Robot vacuum-maker iRobot to be acquired by Amazon: Here are our favorite tested robot vacuums

Which robot vacuum is best?

One invention that has benefited the modern household is the robot vacuum, so it shouldn’t be surprising that Amazon is purchasing iRobot. Today’s robot vacuums don’t require you to be present during cleaning and can be programmed to work automatically using a digital map of your space. They often also support Wi-Fi connectivity or control through a mobile app. Robot vacuums can vary widely in budget and functionality, so figuring out what your house or space’s needs are is crucial.

Basics of a robot vacuum

How do robot vacuums work?

The most obvious difference between regular vacuums and robot vacuums is that they don’t need to be pushed by the user. Robot vacuums simply use a combination of maneuvers and smart technology to navigate a space independently. They also usually use a combination of cleaning functions, most notably a vacuum, to keep floors clean.

Pros and cons of buying a robot vacuum


  • Using a robot vacuum is time-saving compared to pushing a vacuum or mop.
  • Robot vacuums are highly efficient and may hit spots a human could easily miss.
  • They’re excellent at mitigating pet hair and dander.
  • Most are self-emptying and automatically recharge using a charging dock.


  • Low-end robot vacuums may struggle with large obstacles, so you’ll still have to pick up and clean large objects that could get in the vacuum’s way.
  • Robot vacuums tend to be expensive.

What to look for in a robot vacuum

Automatic dirt disposal

Most robot vacuums include automatic dirt disposal for a certain period. This feature only requires users to empty the dock every month or so. Robot vacuums can range in how long they self-empty, usually requiring manual disposal every 30 to 60 days.

Mobile app and Wi-Fi connectivity

Even today’s mid-grade robot vacuums usually offer control via a mobile app and Wi-Fi connectivity. These options make your control of the robot vacuum more versatile. These digital connectivity options often let you use them with other smart home features, too.

Compatible with your floors

Robot vacuums are typically designed for carpet and hard floors. However, checking a particular product is crucial because some low-end vacuums may only work with one or the other. Though most are for dusting and vacuuming, you can also find some robot vacuums with attachments for mopping.


Robot vacuums use a rechargeable battery for power, meaning they have limited runtimes before returning to the dock to charge. Most robot vacuums have a runtime of 30 to 120 minutes. Depending on how large your space is and other factors such as the layout of rooms, many robot vacuums can clean an entire home in a single run.

Floor mapping and obstacles

Low-end robot vacuums tend to get stuck, which is why they often compensate with floor mapping. When obstacles are in the way, most mid- and high-grade vacuums will use sensors to go around them. You can also find robot vacuums with added features such as smart floor mapping, virtual boundary strips or voice controls that you can use to offer more specific cleaning guidelines.
