Does Roomba Learn The Floor Plan?

For a robotic vacuum cleaner introduced in 2002, Roomba is gaining considerable attention today. These vacuum cleaners are not only popularly accepted for their amazing features and cool tools, but also because of their convenience for use.

This does not, however, mean that people do not have questions about Roomba that bothers their hearts. People keep asking about its functionality, practicality and reliability.

Usually, a unique issue is the question about whether or not Roomba vacuums can recognize room layout. Does roomba remember room layout?

This article will answer this and other vital questions about these remarkable autonomous robotic cleaners known as Roomba. Make sure you read it to the very end.

How Does The Roomba Map a Room?

Can a Roomba map out a room?

Yes, it can. Now, the more important question is “how does it do it?” Older models do not have this ability, so it is only reasonable that people are sceptical about this one. Mapping out a room comes with many advantages, and ease is only one of them.

How Does The Roomba Map a Room

Generally, the Roomba products, both older and newer versions come with sensors that allow them to navigate the room. However, newer versions still remember the room layout the next time they are used to clean a room, while older versions do not.

Why is this?

Newer models come with some mapping features that allow it to map the room and move around it accurately. Below are explanations on some of the mapping features that the best models of Roomba possess.

1. Infrared Receiver

An infrared receiver is used to control devices by sending signals. Roomba has an infrared receiver that allows it first to send out signals. They then wait a while for a reply, and this is what enables the device to determine the size of the space. It also helps the device to have an idea of all the obstacles, their location, and the amount of time it will take to clean the room.

2. Bumpers

These are what help Roomba to move in such a way that it avoids obstacles. It is an object sensor that helps the machine to clean the room while avoiding obstacles, and this feature is particularly useful for rooms or areas with plenty of furniture. Only newer models, most of which are expensive have this feature.

3. Cliff Sensors

Cliff sensors are infrared emitters and a navigation tool that actively searches for cliffs so that it could prevent the machine from falling off them. It also works to prevent them from falling down the stairs.

4. Wall Sensor

Roomba vacuums also come with wall sensors and they help the machine to detect walls close by. When the device discovers any wall, it only cleans near areas to avoid bumping into the wall. While older versions stray from the walls, the newer versions clean along them.

5. Cleaning Paths

Advanced Roomba models determine their cleaning path as they have been programmed to do so. Usually, they start cleaning in an outward spiral until they get to the perimeter of the room. Others do it in a snaking pattern. The point of all this is to clean the whole floor within an amount of time.

How To Operate Roomba?

How To Operate Roomba

Roomba can be carried manually to the room that needs cleaning. A particular button is pressed to commence the cleaning which is merely the standard cleaning program. However, newer models have introduced other additional features.

The spot mode allows the device to clean a small area making use of both outward and inward circle movements. The max mode gets the standard cleaning algorithm going right until the battery is exhausted. The dock mode feature came with the third generation model. It instructs the robot to look for a charging base for it to recharge.

These various modes are available depending on the model. The device has sensors and mapping features that help it avoid obstacles and barriers, avoid cliffs, detect virtual wall signals, and charge itself. Its cleaning time differ depending on the model and room size.

Newer generations can calculate beforehand the amount of time it takes to clean up a room. They are also able to map out the room layout and recognize it the next time they clean.

How Do Virtual Wall Units Help?

virtual wall roombaRoomba is smart enough to do all that it needs to do by itself. However, you still need to make some decisions on its behalf. To aid the device’s activities, you need to get rid of all small objects from the space.

This way, Roomba will neither get stuck on them nor try to vacuum them as well. Also, it is vital that you tell the machine where it shouldn’t go.

The function of virtual wall units is to keep your robot within certain boundaries or limits. With the receiver on its bumper, Roomba can detect the infrared signal that the virtual wall sends. Immediately the machine picks the signal, it recognizes it as a sign to turn around and continues its work elsewhere.

Roomba Power Source

Roomba runs on a removable NiMH battery. This battery can be recharged from a wall power adapter. Newer models like the second and third generation models thrive on a self-charging home base that the device searches out at the end of a cleaning process using infrared beacons.

It usually takes about three hours to charge using the self-charging home base.

Does Roomba Work on Carpets?

Roomba is not the best choice for carpets, especially thick ones. First, a Roomba lacks a beater bar that is aggressive enough to loosen all the dirt in the carpet, and suck it up. Its battery cannot withstand the drain that thick carpets require. Also, the Roomba robot tends to make much noise when used in a carpeted area.

There’s also the tendency that the machine will get stuck. Besides, using a Roomba robot on a thick carpet will make the entire process slow, annoying, and inconvenient.


Though not all Roomba vacuums can recognize a room’s layout, the ones that can do it accurately. Even so, different models have peculiar features that are meant to make your cleaning exercise an easier and enjoyable one. With Roomba, you won’t need to be as involved as the robot is capable of doing most of the work by itself.

Roomba aimed to make life easy, and it is not a bad thing to spend your money on. After all, our aim is to be as comfortable as we can afford and Roomba are cool equipment to invest in. They’ll save you much stress, and valuable time.
