2 independent reviewsRead the findings →SwitchBot's very small robot vacuum, with one of the tiniest self-emptying docks around. It suits cramped homes where the mess is mostly dust and hair. Its 'mop' is just a wet wipe, and its vacuuming and mapping are inconsistent.

Feedback
What reviewers found
Two home tests, and they don't agree. TechRadar used it as their main vacuum for a fortnight and found it fast, confident and good at pickup. Tom's Guide needed about four mapping attempts and watched it crush cereal rather than collect it. Both loved the tiny dock and big dust bag, and both dismissed the wet-wipe mop. The gap looks partly down to the mess each one used, so think about what usually ends up on your floor before you buy.
TechRadar, hands-on, 2 weeks at home, Sept 2025 · Tom's Guide, hands-on, Nov 2025
Hard floors
Mixed resultsFine dust and grit suit it, larger crumbs don't. TechRadar found it picked up plenty of dust even on a low setting, but Tom's Guide saw it crush most of its cereal on hardwood rather than collect it, though kitty litter came up completely.
Carpet and rugs
Mixed resultsTechRadar saw most oats cleared from carpet in one pass. Tom's Guide found cereal too big for the narrow brush opening, so only a small share came up from carpet.
Pet hair
Not enough evidenceOnly Tom's Guide tested pet hair, finding it picked up most but not all, and hair needed clearing from the brush now and then.
Mopping
Reviewers found problemsThe mop is a disposable wet wipe. TechRadar saw soy sauce smeared across tiles and dried ketchup untouched, and Tom's Guide said it isn't really a mop at all.
Navigation and obstacles
Mixed resultsTechRadar found it fast and confident around furniture, though it bumped the dog and pushed a water bowl. Tom's Guide's first map was almost entirely wrong and took about four attempts to get right.
Dock and upkeep
Reviewers rate it highlyBoth testers liked the tiny dock. TechRadar kept it under a bed, and Tom's Guide expected its 4-litre bag to last about two months, leaving little to do beyond clearing the brush.
App and software
Mixed resultsTechRadar found the app workable but with some illogical quirks. Tom's Guide liked its maintenance reminders, but found you can't add missed areas to a bad map by hand, only remap.
Noise
Mixed resultsQuiet cleaning, noisy emptying. Tom's Guide measured about 50dB while cleaning, and TechRadar also found it fairly quiet, but both found the auto-empty cycle loud; you can make it run less often.
Reliability and support
Not enough evidenceNone of the reviews we use ran it long-term or judged SwitchBot's support yet.
Value
Mixed resultsBuy it on sale. TechRadar felt you pay a premium for the small size at full price, and Tom's Guide advised against paying full price given how often it's discounted.
Verdicts come from independent, hands-on, finished reviews. An area needs at least two of them before we say more than “Not enough evidence”. We don't score robots ourselves. How this works
Tiny robot, tiny dock
TechRadar measured it at 24.8cm across and liked how it squeezed into narrow spots. The dock was small enough to live under their bed, yet it holds a 4-litre bag. Tom's Guide found the dock a little smaller than the K10+ Pro's and liked its wooden top, but it still needs a wall behind it and a clear runway in front. The robot itself is normal height, so the win is width, not getting under low furniture.
Pickup depends on the mess
TechRadar saw most oats cleared from carpet in one pass, and a stubborn tea spill was mostly gone after a second run on full power. Tom's Guide got very different results with Cheerios: only 40% came up from hardwood and 30% from carpet, because the cereal couldn't fit through the narrow brush opening and got crushed instead. Kitty litter came up completely, and pet hair scored 65 to 70%. Fine dust and grit suit it; larger crumbs, cereal or kibble don't.
Mapping went very differently
TechRadar found it fast and confident around permanent furniture. Tom's Guide's first map was almost entirely wrong: the robot circled one small spot, reported invalid map data and took about four attempts to get it right. You can't add missing areas by hand, so the only fix is another mapping run. Nobody has shown why the two homes differ. Watch the first map closely and redo it straight away if it looks off.
The mop is a wet wipe
Mopping means clipping a disposable wet wipe onto a plate under the robot. TechRadar found it fiddly to fit, and in their test soy sauce got smeared across the tiles while dried ketchup didn't budge. Tom's Guide said it's not really a mop at all. TechRadar also found the dock can't sit inside a no-mop zone, which limits where it can go if you use the wipe. Treat the K11+ as a vacuum and keep your usual mop.
Quiet cleaning, noisy emptying
Tom's Guide measured about 50dB while it cleaned, quieter than the K10+ Pro, but found the emptying cycle unpleasant. TechRadar agreed the emptying is loud and suggested making it happen less often in the app. Battery life wasn't a problem in either home, and Tom's Guide never saw it run out mid-clean in a compact flat. Expect to pull hair off the brush now and then, as Tom's Guide did.
Our take
Should you buy the K11+?
Best for: Small homes with low furniture and little space for a dock. Skip it if: You want it to scrub floors or wash its own mop.
buy the K11+ for a small, cramped home where there is nowhere to put a normal dock and the mess is mostly dust and hair. If you can empty the bin yourself, TechRadar points out the Roborock Q7 M5 costs less and mops far better.
The K11+ is SwitchBot's replacement for the K10+ Pro. The robot is about 25cm across, so it fits gaps between furniture that normal-sized robots cannot, though it is a normal height and will not slide under a low sofa. Its self-emptying dock is one of the smallest around yet still holds a big dust bag. The mop is a disposable wet wipe on a plate.
The two tests disagree. TechRadar used it as its main vacuum for a fortnight and found it fast and confident around furniture, with most oats cleared from carpet in one pass. Tom's Guide's first map was almost entirely wrong and took about four attempts to get right, and it saw most of its cereal crushed rather than collected because the pieces would not fit through the narrow brush opening, though kitty litter came up completely. Both loved the tiny dock, which TechRadar kept under a bed, and both found the emptying cycle loud. Neither thought the wipe was worth fitting: TechRadar saw soy sauce smeared across tiles, and Tom's Guide said it is not really a mop at all. Both advise buying it on sale rather than at full price.
Before you buy
The questions people ask about this one
Does it fit under low furniture?
Probably not under very low pieces. It's narrow but about as tall as most robots: 98.5mm on the specifications, and TechRadar measured 9.2cm. It's built to get between furniture, not under it. Measure your lowest gap before you buy.
Will it avoid cables and pet mess?
Not reliably. TechRadar saw it drive into the dog, push a water bowl across the room and suck up a ribbon standing in for a cable. It hit a shoe once but went round it the next time. Tidy the floor before each run.
Is the mop worth using?
No. It's a disposable wet wipe that the robot drags along, and TechRadar found it smeared soy sauce and left dried ketchup alone. Tom's Guide agreed it isn't a real mop. Buy something with spinning pads or a roller if mopping matters.
How often do I have to empty anything?
Rarely. the specifications claims the dock's 4-litre bag lasts up to 90 days, and Tom's Guide estimated about two months. You'll still need to clear hair from the brush from time to time; the app reminds you when parts need attention.
How big is the dock, and is it loud?
Tiny: about 24 × 18 × 25cm by TechRadar's measurement, small enough for under a bed. The emptying cycle is loud, and Tom's Guide found it unpleasant, but you can reduce how often it runs.
Does it work with Apple Home?
Yes. It supports Matter, so it can be controlled from Apple Home, Alexa or Google Home without an extra hub, per the specifications. TechRadar lists the same Matter support. You still use the SwitchBot app for maps and settings.
Alternatives
Other robot vacuums to compare.
Q7 M5 / M5+
Why consider it: Testers found good pickup of debris and hair, with a compact charging dock.
The compromise: There's no self-emptying, and it needs help around cables, rugs and small clutter.
RV20 Max Plus
Why consider it: Mapped vacuuming and automatic emptying in a fairly compact package.
The compromise: Its simple mop is a light wipe, and it gets caught on low furniture and loose objects.
Roomba Mini Robot Vacuum & Mop + AutoEmpty
Why consider it: Its small size and useful everyday pickup suit compact homes.
The compromise: The mop is a basic wipe, carpet results are weaker and the app dropped out in one test.
