What Makes a Robot Vacuum Cleaner Best?

The most effective robot vacuums feature a powerful engine and a robust set of bristles or rollers. They also have adequate dustbins and long battery life.

Some models map homes using smart mapping. They can stop to recharge, then clean up where they stopped. They can set up no-go zones, and determine the different surfaces.

Object Avoidance

Object detection is a crucial feature of robot vacuums since it allows them to avoid getting into small objects like shoes, socks, toys or cords that aren't in the floor but on furniture or other objects. These systems use an integrated camera to detect objects in an AI database, and instruct the vacuum to stay clear of them. The Eufy S1 Pro uses a combination of sensors, including 3D Time of Flight, which emits light pulses into the room to determine distance and the depth of objects, and 3D Structured Light, which beams a pattern of light onto the room, analyzing the light distortion, to create a map, to avoid obstacles.

A recent addition to the arsenal of obstacle avoidance is artificial intelligence and visual interpretation, which enables robots to recognize and comprehend what they're facing. This software uses one or two cameras to view the world around them and analyzes it in real time. This software is used by ECOVACS DEEBOT to detect up 30 different objects, including cables and shoes.

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

No matter which sensors or cameras are used, it is important that your robot has a long battery lifespan to be able to complete a home without having to return to the dock for recharge. Choose a model with an extended battery life of at least 80 minutes, or more, depending on the size and shape of your home.

Self-Emptying Bases

Certain robot vacuum cleaners come with self-emptying bases. This can reduce the frequency at which you must empty your bin. They're considered a premium feature that typically increases the cost of a robot.

The best inexpensive robot vacuum robots come with bases that can hold bins, or a movable dustbin. You can open it and empty it once full. This can cut down on the amount of time you spend thinking about when to empty your dustbin and can make a significant difference in the case of a messy household.

Self-emptying bases are found on all the robots we've reviewed in our review, with the exception of the basic Roomba I3+, which doesn't have a self-emptying base. That's a shame, because the robot is a very strong performer. It has the best robot vacuums mapping results of all the robots we tested and it has great navigation capabilities. It also has good mower power and docking stations which can automatically empty the water tank when it is required.

It doesn't have iRobot's advanced obstacle avoidance system and digital keep-out zones, but it can become tangled in cables and rugs, and is unable to see rogue shoelaces or socks. However, it's an excellent option for an apartment that is small and well-maintained.

Other strengths are its navigation system, which includes bump sensors as well as a drop sensor, and the ability to make your home a map with lasers and cameras. It's also simple to set up, has numerous settings and modes, and also offers excellent mowing and vacuuming performance. Another perk is its smart-home functionality, which allows it to work with voice commands using Amazon Alexa and Google Assistant. This can make it easier to use if have multiple tablets or smartphones and don't want to grab the remote vacuum.

App Controls

Some robots are Wi-Fi compatible that allow you to control them from your smartphone or tablet. This feature is particularly beneficial in large homes with multiple floors, where you might need to walk down a staircase before the robot is able to get to the bottom of it. It also removes the requirement for a long cord, which means you can move furniture around without having to worry about your robot getting tangled up in the cord or running out of power while cleaning.

The app functions as a central control point for monitoring and scheduling tasks. The app lets you modify your robotic vacuum cleaner reviews cleaner's power, cleaning modes and water level settings. This feature is particularly useful inside homes that have different flooring types -- for instance, carpet and tile because you can designate the robot to clean every room using the appropriate power and mode.

Some models come with a built-in video camera that transmits live video directly to the application. These models are perfect for pet owners as well as those with small children who want to watch the robot while it works. Smart robots also use sensors to know when they reach the edges of a space and return to their docking station. This prevents them from taking over an area and makes sure they have cleaned all surfaces within your home.

Some models can empty the dustbin automatically and even wash their mop heads and blow dry between cleaning sessions. This reduces the need for manual maintenance and keeps the cleaner in good working order for a longer time. You can also pick one with a longer battery lifespan that will allow you to avoid the hassles of recharging mid-cleaning.

Sensors

Many robot vacuums use sensors to navigate your home and work their magic on hard floors, such as laminate, tile, and wood as also low pile carpets and area rug. They're not a substitute to an upright or full-size canister cleaner, but provide superior suction and a fantastic way to keep your floor free of dust between deep cleanings.

Sensors allow the robot to navigate around your home, detecting obstacles, and avoiding falling on stairs. You can also set up physical and virtual "no go" zones by using boundary strips or virtual walls (like the ones employed by eufy) to prevent the robot entering specific areas within your home. Some robots come with cliff sensors that warn you when your robot is about to fall into the edge of a cliff.

The kind of navigational system the robot uses is determined by your budget and home layout. Some of the most advanced robotic vacuums employ LiDAR sensors to map and scan the area to ensure precise navigation. These systems can be costly but they deliver the most effective results. Budget-friendly models with rudimentary bump navigation systems are less precise and may miss certain spots. They're good for avoiding major obstacles, but they may still fail to spot dirt in crevices and around baseboards.

Look for a model with an extra-large dust container and an extended battery life. You can find models that dock and recharge, then resume where they stopped. This saves time. In addition to navigation and cleaning, you can get the most out of your robot vacuum by prepping for each cleaning session. Check that power cords as well as toys and other debris are kept away from the robot's path, and empty the bin after each cleaning. Wipe down the sensors and charging port to ensure your robot is in good health.

Navigation

The most effective robot vacuums employ mapping technology to create a digital map of your home during the initial cleaning session. It helps them recognize the different textures, like hard and carpeted floors, and ensures that all areas are clean. Mapping also prevents your robot from cleaning the same areas, which improves efficiency and may reduce battery consumption. Many top models come with the option of saving the map of your house to use in the future which is ideal for larger homes.

The majority of robotic vacuums come with some form of obstacle avoidance, which stops them from running into cords, shoes, or socks. However, these sensors can't always detect small objects. Manufacturers started adding sensors to robots around a year ago. They were able to identify and avoid objects that sensors could not. These include wall and cliff sensors, which work by bouncing light beams infrared off surfaces to calculate distances.

Certain sensors are integrated directly into the robot's base however, others require being purchased separately. These sensors assist the robot to navigate safely and avoid falling down 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 is the most recent and most advanced navigation technology, and it's an option to look for in the robot vacuum. This kind of system utilizes an ejector-type laser that is mounted on the top of the robot to map your home. It can map your home by bouncing infrared beams off your walls and furniture. This information can help it plan efficient paths and also clean your home.
