What Makes a Robot Vacuum Cleaner Best?

The best robot vacuums are equipped with an efficient motor and a set of bristles or rollers that are durable. They also have adequate dustbins and large battery life.

Some models map homes using smart mapping. They can pause to recharge, and then resume cleaning where they have left off. They can also set no-go zones and identify different surfaces.

Object Avoidance

Object detection is a crucial feature of robot vacuums, since it allows them to avoid running into small objects like socks, toys, cords or shoes that aren't on the floor, but rather on furniture. These systems employ an integrated camera to detect objects in an AI database, and instruct the vacuum to stay clear of 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 nearby objects) and 3D Structured Light (beaming a pattern of lights across the room and then analyzing the distortion of light to create a map) to effectively steer away from obstacles.

A recent addition to the arsenal of obstacle avoidance is artificial intelligence and visual interpretation, which allows robots to recognize and understand what they're encountering. This software utilizes two cameras to observe the world and analyze it in real-time. The ECOVACS DEEBOT uses this software to detect up to 30 types of objects, including shoes, cables and pet poop.

Some models also use LiDAR to navigate. This 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 useful in the detection of furniture, walls and even stairs. It might not work in dim light or with reflective or transparent objects.

No matter what sensors or cameras are used regardless of the camera or sensor, a long battery life is important to ensure that your robot can complete the entire house 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 size and shape of your home.

Self-Emptying Bases

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

The best robots come with bases that hold either a bin, or a dust bin that is removable. You can open the bin and empty it when it is full. This can reduce the amount of time that you spend worrying about when to empty your trash bin and can make a significant difference if you have a high-mess household.

Self-emptying bases are present on all the robots in our review, except for the bare-bones Roomba I3+, which does not have one. This is a shame, as the robot is a very strong performer. It had the highest mapping performance of all the robots we tested, and it has superb navigation abilities. It has a good mower and docking system that will empty the water tank on its own when it is required.

It doesn't come with iRobot's sophisticated obstacle avoidance or digital keep-out zones it is hung up on cables and rugs and is unable to see shoes and socks that aren't in order. It's a great option for a smaller home which is well-maintained.

Other highlights are its navigation technology, which includes bump sensors and drop sensor, and its ability create a map of your entire home by using lasers and cameras. It's also easy to set up, offers many settings and modes, and offers excellent mowing and vacuuming performance. Another benefit is its smart-home connectivity, which allows it to work with voice commands via Amazon Alexa and Google Assistant. This makes it easier to use if you own several tablets or smartphones, and don't want to buy a traditional remote.

App Controls

Certain robots are able to connect to Wi-Fi, which allows you to control them using your smartphone or tablet. This is particularly useful in homes with a lot of floors, where you may need to walk down a staircase before the robot is able to get to the bottom of it. This will eliminate the need for an additional long cord to move furniture without worrying about the robot getting tangled in it or running out power when cleaning.

The app serves as a central control point for monitoring and scheduling tasks. The app allows you to alter the power, cleaning mode and the water level of your robotic vacuum cleaner comparison cleaner. This feature is especially useful in homes with different flooring types -- for instance, carpet and tile -- because you can set the robot to clean smart robot every room with the appropriate power and mode.

Some models come with a built-in video camera that sends live video directly to the app. These models are a great choice for pet owners and those with children who want to keep an eye on the robot as it works. Other smart robots come with sensors that recognize when they've reached the edges of a room and then return to their base to dock. This prevents them from encroaching on an area and ensures they've cleaned every surface within your home.

Certain models can empty the dustbin automatically and even wash their mop heads and blow dry them between cleaning sessions. This will reduce the necessity for manual maintenance and the robot cleaner will function better for a longer time. There is also a model with an extended battery duration that helps you avoid the hassle of having to recharge mid-cleaning.

Sensors

Many robot vacuums come with sensors that allow them to navigate around your home. They can be used on carpets, area rugs and hard floors like tile and wood. They're not an alternative to an actual canister or upright vacuum cleaner, but they offer great suction on dirt and dust and are a fantastic method of keeping the floor clean between deep cleanings with a traditional machine.

Sensors help the robot navigate your home by spotting obstacles and avoiding falling down stairs. They also let you set virtual and physical "no-go" zones with boundaries or virtual walls (like the ones used by Eufy) to block the robot from entering certain areas of your home. Certain robots also come with cliff sensors, which warn you when the robot is getting close to crossing an edge.

The kind of navigation system that the robot utilizes will depend on your budget and the layout of your home. The most advanced robotic vacuums employ LiDAR sensors to map and scan the area, ensuring accurate navigation. These systems can be costly but they deliver the most efficient results. Budget-friendly models with rudimentary bump navigation systems aren't as precise and can miss spots. They're great for avoiding big obstacles, but they may still be unable to detect dirt in crevices or around baseboards.

Choose a model with an extra-large dust bin and a long battery lifespan. You can find models that can dock and recharge and then pick up where they were when they left. This can save time. You can maximize the use of your robot vacuum, in addition to navigation, by prepping each cleaning session. Make sure that power cords and toys are kept out of the robot's path, and empty the bin after each cleaning. Also, wipe down the sensors and charging ports to ensure that the robot is healthy.

Navigation

The most effective robot vacuums create digital maps of your home using mapping technology in the initial cleaning session. It allows them to recognize different patterns, like carpets and hard floors and ensures that all areas are cleaned. Mapping also saves your robot from re-cleaning the same spots, which improves efficiency and can reduce the use of batteries. Many top robot vacuum cleaner models come with the option to save the map of your house for future use, which is great for larger homes.

The majority of robotic vacuums come with some form of obstacle avoidance that prevents them from running into shoes, cords or socks. These sensors do not always detect smaller items. In the past few years manufacturers began adding additional sensors to their robots, allowing them to detect and avoid household objects that standard sensor systems couldn't. These include cliff sensors and wall sensors that function by reflecting infrared beams of light off surfaces to calculate distances.

Certain sensors are built directly into the robot's base, while others need to be purchased separately. They generally aid the robot in navigating in a safe manner and prevent falling down steps and keep clear of clutter. Some models even include anti-drop sensors that will stop the robot from crashing into furniture and walls.

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