Which slim ninja wins — the stealthy RoboVac 11S that slips under couches or the Roomba 675 with suction like a tiny tornado — and which one will actually save you time (and dignity)?
A quick, friendly face‑off: the slim-and-stealthy eufy RoboVac 11S (Renewed) versus the classic, row-loving Roomba 675. We’ll compare fit, cleaning power, smarts, and upkeep so you can pick the right robot roommate, and maybe save your socks from mysterious disappearances.
Under-Furniture Champion
Excellent choice if you want a quiet, low-profile robot that actually gets under furniture and keeps floors tidy with minimal fuss. It favors simplicity over smart-home frills, delivering solid suction and long runtime without a complicated app.
App-Controlled Cleaner
A great option for users who want app control, voice commands, and reliable, methodical cleaning without spending a fortune on premium mapping. It balances effective cleaning and smart-home features, though it’s not the slimmest unit and requires standard upkeep.

Roomba 675 vs. Eufy 11S Slim: Quick Overview
Design & Fit: Slim Profile vs Classic Build
Size & Height
The eufy RoboVac 11S is built to disappear under furniture: 12.8″ diameter and just 2.85″ tall. The Roomba 675 is chunkier at 13.4″ diameter and 3.54″ tall — about 0.7″ taller. If you have very low-clearance sofas or TV stands, that extra height can mean the difference between a clean floor and a robot stuck under the couch telling you its life story.
eufy 11S — slim specifics
Lightweight and sleek: 5.73 lbs, 0.6 L dustbin, 100-minute run time, includes one side brush. Its low profile is the headline feature for tight gaps and under-bed runs.
Roomba 675 — classic build
A bit heavier at 6.77 lbs, same 0.6 L dustbin, ~90-minute runtime. The Roomba’s taller body houses dual multi-surface brushes and a dedicated side brush for edge pickup; it’s designed more for systematic, row-by-row cleaning than stealthy squeezes.
Dustbin, bumpers & brushes
Portability & storage
Measure doorways and under-furniture gaps before buying — a tape measure is your friend. The 11S stacks easier on a shelf thanks to its slim height; Roomba is a bit bulkier but still easy to carry by hand.
Cleaning Performance: Suction, Brushes, and Floor Types
Suction & brush design — specs vs reality
eufy advertises 1300Pa and a single central roller plus one side brush. In practice that 1300Pa gives confident pickup on surface dust and small debris while staying impressively quiet — like a vacuum in a library, but slightly more assertive.
The Roomba 675 leans on iRobot’s “Power-Lifting Suction” and a patented 3‑stage system with dual multi-surface brushes plus a side brush. It doesn’t publish Pa, but the combination lifts and moves larger debris more consistently, especially from carpet fibers.
Hard floors, low- & medium-pile carpets
Debris tests: rice, cereal, pet hair
Edges, corners, thresholds & heavy messes
Limitations: eufy’s quieter suction means slightly less raw pulling power on medium piles; Roomba’s taller body can miss under‑low furniture.
Feature Comparison Chart
Smart Features, Navigation & Controls
Navigation style: methodical vs. modest
Roomba 675: sensor-driven and methodical — it cleans in neat rows, uses bump and cliff sensors to avoid drops, and generally covers open rooms with a predictable pattern. No high-res mapping, but much less random wandering.
eufy 11S: simpler, low-tech navigation — edge-following and opportunistic spirals/random passes. It’s slim so it parks itself under low furniture your Roomba can only dream about, but it won’t map your house or plan a route.
Connectivity & scheduling
Virtual barriers / no‑go zones
Error handling & stuck recovery
Both use cliff and bumper sensors and will back away, try a different angle, and return to the dock when battery is low. Roomba’s app can alert you to persistent errors (e.g., “stuck on cords”), while eufy will silently stop and require a glance.
Day‑to‑day “smarts”
If “smarter” means app control, voice, and predictable coverage — Roomba. If it means plug‑and‑forget, quiet, and slipping under the couch — eufy.
Maintenance, Noise, Battery Life & Value
Runtime, charge time & real-world coverage
Noise: “super quiet” vs typical Roomba hum
eufy leans into “super quiet” marketing — in real rooms it’s noticeably gentler (think library-ish background). Roomba 675 is louder during strong suction cycles (more like casual conversation level). If you run overnight or work-from-home calls, eufy is the lower-profile roommate.
Filters, brushes & replacement costs
Bin emptying & maintenance cadence
Both have ~0.6 L bins. Expect emptying after every run in high-hair homes, every 2–3 runs for light dirt. Brush cleaning weekly; filter washing/replacing every 1–3 months depending on use.

Final Verdict — Which One Should You Buy?
The eufy 11S wins — slim, quiet, great value, ideal for tight spaces and light carpets.
Pick the Roomba 675 for steadier navigation, consistent row-by-row cleaning, and stronger brand support plus regular software updates. Quick buying tip: prioritize quiet for bedrooms, suction for pets, smart features for scheduling. Ready to tidy up today?
For folks debating: think about long-term costs (parts, replacements) and daily annoyances (noise, getting stuck).
I went with Roomba 675 because of pets and the slightly stronger pickup.
If I had mostly hardwood and kids napping, 11S would’ve been tempting though.
Exactly — choose the one that fits your routines, not just the higher number on paper.
Excellent pragmatic lens, Rachel. User lifestyle often trumps spec sheets.
I appreciate this kind of real-world framing. Specs are one thing; living with the device is another.
I had both at different times. Short summary: RoboVac 11S = quieter, slimmer, cheaper (esp. renewed) and great on hardwood.
Roomba 675 = stronger lift suction, better on pet hair, smarter navigation (and Alexa support).
If I had to pick one for a small apartment with a dog, I’d go 675.
If your priority is stealth and getting under low furniture, choose the 11S.
Not complicated but depends on pet hair vs furniture clearance. 😊
Agreed. My Roomba 675 picks up my Chihuahua’s fur much better than the 11S did.
Great summary, Sophia — that mirrors the article’s conclusions. Pet owners often prefer Roomba for the suction and lifting tech.
Do you know if the 675’s filters are easy to replace? I hate hard-to-clean dust canisters.
Confirmed — Roomba filters and brushes are widely available. If you have allergies, look for HEPA-compatible replacements.
Maya — yes, replacement parts are easy to find and the filter+tank are straightforward to clean. Roomba’s design is pretty user-friendly.
Not gonna lie — I bought the cheaper renewed 11S, and it’s been fine for 9 months. If you can deal with occasional jams and shorter battery life, it’s a bargain.
Anyone tried scheduling on the Roomba with Alexa? I set it up and it worked once, then Alexa got confused and scheduled nothing for the week 😂
I had the same issue — relinking the skill fixed it for me. Also check for app updates.
Sometimes voice commands behave differently than app schedules. I use the app for reliability.
Heh, smart home quirks are real. Make sure the Roomba and Alexa skills are linked and that both devices use the same account region/timezone.
Got the 11S renewed for cheap. Works fine but battery life felt shorter than expected after a year. Might be the refurb battery.
Little anecdote: I loaned my mom a 675 and she called it ‘the little row guy’ because she loved watching the neat pattern. She swears it cleaned better than a deep clean service she paid for lol.
Not scientific, but it convinced her to buy one.
Funny how aesthetics of cleaning patterns can influence perception of effectiveness.
My grandma calls her robot ‘the sweepy’. Pet names for gadgets are underrated.
Ha! ‘Little row guy’ — that’s delightful. Sometimes the pattern-based cleaning feels more satisfying.
Stories like that sell me — when people actually notice a difference, it’s meaningful.
Question: the article mentions 1300Pa for 11S. How does that compare to Roomba’s ‘power-lifting suction’? Are they measuring the same thing?
Good question. Manufacturers advertise different metrics; ‘Pa’ is a suction pressure unit, while iRobot often uses marketing terms like ‘power-lifting suction’ without a standardized Pa number. In practice, Roomba’s cleaning tech (brushes + airflow) often leads to better pickup even if raw Pa is lower.
So basically raw numbers don’t tell the whole story. Performance and brush design matter.
I bounce between these two in reviews but here are some practical tips:
– If you want voice control and routines, Roomba 675 plus Alexa is handy.
– If you care about noise level (baby sleeping, etc.), 11S is quieter.
– Both self-charge, but Roomba resumes cleaning in rows which feels more thorough.
Hope that helps for anyone deciding!
Good point Ethan — I replace brushes on my Roomba every 6-9 months, so cost adds up.
Also add: check replacement part prices. Some older models have cheaper parts, which matters long term.
Nice practical breakdown, Olivia — that’s exactly the trade-off many users face.
Thanks for this — I’m leaning toward the 11S because my kid naps all day, haha.
Roomba 675’s smart navigation is surprisingly satisfying to watch it clean in neat rows. Kind of therapeutic lol.
Totally — Roombas with row-based navigation feel more ‘systematic’ than random bots. 675 does a decent job especially on mixed-floor homes.
