How often will I actually empty it?
Box claims assume average homes. Pets and bigger homes fill docks faster, so treat 75 to 150 days as a best case and check the bag monthly at first.
A self-emptying dock is the feature that turns a robot from a gadget into a habit. The real question is which kind: a sealed bag you replace every couple of months, or a bagless bin you rinse.
Each one links to its full review further down.

Box claims assume average homes. Pets and bigger homes fill docks faster, so treat 75 to 150 days as a best case and check the bag monthly at first.
It can be. Vacuum Wars’ three-month home test found a bagless Ecovacs dock messier than expected; sealed bags keep dust contained.
Our pick for this: Ecovacs X11 OmniCyclone
Yes, for a few seconds: the dock runs a strong vacuum to pull the robot’s bin clean. Schedule runs for times you’re out.
In the listings we checked on October 24, 2026, a six-pack of Roborock-compatible bags ran about $10. Bagless docks remove that cost.
Fix: Dock bags

Best bagless dock, no dust bags
A roller-mop robot whose dock never needs a dust bag.
Why it’s on this list: Bagless and mop-washing, with PowerBoost charging during wash breaks.
The X11 OmniCyclone made Vacuum Wars’ October top 20 with a roller mop that scrubs and rinses itself, a ZeroTangle 3.0 brush and a bagless dock, so the running cost of dust bags simply goes away. Its PowerBoost charging tops up the battery during mop-washing breaks, about 6% in three minutes by Vacuum Wars’ count.
Bagless has a trade-off. Vacuum Wars’ three-month home test of the newer X12 OmniCyclone, which uses the same style of bagless dock, found it messier to live with than expected. If dust bothers you, a sealed bag is the cleaner way to empty a robot.
Ecovacs lists 19,500 Pa of suction with 38 CFM of airflow, a TruePass four-wheel system that crosses steps up to 0.9 inches and gaps up to 1.6 inches, and a Triple Lift system that raises the roller on carpet. The station hot-washes at up to 167°F, dries the roller, refills water and doses two cleaning solutions.
You’re tired of buying dock bags and most of your floors are hard.
Allergies are a concern. A bagged dock like the MOVA P10 Pro Ultra seals the dust away.

Best budget self-emptying robot
The affordable robot that handled thick carpet best in CNN’s testing.
Why it’s on this list: The longest rated bag life here, 150 days, on our budget pick.
CNN Underscored tested ten robots and found the D20 Pro Plus the best of its affordable group at getting across high-pile carpet, which is exactly where cheap robots usually bog down.
Treat the mop as a bonus. It drags a pad fed by a 350 ml tank, which keeps dust down on hard floors but won’t lift dried stains the way a mop-washing dock does. As a self-emptying vacuum at this price, it covers the basics well.
Dreame lists 13,000 Pa of Vormax suction, a HyperStream detangling DuoBrush, an extendable side brush for corners, a 500 ml onboard bin and a dock with a 5-liter bag rated for up to 150 days. It works with Alexa, Siri and Google Home, on 2.4 GHz Wi-Fi.
You want hands-off vacuuming on carpet and rugs for the least money.
You want real mopping. Step up to the MOVA P10 Pro Ultra, which washes its own mops.

Best overall
The most complete robot here: slim enough for low sofas, careful around clutter and excellent with pet hair.
Why it’s on this list: A full-service dock with about 100 days of dust capacity.
Vacuum Wars ranked the X60 Max Ultra Complete as its best overall robot vacuum from June through August, and it still sits near the top of the channel’s October list. The numbers explain why: a rare 100% on flattened pet hair, an 89% carpet deep-clean score, and 22 of 24 obstacles avoided with its binocular cameras.
Its real trick is height. At 3.13 inches with a retractable LiDAR, it reaches under sofas and beds that stop most robots, and it still climbed a 51 mm threshold in testing. The compromises are modest: about 950 square feet of coverage per charge and a small 235 ml onboard bin, so a large single-story home will see it pause to recharge.
Dreame’s listing fills in the daily details. The mop pads press down with 15 N at 230 RPM using 104°F water, the 10-in-1 dock washes and dries them and holds roughly 100 days of dust, and a dual-solution system doses detergent for you. It sets up on 2.4 GHz Wi-Fi only, so check that your router still broadcasts that band.
You have shedding pets, low furniture and a floor that’s rarely free of socks and cords.
The price stings. The Ecovacs T90 Pro Omni matched its 100% pet-hair score in testing, and Dreame’s X60 Ultra lists the same 3.13-inch robot with a simpler single-solution dock.

Best vacuum-only robot, no mop to manage
No water tanks, no pads, no bags: just a vacuum that empties itself.
Why it’s on this list: A 60-day bagless base on a vacuum-only robot.
Plenty of homes don’t need a mop at all, and every mop adds tanks to fill and pads to wash. The AI Ultra skips all of it. Vacuum Wars has reviewed Shark’s AI Ultra family, and TechGearLab’s ratings place it mid-pack: it earns a spot through simplicity, not record scores.
Shark’s Matrix Clean pattern sends it over the floor in a grid of overlapping passes for extra coverage on carpet, and the LiDAR map lets you send it to one room from the app or by voice.
Shark lists a bagless base that holds up to 60 days of debris, a self-cleaning brushroll designed to prevent hair wrap, up to 90 minutes of runtime with recharge and resume, and Alexa and Google Assistant support.
Your floors are mostly carpet, nobody wants to deal with mop pads, and you’d rather not buy bags.
You need careful avoidance of pet messes. Camera robots like the Dreame X60 Max are much more cautious.

Best Shark robot vacuum
Shark’s most hands-off robot, with a bagless base that also hot-washes the mop.
Why it’s on this list: A 60-day bagless bin plus a heated mop wash.
Tom’s Guide’s reviewer called it a premium, fully autonomous vacuum and mop and rated its vacuuming highly. The NeverTouch Pro base handles nearly all of the upkeep, and Shark is a brand you can find at most big US retailers when you need a part.
Two quirks from that review are worth knowing: the dock’s short power cord limits where it can go, and the robot occasionally lost track of where it was on the map. CNN Underscored also found Shark’s app experience a bit clunky.
Shark says the base washes the mop with 185°F water, dries it with 175°F air, empties debris into a 60-day bin and refills the robot’s water for up to 30 days. Dirt Detect boosts suction on dirtier patches, Edge Detect blasts air along baseboards, and the mop extends up to an inch for edge cleaning.
You want a familiar brand that’s sold almost everywhere, and no dust bags to buy.
Your only sensible dock spot is far from an outlet. Measure first; Tom’s Guide found the cord short.

Best value full-service dock
Most of a flagship’s daily routine, for far less than flagship money.
Why it’s on this list: A 3.2-liter bag rated for about 75 days and a mop-washing dock.
TechGearLab’s robot vacuum ratings name the P10 Pro Ultra the best pick for most people, and RTINGS has bought and reviewed it as well. It’s one of the least expensive robots here with a dock that washes and dries its own mops.
Expect fewer extras than the flagships. Its camera system recognizes about 70 kinds of objects, where Dreame’s newest robots list 280-plus, so a floor covered in toys and cables is a better job for the X60 Max.
MOVA lists 13,000 Pa of suction, a dock that washes the mops with 149°F water and dries them with hot air, a 3.2-liter bag good for about 75 days, and 4.5-liter clean and 4-liter dirty water tanks. The mops lift 10.5 mm on carpet, and the 5,200 mAh battery is rated for up to 2.5 hours.
You want a mop-washing dock and camera obstacle avoidance without spending flagship money.
You have heavy shedders and lots of rugs. The Dreame L60 Pro Ultra is the stronger carpet and pet-hair machine.

Best for sticky kitchens
A premium roller mop that pre-soaks stains before it scrubs them.
Why it’s on this list: Bagless with a pre-spray roller; the related X12’s dock got messy in a three-month test.
Vacuum Wars tested the closely related X12 OmniCyclone and counted it among the year’s best performers: a very high combined mopping score from its FocusJet pre-soak, 100% pet-hair pickup with no tangles, and 23 of 24 obstacles avoided. Its three-month home test was less glowing about the bagless dock, which got messy.
The X12S listing describes the same FocusJet pre-spray and a 10.6-inch OZMO Roller 3.0 fed by 32 water outlets, with a scraper pulling dirty water away. On carpet, Carpet Shield lifts the roller 0.59 inches and closes a cover over it, and PowerBoost PLUS restores up to 13% battery in a 3-minute wash. At 3.86 inches it stands taller than the slim Dreames.
Kitchens, kids and pets, and you want the best stain removal with no bags to buy.
Low furniture. At 3.86 inches it won’t fit where the X60 Max does.

Newest budget Dreame
A newer budget Dreame with more suction on paper and a 120-day bag.
Why it’s on this list: A sealed 4-liter bag rated for about 120 days; too new for independent tests.
Not yet independently tested.
This is a new listing without independent test results yet, so it sits here as an alternative rather than a pick. On paper it improves on the D20 Pro Plus with 20,000 Pa of suction and a sealed 4-liter bag rated for about 120 days.
Dreame lists LiDAR mapping, a main brush that removes hair as it cleans, an anti-tangle side brush and a simple vacuum-and-mop tank with adjustable water flow.
You want the newest budget Dreame and don’t need published tests yet.
You prefer proven results. The D20 Pro Plus has them.

Cheapest self-emptying Roomba
The cheapest way into a self-emptying, laser-mapped Roomba, with real limits.
Why it’s on this list: The cheapest self-emptying robot here; weak on pet hair in testing.
It gives you laser mapping and a dock that empties into a sealed bag for up to 75 days, at a price far below most self-emptying robots. Independent tests are unkind, though: Vacuum Wars measured just 29% pickup of flattened pet hair, heavy hair tangling and no obstacle avoidance, and RTINGS scored it 5.0 for pets.
At 4.1 inches tall in Vacuum Wars’ measurement, it won’t fit under many sofas either. iRobot says the bag traps 99% of allergens as small as 0.7 microns, and the robot can be started from its own buttons as well as the app or a voice assistant.
You have no pets, simple floors and the smallest budget for a self-emptying robot.
You have pets. With 29% pet-hair pickup in testing, the Dreame D20 Pro Plus is the better budget buy.

Bags cost a little and keep dust sealed when you empty them. Bagless bins cost nothing to refill but need rinsing, and Vacuum Wars found one messier than expected over three months.

Listings here range from 60 to 150 days. Pets, kids and larger homes shorten that a lot, so judge by your first month, not the box.
Self-emptying is the base layer. Mop docks add washing, drying, water refills and detergent; each adds convenience and something else to keep clean.
Short answers to what people ask most.
For most homes, yes. Emptying a robot’s small onboard bin every day is the chore that makes people give up on robots; a dock turns it into a monthly job.
Listings in our data claim 60 to 150 days. Pets and larger homes fill them faster.
Bagged if dust or allergies bother you; bagless if you’d rather not buy refills and don’t mind rinsing a bin.
Use bags made for your dock model so they seal. Third-party bags are fine if they list your exact dock.
Usually only if the maker sells a compatible dock for that exact model; most robots ship with or without one.
Briefly, yes. It runs a strong vacuum for a few seconds after each clean.
For no bags ever, the Ecovacs X11 OmniCyclone. For the longest time between bags on a budget, the D20 Pro Plus. And if you want the dock to do everything, the X60 Max Ultra Complete.
