What is Vacuum Lidar?
Vacuum lidar makes use of laser beams to identify objects and determine their distance from the robot. This allows for accurate mapping and navigation. It also makes it easier for the robots to navigate through obstacles.
Without SLAM vacuums are prone to move in random patterns and struggle to maneuver around furniture. With SLAM they can move in straight lines and stick to the corners easily.
Accuracy and Precision
A vacuum cleaner that doesn't have lidar can only navigate using visual data. This technology is still reliable, however its capabilities and compatibility are limited. Lidar on the other hand, offers many features, including obstacle detection and navigation. Lidar navigation systems are more precise and accurate than camera-based ones.
How does this technology work? It utilizes a laser to scan the room, and measure distances. The device creates a virtual room map using a matrix that corresponds to various objects and surfaces in the room. The sensor measures the time taken for each signal to hit the object then bounce back to give it a precise distance measurement. This is what is the reason for the name - LIDAR or Light Detection And Ranging.
This allows the robot vacuum to accurately plan its route through the room and avoid obstacles. A robot with lidar technology can stay clear of obstacles like chairs or sofas and clean up quicker than a vacuum without this technology.

This system isn't just beneficial for preventing collisions but also for identifying areas that require cleaning. This is particularly useful for homes with larger spaces, or if the vacuum cleaner should be focusing on specific areas, such as the living room or kitchen. This can also help conserve battery by avoiding unnecessary movement and making fewer trips to the charging station.
Some robot vacuums are also equipped with additional features that can enhance their performance, such as edge detection and the ability to recognize different floor types. Edge detection is an important feature for robots that could be used on ledges or stairs because it will stop the machine from falling off and damaging furniture or the machine itself. Some models even allow users to manually override the auto mode when it encounters an edge.
There are other innovative features that robots with lidar have, such as the ability to create virtual boundaries and designate specific areas to be cleaned. Using the EcoVACS HOME application it is possible to make a map for your home and draw virtual lines around the areas that you would like the vacuum to clean. This can be useful if you have expensive rugs or tight spaces that are hard for the robot to get into. The vacuum will only clean the areas that are needed and follow the designated routes. This will save you the frustration of snagging a spot.
Real-time Mapping and Navigation
Lidar can map the environment in real time, unlike navigation systems that depend on cameras. This makes robot vacuums more efficient in their ability to navigate around spaces and avoid obstacles, which in turn reduces the need for repeated cleaning and omissions, as well as reducing the time required to clean. Lidar-equipped vacuums also have superior performance in areas with different floor surfaces because they are able to recognize the various patterns and textures of these floors. Lidar sensors are less affected than cameras by changing light conditions. They can detect objects even on flat surfaces or behind glass.
In addition to being able to map the environment, vacuum lidar can determine its own position within a space, and thus plan its path in real-time. It can then move around the room in a planned way, covering all edges and corners. It also detects the presence of multiple items and determine their distance and height from the robot.
The lidar technology is somewhat limited in regards to its accessibility. Lidar sensors are expensive, but ongoing improvements may make them more affordable in the future.
The most effective DEEBOTs equipped with mapping technology come with a range of features to ensure that your home is cleaned thoroughly. The Dreame F9, for example, uses 14 infrared sensor to detect obstacles and obstructions. It can also automatically adjust its route when it comes across an object on the stairs or approaches the doorway. It also activates the cliff sensor, which will prevent it from falling off staircases.
Other technologies, like cameras or gyroscopes are able to perform similar tasks on the vacuum cleaner. Gyroscopes are a simple way to stop the robot from hitting objects, and they could assist in creating an initial map of the surrounding. They're not as precise as systems that use lasers, like SLAM or Lidar. They can nevertheless provide a high quality of navigation, but at a lower price than other alternatives. Similarly, cameras can be a viable alternative to laser-based systems when it comes to navigation and mapping, because they do not require any maintenance.
Obstacle Detection
If you're looking to prevent tripping over toys or cleaning up pet hair, vacuums equipped with lidar are capable of detecting obstacles and navigate around them. This is because the sensors utilize laser beams to scan and map a room, measuring the time it takes for the light to bounce off objects and return to the sensor. The sensors can generate a 3-D map of space which provides real-time measurements and eliminate the need for a camera.
Lidar sensors are extremely precise however, they have a few limitations. These include a tendency to confuse reflective or clear surfaces as obstacles and a failure to detect small objects and the difficulty of working in rooms with complicated layouts. These limitations could affect the navigation capabilities of a vacuum cleaner, leading it to miss areas of the floor or fail to recognize an object in its route.
Manufacturers often combine multiple mapping technologies in order to give the best navigation experience. For instance, certain models come with both Lidar and SLAM (Simultaneous Localization and Mapping). This technology is expensive however it provides the most precise navigation. It allows the robot to begin by creating a map of your home, making sure that it cleans your home in a systematic way rather than randomly.
Other mapping techniques include cameras and gyroscopes. These systems could prevent robots from hitting objects and aid in forming the basic home map but they're not the same as laser-based systems such as Lidar and SLAM.
Your personal preferences and your budget will ultimately determine the type of mapping system you choose. Some people prefer a robot that has gyroscopes while others prefer an advanced navigation system that has more advanced features. Try different vacuum robots to determine which one is suitable for you. Also, think about the features you value most.
Easy Maintenance
With the companion app, you can designate virtual boundaries to keep it out of certain areas or set room-specific cleaning schedules. lidar based robot vacuum can also track its progress, alter its power settings and view the status of its HEPA filter as well as the brushroll and side brushes. Its dirt compartment is easily accessible under a glossy black cover on top and should be emptied over the garbage can once it fills. You can also stop and resume cleaning sessions, and share the vacuum cleaner with other household members.
