Most can both vacuum or mop decently—however not each
Most combos have been in a position to vacuum effectively or mop considerably decently—however not each (and positively not on the identical time).
The $1,300 Dreame X30 Extremely, for instance, picked up essentially the most dry particles, however its mopping efficiency was among the many worst in its worth vary.
Inversely, the Roborock Qrevo and Qrevo MaxV fashions mopped okay, however their vacuuming was subpar.
John Ord, a lead engineer at Dyson, defined that the necessity to pack in a water tank and fluid-delivery and mopping techniques will essentially compromise vacuuming efficiency—there’s solely a lot tech you’ll be able to cram into one tiny bot. That’s why his firm targeted on its bot’s vacuuming energy, as an alternative of including a mopping perform, Ord stated.
Most machines declare they’ll vacuum and mop on the identical time, however I discovered the arduous means that it’s often higher to sort out moist spills within the mop-only mode (or, higher but, by hand).
I attempted to mop up a tablespoon of milk and some Cheerios utilizing the $1,200 Ecovacs Deebot X2 Omni. As an alternative of cleansing it, this machine first smeared the spill round after which began rattling and gurgling, unable to dock or cross thresholds.
After cleansing, drying, and retrying, I declared the bot damaged. (The Deebot X2 Omni’s guide states that the machine shouldn’t be used on moist surfaces, and a spokesperson instructed us it’s industry-wide observe to wash spills earlier than working the robotic. Different corporations, like Eufy, Narwal, Dreametech, and iRobot, claimed their robots may deal with small portions of liquid.)
Although most machines claimed to have some type of hair-detangling know-how, solely the Narwal Freo X Extremely succeeded in sucking in 18-inch-long strands and ferreting them to the bin (as an alternative of wrapping them across the brush roll).
They battle with dried stains
Even robots costing upwards of $1,500 didn’t possess any magical stain-erasing powers. The truth is, many of the bots would roll over dried milk or espresso stains a couple of times after which quit, leaving the stain as a ghostly reminder of breakfast—or, worse, spreading it throughout the room.
The Eufy X10 Professional Omni ($800) is among the least costly fashions with rotating pads that I examined. It was in a position to take away lighter dry espresso stains by going over the identical spots a number of occasions, nevertheless it didn’t make a dent in heavier espresso or milk stains. (It did a surprisingly good job on caramel syrup, a class all different machines fumbled.)

Solely three fashions—the Roborock Qrevo MaxV, the Narwal Freo X Extremely, and the Yeedi M12 Professional+—managed to erase the dried espresso stains fully. (The Roborock and Narwal machines have dirt-detection sensors, which impel the robotic to go over the stain greater than as soon as.)
And solely the Narwal robotic may vanquish the milk stain. However it took the machine 40 minutes, with the robotic working backwards and forwards between the stain and the dock to wash its mops and refill its water reservoir. As compared, it took us lower than half a minute to wipe up the identical stain with heat water and a Bona Premium Microfiber Mop.
They’re inconsistent navigators
The robots I examined have been filled with navigation options.
You possibly can program them to give attention to or keep away from particular areas of your house or to wash the bed room final, and you’ll comply with them alongside in actual time on little interactive maps of your flooring plans.
The bots declare to avoid obstacles and differentiate between arduous flooring and carpets. However frustratingly typically, they obtained misplaced, confused, or entangled, or they began mopping the incorrect kind of floor.
After I despatched the Dreame L20 Extremely ($850) on its mop run, it initially averted the dried-on stains we’d positioned as a result of it obtained confused by the blue painters’ tape we’d used to mark the realm. (Possibly it mistook the tape for a drop or an impediment?) The robotic approached the stains solely after the tape had been eliminated.
Then again, solely a handful of the machines I examined averted our faux poop reliably, together with the L20 Extremely and its cousin, the Dreame X30 Extremely ($1,300). These two even confirmed little poop icons on their map. (The pair got here out among the many finest in our vacuuming exams, too.)
In the meantime, the Ecovacs Deebot T30S obtained misplaced on a rug, spinning in circles and really mopping the rug with its pads. Shortly after, it obtained caught on the infant bouncer (it will definitely managed to free itself however rapidly returned and obtained hung up once more).
I noticed different combos spinning endlessly whereas trying to find their docks or leaving areas they’d been instructed to wash untouched. But in addition they typically had a magnetic attraction to obstacles I needed them to keep away from, like cords or poop.
And the entire fashions have been vulnerable to ignoring baseboards and thresholds, leading to an accumulation of grime across the edges of a room.
The Roborock Qrevo and the Qrevo MaxV have been comparatively dependable navigators, cleansing in an orderly sample and discovering their means again to their docks, with out quitting mid-job or getting caught on the sting of a rug. However in contrast to the Eufy X10 Professional Omni, which, in my exams, detected obstacles all the way down to the scale of a rubber band, the Roborock machines drove over cables and poop with out hesitation.
On the plus aspect, they’re good climbers and don’t quit simply. A bunched-up pet rug? No downside! A ¾-inch threshold? They’ll simply bulldoze their means over it.
The more-advanced bots had sensors that supposedly permit them to detect several types of flooring, so that they gained’t begin mopping your Persian rug. However I discovered that after they have been on carpets, even these bots that efficiently raised their mopping pads (often about ¾ of an inch) nonetheless left the sides of the rug damp. This may be significantly problematic if the machine crosses a light-colored carpet after mopping up espresso, a brightly coloured drink, or urine.
The one machine that didn’t moist rugs in any respect was the iRobot Roomba Combo J9+, which elegantly lifted its mop pad above its physique. (Sadly, it wasn’t superb at mopping when it was truly purported to.)
Some bots, just like the Ecovacs Deebot T30S and the Yeedi M12 Professional+, raised their mopping pads solely barely. So that you’d have to roll up your carpets altogether earlier than mopping. And each bots began to actively mop the rug every now and then.
They’re giant, loud, and require upkeep
The bots with self-emptying docks weigh between 10 and 30 kilos, and so they have about the identical footprint as a big rubbish can. Because of the measurement and heft of those bots, you’ll be able to’t simply use them on a number of flooring and even in numerous areas of a house.
The bots are noisy when self-emptying, and it’s hardly a hands-off expertise. You possibly can push off emptying the mud bag till it’s about to blow up, however you’ll be able to’t precisely ignore a bucket of fetid mop water sitting in your dwelling area.
Some corporations have began including auto-refill and drainage techniques, however that is nonetheless a comparatively uncommon characteristic. (I needed to strive the SwitchBot S10, which is meant to connect with your plumbing system, however wasn’t in a position to get it going.)
Both means, the realm of the dock that washes the mop pads wants common scrubbing, because it tends to gather muck and liquid. You additionally want to sometimes machine-wash and exchange the pads.
New luggage, brushes, and filters add to ongoing bills. Roborock’s brush roll, as an example, is especially susceptible to wreck—one tangled cable and it appears to be like like a canine’s chew toy.
However their apps are fairly slick
To their credit score, many of the robotic vacuum-mop combos I examined have been a breeze to arrange.
After putting in your machine, you plug it in, obtain the app, and scan a code or choose your mannequin from a listing. The app then walks (and talks) you thru connecting your machine to your Wi-Fi so you’ll be able to management it with its app.
After all, there have been outliers. iRobot’s app is vulnerable to crashing, and I spent hours making an attempt to provoke the SwitchBot S10. After it failed to connect with our Wi-Fi, I contacted customer support and was instructed that my Wi-Fi ID and password shouldn’t have particular characters. Regardless of a SwitchBot spokesperson later assuring me this requirement was eliminated and giving me troubleshooting ideas, I nonetheless couldn’t get the machine to work.
Essentially the most feature-packed apps come from Roborock and Ecovacs. When you’ve arrange your bot and mapped your house, the apps’ pretty correct maps allow you to divide and label rooms and arrange no-go zones.
In addition they allow you to select between vacuuming and mopping (or each), alter suction energy, and fine-tune how a lot water and scrubbing energy the mop makes use of. You possibly can even create “scenes,” a perform that means that you can inform your Roborock Revo or your Ecovacs Deebot to mop the eating room first and vacuum the playroom second, or to hoover on Sundays and mop on Mondays.
This doesn’t imply the apps all the time work completely. In my exams, saved maps generally vanished into skinny air, and newly named rooms reverted to their generic labels.
One in all our older paid testers discovered managing the Roborock robots by means of the app a “cognitive and visible effort,” whereas acknowledging, “It retains the mind sharp.” Others remarked that they wished the app had extra explanations. All of our testers discovered the Roborock app’s distant management (which lets you take over and management the robots’ route) to be unintuitive.
