The Best Robot Vacuums

A robot vacuum is a fantastic option to keep your floors spotless, whether you live in a 3,000 square foot home with three dogs or have a chic apartment. The best models come with self-emptying bases, docks and charge automatically. They also come with features like cliff sensors.

If carpeting is present, you should choose the vacuum cleaner that has a high suction power (measured in Pascals). Virtual barriers and no-go zones permit you to define areas the robot shouldn't enter.

Smart Mapping


Many robot vacuums don't come with the ability to map. This can be a problem if you are trying to get your home clean. These budget-friendly vacuums may get stuck on a wide variety of obstacles, such as cords, furniture legs and pet toys that have appeared from under sofa cushions.

This is why the most effective robot vacuums with obstacle avoidance employ multiple sensors and cameras to create a detailed map of the area they are moving through your home. This lets them navigate your rooms more efficiently, regularly cleaning in a systematic pattern, and not looking at areas that they have already cleaned. It also stops them from getting stuck on items that were moved during a cleaning process or having to spend time "robot-proofing" your home by putting cords out of their way.

Robot vacuums can utilize various methods of navigation to create maps, ranging from the simplest to the latest. Some models with budget prices make use of infrared sensors, whereas others use optical sensors that measure the time it takes for a signal reflected to reach the robot's backside. This allows the robot to determine its location within the room. Certain high-end robots, such as the eufy S1 Pro, have a feature known as SLAM navigation, which makes use of sensors in combination to create a map as it moves through the space.

This approach is the most advanced since it allows the robot to navigate more efficiently, but also provides a useful interface for the user. These systems display a 3D model with which you can interact, and can also create virtual boundaries or restricted zones for the robot. This type of mapping works even in darkness provided you have a source of light nearby (like lamps) which can light up a room enough for the robot to see its surroundings.

The latest robots are able to create a detailed map as they travel through your home with LiDAR or laser scanning. It's not as accurate as SLAM, but it is still useful for the purpose of avoiding obstacles. LiDAR is triggered by objects that absorb or reflect the laser beam. For example dark-colored floors will trigger the cliff sensors of most robots, causing them to stop.

Self-Emptying Bins

One of the most appealing features of robot vacuums is their capability to transfer debris automatically from their onboard dustbins to their docking bases, without any user intervention. This removes the requirement for the user to bend down to empty their bins, which decreases the frequency at which maintenance tasks are performed. This is particularly important if you have a large home and want to reduce the amount of time your hands are occupied with dust and dirt.

However, a fully empty robot can still take up to 7 hours to fully recharge and then resume cleaning, which may not be a good choice for large or families with a lot of activity. To prevent this from happening many manufacturers offer the option of pause and resume cleaning from where the robot left off after its battery has been recharged. This feature is available on the majority of robots and is a great addition if you often have to leave your home for work or parents of children who are young.

Check if the robot has a bag to collect debris or if it does not. A bagged model will ensure that dust doesn't release that has clumped up into the air when it's empty, but you'll need to purchase and replace the bags frequently. If you'd prefer a bagless model, search for models that have a smart sensor to check the dust bin and inform you when it's time to empty it.

The best robotic cleaners have docking sensors and cliff sensors as well as self-emptying bins to keep them from getting stuck or falling over obstacles. They can also use advanced AI to enhance efficiency and avoid various types of debris.

Most robot vacuums require regular maintenance and care in order to keep them running smoothly. This includes regular cleaning of the brushroll, sides brushes and wheels to remove pet hair and other debris that can clog them and affect suction power. You should also monitor the robot's battery level regularly to ensure that it's always charged to its full capacity. Batteries that are not fully charged or full will slow the robot down and cause it to perform less effectively. Therefore, it is important to monitor its charge regularly.

In our tests, some robots were exceptionally adept at getting pet hair out. This included the Roomba Combo 10 Max as well as the SwitchBot. Some robots were better than others at picking up hair from pets. Often these cheaper models rely on bump sensors for obstruction avoidance and can plow into things like hanging cords and shoelaces (see below). A few of the more expensive vacuum-and-mop robots we have tested employ advanced technology for smart mapping and learning to assist them in mapping your home and navigate better over time. This feature is especially useful for those with carpeted flooring and a lot pet hair.

To get the most benefit from these benefits it's recommended to perform some regular maintenance. This can include emptying the dust bin as well as cleaning the filters and other nooks and crannies from time to time and wiping down sensors for charging and anti-drop. Update the firmware to ensure that your robot will continue to function efficiently.

If you have a robot that has the ability to mop, make sure you clean the brush and wipe it off every now and then. It's important to keep it well-maintained and clean. Replace the mop pads every six months to ensure that they remain effective.

Some of the most advanced robots are able to create walls around your home when they're cleaning and preventing them from going into areas that you don't want them to enter. Using your smartphone, you can set up these virtual walls or boundary strips. This is particularly useful for those with hanging cords, wires and other items you don't want your robot to get stuck on or come into contact with. If you enable the feature within the app, certain robots will notify you when they're about to hit something. This is not a feature all robots provide however it's a good addition to the list.

Remote Control

Robotic vacuum cleaners are operated remotely and controlled by apps, voice commands, or traditional remotes. They also come with auto-charging and scheduling functions, which allow you to keep an orderly home without manual interaction. This feature is ideal for those with weak muscles and mobility, as they don't have to lift heavy furniture to access awkward spaces.

The top robotic vacuums are built to deal with a variety flooring surfaces and obstacles, adapting their operation to fit. They typically have smart sensors that recognize different areas of the room and adjust in accordance with the area. This feature lets a robot automatically switch between cleaning methods while switching from tile, carpet, hardwood or other types of flooring.

These intelligent machines can be a huge help for households with hectic lifestyles and frequent guests. Robot vacuums can be programmed to clean the house while you're away, and they can return to their docking station if the power runs out. This can help you avoid the stress of having an unclean home and save you time and money.

If you choose an option that is smart-compatible it will be able to connect to your Wi-Fi network and connect with your smartphone. This enables you to control the device with an app to schedule cleaning sessions and monitor your battery status and mapping history. If your robovac comes with cameras it can also be used with the app to review photos of your space. This is useful for identifying objects that the robot may have missed in its previous cleaning session, such as pets toys or chewed-up socks.

The majority of top robots offer this type of smart integration. Certain robots are compatible with Google Assistant. This means that you can turn them on simply by dictating a command via an intelligent speaker. However, some devices may be unable to communicate with Google Assistant, due to issues with signal strength or proximity to the location. Making sure the device is updated, minimizing barriers between it and your Wi-Fi router, or even thinking about an extender that connects to Wi-Fi could solve this issue.
