What Makes a Robot Vacuum Cleaner Best?

The most effective robot vacuums have an efficient engine and a durable set of bristles or rollers. They also have adequate dustbins and large battery life.

Certain models use smart mapping to create maps of homes. They can pause, recharge and resume cleaning right where they left off. They can also set up zones that are not allowed to enter, and can recognize different surfaces.

Object Avoidance

Object detection is a key feature for robot vacuums as it helps them avoid getting into small objects such as socks, toys, cords or shoes that are not on the floor, but rather on furniture. The systems utilize an integrated camera to detect objects in an AI database, and then teach the vacuum to avoid them. The Eufy S1 Pro, for example, uses a combination of sensors that include 3D Time of Flight (sending light pulses to gauge the distance and depth of nearby objects) and 3D Structured Light (beaming a pattern of lights across the room and then analyzing the light distortion to create an image) to effectively steer away from obstacles.

A new addition to the obstacle avoidance repertoire is artificial intelligence and visual interpretation, which allows robots to more easily identify and comprehend what they're facing. This software utilizes cameras that are either double or single to observe the world and analyze it in real-time. This software is used by ECOVACS DEEBOT to detect up 30 different objects, including cables and shoes.

Some models also use LiDAR to navigate. This technology emits lasers, and measures the time taken to bounce off surrounding surfaces in order to create a 3-D map. This is useful for detecting walls, furniture and even stairs. It might not be effective in low light or with reflective or transparent objects.

Regardless of which sensor or cameras are being used regardless of the camera or sensor, a long battery life is crucial to ensure that your robot will be able to complete an entire home without the need to return to its dock to recharge. Look for a model that can run for at least an hour or more, based on the dimensions of your living space.

Bases that self-eliminate

Some robot vacuum cleaners feature self-emptying bases. This can decrease the frequency that you need empty your dustbin. They are considered a premium and add to the cost of a robot vacuum cleaner.

The best robots come with bases that hold either bins or a removable dustbin. It is possible to open it and empty it when full. This can help you save time by decreasing the amount of time you spend worrying about the time to empty a bin.

Self-emptying bases are present on all the robots in our review, except for the basic Roomba I3+, which doesn't have a self-emptying base. It's a pity, since this robot is otherwise a very strong performer. It had the top mapping results of all the robots we tested and has excellent navigational capabilities. It also has good mower power, as well as docking station that automatically empty the water tank when required.

It doesn't have iRobot's advanced obstacle avoidance technology and digital keep-out zone, but it can become tangled in cables and rugs, and cannot see the stray shoelaces or socks. It's an excellent choice for a smaller home that is well-maintained.

Other highlights are its navigation technology, which includes bump sensors and a drop sensors, as well as its ability to map out your whole house by using lasers and cameras. It's also easy to set up, comes with a wide variety of settings and modes, and offers outstanding mowing and vacuuming performance. Its smart-home function allows it to be controlled via voice commands using Amazon Alexa or Google Assistant. This makes it easier to use if you have multiple tablets or smartphones and don't want to grab an additional remote.

App Controls

Some robots are Wi-Fi enabled which allows you to control them from your tablet or smartphone. This is especially useful in homes with multiple floors. You may need to navigate down a staircase to reach the robot before it can reach the bottom. It also eliminates the need for a lengthy cord, allowing you to move furniture around without having to worry about your robot getting caught up in the cord or running out of power while cleaning.

The app functions as a central control point to monitor and schedule tasks. The app also allows you to customize your robot broom cleaner's power, cleaning modes and levels of water. This feature is especially useful in homes with multiple floor types -- for example, carpet and tile -- because you can set the robot to clean each room with the correct power and mode.

Some models have a built-in camera that transmits a live feed to the app. These models are a good choice for pet owners or people with young children who wish to monitor the robot while it's working. Some smart robots also have sensors that detect when they've reached the edges of a room and then return to their base to dock. This prevents them from overrunning the area and also ensures that they've cleaned all of the surfaces in your home.

Certain models are able to automatically empty the dustbin and wash and blow dries its mop heads between cleaning sessions. This reduces the necessity for manual maintenance and the robot bot cleaner will perform better for longer. You can also choose a model with an extended battery which allows you to avoid the hassle of having to recharge mid-cleaning.

Sensors

Many robot vacuums make use of sensors to navigate around your home and work their magic on hard floors, such as laminate, tile, and wood as well as low pile carpets and area rugs. They're not an alternative to an upright or full-size canister cleaner, but offer excellent suction and are a great way to keep your floors free of dust between deep cleanings.

Sensors let the highest rated robot vacuum navigate through your home by detecting obstacles, and avoiding falling off steps. They also allow you to 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 come with cliff sensors that warn you when your robot is about to fall into an obstacle.

The type of navigation system the robot uses depends on your budget and home layout. Some of the most advanced robotic vacuums make use of LiDAR sensors to scan and map rooms, which ensures accurate and efficient navigation. These systems are expensive however they provide the most effective results. Budget-friendly models with rudimentary bump navigation systems aren't as precise and can miss places. These models are effective in getting around obstacles, but they can fail to spot dirt in crevices and around baseboards.

Select a model with a an enormous dust bin and long battery life. There are also models that recharge and then resume the same place they left off after they dock, which can save you time. You can make the most of your robot vacuum, in addition to navigation, by prepping each cleaning session. Make sure that all power cords, toys, and other debris is tucked out of the path of the robot broom and empty the bin after each clean. Also, clean the sensors and charging ports to keep the robot in good health.

Navigation

The most effective robot vacuums create a digital mapping of your home with mapping technology in the first automated cleaning session. It assists them in recognizing the different textures, such as hard floors and carpets, and ensures that all areas are thoroughly cleaned. The mapping also stops your robot from cleaning the same areas, which improves efficiency and reduces the use of batteries. Many top models come with the option of saving the map of your house to be used in the future which is a great feature for homes with larger spaces.

Most robotic vacuums feature some kind of obstacle avoidance, which prevents them from running into shoes, cords or socks. However, these sensors can't always detect smaller objects. A few years ago manufacturers began adding additional sensors to their robots, which allowed 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 light off surfaces to calculate distances.

Certain sensors are built directly into the robot base, while others need to be purchased separately. These sensors help the robot navigate in a safe manner and avoid falling off stairs, and stay away from clutter. Certain models come with anti-drop sensors that automatically stop the robots from hitting furniture and walls.

LiDAR mapping, the most advanced navigation system available is a feature that you should look for when buying robot vacuum. This kind of system utilizes the spinning laser sensor that is placed on the top of the robot to map your home. By scattering infrared beams across furniture and walls it is able to determine the layout of your room. This information helps it plan efficient routes and also clean your entire house.
