What to Look For in a Good Robot Vacuum
A quality robot vacuum will keep you on top of pet hair, lint and dust on a daily basis. Many robot vacuums have apps that allow you to schedule cleaning times. You can also set virtual boundaries or "walls," to keep the vacuum away from areas you don't wish to be cleaned.
This smart vacuum and mop creates a home map after its first run, memorizing your home's layout for future tasks. It comes with a large dust bin that automatically emptys and self-cleaning brush roll.
Object Detection
When choosing a robot vacuum cleaner, pick one that can clean up big items such as toys and lamp cords as well as dust particles of fine size. This will ensure that they don't get stuck in the roller brush or left on your floor. This is particularly crucial if the robot will be cleaned frequently by pets or children.
A model that has an efficient engine and plenty of suction is also a good option. This will enable it to be more efficient in getting rid of dust, pet hair, and lint off carpets and hardwood flooring.
The size of your house is another crucial factor to consider. If you have a large home, you may choose a model with multiple cleaning zones that can clean the entire house in one go. Certain models also include mopping functions, which can be used to keep your floors looking fresh and clean.
Robot vacuums are long-lasting but they need to be maintained in a timely and efficient manner. Cleaning the rotating brushes, emptying the dust bin and wiping the sensors clean regularly will ensure that your robot is running smoothly for the years to come. Many owners of robot vacuums that we have spoken with have owned the same machine for a decade or more (and replaced brushes, motors and batteries as they went along).
A basic robot will cost you less than a full-size vacuum cleaner, but they'll still do a great job of keeping up with dirt and pet hair, and lint. You can use them to clean your floors several times per day. They do not have as much technology and are more susceptible to getting jammed or needing manual intervention.
Object Avoidance
The top robot vacuums make use of sensors, cameras or lasers to guide you around your home, avoiding getting stuck or falling on the stairs. They also can avoid obstacles like cords and furniture legs and some models automatically return to their dock or base when they run low on power. Some of the more expensive models come with the ability to map, which allows them to memorize your home's layout and spend less time bouncing off walls.
You don't have to spend lots of money on the most expensive robotic vacuums. You can still find models that do a great job of removing pet hair and dirt from hard surfaces, such as wood, tile and low-pile rug. They can also handle larger debris such as nails that are rusty, metal screws or discarded toys. Some have an automatic base that drains itself, which is great if you do not want to empty it every cleaning session.
Some robotic vacuums have smart features, which make the standard stick vacuum look quaint. They include schedules, zone-targeting, and the capability to control them using an app or voice assistants, such as Alexa. You can also set up cleaning zones and 'virtual walls to block off areas you do not want the robots to enter.
Certain robotic vacuums such as the Eufy 11S and my former top pick the Roborock S8, have obstacle avoidance technology that keeps them from derailing by running into furniture or tangling with cords. Some robot vacuums, like the iRobot Roomba j7+ have more sophisticated AI obstacle avoidance technology that makes use of a camera, processors and algorithms to stay clear of items such as lamp cords and pet waste. It's a little more expensive than the other bots I've tested however, it did a great job of avoiding obstacles within my home. It was also very rarely stuck or derailment while working on my flooring.
The iRobot J7+ was an excellent obstacle avoidance robot however, it didn't always do a great job at avoiding dirt or crumbs on my carpets. It also tends to over-vacuum some areas, which resulted in a lot of extra dust in the filter, and a less-clean house.

Smart Mapping
The best robot vacuums come with an application that lets you alter cleaning modes, create schedules, and see a map of the floor area that is covered by the machine. This is a great feature that other models don't have. It allows you to create profiles that automatically start the robot at specific times, and keep it running continuously. For example, cleaning the living room every day or before dinner.
A good app will allow you to control your robot using voice commands. Certain models are compatible with Amazon's Alexa and Google Assistant, which allows you to control your robot using voice commands.
To enjoy a hands-free and effortless experience, opt for a model with a large dust bin that can hold numerous cleaning sessions before needing to be empty. You can find models that self-empty. This eliminates the requirement to empty the robot after every time you vacuum.
If you're looking for a robot that is more than simply vacuum, you'll need to look at one that can mop your floors. These are usually larger than robotic vacuums and include a tank of water that can hold multiple cleaning sessions' worth of dust and dirt before having to be emptied.
Robots that are more advanced can develop their own maps, and can remember the layout of your home from one cleaning session to the next, preventing them from getting lost or stuck. This can make a big difference in the effectiveness of your robot vacuum, as it will not have to return to where it started when it comes across furniture or walls.
Our test participants who utilized the robot that has this capability found it to be extremely efficient. They could watch TV or do other chores while the robot was cleaning. Some of these models use laser navigation and can create an exact map of your house, which means you can program them to clean only the bedroom after dinner, or each room of the house while you're at work.
App Control
It is best to select a robot that has a mobile application for those who want to modify the frequency of cleaning and select a cleaning mode. You can also see the status of the vacuum and the condition of its dust bin using the app. Some of the best robotic vacuums can be controlled by Alexa, Google Assistant, or Siri Shortcuts.
It is easy to maintain a robot with an washable filter and self-emptying container, particularly when the filter is easily cleaned and washed. Another feature that is great is a powerful brush that gets into corners and along baseboards making it much easier to remove hair and dirt. Some robots are more adept in avoiding chairs' legs than others, and some even have self-cleaning sensors that can prevent the clogging of brushes that can happen in other machines.
Certain robo-vacs come with navigational tools that help them navigate around obstacles and to learn about your home. High-end models are equipped with sensors and cameras that detect obstacles such as furniture, stairs and cords, whereas cheaper models sometimes use boundary strips you place on the floor to mark areas you don't want to enter. Object avoidance can be especially useful for families with children who throw socks and toys all over the house. This allows your robot collect these items instead of scattering.
best shark robot vacuum starting to see more robots that have mops, which are great for people who have hard floors and need to regularly clean them. These robots have a water reservoir that is built into their chassis or as a separate component that can be swapped in when ready to mop. They may need to be refilled more frequently than other types of robots, but they're ideal for homes with floors made of wood that can't be easily cleaned using a vacuum.
These robots are packed with some impressive technology, and cost a lot less than you'd think. In fact, you can get a decent one for less than $200 that can do a decent job of removing pet hair and crumbs from hard floors, and also navigating the edges of lightweight carpets or area carpets. The robot can be programmed to vacuum the room on a regular schedule. It can be controlled remotely through an app or by pressing buttons.
