What Makes a Robot Vacuum Cleaner Best?

The top robot vacuums come with an efficient engine and a robust set of bristles or rollers. They also come with large dustbins and a long battery life.

Certain models map homes with smart mapping, and can stop to recharge, and then clean up where they stopped. They can also set up no-go zones, and determine the 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 socks, toys, cords, or shoes that are not on the floor, but instead on furniture. These systems use a built-in camera to recognize objects that are listed in an AI database and then instruct the vacuum how to avoid them. The Eufy S1 Pro uses a combination of sensors, including 3D Time of Flight, which emits light pulses into the room to measure distance and the depth of objects, and 3D Structured Light, which beams a pattern onto the room, analyzing the distortion of light to build a map to steer clear of obstacles.

Artificial intelligence and visual interpretation are a more recent addition to robot obstacle avoidance. They enable robots to better comprehend and detect what they encounter. This software uses one or two cameras to view the world around them and then analyzes it in real-time. This software is used by ECOVACS DEEBOT to detect up 30 different objects, including shoes and cables.

Certain models also use LiDAR to navigate. This technology emits lasers and analyzes the time it takes for them to bounce off surfaces in order to create an 3D map. This is helpful in detecting walls, furniture and even stairs. However, it might not work as well in low lighting or with reflective or transparent objects.

No matter which cameras or sensors are employed it is crucial that your robot has a long battery life to be able to complete an entire home without needing to return to the dock for recharging. Look for an option that runs for at least 80 minutes or more, based on the size of your living area.

Self-Emptying Bases

Certain robot vacuum cleaners have self-emptying bases, which can reduce the frequency you must empty your dustbin. They are considered premium and add to the cost of a robotic vacuum cleaner.

The best robots come with bases that are able to hold either a bin, or a movable dustbin. You can open it and empty it when full. This can help you save time by decreasing the amount of time spent worrying about the time to empty a bin.

Self-emptying bases are found on all the robots featured in our review, except for the basic Roomba I3+, which doesn't have one. This is a shame, as this robot is otherwise extremely efficient. It had the best combo vacuum mapping results of all the robots that we tested and has excellent navigational capabilities. It has a good mowing ability and a docking system that can empty the water tank on its own when it is needed.

It isn't equipped with iRobot's sophisticated obstacle avoidance technology and digital keep-out zone, but it can get tangled up in rugs and cables, and is unable to see rogue shoelaces or socks. It's an excellent choice for a small home which is well-maintained.

Other strengths include its aforementioned navigation technology, including bump sensors and drop sensors, as well as its ability to map your entire house using cameras and laser. It is easy to use, has many options and settings that are effective when mows or vacuuming. Its smart-home functionality allows it to be controlled with voice commands made using Amazon Alexa or Google Assistant. That can make it simpler to use if you have multiple tablets or smartphones and don't want to pick up an additional Remote Control vacuum Cleaner.

App Controls

Certain robots are able to connect to Wi-Fi, allowing users to control them from your tablet or smartphone. This is particularly useful in homes with a lot of floors, where you may need to walk through a staircase before the robot can come to the bottom of it. It also eliminates the need for a lengthy cord, so you can move furniture freely without having to worry about your robot getting caught in the cord or running out of power while automated cleaning.

The app acts as a one-stop control center for monitoring and scheduling tasks. The app allows you to modify the power, cleaning mode and water level of your robotic cleaner. This feature is especially useful inside homes that have different flooring types -- for instance, carpet and tile because you can set the robot to clean each room using the appropriate power and mode.

Some models come with a built-in camera that transmits live feeds directly to the application. These models are ideal for pet owners and people with small children who want to monitor the robot as it works. Some smart robots also have sensors that detect when they've gotten to the edge of a room. They then return to their base to dock. This prevents them from taking over the space and makes sure that they've cleaned the surfaces of your home.

Some models can empty the dustbin automatically and wash their mop heads and blow dry between cleaning sessions. This reduces the requirement for manual maintenance and the robot cleaner will perform better for longer. You can also find a model that has an extended battery that helps you avoid the hassle of mid-cleaning recharges.

Sensors

A lot of robot vacuums are fitted with sensors that allow them to navigate around your home. They can work on area rugs, carpets, and hard floors such as tiles and wood. They're not a substitute to an upright or full-size canister cleaner, but provide superior suction and are a great method to keep your automatic floor cleaning machine clean in between deep cleanings.

Sensors assist the robot in navigating your space by spotting obstacles and avoiding falling down stairs. You can also set up physical and virtual "no go" zones by using boundary strips or virtual wall (like the ones used by Eufy), to prevent the robot entering specific areas within your home. Some robots come with cliff sensors that alert you when your robot is about to run into the edge of a cliff.

The kind of navigation system that the robot employs is contingent on your budget and layout of your home. The most advanced robotic vacuums use LiDAR sensors to map and scan areas that ensure accurate navigation. These systems can be costly however they provide the most effective results. The budget-friendly models that have basic bump navigation systems are less precise and could miss some areas. These models are adept at avoidance of major obstacles, but they may fail to spot dirt in crevices and around baseboards.

Choose a model that has a large dust bin and long battery life. There are models that can recharge and resume where they left off after they dock to help save time. You can make the most of your robot vacuum in addition to navigation, by prepping each cleaning session. Make sure that power cords as well as toys and other debris are kept out of the robot's path. Also, empty the bin between each cleaning. Clean the charging port and sensors to ensure your robot is in good health.

Navigation

The most effective robot vacuums employ mapping technology to create an electronic map of your home prior to the initial cleaning session. It helps them recognize textures, such as hard and carpeted floors and ensures that all areas are thoroughly cleaned. It also stops your robots from having to clean the same areas again, which can improve efficiency and reduce the amount of battery used. Many high-end models have the option to save the map of your house to be used in the future which is a great feature for homes with larger spaces.

Most robotic vacuum cleaner best vacuums feature some kind of obstacle avoidance that stops them from running into cords, shoes, or socks. However, these sensors can't always detect small objects. Manufacturers added sensors to robots in the past few years. This enabled them to identify and avoid objects that traditional sensors could not. These include wall and cliff sensors, which function by bouncing infrared light beams off of surfaces to determine distances.

Certain sensors are integrated directly into the robot's base, however, others require being purchased separately. In general, these sensors help the robot navigate in a safe manner, avoid falling down steps, and stay clear of clutter. Some models have anti-drop sensors, which will stop the robot from hitting furniture or walls.

LiDAR mapping, the most advanced navigation system available, is a feature you should look for when buying robot vacuum. This kind of system makes use of an ejector-type laser that is mounted on top of the robot to map your home. By bounced infrared beams off furniture and walls it is able to determine the layout of your room. This helps it plan efficient paths and also clean your home.
