What Makes a Robot Vacuum Cleaner Best?

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

Certain models use smart mapping to identify homes, and they can stop, recharge and then clean up right where they stopped. They can even set no-go zones and identify different surfaces.

Object Avoidance

Object detection is a key feature for robot vacuums as it helps them avoid crashing into small objects such as socks, toys, cords or shoes that aren't on the floor, but on furniture. The machines use an inbuilt camera to detect objects that are in an AI database and then instruct 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 measure the distance and depth of the surrounding objects) and 3D Structured Light (beaming a pattern of lights across the space and analyzing the distortion of light to create a map) 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. The software makes use of cameras that are either double or single to view the world and analyze it in real-time. This software is used by the ECOVACS DEEBOT to detect up 30 different objects, including shoes and cables.

Some models utilize LiDAR for navigation. The technology emits laser beams and measures the time it takes them to bounce back from nearby surfaces to create a live, 3-D map of the environment. This is useful for detecting walls, furniture and even stairs. However, it might not be as effective in dim lighting or when working with reflective or transparent objects.

Whatever cameras or sensors are employed it is crucial that your robot has a long-lasting battery so that it can last the duration of your home without having to return to the dock for recharging. Pick a model that has a battery life of at least 80 minutes or more depending on the dimensions and shape of your home.

Bases that self-eliminate

Some robot vacuum cleaners feature self-emptying bases, which can reduce the frequency you must empty your dustbin. They're considered to be a luxury feature, and usually add to the cost of the robot.

The best robots come with bases that can hold bins or a dust bin that is removable. It is possible to open it and empty it when full. This will save you time by reducing the amount of time you are occupied with deciding when to empty a dustbin.

All the robots we reviewed have self-emptying bases. The only exception is the Roomba I3+. This is a shame because the robot performs extremely well. It had the best mapping results of all the robots that we tested and has superb navigational capabilities. It also has a good mower power and a docking station that automatically empty the water tank when needed.

It's not equipped with iRobot's innovative obstacle avoidance technology or digital keep-out zones it is hung up on cables and rugs and doesn't have the ability to detect the stray socks or shoelaces. It's a great option for a small home that is well-maintained.

Other strengths include its aforementioned navigation technology, including bump sensors and drop sensors, and its ability to map out your entire home using cameras and laser. It is simple to use, comes with a variety of options and settings and is a great choice for mows or vacuuming. Another perk is its Smart robot-home connectivity, which enables it to work with voice commands using Amazon Alexa and Google Assistant. This can make it simpler to use if you have multiple smartphones or tablets and don't want to grab a remote.

App Controls

Some robots are Wi-Fi compatible which allows you to control them using your smartphone or tablet. This is particularly useful in large homes that have multiple floors. It is possible that you will need to navigate down a staircase to reach the robot before it is able to reach the bottom. This removes the need for an additional long cord so you can move furniture without worrying about the robot becoming tangled in it or running out of power while cleaning.

The app acts as a one-stop control center for monitoring and scheduling tasks. The app allows you to customize your robot cleaner's power, cleaning modes and levels of water. This feature is particularly useful in homes that have multiple flooring types, such as tiles and carpet. You can assign the robot the right power and cleaning mode to clean each area.

Some models have an integrated video camera that transmits live feeds directly to the application. These models are ideal for pet owners as well as those with small children who want to monitor the robot as it functions. Other smart robots have sensors that recognize when they've gotten to 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 every surface within your home.

Certain models can empty the dustbin automatically and wash their mop heads and blow dry them between cleaning sessions. This minimizes the frequency of manual maintenance and keeps the cleaner in good working order for a longer period of time. There is also a model that has a longer battery life, which helps you avoid the hassle of mid-cleaning recharges.

Sensors

A lot of robot vacuums are fitted with sensors that let them navigate through your home. They can be used on area rugs, carpets, and hard floors such as tile and wood. They're not a substitute to an upright or full-size canister cleaner, but they provide excellent suction and a great way to keep your floor clean between deep cleanings.

Sensors let the robot navigate around your home, finding obstacles and also avoiding falling down steps. You can also create virtual and physical "no go" zones by using boundary strips or a virtual wall (like those used by Eufy) to prevent the robot from entering certain areas within your home. Certain robots have cliff sensors which alert you when your robot is set to run into the edge of a cliff.

The type of navigation system the robot employs is contingent on your budget and layout of your home. Some of the most advanced robotic floor vacuums vacuums use LiDAR sensors to map and scan the area, ensuring accurate navigation. These systems are costly, but they deliver 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 effective in avoiding major obstacles but can fail to spot dirt in crevices and around baseboards.

Pick a model that has a large dust bin and long battery life. You can also find models that recharge and resume the same place they left off after they dock to help save time. You can make the most of your robot vacuum, in addition to navigation by preparing each cleaning session. Check that all power cords as well as toys and other debris is removed of the robot’s path and empty the bin after each cleaning. Clean the sensors and charging port to ensure that your robot is healthy.

Navigation

The best robot vacuum for large house robot vacuums use mapping technology to create a digital map of your home during the initial cleaning session. It allows them to recognize different textures, such as carpets and hard floors, and ensures that all areas are clean. Mapping also prevents your robot from having to clean the same spots that improves efficiency and reduces battery consumption. Many high-end models have the option to save the map of your house to be used in the future, which is great for larger homes.

The majority of robotic vacuums have some sort of obstacle avoidance system that prevents them from slamming into cords or socks or shoes. However, these sensors can't always detect smaller objects. A few years ago, manufacturers began adding additional sensors to their robots, allowing them to detect and avoid household objects that traditional sensors could not. These include cliff sensors as well as wall sensors that operate by reflecting infrared beams of light off surfaces to determine distances.

Some of these sensors are built into the robot's base, while others require you to purchase an additional attachment. They generally assist the robot to navigate without danger and avoid falling down steps and keep clear of clutter. Certain models have anti-drop sensors that prevent the robots from hitting furniture and walls.

LiDAR mapping is the latest and most advanced technology for navigation, and it's a feature that you should look for in the robot vacuum. This type of system uses a spinning laser sensor mounted on the top of the self-cleaning robot vacuums to map your home. By scattering infrared beams across furniture and walls, it can sense the layout of your space. This helps it plan efficient paths and clean your entire home.
