What Makes a Robot Vacuum Cleaner Best?

The top robot vacuums have an engine that is powerful and a durable set of bristles or rollers. They also come with large dustbins and a long battery life.

Certain models map homes using smart mapping, and can pause to recharge, and then clean up where they left off. They can create no-go zones, and identify different surfaces.

Object Avoidance

Object detection is an essential feature for robot vacuums because it allows them to avoid hitting small objects such as socks, shoes, toys or cords that aren't on the floor, but instead on furniture or other items. These systems use a built-in camera to recognize objects that appear in an AI database and then teach the vacuum 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 the distance and the depth of objects, and 3D Structured Light, which beams a pattern of light onto the room and analyzes the light distortion 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 identify what they encounter. This software utilizes cameras that are either double or single to view the world and analyze it in real time. This software is used by ECOVACS DEEBOT to detect up 30 different objects, which includes cables and shoes.

Some models also use LiDAR to navigate. The technology emits laser beams and records the time it takes them to bounce back from surrounding surfaces to create a live, 3-D map of the environment. This is able to detect walls, furniture and even stairs. However, it may not work in dim lighting or with transparent or reflective objects.

No matter what sensors or cameras are utilized regardless of the camera or sensor, a long battery life is essential to ensure that your robot is able to complete the entire house without needing to return to its dock to recharge. Look for a model that can run for at least 80 minutes or more, based on the size of your living area.

Bases that self-eliminate

Some robot automated vacuum cleaner cleaners feature self-emptying bases. This could reduce the frequency that you have to empty your trash. They're considered to be a luxury feature and typically add to the price of the robot.

The best robots come with bases that are able to hold either bins, or a movable dustbin. You can open the bin and empty it when full. This will reduce the amount of time you spend worrying about when you should empty your bin and could make a big difference if you have a high-mess household.

All of the robots we tested have self-emptying bases, except the Roomba I3+. It's a pity, since the robot is extremely efficient. It has the best mapping results of all the robots that we tested, and it has excellent navigating abilities. It also has good mowing power and docking stations which can automatically empty the water tank whenever it is required.

It doesn't have iRobot's advanced obstacle avoidance technology or digital keep-out zones, and it gets hung up on cables and rugs and is unable to see rogue socks and shoelaces. It's a great option for a smaller home which is well-maintained.

Other highlights are its navigation system that includes bump sensors and drop sensor, and the ability to create a map of your entire home by using lasers and cameras. It is simple to use, comes with a variety of settings and modes, and performs well when mowing or vacuuming. Its smart-home functionality allows it to be controlled via voice commands using Amazon Alexa or Google Assistant. That can make it easier to use if have multiple smartphones or tablets and do not want to carry a remote.

App Controls

Some robots connect to Wi-Fi, allowing users to control them from your smartphone or tablet. This feature is particularly beneficial in homes with multiple floors, in which you may have to navigate through a staircase before the robot is able to get to the bottom. This removes the need for an extra long cord so you can move your furniture without worrying about the robot getting caught in it or running out of power while cleaning.

The app functions as a central control point to monitor and schedule tasks. The app allows you to alter the power, cleaning mode and water level of your robot cleaner. This feature is particularly beneficial in homes with multiple floor types -- for example, carpet and tile, as you can assign the robot to clean each room with the appropriate power and mode.

Some models come with a built-in video camera that sends live feeds directly to the app. These models are ideal for pet owners as well as those with small children who want to watch the robot while it functions. Some smart robots utilize sensors to know when they are near the edges of an area and return to their docking station. This prevents them from encroaching on an area and ensures they have cleaned all surfaces in your home.

Some models can empty the dustbin on their own and even wash their mop heads and blow dry them between cleaning sessions. This eliminates the necessity for manual maintenance and the robot cleaner will work better for a longer time. You can also pick a model that has a longer battery life which will help you avoid the hassles of recharging mid-cleaning.

Sensors

Many robot vacuums come with sensors that allow them to navigate around your home. They can work on area rugs, carpets as well as hard floors like tiles and wood. They're not an alternative to an upright or full-size cleaner, but provide superior suction and a fantastic way to keep your floor free of dust between deep cleanings.

Sensors let the robot navigate around your home by detecting obstacles and avoiding falling off the stairs. You can also set up physical and virtual "no go" zones using boundary strips or a virtual walls (like the ones employed by eufy) to stop the robot from entering certain areas in your home. Some robots have cliff sensors which alert you when your robot floor cleaner is about to fall into a cliff.

The type of navigation system the robot utilizes will depend on your budget and layout of your home. Some of the most advanced robotic vacuum cleaner reviews vacuums employ LiDAR sensors to map and scan the area that ensure accurate navigation. These systems are expensive but they deliver the most efficient results. Budget models with rudimentary navigation bumps aren't as precise and could miss certain places. These models are adept at getting around obstacles, but they can be unable to detect dirt in crevices or around baseboards.

Choose a model that has a large dust bin and long battery life. There are models that dock and recharge and then pick up where they left off. This saves time. You can get the most value from your robot vacuum, as well as navigation, by preparing each cleaning session. Make sure that all power cords as well as toys and other debris are kept out of the robot's path, and empty the bin between each cleaning. Clean the charging port and sensors to keep your robot healthy.

Navigation

The most effective robot vacuums can create a digital map of your home's interior using mapping technology in the first cleaning session. It assists them in recognizing the different textures of carpets or hard floors, and ensures that all areas are cleaned. It also prevents your robots from having to clean the same areas repeatedly, which can improve efficiency and decrease battery consumption. Many high-end models let you save maps to use in the future. This is perfect for large homes.

Most robotic vacuums feature some form of obstacle avoidance, which keeps them from crashing into shoes, cords or socks. However, these sensors can't always detect smaller objects. Manufacturers started adding sensors to robots a few years ago. This allowed them to recognize and avoid household objects that sensors could not. These include cliff sensors as well as wall sensors that operate by reflecting infrared beams light off surfaces to determine distances.

Some of these sensors are built into the robot's base while others require you to purchase a separate attachment. They generally help the robot navigate in a safe manner and prevent falling down steps and keep clear of clutter. Certain models come with anti-drop sensors which prevent the robot from colliding with furniture and walls.

LiDAR mapping the most advanced navigation system available is a feature you should look for when buying the robot vacuum. It uses an ejector that spins on the robot to map out your home. By scattering infrared beams across your walls and furniture it can determine the layout of your home. This information can help to plan efficient routes and clear your entire house.
