The quick verdict: eufy wins on value — you get more suction and longer battery life per dollar, and models like the RoboVac 11S MAX clean surprisingly well for under $250. iRobot wins on smarts and ecosystem: the Roomba 694 is the best-selling budget robot vacuum in America for a reason, and stepping up to the self-emptying i3+ EVO gets you smart mapping and 60 days of hands-free cleaning. Choose eufy to save money; choose iRobot for the app, mapping, and the Roomba name your smart home already knows.
Brand Overview: eufy
eufy is Anker’s smart-home brand, and it brought Anker’s playbook — solid hardware, aggressive pricing, no frills — to robot vacuums. The RoboVac line built its reputation on slim, quiet budget bots: the 11S series became one of the best-selling robot vacuums on Amazon with nearly 60,000 ratings, thanks to 2000Pa suction and a 2.85-inch profile that slides under furniture taller robots can’t reach.
eufy’s philosophy is simple: spend on the cleaning hardware, skip the expensive navigation. Most eufy bots use bounce or gyro navigation rather than LiDAR, which keeps prices low but means no room mapping on budget models. Higher-end models like the X8 series and the Omni lineup add LiDAR and self-emptying to compete with iRobot’s flagships.
Brand Overview: iRobot
iRobot invented the robot vacuum category with the Roomba in 2002 and still defines it — “Roomba” is practically a generic term. The brand’s strength is software: iRobot OS, Imprint Smart Mapping, Dirt Detect sensors that focus on dirty spots, and the best third-party integration in the business (Alexa, Google, Siri, and IFTTT all play nicely with Roombas).
iRobot’s lineup runs from the budget 600 series (the Roomba 694 is the perennial bestseller) through the mid-range i3 EVO with smart mapping, to the j-series flagships with obstacle avoidance and self-emptying Clean Bases. The catch: you pay the Roomba premium — an iRobot with the same raw specs as a eufy typically costs $50–150 more. iRobot also filed for Chapter 11 bankruptcy protection in late 2025, though the company continues to operate and support its products.

Product Spotlights
eufy BoostIQ RoboVac 11S MAX — Best Budget Pick
The 11S MAX is the robot vacuum that proved you don’t need to spend $400 for clean floors. Its 2000Pa suction handles hard floors and low-pile carpet well, the 2.85-inch body fits under beds and sofas, and it runs for up to 100 minutes at a whisper-quiet 55 dB. The tradeoff is deliberate: no WiFi, no app, no mapping — just a remote control. If you want a set-it-and-forget-it daily cleaner without smart-home fuss, this is the value king.
Pros:
- Excellent suction (2000Pa) for the price
- Ultra-slim 2.85″ profile reaches under low furniture
- Very quiet at ~55 dB
Cons:
- No WiFi, app, or voice control — remote only
- Random bounce navigation, no mapping or room selection
eufy BoostIQ RoboVac 15C Max — Best Connected Budget Bot
The 15C Max takes everything good about the 11S MAX and adds the smarts people actually want: WiFi, the eufyHome app for scheduling, and Alexa/Google voice control. Suction stays at a strong 2000Pa with BoostIQ auto-adjustment, runtime is up to 100 minutes in standard mode, and it keeps the same slim 2.85-inch profile. This is the eufy to buy if the 11S MAX’s lack of an app is a dealbreaker.
Pros:
- 2000Pa suction plus app, scheduling, and voice control
- BoostIQ automatically ramps suction on carpet
- Usually priced well under comparable Roombas
Cons:
- Still random navigation — no mapping or keep-out zones
- Max mode drops runtime to around 40 minutes
iRobot Roomba 694 — Best-Selling Budget Roomba
The 694 is the robot vacuum most Americans actually own. You get WiFi, the polished iRobot Home app with personalized cleaning suggestions, Alexa and Google integration, and the 3-stage cleaning system with dual multi-surface brushes — the brush design iRobot is famous for. Navigation is old-school bump-and-clean with no mapping, and at 3.54 inches tall it won’t fit under the lowest furniture. But for a first robot vacuum, the combination of brand trust, app quality, and parts availability is unmatched. For our detailed breakdown, see our eufy RoboVac 11S review alongside this model’s specs.
Pros:
- Excellent iRobot Home app with smart scheduling
- Dual multi-surface brushes handle pet hair well
- Huge parts and accessory ecosystem
Cons:
- No mapping — cleans in a bump pattern
- Taller body (3.54″) misses low-clearance furniture
iRobot Roomba i3+ EVO — Best Mid-Range Self-Emptying Pick
The i3+ EVO is where iRobot pulls ahead of eufy decisively. Imprint Smart Mapping learns your floor plan room by room so you can send it to the kitchen with a voice command. The Clean Base empties the bin into a bag that holds up to 60 days of dirt. The Premium 3-Stage Cleaning System delivers 10x the suction of the 600 series. Battery life is shorter (75 minutes) because the smarter navigation cleans more efficiently in less time.
Pros:
- Real smart mapping with room-by-room cleaning
- Self-emptying base holds 60 days of debris
- Excellent pet hair pickup with dual rubber brushes
Cons:
- Premium price over eufy equivalents
- 75-minute runtime is shortest in this group
Who Wins Each Category?
Budget value: eufy. The 11S MAX matches or beats the Roomba 694 on suction and runtime for less money — you’re trading the app for raw cleaning power per dollar.
App and smart features: iRobot, easily. The iRobot Home app is the best in the business, and even the budget 694 offers scheduling and voice control the 11S MAX lacks.
Navigation and mapping: iRobot. The i3+ EVO’s Imprint Smart Mapping is generations ahead of eufy’s budget bounce navigation. (eufy’s LiDAR models like the X8 close the gap, but cost more.)
Pet hair: iRobot’s dual multi-surface brushes are the gold standard for pet hair, though eufy’s 2000Pa suction holds its own on hard floors. For heavy shedders, the i3+ EVO with self-emptying is the better system.
Noise: eufy. The 11S MAX at ~55 dB is noticeably quieter than most Roombas — a real factor if you run it while working from home.
Ecosystem and support: iRobot. More parts, more accessories, more third-party integrations, and two decades of brand trust.
Final Verdict
Buy eufy if you want the most cleaning power for the least money and don’t care about apps or mapping. The 11S MAX (or the 15C Max if you want WiFi) is the smart buy under $250.
Buy iRobot if you want the best app experience, real room mapping, and a self-emptying system. The Roomba 694 is the safe first-robot-vacuum pick, and the i3+ EVO is the mid-range sweet spot.

FAQ
Is eufy as good as Roomba?
For raw cleaning on hard floors and low-pile carpet, yes — eufy’s 2000Pa budget bots match or beat the Roomba 694. Roomba pulls ahead on app quality, navigation, and smart mapping. Think of eufy as the value play and iRobot as the smart play.
Which eufy is comparable to the Roomba 694?
The eufy RoboVac 15C Max is the closest match: similar price tier, 2000Pa suction, WiFi and app control, and voice assistant support. The 11S MAX is cheaper but lacks the app entirely.
Do eufy robot vacuums map your home?
Budget eufy models (11S, 15C) use random bounce navigation with no mapping. eufy’s higher-end models with LiDAR — like the X8 series — do build real maps with room selection, comparable to iRobot’s Imprint Smart Mapping.
Is iRobot still a good brand after bankruptcy?
iRobot filed for Chapter 11 in late 2025 but continues operating, selling, and supporting Roombas. Replacement parts remain widely available on Amazon. It’s a fair question to ask, but there’s no current sign of support disappearing.
Which robot vacuum is quietest?
The eufy RoboVac 11S MAX, at around 55 dB — roughly the volume of a microwave. Most Roombas run noticeably louder, especially on carpet with BoostIQ-equivalent modes engaged.
Should I get a self-emptying robot vacuum?
If anyone in the house has allergies or you hate emptying dustbins, yes — the i3+ EVO’s 60-day Clean Base is genuinely life-changing. It’s the single biggest quality-of-life upgrade in robot vacuums. See our iRobot vs eufy brand breakdown above for how the two brands’ self-emptying systems compare.
