What Makes a Robot Vacuum Cleaner Best?

The best robot vacuums feature an efficient engine and a sturdy set of bristles or rollers. They also have adequate dustbins and large battery life.

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

Object Avoidance

Object detection is a key feature for robot vacuums, since it allows them avoid crashing into small items like socks, toys, cords, or shoes that are not on the floor, but rather on furniture. The machines use a built-in camera to recognize objects that are listed 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 measure the distance and depth of the surrounding objects) and 3D Structured Light (beaming a pattern of lights onto the space and analyzing the light distortion to create a map) to ensure that it is away from obstacles.

Artificial intelligence and visual interpretation are more recent addition to robot obstacle avoidance. They enable robots to better comprehend and recognize what they come across. The software works with cameras that are either dual or single to view the world around them, and then 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 also use LiDAR to navigate. This technology emits laser beams and measures the time it takes them to bounce back at nearby surfaces to create a live 3-D map of the environment. This can be used to detect walls, furniture, and even stairs. However, it may not work as well in low lighting or with transparent or reflective objects.

Regardless of which 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 needing to return to its dock to recharge. Choose models that can run for at least 80 minutes or more, based on the size of your living space.

Bases that self-eliminate

Certain robot vacuum cleaners have self-emptying bases, which could reduce the frequency you need to empty your dustbin. They're considered to be a luxury feature that typically increases the overall price of a robot.

The best robots come with bases that can either house either a bin or a dust bin that you can open and empty when it's full. This will save you time by reducing the amount of time spent worrying about when to empty a dustbin.

All the robots we reviewed have self-emptying bases, except the Roomba I3+. This is a shame since this robot performs very well. It had the best inexpensive robot vacuum mapping results of all the robots we tested and it has excellent navigation abilities. It has a good mower, and it has a docking system that allows you to empty the water tank automatically when it is required.

It's not equipped with iRobot's innovative obstacle avoidance or digital keep-out zones, and it gets hung over cables and rugs and is unable to see rogue socks and shoelaces. It's a great option for a smaller home that is well-maintained.

Other strong points are its navigation system that includes bump sensors and a drop sensor, and the ability to map out your whole house using cameras and lasers. It is easy to use, comes with a variety of settings and modes and is a great choice for cleaning or mowing. Its smart-home feature allows it to be controlled via voice commands using Amazon Alexa or Google Assistant. This makes it easier to use if have multiple tablets or smartphones and don't want to pick up a remote.

App Controls

Some robots are Wi-Fi enabled which allows users to control them from your tablet or smartphone. This convenience is especially helpful in large homes with multiple floors, where you might have to navigate your way down a flight of stairs before the robot can come to the bottom of it. This eliminates the need for an extra long cord, allowing you to move your furniture without worrying about the robot getting tangled in it or running out of power when cleaning.

The app is a central control point to monitor and schedule tasks. The app lets you modify the cleaning mode, power and the water level of your robot cleaner. This feature is especially useful in homes with various flooring types, such as tiles and carpet. You can assign the robot the appropriate power and cleaning mode to clean each area.

Certain models come with an integrated video camera that sends live feeds directly to the app. These models are perfect for pet owners and those with children who need to watch the robot while it operates. Some smart robots utilize sensors to know when they are near the edges of a space, and then return to their docking station. This prevents them from overrunning the space and makes sure that they've cleaned all of the surfaces within your home.

Some models can empty the dustbin automatically and wash their mop heads and blow dry them between cleaning sessions. This eliminates the need for manual maintenance, and the robot cleaner will work better for longer. You can also choose an option with a longer battery lifespan which will help you avoid the hassles of mid-cleaning recharging.

Sensors

Many robot vacuums use sensors to navigate around your home and work on hard floors, such as wood, tile and laminate as also low pile carpets and area rug. They're not a replacement for the 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 free of dirt between deep cleanings with a traditional machine.

Sensors allow the robot to navigate around your home by detecting obstacles and also avoiding falling down steps. You can also create virtual and physical "no go" zones using boundary strips or a virtual walls (like those used by Eufy) to stop the robot entering specific areas in your home. Some robots also come with cliff sensors, which warn you when the robot is getting close to crashing into an edge.

The type of navigation system the robot utilizes will depend on your budget and the layout of your home. Some of the most advanced robotic vacuums utilize LiDAR-based sensors to map and scan rooms, ensuring precise and efficient navigation. These systems are expensive however they provide the best self cleaning robot vacuum results. Budget-friendly models with rudimentary bump navigation systems are less precise and could miss some places. They are great for avoiding major obstacles, but they may still fail to spot dirt in crevices and around baseboards.

Choose a model with an extra-large dust container and an extended battery life. You can find models that dock and recharge, then resume where they were when they left. This can save time. In addition to navigation and cleaning, you can make the most of your robot vacuum by prepping for each cleaning session. Check that all power cables, toys, and other junk is cleared from the robot's path. Then empty the trash bin after each cleaning. Also, clean the charging ports and sensors to keep the robot in good health.

Navigation

The most effective robot vacuums can create a digital map of your home using mapping technology in the initial cleaning session. It assists them in recognizing the different patterns, like carpets and hard floors and ensures that all areas are clean. It also stops your robots from having to clean the same areas repeatedly to increase efficiency and reduce the amount of battery used. A majority of top models let you save a map to be used in the future. This is perfect for large homes.

Most robotic vacuum cleaner on sale vacuums feature some form of obstacle avoidance, which keeps them from crashing into shoes, cords, or socks. However, these sensors do not always detect small objects. A few years ago, manufacturers began adding additional sensors to their robots, allowing them to identify and avoid household items that traditional sensors could not. These include cliff sensors and wall sensors that function 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. In general, these sensors assist the robot to navigate safely and prevent falling down stairs and avoid clutter. Certain models come with anti-drop sensors that automatically stop the robots from crashing against furniture and walls.

LiDAR mapping, the most advanced navigation system is a feature you should consider when purchasing the robot intelligent vacuum cleaner. This kind of system makes use of an ejector-type laser that is mounted on top of the robot to map your home. By bouncing infrared beams off of furniture and walls it is able to determine the layout of your home. This helps to plan efficient routes and also clean your entire house.
