What Makes a Robot Vacuum Cleaner Best?

The top robot vacuums feature an efficient engine and a sturdy set of bristles or rollers. They also have large dustbins as well as a long battery life.

Certain models map homes with smart mapping. They can stop to recharge and then resume cleaning where they stopped. They can even define no-go zones, and even identify different surfaces.

Object Avoidance

Object detection is an essential feature of robot vacuums, as it helps them to avoid running into small objects such as cords, toys, socks or shoes that aren't on the floor, but rather on furniture. These systems employ an integrated camera to recognize objects in an AI database, and then teach the vacuum to avoid them. The Eufy S1 Pro, for example, uses a combination of sensors including 3D Time of Flight (sending light pulses to determine the distance and depth of the surrounding objects) and 3D Structured Light (beaming a pattern of lights onto the room and then analyzing the light distortion to create an image) to efficiently steer away from obstacles.

A new addition to the obstacle avoidance arsenal is artificial intelligence and visual interpretation, which enables robots to recognize and understand what they're encountering. The software makes use of cameras that are either double or single to observe the world and analyze it in real time. This software is used by the ECOVACS DEEBOT to detect up 30 different objects, which includes shoes and cables.

Certain models employ LiDAR to navigate. The technology emits laser beams and measures the amount of time it takes for them to bounce back off nearby surfaces to create a live, 3-D map of the surroundings. This is useful for finding furniture, walls, and even stairs. However, it may not work as well in low lighting or with reflective or transparent objects.

Whatever sensor or cameras are used regardless of the camera or sensor, a long battery life is crucial to ensure that your robot can completely fill your home without having to return to its dock to recharge. Look for models that can run for at least an hour or more, based on the size of your living area.

Bases that self-eliminate

Some robot vacuum cleaners come with self-emptying bases, which can reduce the frequency with which you need to empty your bin. They are considered a premium and add to the cost of a robot vacuum cleaner.

The most effective robots have bases that are able to hold either bins, or a removable dustbin. It is possible to open the bin and empty it when full. This will reduce the amount of time you're worrying about when to empty your bin and could make a significant difference if you have a high-mess household.

All of the robots we tested have self-emptying bases, except the Roomba I3+. This is a shame because this robot is extremely efficient. It got the highest mapping performance of all the robots we tested and it has excellent navigation capabilities. It has a good mowing ability and a docking system that will empty the water tank automatically if it is needed.

It's not equipped with iRobot's innovative obstacle avoidance technology or digital keep-out zones it is hung over cables and rugs and doesn't have the ability to detect the stray socks or shoelaces. That said, it's the perfect choice for a small, well-maintained house.

Other strengths include its aforementioned navigation technology, which includes bump sensors and drop sensors, and its ability to map out the entire house with cameras and a laser. It's also simple to set up, offers a wide variety of settings and modes, and offers outstanding mowing and vacuuming performance. Its smart-home feature allows it to be controlled via voice commands made using Amazon Alexa or Google Assistant. This can make it easier to operate in the event that you own multiple smartphones or tablets, and don't wish to purchase the traditional remote.

App Controls

Some robots connect to Wi-Fi, allowing you to control them with your tablet or smartphone. This convenience is especially helpful in homes with multiple floors, where you might have to navigate down a staircase before the robot is able to get to the bottom. It also eliminates the requirement for a long cord, which means you can move furniture without worrying about your robot getting tangled up in the cord or running out of power while cleaning.

The app serves as an important control point for monitoring and scheduling tasks. The app allows you to modify the cleaning mode, power and the water level of your robotic cleaner. This feature is especially useful inside homes that have multiple floor types -- for example, carpet and tile because you can designate the robot to clean every room using the appropriate power and mode.

Certain models have an inbuilt camera that can send live feeds to the app. These models are great for pet owners and people with children who need to keep an eye on the robot as it functions. Other smart robots come with sensors that can detect when they've reached the edge of a room and then return to their base to dock. This prevents them from encroaching on an area and also ensures that they've cleaned all surfaces within your home.

Some models can automatically empty the dustbin and wash their mop heads and blow dry them between cleaning sessions. This eliminates the need for manual maintenance, and the robot cleaner will perform better for longer. There is also a model that has a longer battery life that helps you avoid the hassle of mid-cleaning recharges.

Sensors

Many robot vacuums are equipped with sensors that let them navigate around your home. They can be used on area rugs, carpets and hard floors like tiles and wood. They're not an alternative to an actual upright or canister vacuum cleaner, but they provide excellent suction for dirt and dust. They are a wonderful method of keeping the floor free of dirt between deep cleanings with a traditional machine.

Sensors allow the robot to navigate around your home, detecting obstacles, and also avoiding falling down the stairs. They also let you create physical and virtual "no-go" zones using the feature known as boundary strips or virtual walls (like the ones employed by Eufy) to block the robot from entering certain areas of your home. Certain robots also come with cliff sensors, which warn you when the robot is close to running into an edge.

The type of navigational system the robot utilizes is determined by your budget and layout of your home. The most advanced robotic vacuums use LiDAR sensors to map and scan the area, ensuring accurate navigation. These systems can be costly but provide the most effective results. Models that are budget-friendly with basic navigation bumps are less precise and can miss some areas. They are great for avoiding major obstacles, but they can still be unable to detect dirt in crevices or around baseboards.

Select a model with a an enormous dust bin and long battery life. You can find models that dock and recharge and then pick up where they were when they left. This saves time. In addition to navigation and cleaning, you can get the most out of your robot broom vacuum by making sure you have everything ready for each cleaning session. Check that all power cords as well as toys and other debris is tucked out of the path of the robot and empty the trash bin after each cleaning. Cleanse the sensors and charging port to keep your robot healthy.

Navigation

The best robot cleaner robot vacuums use mapping technology to create a digital map of your home during the initial cleaning session. It assists them in recognizing the different textures of hard or carpeted floors and ensures that all areas are cleaned. It also prevents your robots from cleaning the same areas again to increase efficiency and decrease battery consumption. A majority of top models let you save maps to be used in the future. This is ideal for large homes.

The majority of robotic vacuums come with some form of obstacle avoidance that keeps them from crashing into cords, shoes, or socks. These sensors are not always able to detect small objects. Some time ago manufacturers began adding additional sensors to their robots, allowing them identify and avoid household items that traditional sensors could not. These include wall and cliff sensors, which function by bouncing light beams infrared off surfaces to determine distances.

Certain sensors are integrated directly into the robot base, however, others require being purchased separately. These sensors aid the robot to move safely, avoid falling on steps, and keep away from clutter. Certain models come with anti-drop sensors that automatically stop the robots from hitting furniture and walls.

LiDAR mapping the most advanced navigation system available is a feature that you should consider when buying a robot vacuum. It uses an ejector that spins on the robot to map your home. It can map your home's layout by bouncing infrared beams off your walls and furniture. This helps to plan efficient routes and also clean your entire house.
