What Makes a Robot Vacuum Cleaner Best?

The most effective robot vacuums have a powerful motors and a set of bristles or rollers that are durable. They also have large dustbins and a long battery life.

Certain models map homes using smart mapping. They can pause to recharge and then pick up cleaning where they left off. They can set up no-go zones and also identify different surfaces.

Object Avoidance

Object detection is an essential feature for robot vacuums, as it helps them avoid getting into small objects like cords, toys, socks or shoes that aren't on the floor, but on furniture. The machines use cameras built into the system to identify objects that are listed in an AI database, and then teach the vacuum to avoid them. The Eufy S1 Pro, for instance, makes use of a variety of sensors that include 3D Time of Flight (sending light pulses to determine the distance and depth of nearby objects) and 3D Structured Light (beaming a pattern of lights onto the room and analyzing the light distortion to create an image) to effectively steer clear of obstacles.

A more recent addition to the obstacle avoidance arsenal is artificial intelligence and visual interpretation, which enables robots to more easily identify and understand what they're encountering. This software works with cameras that are either dual or single to observe the world around them and analyzes it in real time. The ECOVACS DEEBOT uses this software to detect up to 30 types of objects including cables, shoes, and pet poop.

Some models utilize LiDAR to navigate. The technology emits lasers and determines the amount of time it takes to bounce off surrounding surfaces in order to create an 3D map. This can be used to identify furniture, walls, and even stairs. However, it may not work as well in dim lighting or when working with transparent or reflective objects.

Whatever sensor or cameras are used regardless of the camera or sensor used, a long-lasting battery is essential to ensure that your robot can complete an entire home without needing to return to its dock to recharge. Find an option that runs for a minimum of 80 minutes or more, based on the size of your living area.

Self-Emptying Bases

Some robot vacuum cleaners have self-emptying bases. This can decrease the frequency that you have to empty your trash. They're considered a premium feature, and usually add to the overall price of the robot.

The best robots come with bases that can hold bins or a removable dustbin. You can open it and empty it when full. This can help you save time by cutting down on the time you spend worrying about the time to empty a bin.

Self-emptying bases are present on all the robots we've reviewed in our review, except for the basic Roomba I3+, which does not have one. That's a shame, because this robot is an extremely strong performer. It had the best results in mapping of all the robots we tested and it has superb navigating abilities. It also has excellent mowing power and docking station that can automatically empty the water tank when it is required.

It doesn't have iRobot's advanced obstacle avoidance technology and digital keep-out zones, but it can get tangled up in cables and rugs, and is unable to see rogue shoelaces or socks. However, it's an excellent choice for an apartment that is small and well-maintained.

Other strong points of the product include its aforementioned navigation technology, which includes drop sensors and bump sensors, as well as its ability to map out the entire house with cameras and a laser. It is easy to use, has a range of options and settings and is a great choice for cleaning or mowing. Its smart-home functionality allows it to be controlled by voice commands made using Amazon Alexa or Google Assistant. That can make it easier to use if have multiple tablets or smartphones and don't want to pick up the remote.

App Controls

Certain robots are able to connect to Wi-Fi, which allows you to control them with your tablet or smartphone. This feature is particularly beneficial in homes with a lot of floors, where you may have to navigate down a staircase before the robot can get to the bottom. It also removes the need for a long cord, which means you can move furniture freely without worrying about your robot getting caught in the cord or running out of power while cleaning.

The app functions as central control point to monitor and schedule tasks. The app lets you customize the cleaning mode, power and the water level of your robot cleaner. This feature is particularly useful in homes with various floor types, for instance, carpet and tile because you can set the robot to clean each room with the appropriate power and mode.

Certain models have an inbuilt camera that can send a live feed to the app. These models are great for pet owners as well as those with small children who wish to watch the robot while it functions. Other smart robots have sensors that detect when they've reached the edge of a room and then return to their base to dock. This stops them from overrunning an area and makes sure they have cleaned all surfaces in your home.

Some models can empty the dustbin automatically and even wash their mop heads and blow dry them between cleaning sessions. This will reduce the need for manual maintenance, and the robot cleaner will function better for a longer time. There is also a model that has an extended battery duration which allows you to avoid the hassle of having to recharge mid-cleaning.

Sensors

Many robot vacuums come with sensors that let them navigate through your home. They can be used on carpets, area rugs as well as hard floors like wood and tile. They're not the same as a full-size, upright or canister vacuum cleaner, but they offer excellent suction on dirt and dust. They are a fantastic way to keep the floor clean between deep cleanings using the traditional vacuum.

Sensors let the robot navigate around your home by detecting obstacles, and avoiding falling off steps. They also allow you to set virtual and physical "no-go" zones using the feature known as boundary strips or virtual walls (like the ones used by eufy) to block the robot from entering certain areas of your home. Some robots come with cliff sensors which alert you when your robot is set to fall into an obstacle.

The kind of navigational system the robot utilizes is determined by your budget and home layout. Some of the most sophisticated robotic vacuums use LiDAR-based sensors to scan and map rooms, ensuring accurate and efficient navigation. These systems are expensive, but they provide the most effective results. The budget-friendly models that have basic bump navigation systems aren't as precise and may miss certain places. These models are good at avoidance of major obstacles, but they may fail to spot dirt in crevices and around baseboards.

Look for a model with an extra-large dust bin as well as a long battery lifespan. You can find models that dock and recharge and then pick up where they left off. This saves time. In addition to navigation it is possible to make the most of your robot vacuum by making sure you have everything ready for each cleaning session. Check that power cords and toys are tucked away and away from the robot's path. Also, empty the bin between each cleaning. Clean the sensors and charging port to ensure your robot is in good health.

Navigation

The best robot vacuums use mapping technology to create an electronic map of your home prior to the initial cleaning session. It helps them to recognize patterns like carpets or hard floors, and ensures that all areas are clean. It also prevents your robots from cleaning the same areas over and over again and can increase efficiency and decrease battery consumption. A majority of top models let you save a map to use in the future. This is great for large homes.

Most robotic vacuum cleaner best vacuums have some sort of obstacle avoidance system that stops them from slamming into cords or socks, or shoes. However, these sensors do not always recognize smaller objects. A few years ago manufacturers began adding additional sensors to their robots, allowing them identify and avoid household items that traditional sensors could not. These include cliff and wall sensors, which operate by bouncing infrared light beams off surfaces to calculate distances.

Some sensors are built directly into the robot base, however, others require being purchased separately. These sensors assist the robot navigate in a safe manner and avoid falling down steps, and keep away from clutter. Some models even have anti-drop sensors, which automatically stop the robot from hitting walls and furniture.

LiDAR mapping the most advanced navigation system available is a feature that you should look for when purchasing robot vacuum. The system makes use of a spinning sensor mounted on the robot to map your home. It can map your home's layout by bouncing infrared beams off your furniture and walls. This helps to plan efficient routes and clean your entire house.
