What Makes a Robot Vacuum Cleaner Best?

The top robot vacuums come with a an efficient motor and a bristles or rollers that are durable. They also have large dustbins and a long battery life.

Certain models use smart mapping to create maps of homes. They can stop, recharge and then clean up right where they started. They can also set up zones that are not allowed to enter, and can recognize different surfaces.

Object Avoidance

Object detection is an essential feature of robot vacuums since it allows them to avoid running into small things like shoes, socks, toys or cords that aren't found on the floor but on furniture or other objects. The systems utilize an inbuilt camera to detect 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 that include 3D Time of Flight (sending light pulses to determine the distance and depth of the surrounding objects) and 3D Structured Light (beaming a pattern of lights onto the room and analyzing the distortion of light to create an image) to efficiently steer away from obstacles.

A recent addition to the arsenal of obstacle avoidance is artificial intelligence and visual interpretation, which enables robots to more easily identify and comprehend what they're facing. The software works with cameras that are either dual or single to observe the world around them and analyzes it in real time. This software is used by the ECOVACS DEEBOT to detect up 30 different objects, which includes cables and shoes.

Some models utilize LiDAR to navigate. This technology emits laser beams and records the time it takes them to bounce back at nearby surfaces to create a live, 3-D map of the surroundings. This is useful for detecting walls, furniture and even stairs. It might not be effective in dim light or with transparent or reflective objects.

Regardless of which sensor or cameras are being used, a good battery life is crucial to ensure that your robot is able to complete an entire home without having to return to its dock to recharge. Select a model that has an endurance of at least 80 minutes, or more, depending on the dimensions and layout of your home.

Self-Emptying Bases

Some robot vacuum cleaners feature self-emptying bases, which could decrease the frequency you must empty your bin. They're considered a premium feature that typically increases the cost of the robot.

The best robots have bases that can either hold a bin or a removable dustbin that you can easily open and empty when full. This can cut down on the amount of time you spend worrying about when you should empty your dustbin and can be a huge benefit when you have a busy household.

All the robots we reviewed have self-emptying bases, with the exception of the Roomba I3+. It's a pity, since this robot is otherwise a very strong performer. It had the best mapping results of all the robots that we tested, and also has superior navigational abilities. It also has excellent mower power and docking stations which can automatically empty the water tank whenever it is required.

It isn't equipped with iRobot's sophisticated obstacle avoidance technology and digital keep-out zones, but it is prone to getting caught in cables and rugs, and cannot see the stray shoelaces or socks. However, it's an excellent option for a small, well-maintained home.

Other strengths include its navigation technology that includes bump sensors as well as a drop sensor, and the ability to create a map of your entire home using cameras and lasers. It's also simple to set up, offers numerous settings and modes, and offers an excellent performance in mowing and vacuuming. Another benefit is its smart vacuum cleaner-home connectivity that allows it to function with voice commands via Amazon Alexa and Google Assistant. That can make it simpler to use if you have multiple tablets or smartphones and do not want to carry a remote control vacuum cleaner.

App Controls

Some robots can connect to Wi-Fi, which allows users to control them from your tablet or smartphone. This is particularly useful in homes with a lot of floors, where you might need to walk down a flight of stairs before the robot can come to the bottom. This removes the need for an additional 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 serves as central remote control vacuum cleaner point to monitor and schedule tasks. The app also lets you customize your robotic cleaner's power, cleaning mode and water level settings. This feature is especially useful in homes that have different flooring types, such as tiles and carpet. You can assign the robot the appropriate power and mode to clean each floor.

Some models come with a built-in video camera that sends a live feed directly to the app. These models are ideal for pet owners as well as those with small children who wish to watch the robot while it operates. Other smart robots come with sensors that recognize when they've reached the edges of a room, and return to their base to dock. This prevents them from taking over an area and makes sure they have cleaned all surfaces in your home.

Certain models automatically empty the dustbin and even wash and blow dries its mop heads between cleaning sessions. This reduces the necessity for manual maintenance and the robot cleaner will work better for a longer 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 utilize sensors to navigate your home and work their magic on hard floors like wood, tile and laminate as also low pile carpets and area rugs. They're not a replacement for the full-size upright or canister vacuum cleaner, but they provide excellent suction for dirt and dust. They are a wonderful way to keep the floor clean between deep cleanings with an upright machine.

Sensors allow the robot to navigate around your home, finding obstacles and avoiding falling off steps. They also allow you to create physical and virtual "no-go" zones by using boundaries or virtual walls (like the ones employed by Eufy) to block the robot from entering specific areas of your home. Certain robots have cliff sensors that alert you when your robot is about to fall into an obstacle.

The kind of navigation system that the robot uses depends on your budget and layout of your home. Some of the most sophisticated robotic vacuums make use of LiDAR sensors to map and scan rooms, which ensures accurate and efficient navigation. These systems are expensive, but they provide the most efficient results. Budget-friendly models with rudimentary bump navigation systems are less precise and may miss certain places. These models are good at avoidance of major obstacles, but they may fail to spot dirt in crevices and around baseboards.

Find a model that has an extra-large dust bin as well as a long battery life. There are models that can dock and recharge and then pick up where they stopped. This will save you time. You can make the most of your robot vacuum, as well as navigation, by prepping each cleaning session. Check that all power cords and toys are tucked away and away from the path of the robot, and empty the bin after each cleaning. Also, wipe down the charging ports and sensors to ensure that the robot is healthy.

Navigation

The most effective robot vacuums employ mapping technology to create digital maps of your home prior to the initial cleaning session. It allows them to recognize textures such as carpets or hard floors and ensures that all areas are cleaned. Mapping also saves your robot from re-cleaning the same areas that improves efficiency and reduces battery usage. Many high-end models have the option to save the map of your home to use in the future, which is great for larger homes.

The majority of robotic vacuums have an obstacle avoidance system that prevents them from slamming into cords or socks, or shoes. These sensors do not always detect smaller objects. A few years ago manufacturers began adding more sensors to their robots, which allowed them to detect and avoid household items that standard sensor systems couldn't. These include cliff sensors as well as wall sensors that work by reflecting infrared beams light off surfaces to calculate distances.

Some of these sensors are integrated into the robot's base, while others require an additional attachment. They generally aid the robot in navigating in a safe manner, avoid falling down steps and avoid clutter. Some models come with anti-drop sensors, which prevent the robot from hitting furniture and walls.

LiDAR mapping, the most advanced navigation system is a feature you should look for when purchasing the robot vacuum. It uses an ejector that spins on the robot to map out your home. It can map your home's interior by bounces of infrared rays off your walls and furniture. This helps to plan efficient routes and clean your entire house.
