A Robot Vacuum Cleaner That Also Mops
This robot vacuum cleaner from German manufacturer Karcher makes an impressive debut. Its advanced features, including cliff detection and AI mapping, enabled it to eat biscuit crumbs and pet hair effortlessly, though dust proved a bit more than a problem.
The compatible app adds convenience, allowing you to set virtual walls to help it avoid stairs and furniture, or schedule cleaning at certain times. The sound levels of the machine are high.
Self-emptying
You can reduce time and energy by using a robot vacuum that automatically empty itself. Its docking station holds a large storage bag which, when full, can be taken off and replaced. This means that you don't have to empty a small dustbin on the robot itself, and it can reduce health and hygiene concerns around contact with dust and hair from pets. It also prevents the bin from being full, which can lead to a loss of vacuum, and could result in spilling debris into the living room.
A vacuum that is able to be emptied automatically is especially recommended if you have family members suffering from allergies or hay fever to prevent the reintroduction of dirt back into your home. It's also a great choice for people who lead a hectic life and want to minimize the amount of time they devote to cleaning their home.
Most robot vacs can be controlled by a mobile app and voice commands, which allows you to start, stop or return them to the dock. Some can even tell you when they're tangled up with a broken piece of furniture, or if their battery is depleted.
The higher-end models use cameras and laser sensors to scan their environment, enabling them to work out the most efficient route before tackling each room. This will help them avoid being tripped up by furniture or caught in a cables that are stray.
Modern robot cleaners are able to create detailed maps of your home that are accessible via an app. You can save multiple maps and be able to include 'exclusion zones,' which the robot cleaner is able to avoid. Advanced cleaners with mopping capabilities will also be able to create zones areas for cleaning and add specific furniture pieces to the map to ensure they get cleaned.
Smart apps
Many robot vacuums are compatible with smart-home technology. This means they can be controlled via an app. They may also be able to communicate with smart assistants, such as Amazon Alexa or Google Assistant and you can ask them to clean. This is useful for those who want to avoid having to press the vacuum button, or are worried about children and pets accidentally setting it off.
The bins of most compact robot vacuums aren't big enough which means you'll have to empty them often. Some of the best models are equipped with auto-empty features. They can empty their bin onboard without a need to return to their docking station. This feature is great for those who suffer from hayfever and allergies as it reduces dust that you come into contact with.
Another benefit of robot vacs is the ability to clean your floors. They are more expensive, but are extremely useful for those who don't wish to clean up mess. Certain robots that come with mopping capabilities include a separate water tank, while others combine the two functions into one. They can thus do double duty and save you from the necessity of swapping out attachments.
A good robotic vacuum cleaner uses the map of your home to guide it. Utilizing a combination of sensors such as cameras, lasers and cameras to create an image of your space prior to starting to vacuum or mop. You can then view the maps in your smartphone's app and even create exclusion zones so it won't get in the way of certain furniture pieces.
This feature isn't present on all robot vacs, but it's an excellent alternative for those who struggle with manual cleaning or don't have the time to maintain an entire vacuum each day. It's especially useful for those with messy, high-up spaces because it can clean underneath tables and other difficult-to-reach places. The nozzle of the robot is able to reach furniture and walls without harming them. The intelligent directional system also ensures that the robot can reach hard-to-reach places.
Obstacle avoidance
Object avoidance technology helps robots avoid household clutter and debris during cleaning. It keeps them from slurping substances that will jam or damage internal parts, and it saves you from having to yank stuck items out of suction or move them underneath furniture. A lot of the latest models, like smart home appliances and robotic vacuums, have advanced obstacles avoidance technology that operates in real-time.
If you're looking for the best robot vacuums make sure you select one with the latest obstacle detection systems that operate in a variety of lighting conditions and can recognize an array of objects. The top smart robots use multiple sensors to create a richer understanding of their surroundings. Additionally, they are able to avoid obstacles even when the room layout changes. Some examples of advanced technology for avoiding obstacles include crossed IR sensor 3D structured lighting and ToF sensors (time of flight).
Crossed IR sensor beams are light beams that are focused that are reflected off objects, allowing the robot to detect them. This kind sensor is found in robot vacuums and other cleaning robots. It is particularly useful in dark rooms. Some of the more expensive models have 3D structured light, which emits a pattern of light pulses and uses the way they're distorted to detect objects around them. 3D structured light is often coupled with cameras and crossed IR sensors to create an even more comprehensive obstacle-avoiding system.
Cameras are another technology that is used for robot vacuums and mopping bots. They can be either binocular or monocular and can capture images of the surroundings and apply image processing to detect obstacles. The best robotic vacuums equipped with camera sensors offer a more comprehensive solution for obstacles and can be paired with other technologies to achieve superior results.
iRobot Roomba j7+ is one of the most advanced obstacles-avoidance systems on the market. This model comes with a built-in video camera that can detect objects of different sizes as well as pet waste. IRobot's faith in this technology is so strong that it provides an "Pet Poop Promise" guarantee: in the event that the robot is able to detect pet waste the company will replace the device without cost to customers.
Cleaning
The top robot vacuum cleaners make use of a combination of sensors and lasers to mark out the area they're cleaning. This allows them to avoid bumping into stairs, furniture and other obstacles. They can also determine the need for a specific area to be cleaned twice and then return to their dock if their power is not sufficient or their bins are full.
You can connect your robot vacuum to your smart assistant, such as Alexa or Google Home, and control it with the app on your smartphone. This is particularly helpful when you're away from home and require cleaning or begin a more detailed cleaning. Some models let you manually trigger a clean from the app in case you need to get rid of stains or spills.
You can get robot mops that are just as common as robot vacuums. They're usually available as separate robot mops or hybrid versions with mop attachments. The traditional robot mops comprise plates that attach to the vacuum's underside or back, and a small water reservoir. They also come with mop pads. They're fine to polish freshly vacuumed floors, but they won't remove a sticky stain as the ketchup.
The most sophisticated robot mops come with their own built-in tanks and are designed to clean as they go along. They are more suitable for tough stains, but can take longer to wash a room. Certain models also automatically return to their docks and refill their tanks once they're full, which can be beneficial if you suffer from allergies or hay fever.

The iRobot Scooba 450 is a top pick. It was the only robotic vacuum to make our Best Buy list and it did well on hard floors and carpets. It's a bit expensive however, its excellent performance in our tests means you will save money both on cleaning and electricity. It's also self-emptying so you don't need to empty it manually every time.
