Best Overall: eufy BoostIQ RoboVac 30C MAX

eufy BoostIQ RoboVac 30C MAX
What We Like
  • Height-adjustable suction

  • Works well on pet hair

  • Quiet operation

What We Don't Like
  • App tends to freeze

  • Difficulty connecting to Wi-Fi

If you’re on the hunt for a robot vacuum that's powerful and efficient, look no further than the eufy BoostIQ RoboVac. This mid-price robotic vacuum is ideal for use on hardwood floors, as well as low- and medium-pile carpets, and it has a number of useful features that make it stand out from other robotic vacuums. 

This model from eufy includes improved suction power, as well as quiet operation and the brand’s signature slim design—the vacuum is less than 3 inches tall, so it can glide underneath low furniture. You can control this robotic vacuum via your smartphone, Amazon Alexa, or Google Home, and it comes with 13 feet of boundary strips that let you cordon off areas where you don’t want it to go. The RoboVac also has BoostIQ technology, which automatically increases suction when needed, and it can run for up to 100 minutes per charge. 

While this robotic vacuum does a good job of picking up hair and dirt from both hardwood floors and carpets, it’s important to note that this model doesn’t have “floor mapping” technology like more high-tech robot vacuums, so it cleans in a random pattern. 

"Overall, Fluffy did a great job vacuuming regular household dirt and dust, including along the wall and under the dining table. In fact, the vacuum has a perimeter setting that hugs the baseboards really well. The dual brushes reach out beyond the vacuum’s round body to sweep dirt into the suction area."—Stacey L. Nash, Product Tester

Best Budget: Coredy Robot Vacuum Cleaner

What We Like
  • Affordable

  • Long battery life

What We Don't Like
  • No app integration

  • Louder than expected

The Coredy Robot Vacuum Cleaner is a hidden gem, thanks to its impressive cleaning abilities and low price. This vacuum can run for up to 110 minutes per charge, and it boasts an auto-adjusting cleaning head that increases suction when it moves from tile or hardwood floors onto carpets. It has a slim 2.7-inch profile that fits under furniture easily, and it even comes with a remote control that lets you select four cleaning modes and schedule a vacuuming time. Plus, it has a double filter system to more effectively capture dirt and dust as it cleans. 

As powerful as the Coredy Robot Vacuum is, it’s surprisingly quiet. If you’re looking to get the most bang for your buck, you won’t be disappointed in this pick.

Best Splurge: iRobot Roomba s9+ 9550 Wi-Fi Connected Robot Vacuum

iRobot Roomba
What We Like
  • Intelligent mapping

  • Automatic dirt disposal

  • Extremely maneuverable

What We Don't Like
  • Expensive

  • Louder than expensive

The iRobot Roomba s9+ is the best of the best in the robotic vacuum market, but it doesn’t come cheap. We think this high-end model is worth the splurge thanks to its three-stage cleaning system, home-mapping abilities, and automatic emptying.

You’ll be blown away by the next-gen technology of the Roomba s9+. It delivers up to 40 times the suction power of previous Roomba models, and when its dust bin is full, it goes back to the charging base to empty itself. This model runs for 120 minutes per charge and has floor-mapping technology, so it can learn, map, and adapt to your home—you’ll be able to tell it to skip a certain room or do a double pass on one area right from your phone. It also comes with a high-efficiency filter that captures 99 percent of mold, pollen, and dust mite allergens. Basically, if you never want to vacuum by hand again, you need this robotic vacuum!

"The s9+ also has a spot-cleaning function, which is a nice additional feature that many other robot vacuums don’t have. When you press the spot-clean button, the s9+ will clean a small area about 3 feet in diameter instead of running through a full cleaning cycle. This is nice if you accidentally spill something or if your cats just had a royal rumble, and there’s a pile of fur left behind."—Lindsay Boyers, Product Tester

Best Smart: iRobot Roomba 675

iRobot Roomba 675
What We Like
  • Compatible with smart home devices

  • Reasonable price point

What We Don't Like
  • Random cleaning path

The Roomba 675 may not be the latest model from iRobot, but it remains a smart pick for a robotic vacuum thanks to its reasonable price, Wi-Fi connectivity, and impressive cleaning performance. This Roomba is effective on hard floors and carpets, and you can control it from your phone, Amazon Alexa, or Google Assistant. 

The Roomba 675 features the brand’s three-stage cleaning system that loosens, lifts, and sucks up small particles and larger debris. It runs for up to 90 minutes per charge and has an edge-sweeping brush that gets dirt out from the edges and corners of the room. There are even dirt detection sensors that let the robot know it needs to focus on certain areas and give them extra passes.

Best for Pet Hair: iRobot Roomba i7+ Robot Vacuum

Roomba i7+ Robot Vacuum
What We Like
  • Powerful suction

  • HEPA filter

What We Don't Like
  • Difficulty docking

Anyone who owns pets knows the struggle of trying to keep hair off of your floor and carpeting. Even if you sweep and vacuum several times a week, you’ll still have balls of hair rolling around under furniture. For this reason, one of the best robotic vacuums for pet owners is the iRobot Roomba i7+, which can be programmed to vacuum on a daily basis and will automatically empty all that pet hair into its base between cleanings.

This high-end Roomba has a 75-minute runtime and intelligently maps floor plans, and you can control it via your smartphone or smart assistant. It has several features that make it ideal for homes with pets, including its high-efficiency filter and multi-surface rubber brushes that won’t get tangled with pet hair like other brushes. Plus, since it empties its dirt bin into the base—which can hold up to two months of dirt and dust—you won’t have to empty the bin after every cleaning session (even during shedding season).

Best for Carpet: iRobot Roomba 614 Robot Vacuum

What We Like
  • Auto-adjusting cleaning head

  • Affordable

What We Don't Like
  • No smart capabilities

  • Dust bin requires frequent emptying

Looking for a robotic vacuum that can keep your carpets looking pristine? Then you’ll want to check out the Roomba 614, one of the top-rated and most affordable models from the popular brand. It features Roomba’s three-stage cleaning system and dual brushes, which loosen the dirt in your carpet before sucking it up. It has an auto-adjusting cleaning head that adapts to the height of the carpet for optimal performance, and the dirt detection sensors let the vacuum know when the spot needs another pass. 

While this vacuum doesn’t have smart capabilities and it might not serve as a full replacement for your standard vacuum, it works great on carpets for quick cleanups and picks up pet hair like a champ. Just make sure you empty its dust bin regularly, as it may fill up quickly. 

Best Vacuum-Mop Combo: Roborock S5 MAX Robot Vacuum and Mop

What We Like
  • Versatile

  • Long battery life

What We Don't Like
  • Weaker on carpeting

Hands-free vacuuming is one kind of creature comfort, but mopping without having to worry about getting your hands (and feet and clothes, for that matter) wet is a whole new level of luxury. If you dream of getting both of these floor-cleaning tasks done in one remote fell swoop, consider the Roborock S5 MAX, a robotic vacuum that mops as well as it sucks up dirt.

Through Roborock's corresponding app, you can map out a precise cleaning routine throughout your home (the app can hold up to four floors' worth of data), noting areas it shouldn't mop, areas that need more water than others, and areas it should avoid completely. If you just want the S5 MAX to vacuum, the mop unit detaches easily and the intense suction gets to shine, tackling all varieties of floor surfaces, even high-pile carpet. And, once you set it off on its chores, it will steadily clean for 3 hours, thanks to its lithium-ion battery.

Best Quiet Operation: Roborock E4 Robot Vacuum Cleaner

Roborock E4 Robot Vacuum Cleaner
What We Like
  • Extremely quiet operation

  • Compatible with Amazon Alexa

What We Don't Like
  • Difficulty docking

One of the biggest perks of having a robotic vacuum is that you can watch TV, get work done, or even sleep through the night while it does all the work—but, in order to enjoy that perk, you need a vacuum that won't make a racket while getting the job done. Roborock's E4 model is an excellent option from a performance perspective, but, thanks to its specific Quiet Mode setting, it's also your best chance at getting a clean home without getting distracted from your show or your night's sleep.

This robotic vacuum cleans thoroughly, moving in tidy rows for up to 200 minutes at a time (if it runs low on juice in the middle of cleaning, it will return to its base, recharge, then go back to where it left off). It easily climbs over doorways and its app comes with a boost setting for carpets. The E4's app also allows you to monitor the cleaning process remotely, start or stop cleaning, and adjust the current mode.

Final Verdict

If you’re looking for a powerful and efficient robotic vacuum to keep your home clean, the eufy BoostIQ RoboVac 30C MAX (view at Amazon) is our top choice. It does an excellent job of picking up hair and dirt from both hardwood floors and carpets. However, the Coredy Robot Vacuum Cleaner (view at Amazon) is a great alternative that has an impressive run time.

What to Look for in a Robot Vacuum

Square footage

Do you plan to use your robot vacuum to clean a whole floor of your house or just a few rooms? If you want your vacuum to cover a large amount of square footage, you’ll want a model that has a longer battery life, a larger dust collection bin, and maybe even self-charging capabilities. 

Carpets

Will your robotic vacuum be cleaning hard floors or carpets? Certain products are designed to handle the transition from one floor type to another without losing suction, which will help it clean better on carpets! Other models are designed to be more efficient at picking up pet hair, which is a bonus for those with furry friends. 

Smart capabilities

High-end robot vacuums can connect to Wi-Fi, sending updates to your smartphone. This can be beneficial if you want to be able to start the vacuum remotely or monitor its progress, but keep in mind that this feature will increase the price tag, often by hundreds of dollars.

FAQs

How do robotic vacuums work?

Generally, robotic vacuums rely on a variety of sensors to determine their path through your home, and where they should go to clean. Some of these sensors help detect "cliffs," or edges that the machine could fall off, while others sense where objects like furniture are in relation to the vacuum and help it avoid bumping into them. More technologically advanced robotic vacuums may also implement machine learning in order to their cleaning done: Mapping software, customizable cleaning preferences via an integrated app, and dirt sensors provide these smart vacuums with additional information to move through your home without incident and clean the areas that need the most attention.

Can a robotic vacuum replace an upright vacuum?

If you find the right robotic vacuum for your home, it can do an excellent job keeping your floors clean and end up saving you some time on routine vacuuming. But, you shouldn't toss out your full size vacuum just yet. Where robotic vacuums are highly effective at regularly cleaning floors, including the hard-to-reach corners of your home, they rarely feature the sheer cleaning power that, say, an upright vacuum does. So, when it comes to deep cleaning a high-pile carpet or any vacuuming job that calls for attachments, you're better off sticking with your upright model.

How do you keep a robotic vacuum from getting stuck under furniture?

Even if you have a smart robotic vacuum, which can learn and adapt to your home's layout, there is always the risk that it will end up stuck under the couch. Luckily, you can prevent this from becoming a recurring issue by choosing a model with a low profile, adding risers to the legs of your furniture, and blocking the way under furniture with string or a virtual barrier. Some models even come equipped with an alert sound you can activate if you lose track of your vacuum's whereabouts.

Why Trust The Spruce?
