when it comes to mapping. Especially, the 900 series models will come equipped with a higher amount of memory to store the data of 10 different plans. So, the time that it will take for the mapping will depend on the model and the size of the house.

Additionally, the Roombas will basically use the infrared sensor for most of the mapping. And it will collect multiple data from that sensor to map out the entire room. That also means that the Roomba can not simply accurately map the room in a single cleaning cycle.

However, it will process the data collected from the cliff and wall sensors faster than the others. That is why you will notice the Roomba slowing down near a stair in the very second run. But the time required to process the data from the infrared sensor will take a bit of time.

In a nutshell, as it requires quite a time for the device to process all the collected information, it might have an incomplete map of the rooms in the first few runs. But with time and with different new data collected from the other sensors, it will become better at mapping the room and will be able to make it complete.

Do Roombas Lose Charge Quickly While Trying to Map a Room?

Yes, they do lose charge reasonably fast while trying to collect all the data from different sensors. However, with time they will be able to process the data faster. Also, thanks to the cleaning path technology, they should take the shortest and the most efficient path during the cleaning cycles.

On that note, while taking the efficient paths, it will avoid circling back into the same place. That means the battery will be conserved, and the device should be capable of using all of the juice efficiently. Also, during the first few runs, it might go back and forth to the charging station quite frequently.

Final Words

Hopefully, now you know does roomba remember room layout or not. Also, we hope that we were able to give you an idea regarding how it maps a room and how long it takes for the device to map the entire house.
