Robotic vacuums have turn into indispensable within the cleansing routines of many households — an estimated 14% of People now personal one. You do not have to reside within the Jetsons to have a robotic roaming round your own home cleansing up after your children and pets.
Although iRobot was a groundbreaking robotic vacuum model within the US, the market has grown exponentially prior to now 5 years. In an try to sustain with rising client demand, new and current vacuum manufacturers have entered the robotics market, reaching the purpose of saturation. This has made it tougher to decide on a tool when searching for a robotic vacuum.
Additionally: The very best robotic vacuums for 2024: Skilled examined and reviewed
Selecting a model and a robotic vacuum will be difficult, with decisions of self-washing mops, sturdy suction energy, self-emptying dustbins, and different additional equipment and options. Our mission at ZDNET is to interrupt down which options are finest suited to which individuals and which vacuums are the very best in the marketplace by way of complete testing and analysis.
How we take a look at robotic vacuums in 2024
ZDNET has a number of employees reviewers testing robotic vacuums to ship clear, unbiased evaluations and knowledge that helps readers select the very best robotic vacuum for his or her wants. So far, we have examined round 30 robotic vacuums, together with robotic vacuum mop combos.
As a wise residence fanatic and robotic vacuum fanatic, I take pleasure in testing robotic vacuums in my residence, the place I can expose these gadgets to completely different environments and phenomena, largely triggered by my canine or younger kiddos. Concurrently, ZDNET has a separate laboratory to conduct managed testing and analysis. This information will cowl how we take a look at robotic vacuums in every atmosphere.
What makes a robotic vacuum ZDNET really helpful?
At ZDNET, we solely advocate robotic vacuums that we have examined ourselves, so our group recommends every one based mostly on real-world expertise. For a robotic vacuum to be ZDNET-recommended, we anticipate it to satisfy a number of necessities:
- Efficiency: We contemplate options like suction energy and the way successfully the robotic vacuums up particles on completely different flooring sorts. Good efficiency additionally consists of evaluating its navigation and mapping programs, together with impediment avoidance. We assess whether or not the battery life is adequate to scrub the specified areas on a single cost or if the robotic options automated recharge-and-resume capabilities.
- Person expertise: The consumer expertise is central to having fun with a tool, from unboxing to long-term use. At ZDNET, we consider whether or not a tool options easy setup, use, and upkeep and the very best viewers for which every robotic vacuum is finest suited.
- Versatility and options: Producers usually make guarantees to make their robots stand out from the competitors, however delivering on these guarantees shouldn’t be simple. We consider whether or not a tool delivers on its specs, together with how properly its mopping function works, whether or not it actually is ‘essentially the most highly effective suction in the marketplace,’ the way it cleans tight areas, and different distinctive differentiating options.
- Machine longevity: As a result of robotic vacuums are costly, we all know they are not impulse buys—as an alternative, they’re fastidiously thought-out purchases. By testing these robots for prolonged intervals of time, we assess whether or not they ship constant efficiency with minimal points in the long run, sturdiness, and consumer upkeep necessities.
Unboxing course of
From starting to finish, my in-home robotic vacuum testing course of includes fixed note-taking and visible documentation with pictures and movies. I start by unboxing the robotic vacuum and taking pictures and notes of the method, together with the setup expertise, packaging high quality, and equipment.
I consider the robotic’s construct high quality and design and assess whether or not it has additional options that make it stand out from rivals. These might embrace a self-emptying handheld vacuum, an extendable mop pad, or a sweeper brush.
Organising a testing atmosphere
The ZDNET/CNET testing lab has completely different environments to run and observe robotic vacuums as they carry out.
Chris Bayer/ZDNET
As a result of my canine stays on the primary flooring of my residence, I are inclined to conduct most of my testing there. I do that to guage how the robots carry out when gathering pet hair and mud and the way they clear up the kitchen.
The primary flooring of my residence additionally has completely different flooring sorts, together with tile, hardwood, and short- and medium-pile carpet.
I even have a 10-foot by 5-foot enclosure on my carpet and hardwood to guage the patterns vacuums use to scrub up. Robotic vacuum customers want a linear cleansing methodology, the place the robotic navigates the realm in strains, guaranteeing no spots are missed and leaving carpet strains that point out the ground’s simply been vacuumed.
Nonetheless, some robotic vacuums clear in numerous patterns or have completely different mapping procedures, so I prefer to see how a person robotic vacuum navigates my enclosure and how briskly it does it to report any variations with rivals.
Efficiency testing and metrics
As soon as the robotic is ready up, I let it run by way of the home to create an area map. To do that, it is best to scrub up gadgets from the ground and place furnishings the place it is presupposed to go to make sure the robotic creates an correct map.
Mapping
Mapping can contain operating the robotic for a mapping spherical the place it vacuums your total flooring, which might take as much as about an hour, or it could simply roll round making a map with its LiDAR sensors, which ought to solely take a couple of minutes.
Testing suction energy
As a result of I take notes and pictures all through the method, I consider any guarantees made by the producer and assess whether or not the robotic delivers on them. If a robotic vacuum guarantees the strongest suction in the marketplace, I see the way it lives as much as this declare.
I take advantage of completely different particles sorts to see how the robotic suctions every up. I’ve discovered glow-in-the-dark sand that I can unfold on completely different flooring sorts to match how a lot the robotic picks up visually. I additionally use a kitchen scale to weigh how a lot sand or crumbs I unfold after which evaluate that weight to what the robotic picked up.
Frequent particles in my testing merchandise consists of kinetic sand, espresso grounds, cracker crumbs, Cheerios, pet hair, and kibble.
Navigating obstacles
Testing robotic vacuums additionally includes watching how they navigate round corners, furnishings, and tight areas and the way they keep away from obstacles. Whereas some robotic vacuums could wrestle to maneuver round furnishings or beneath couches, others wrestle to keep away from massive particles on the ground and get their brush curler jammed.
This is the completely different expertise that robotic vacuums use for impediment avoidance:
- Bump sensors: Some easier robotic vacuums have bump sensors that detect bodily contact with objects. When these robots bump right into a chair leg, they know to alter path to navigate round it.
- Infrared sensors: These sensors are a fundamental impediment avoidance methodology and a step up from bump sensors. Infrared sensors emit infrared mild and measure the reflection to calculate the space from objects to keep away from collisions. These sensors are additionally generally used to detect stairs and hold the robotic from falling.
- VSLAM sensors: Visible simultaneous localization and mapping (VSLAM) expertise makes use of cameras to map the robotic’s cleansing space. The pictures captured by the cameras are processed with algorithms to grasp the realm’s structure.
- LiDAR sensors: The Gentle detection and ranging (LiDAR) sort of sensor creates an correct, high-resolution map of the realm, reaching excessive ranges of element. LiDAR sensors emit pulses of laser mild and measure the time it takes for the laser to bounce again after hitting an object. The robotic then calculates the space based mostly on the time delay and creates a exact 3D map of its environment.
Some robotic vacuums mix synthetic intelligence (AI) algorithms with their sensor array to map out obstacles on the ground, utilizing picture recognition to establish them.
Throughout testing, I intently monitor how robotic vacuums navigate furnishings and tight areas and whether or not they know to keep away from small ones. Having to choose up each single merchandise or cable from the ground earlier than operating a robotic vacuum detracts from the comfort one would anticipate from such a tool. I want to have my robotic vacuum keep away from my wayward charging cable moderately than have it get caught on it and reduce its cleansing quick whereas I am out of the home.
If a robotic guarantees to keep away from obstacles strewn across the flooring, I guarantee it delivers. To check it, I take advantage of bigger particles, like socks, wadded-up paper towel sheets, cables, small items of paper, small toys, leaves, and different gadgets.
Mopping function
A robotic vacuum with a bonus mopping function is a good way to maintain your flooring clear and shining. Sadly, some promise greater than they’ll ship.
Throughout testing, I observe how the robotic mops and the way successfully it removes stains on onerous flooring, like dry mud and occasional. After the robotic is completed, I guarantee to verify the flooring to see whether or not it leaves streaks or residue.
Robots are inclined to mop superficially. Many drag a microfiber pad throughout the ground which will or could not vibrate, whereas others have two rotating microfiber mop pads. Many could return to the bottom station periodically to wash their mop pads, then return to the cleansing process. However very similar to if an individual had been dragging a moist wipe or microfiber fabric throughout soiled flooring, the pad will inevitably get too soiled to scrub successfully — the identical occurs with robotic mops.
Extra lately, robotic mops have developed into mop rollers, which spin contained in the robotic and are scrubbed with clear water whereas the soiled water is stored individually. This final modality ensures the robotic solely mops with clear water.

ZDNET’s lab testing
ZDNET’s testing lab has completely different testing environments that robotic vacuums should run by way of.
Chris Bayer/ZDNET
Together with my testing in my residence atmosphere, we additionally take a look at practically each robotic vacuum on the ZDNET lab in Louisville, Ky., for a extra managed expertise.
On the lab, the group unboxes the robotic vacuum, measures the nozzle’s width, and weighs the vacuum’s dustbin. The lab has a testing rig with a hard and fast floor space to sprinkle particles on and consider how the robotic cleans it.
Particles consists of sand, black rice, and pet hair and is unfold over completely different flooring surfaces, together with low-pile, medium-pile, and onerous flooring.
Lab testing requires completely different methodologies for varied particles sorts. Sand and black rice are assessed with weight, whereas pet hair inevitably will get tangled on the comb curler, so the outcomes are typically sight-based.
Extra options
Throughout efficiency testing, I make word of any particular options that make the robotic vacuum in query completely different from others. Totally different robotic vacuums promote distinctive options to face out, whether or not it is a sq. form, distinctive impediment avoidance, extendable arms, particular mopping options, or different bonus functionalities.
I consider whether or not these differentiating elements carry out as promised and if they’re actually distinctive in the marketplace.
Person expertise
The app expertise could make or break a robotic vacuum, particularly for customers who do not leverage sensible integrations, like Amazon Alexa or Google Dwelling, for voice management. If a consumer depends on the app to manage their robotic vacuum, the app must be user-friendly and dependable.
Throughout testing, I assess how the app performs and whether or not it is dependable or not. I’ve discovered some robots have inconsistent connection points, making you wait too lengthy to connect with the robotic whenever you open the app. Person-friendliness makes an app simple to navigate, but it surely additionally offers customers a wide range of capabilities and customizations to allow them to really feel answerable for their gadget.
Lengthy-term testing
I take a look at all robotic vacuums for at the very least a month, however typically, I write about my first impressions inside per week or two of testing. Whereas I take a look at robotic vacuums, I be certain that my evaluations are up to date as new observations come up.
Although many good options are strikingly apparent when testing a robotic, points usually tend to come up throughout repeated, long-term testing. I’ve had robots all of a sudden cease following the map they created after months of utilizing it, forcing me to delete the map and recreate it. After a couple of months of use, I’ve additionally had a robotic current a brush roll concern, so long-term testing is necessary to evaluate how properly a robotic vacuum performs.
Selecting the best robotic vacuum will depend on a number of exterior elements and consumer preferences, however a number of elements should be thought of to make sure it meets the consumer’s wants. Listed below are some key elements to bear in mind when selecting a robotic vacuum:
- Ground sorts: Totally different circumstances require a distinct set of options. In case you have largely carpet in your house, you most likely do not want a high-end mopping function in a robotic vacuum, however you’ll need sturdy suction. Equally, if in case you have largely onerous flooring, you probably want good suction and an incredible mopping function.
- Mapping and impediment avoidance: Entry-level robotic vacuum fashions use infrared sensors, whereas high-end fashions leverage LiDAR, VSLAM, and AI to navigate properties and acknowledge objects. When you do not wish to decide up each sock and charging cable out of your flooring earlier than every cleansing, you’d do higher with a high-end mannequin with efficient impediment avoidance. Some iRobot fashions have P.O.O.P., a expertise that identifies and avoids going over pet messes.
- Battery life: When selecting a robotic vacuum, contemplate the realm you need it to cowl and whether or not you’d prefer it to scrub your complete space on a single cost. Bigger areas, like a complete flooring, could require an extended battery life. Additionally, contemplate that almost all fashions can robotically recharge and resume cleansing in the midst of a session.
- Suction energy: Pets improve pet hair, dander, mud, and particles in your flooring. Properties with pets might use sturdy suction to take away particles from carpets and corners. Sturdy suction is nice for properties with pets and lots of carpets, however a 10000Pa suction energy is not essential for onerous flooring.
Continuously Requested Questions
Robotic vacuums, like conventional vacuums, have a suction system with a brush curler that picks up particles from the ground and disposes of it in a dustbin inside. Moreover, robotic vacuums use a mixture of sensors and a navigation system to scrub flooring robotically. They’re able to cleansing an space, avoiding obstacles of their path, after which returning to the charging dock to recharge.
A robotic vacuum’s battery life will depend on the mannequin, however you possibly can look forward to finding robots that may final from 60 to 160 minutes per cost. The upper-end fashions supply the longest battery life. Most robotic vacuums can recharge robotically throughout a cleansing session after which resume the job when the battery is sufficiently charged.
Robotic vacuums have turn into subtle to the purpose the place there are fashions that may deal with pet hair extra effectively than others. Many fashions function sturdy suction and brushes designed to choose up pet hair successfully, with some even together with a built-in detangling system throughout the robotic to take away pet hair from the comb because it rolls throughout cleanings.
As a naked minimal, a robotic vacuum that may deal with pet hair ought to have a rubber brush, a big dustbin, and a self-emptying system, with bonus factors if the robotic can self-empty as wanted throughout a cleansing.
Sure, robotic vacuums require routine upkeep. Common upkeep consists of cleansing and changing filters, emptying the dustbin, checking brushes for hair or particles, and changing sweeper brushes.
If a robotic vacuum has a self-emptying system that empties its dustbin right into a mud bag on the base station, it ought to be changed each seven weeks at most.
Robotic vacuum and mop mixtures can require extra intervention. Conventional mixture robots require manually washing the mop pads and refilling the water tank.
Self-washing robotic vacuums and mops return to the dock to clean the mop pads, so that they require the consumer to fill the clear water tank and empty the soiled water tank each few cleansing classes. These fashions additionally require customers to scrub the bottom station’s washing sink, the place the mop pads are washed, each few cleanings.
