What Makes a Robot Vacuum Cleaner Best?

The most effective robot vac vacuums come with an engine that is powerful 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, and can pause to recharge, and Robot vac then resume cleaning where they have left off. They can also set up zones that are not allowed to enter, and can determine the different surfaces.

Object Avoidance

Object detection is a key feature for robot vacuums as it helps them avoid crashing into small objects such as cords, toys, socks, or shoes that aren't on the floor, but rather on furniture. These systems use cameras built into the system to identify objects that are listed in an AI database and then teach the vacuum to avoid them. The Eufy S1 Pro, for example, utilizes a mix of sensors, including 3D Time of Flight (sending light pulses to gauge the distance and depth of nearby objects) and 3D Structured Light (beaming a pattern of light onto the space and analyzing the light distortion to create a map) to ensure that it is clear of obstacles.

Artificial intelligence and visual interpretation are newer addition to robot obstacle avoidance. They enable robots to better understand and detect what they encounter. This software uses one or two cameras to see the world around them, and then analyzes it in real-time. The ECOVACS DEEBOT uses this software to detect up to 30 kinds of objects such as cables, shoes, and pet poop.

Certain models also use LiDAR to navigate. This technology emits laser beams and records the time it takes them to bounce back at the surrounding surfaces to create a real-time, 3-D map of the environment. This is useful for detecting walls, furniture and even stairs. It might not work in dim light or with transparent or reflective objects.

Whatever cameras or sensors are employed it is crucial that your robot has a long battery lifespan to be able to complete your home without having to return to the dock for recharging. Choose models that can run for at least an hour or more, depending on the size of your living area.

Bases that Self-Empty

Some robot vacuum cleaners feature self-emptying bases. This can decrease the frequency that you need empty your dustbin. They're considered a premium feature, and usually add to the price of a robot.

The most effective robots have bases that can either house either a bin or a dustbin that is easy to open and empty when full. This can help you save time by cutting down on the 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 pity because this robot is extremely efficient. It got the best mapping results of all the robots we tested and it has excellent navigating abilities. It also has excellent mowing power and a docking station which can automatically empty the water tank whenever it is required.

It doesn't come with iRobot's sophisticated obstacle avoidance or digital keep-out zones, though it can get tangled up on rugs and cables and can't see rogue socks and shoelaces. It's an excellent choice for a small home that's well-maintained.

Other strong points are its navigation system that includes bump sensors and a drop sensor, and its ability map out your whole house using cameras and lasers. It's also simple to set up, offers a wide variety of settings and modes, and provides an excellent performance in mowing and vacuuming. Another advantage is its smart-home connectivity that allows it to function with voice commands using Amazon Alexa and Google Assistant. This can make it easier to use in the event that you own multiple tablets or smartphones and don't want to purchase a traditional remote.

App Controls

Certain robots are able to connect to Wi-Fi, allowing users to control them from your tablet or smartphone. This feature is particularly beneficial in homes with a lot of floors, in which you may have to navigate your way through a staircase before the robot can come to the bottom of it. This removes the need for an additional long cord so you can move furniture with no worries about the robot getting caught in it or running out of power while cleaning.

The app acts as a one-stop control center to monitor and schedule tasks. The app lets you customize the power, cleaning mode and water level of your robotic cleaner. This feature is particularly useful inside homes that have multiple floor types -- for instance, carpet or tile because you can designate the robot vacuum cleaner quiet to clean every room with the appropriate power and mode.

Certain models come with a built-in video camera that can send live feeds directly to the app. These models are a great option for pet owners or people with young children who need to monitor the robot while it's in operation. Other smart robots have 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 taking over the space and makes sure that they've cleaned the surfaces of your home.

Certain models can empty the dustbin automatically and even wash their mop heads and blow dry between cleaning sessions. This will reduce the need for manual maintenance, and the robot cleaner will work better over a longer period of time. You can also choose a model with a longer battery life which allows you to avoid the hassle of having to recharge mid-cleaning.

Sensors

Many robot vacuums use sensors to navigate your home and work on hard floors, such as laminate, tile, and wood as also low pile carpets and area rugs. They're not an alternative to a full-size canister or upright cleaner, but offer excellent suction and a great method to keep your floor clean between deep cleanings.

Sensors assist the robot in navigating your space by finding obstacles and avoiding falling down stairs. They also let you define physical and virtual "no-go" zones by using a feature called boundary strips or virtual walls (like the ones used by Eufy) to stop the robot from entering certain areas of your home. Some robots have cliff sensors that alert you when your robot is about to fall into the edge of a cliff.

The type of navigation system the robot uses depends on your budget and home layout. Some of the most sophisticated robotic vacuums make use of LiDAR sensors to map and scan rooms, ensuring precise and efficient navigation. These systems are costly however they deliver the best budget robot vacuum results. Budget models with rudimentary navigation bumps are less precise and can miss some spots. They're great for avoiding big obstacles, but they may still miss dirt in crevices and around baseboards.

Choose a model that has an enormous dust bin and long battery life. There are models that recharge and then resume where they left off when they dock, which can save you time. In addition to navigation and cleaning, you can get the most expensive robot vacuum out of your robot vacuum by prepping for each cleaning session. Check that all power cables as well as toys and other debris is tucked out from the robot's path. Then empty the trash bin after each cleaning. Clean the sensors and charging port to ensure your robot is in good health.

Navigation

The top robot vacuums create a digital mapping of your home with mapping technology in the initial cleaning session. It assists them in recognizing the different the different textures, like hard and carpeted floors, and ensures that all areas are clean. It also prevents your robots from having to clean the same areas over and over again and can increase efficiency and decrease battery consumption. Many high-end models let you save the map to use in the future. This is perfect for homes with large spaces.

Most robotic vacuums come with an obstacle avoidance system that prevents them from slamming into cords or socks, or shoes. The sensors don't always detect small objects. In the past few years manufacturers began adding more sensors to their robots, allowing them to identify and avoid household items that conventional sensors couldn't. They include cliff sensors and wall sensors that function by reflecting infrared beams of light off surfaces to determine distances.

Certain sensors are built directly into the robot's base however, others require being purchased separately. These sensors generally aid the robot in navigating safely, avoid falling down steps and avoid clutter. Certain models come with anti-drop sensors that prevent the robots from crashing against furniture and walls.

LiDAR mapping the most advanced navigation system is a feature that you should look for when purchasing a robot vacuum. It uses a spinning sensor mounted on the robot to map your home. By bounced infrared beams off your walls and furniture it is able to determine the layout of your room. This information helps it plan efficient routes and also clean your entire house.
