If you’ve decided to purchase a robot vacuum this year, you may be wondering which one is right for your home or office.

When it comes to choosing a robot vacuum, it’s helpful to make a list of essential features to narrow your choices. For example, if you need to clean a larger area, consider a robot vacuum with a longer battery life. For those with pets, there are a few robot vacuums with no-tangle brush rolls for fuss-free cleaning. 

Learn what robot vacuums have to offer with this buying guide, including a checklist of options to consider as well as quality robot vacuum recommendations from top brands. 

What to know about robot vacuums

Robot vacuums vs. regular vacuums

Operation: The main difference between robot and regular vacuums is the way they operate. Robot vacuums traverse floors independently, where regular vacuums require pushing or pulling by the user. 

Attachments: Regular vacuums may have attachments or tools for specialized cleaning of corners, curtains or upholstery. Robot vacuums generally lack these attachments and specialized capabilities. However, some models have dedicated corner-cleaning functions. 

Noise level: Many users report regular vacuums are noisy or intimidating to pets. Robot vacuums operate more quietly. Many robot vacuums have sensors that detect pets to move around them, too. 

Size: Robot vacuums are significantly smaller than regular vacuums, which means their dustbins are also smaller. As a result, users need to empty dustbins more often. Regular vacuums can go through several cleanings before their dustbins require emptying. 

Setting up a robot vacuum

Robot vacuums allow users to customize floor cleaning through companion apps. Depending on the device’s capabilities, users can set up cleaning schedules, create no-cleaning zones or initiate new cleanings for messes.

Before users reach this point, however, many robot vacuums run initial mapping cycles where they learn the layout of the home. They adapt to clean more efficiently based on variables like floor type, furniture obstacles or debris concentration.

Maintaining a robot vacuum

Generally speaking, robot vacuums are considered low-maintenance devices. Besides emptying the dustbins, users may need to replace filters or clean brush rolls, and that’s it. 

Many robot vacuums let users know if there’s a device malfunction or if it requires service or repair. This information is usually shared in the app, though some robot vacuums may have on-board LED indicator lights or alarms to alert them as well.

Cost of robot vacuums 

Entry-level robot vacuums cost $150-$300, while mid-range models come in around $400-$650. High-end robot vacuums run $700-$1,200. 

Features of robot vacuums

Dynamic cleaning

Robot vacuums are appreciated for their dynamic cleaning capabilities. Some models have advanced floor mapping technology, like iRobot Roomba s9+, which delivers more comprehensive cleanings. 

Low-profile design

ILIFE V3s Pro Robot Vacuum Cleaner

A few robot vacuums have low-profile designs, which make them small enough for cleaning beneath low-clearance furniture. ILIFE V3S Pro and eufy by Anker Boost IQ RoboVac 12 both have slender designs and are less than 3 inches tall. 

Longer runtime

Shark ION AV753

Robot vacuums with longer runtimes are attractive to consumers who schedule whole-house cleanings. Rather than interrupting cleaning to charge themselves, robot vacuums like Shark ION AV753 are capable of running for a whopping 110 minutes on a full charge. 

Quiet operation

Several robot vacuums on the market now offer quiet operation, such as eufy by Anker BoostIQ RoboVac 30C. These robot vacuums are considered less intrusive to work-from-home professionals, remote learners and even pets. 

Designed to clean pet messes

Powerful suction

ILIFE V80 Max

Robot vacuums with powerful suction, such as ILIFE V80 Max, are suitable for homes with high-pile carpets. Debris and dirt sit much deeper between fibers, and the extra suction is often necessary to lift these particles. 

Voice command

Many robot vacuums have smart assistant integration, in which they respond to voice commands to initiate cleanings. iRobot Roomba 891 and eufy by Anker RoboVac G30, for example, are both compatible with Alexa.
