Why Vacuum Lidar Is Your Next Big Obsession?
What is Vacuum Lidar?

Vacuum lidar utilizes laser beams to locate objects and determine their distance from the robot. This allows for accurate mapping and navigation. It helps the robot to navigate through obstacles.

Without SLAM vacuums move in random patterns, and are unable to working around furniture. With SLAM they can move in straight line and cling to the corners easily.

Accuracy and Precision

A robot vacuum that isn't lidar-equipped relies solely on visual data to navigate. While this technology still provides a reliable cleaning experience, it's not as robust in its capabilities and compatibility with smart home systems. Lidar however, on the other hand, offers a wide range of features, including obstacle detection and navigation. Lidar navigation is also more accurate and precise than camera-based systems.

What is the function of this technology? It is essentially, it makes use of a laser light to examine the room and calculate distances. The device creates a virtual map of the room by using the matrix of points that correspond to different objects and surfaces in the room. The sensor then tracks the time it takes for each signal to reach the object and bounce back, giving it an exact measurement of the distance. LIDAR is also known as Light Detection And Rangeing, is the name of this technology.

This information allows the vacuum to plan precisely its route through the space and avoid obstacles. As a result, the lidar technology of a robot allows it to avoid obstacles such as chairs or sofas that hinder its progress and complete the cleaning task faster than a robot without this technology.

This system isn't just helpful in preventing collisions, but also for identifying areas that require cleaning. This is particularly useful for larger homes or when you want the vac to pay extra attention to specific rooms, such as the living room or kitchen. It can also prolong battery life by avoiding unnecessary movements and making fewer trips to the charging station.

Some robot vacuums come with extra features that can improve performance, such as edge detection and the capability to detect different kinds of floors. Edge detection is an essential feature, particularly for robots that are used on stairs and ledges. It can prevent the machine from falling off and damaging furniture or itself. Some models allow you to manually alter auto mode when the robot encounters an edge.

There are also other smart features in robots with lidar including the ability to create virtual boundaries and define specific areas to be cleaned. Utilizing the ECOVACS HOME application it is possible to create a map for your home and draw virtual lines around the areas you want the vacuum to clean. This is useful for rugs with high-end materials or small spaces that are difficult for the robot to get into. The robot will follow the designated routes and only touch what is required, thus avoiding the frustration of a missed spot.

Real-time Mapping and Navigation

Contrary to navigation systems that employ cameras lidar is capable of mapping the surroundings in real-time. This gives robot vacuums an improved ability to navigate spaces and avoid obstacles, which reduces the frequency of cleaning and omissions, while shortening the cleaning process time. Lidar-equipped robot vacuums are also able to perform better in areas with different floor surfaces as they can recognize the patterns and textures. Unlike camera-based systems, lidar sensors aren't affected by changes in lighting conditions and can identify objects on flat surfaces or even behind glass.

In addition to its capability to map the surroundings, vacuum lidar can determine its own location within a space, and therefore plan its path in real-time. It then moves through the room in a planned way that covers all edges and corners. It also detects the presence of various objects and determine their distance and height from the robot.

While lidar has drastically improved the capabilities of robotic vacuums, the technology remains somewhat limited in terms of its accessibility. The cost of Lidar sensors has been a challenge but constant advancements could make the technology more affordable in the future.

The top DEEBOTs that incorporate mapping technology have a variety of features that ensure your home is cleaned thoroughly. For example the Dreame F9 uses 14 infrared sensors to identify obstructions and obstacles. It also has the ability to automatically alter its route if it encounters an object on the stairs, or when it approaches a doorway. It will also activate the cliff sensor to prevent it from falling off the staircases.

Other technologies, such as gyroscopes or cameras, are able to perform similar tasks on the vacuum cleaner. Gyroscopes can prevent the robot from bumping against objects and can also help create a basic map. They're not as precise as systems using lasers, such as SLAM or Lidar. However, they do offer a good quality of navigation at a much lower price point than the other options. Cameras can also be a good alternative to laser systems for mapping and navigation since they require less maintenance.

Obstacle Detection

Whether you want to avoid getting tripped over by toys or clean up pet hair, vacuums equipped with lidars are capable of detecting obstacles and navigate around them. The sensors scan and map the room with laser beams, determining the amount of time required for the light to bounce off the objects and return to sensor. The sensors then create a 3-D map of the space that provides real-time distance measurements, and removing the requirement for cameras.


While robot vacuum cleaner with lidar are extremely accurate, they do have some limitations. They can be prone to mistakenly thinking clear or reflective surfaces for obstacles, have difficulty detecting very small objects, and have a difficult time working in rooms with complex layouts. These limitations could affect the navigation abilities of a vacuum cleaner. It could miss certain areas of the floor or fail to recognize an item that is in its direction.

Manufacturers may combine several mapping technologies to give the best navigation experience. Certain models, for instance, feature both Lidar (Localization and Mapping) and SLAM. This technology is expensive however, it also offers the most precise navigation. It lets robots create a map of the house and allows them to clean in a systematic manner and not just randomly.

Other mapping techniques include cameras and gyroscopes. These systems could prevent robots from hitting objects and help them form an initial home map, however, they aren't able to do the same as laser-based systems, such as Lidar and SLAM.

Your personal preferences and your budget will ultimately determine the kind of map system you choose. Some people might prefer the convenience of a robot equipped with gyroscopes, whereas others want a more advanced navigation system that can cut out the need for manual intervention and create more precise maps. Try out various vacuum robots to find which one is best for you. Also, think about the features you value most.

Easy Maintenance

With the companion app, you can create virtual boundaries to keep it out of certain areas or to set room-specific cleaning schedules. You can also see its progress, change its power settings, and check the status of its HEPA filter, brushroll and side brushes. The dirt compartment is located under the glossy black cover at the top. It is recommended to empty it into a garbage container when it's full. It's also simple to stop and restart cleaning sessions, and share the vacuum with other household members.
