Robotic vacuums have grow to be 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 property cleansing up after your youngsters and pets.
Although iRobot was a groundbreaking robotic vacuum model within the US, the market has grown exponentially previously 5 years. In an try to sustain with growing 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 looking for a robotic vacuum.
Additionally: The perfect robotic vacuums for 2024: Skilled examined and reviewed
Selecting a model and a robotic vacuum will be difficult, with decisions of self-washing mops, robust suction energy, self-emptying dustbins, and different further equipment and options. Our mission at ZDNET is to interrupt down which options are finest suited to which individuals and which vacuums are the perfect in the marketplace by way of complete testing and analysis.
How we check robotic vacuums in 2024
ZDNET has a number of employees reviewers testing robotic vacuums to ship clear, unbiased evaluations and data that helps readers select the perfect robotic vacuum for his or her wants. Up to now, we have examined round 30 robotic vacuums, together with robotic vacuum mop combos.
As a sensible residence fanatic and robotic vacuum fanatic, I get pleasure from testing robotic vacuums in my residence, the place I can expose these gadgets to totally 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 check robotic vacuums in every surroundings.
What makes a robotic vacuum ZDNET beneficial?
At ZDNET, we solely advocate robotic vacuums that we have examined ourselves, so our group recommends each primarily based on real-world expertise. For a robotic vacuum to be ZDNET-recommended, we count on it to fulfill a number of necessities:
- Efficiency: We think about options like suction energy and the way successfully the robotic vacuums up particles on totally different flooring varieties. 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 wash the specified areas on a single cost or if the robotic options computerized recharge-and-resume capabilities.
- Consumer expertise: The person 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 perfect 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 just isn’t straightforward. We consider whether or not a tool delivers on its specs, together with how effectively its mopping function works, whether or not it really is ‘essentially the most highly effective suction in the marketplace,’ the way it cleans tight areas, and different distinctive differentiating options.
- System longevity: As a result of robotic vacuums are costly, we all know they are not impulse buys—as an alternative, they’re rigorously 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 person upkeep necessities.
Unboxing course of
From starting to finish, my in-home robotic vacuum testing course of entails 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 further options that make it stand out from rivals. These might embody a self-emptying handheld vacuum, an extendable mop pad, or a sweeper brush.
Organising a testing surroundings
The ZDNET/CNET testing lab has totally 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 likely to conduct most of my testing there. I do that to guage how the robots carry out when amassing pet hair and mud and the way they clear up the kitchen.
The primary flooring of my residence additionally has totally different flooring varieties, 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 wash up. Robotic vacuum customers favor a linear cleansing methodology, the place the robotic navigates the realm in traces, making certain no spots are missed and leaving carpet traces that point out the ground’s simply been vacuumed.
Nonetheless, some robotic vacuums clear in numerous patterns or have totally different mapping procedures, so I wish 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 about up, I let it run by way of the home to create an area map. To do that, it is best to wash up gadgets from the ground and place furnishings the place it is purported 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 exploit totally different particles varieties to see how the robotic suctions every up. I’ve discovered glow-in-the-dark sand that I can unfold on totally different flooring varieties to check 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 examine that weight to what the robotic picked up.
Widespread particles in my testing merchandise consists of kinetic sand, espresso grounds, cracker crumbs, Cheerios, pet hair, and kibble.
Navigating obstacles
Testing robotic vacuums additionally entails 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 below couches, others wrestle to keep away from massive particles on the ground and get their brush curler jammed.
This is the totally different know-how 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 vary path to navigate round it.
- Infrared sensors: These sensors are a primary 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) know-how 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 format.
- LiDAR sensors: The Mild detection and ranging (LiDAR) kind 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 primarily based 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 determine them.
Throughout testing, I carefully monitor how robotic vacuums navigate furnishings and tight areas and whether or not they know to keep away from small ones. Having to select up each single merchandise or cable from the ground earlier than operating a robotic vacuum detracts from the comfort one would count on from such a tool. I favor to have my robotic vacuum keep away from my wayward charging cable reasonably than have it get caught on it and reduce its cleansing brief 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 exploit 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 arduous flooring, like dry mud and low. After the robotic is completed, I guarantee to examine the flooring to see whether or not it leaves streaks or residue.
Robots are likely to mop superficially. Many drag a microfiber pad throughout the ground that 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 activity. However very like if an individual had been dragging a moist wipe or microfiber fabric throughout soiled flooring, the pad will inevitably get too soiled to wash 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 totally different testing environments that robotic vacuums should run by way of.
Chris Bayer/ZDNET
Together with my testing in my residence surroundings, we additionally check almost 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 set 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 totally different flooring surfaces, together with low-pile, medium-pile, and arduous flooring.
Lab testing requires totally different methodologies for numerous particles varieties. 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.
Further options
Throughout efficiency testing, I make be aware of any particular options that make the robotic vacuum in query totally different from others. Completely 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 components carry out as promised and if they’re really distinctive in the marketplace.
Consumer expertise
The app expertise could make or break a robotic vacuum, particularly for customers who do not leverage good integrations, like Amazon Alexa or Google House, for voice management. If a person 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 hook up with the robotic while you open the app. Consumer-friendliness makes an app straightforward to navigate, but it surely additionally provides customers quite a lot of capabilities and customizations to allow them to really feel in charge of their system.
Lengthy-term testing
I check all robotic vacuums for at the least a month, however typically, I write about my first impressions inside per week or two of testing. Whereas I check robotic vacuums, I make sure 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 abruptly 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 challenge, so long-term testing is essential to evaluate how effectively a robotic vacuum performs.
Choosing the proper robotic vacuum relies on a number of exterior components and person preferences, however a number of components should be thought-about to make sure it meets the person’s wants. Listed below are some key components to bear in mind when selecting a robotic vacuum:
- Ground varieties: Completely different circumstances require a distinct set of options. When you have largely carpet in your house, you in all probability do not want a high-end mopping function in a robotic vacuum, however you will have robust suction. Equally, when you have largely arduous 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. For those who do not need 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 know-how that identifies and avoids going over pet messes.
- Battery life: When selecting a robotic vacuum, think about the realm you need it to cowl and whether or not you’d prefer it to wash the whole space on a single cost. Bigger areas, like a complete flooring, could require an extended battery life. Additionally, think about that almost all fashions can routinely recharge and resume cleansing in the course of a session.
- Suction energy: Pets improve pet hair, dander, mud, and particles in your flooring. Houses with pets might use robust suction to take away particles from carpets and corners. Robust suction is nice for properties with pets and lots of carpets, however a 10000Pa suction energy is not vital for arduous flooring.
Incessantly 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 wash flooring routinely. 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 relies on the mannequin, however you’ll be able to anticipate 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 routinely throughout a cleansing session after which resume the job when the battery is sufficiently charged.
Robotic vacuums have grow to be refined to the purpose the place there are fashions that may deal with pet hair extra effectively than others. Many fashions function robust suction and brushes designed to select 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 must be changed each seven weeks at most.
Robotic vacuum and mop combos 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 scrub the mop pads, in order that they require the person to fill the clear water tank and empty the soiled water tank each few cleansing periods. These fashions additionally require customers to wash the bottom station’s washing sink, the place the mop pads are washed, each few cleanings.
