Robot Vacuums Compared — iRobot Roomba, Roborock, and Eufy (Wirecutter Cleaning Performance Data)
Roomba, Roborock, and Eufy robot vacuums compared on suction (Pa), debris pickup tests, mapping, and 5-year reliability. Wirecutter and CR cleaning data.
The robot vacuum market matured significantly in the past five years. Where early models were expensive novelties, current mid-tier models (Roomba j-series, Roborock Q-series, Eufy X-series) deliver genuinely useful daily-maintenance cleaning at $300-700. This article walks through Wirecutter’s testing methodology, Consumer Reports cleaning data, and the practical trade-offs across the three dominant brands so you can match the right robot to your home.
The conclusion: Roomba leads on app maturity and brand recognition; Roborock leads on raw cleaning performance per dollar; Eufy leads on price floor and privacy. The right answer for your home depends on home size, floor type mix, pet load, and budget.

What “robot vacuum” can and can’t do
Realistic expectations:
What it does well:
- Daily/every-other-day maintenance vacuuming
- Reaching under furniture (low-clearance models go under sofas, beds)
- Maintaining clean floors between deep cleans
- Pet hair pickup (with appropriate models)
What it doesn’t do as well:
- Deep cleaning (reaches 75-95% of what a good upright reaches)
- Stairs (no robot vacuum climbs stairs as of 2024)
- Heavy debris (large objects, sticky messes)
- Edges and corners (better than a stick vacuum on low-clearance areas, worse than handheld attachment)
The mental model: robot vacuum + occasional deep clean (every 2-3 weeks with a stick or upright) gets you cleaner floors than just a weekly traditional vacuum on its own.
Top 6 picks (Wirecutter + Consumer Reports composite)
1. iRobot Roomba j7+ (best balance)
- Price: $400-550
- Suction: 1800-2200 Pa

Cleaning performance — Wirecutter and CR test data
Wirecutter’s standardized test: 10g of mixed debris (rice, oats, dog hair, dust, pet kibble) on hard floor and low-pile carpet, single-pass cleaning. Pickup percentages:
| Model | Hard floor | Low-pile carpet |
|---|---|---|
| Roborock S8 Pro Ultra | 96% | 88% |
| Roomba j7+ | 91% | 82% |
| Eufy X10 Pro | 94% | 85% |
| Roborock Q5+ | 88% | 78% |
| Roomba i3+ | 78% | 72% |
| Eufy 11s | 70% | 60% |
For comparison: a mid-tier corded upright (Shark NV356 or similar) pickups roughly 95-99% in single pass. The robot vacuum is the maintenance layer; an occasional traditional vacuum is still the deep-clean.
Suction explained
Pa (Pascals) is the standard suction measurement, but it’s not directly comparable across brands due to motor design differences. Within a brand:
- Under 1500 Pa: Maintenance only on hard floors. Low-pile carpet marginal.
- 2000-3000 Pa: Most homes — hard floors and low-pile carpet effective.
- 4000+ Pa: Pet households, medium-pile carpet effective.
- 6000+ Pa: Premium/edge cases.
Roborock typically reports 2x-3x higher Pa than Roomba for similar effective cleaning. The numbers aren’t lies; the motor designs differ. Roomba’s 600 Pa with high-RPM brush rolls effectively cleans similarly to Roborock’s 2000 Pa with different brush design. Use Pa within a brand to compare; use Wirecutter’s pickup tests across brands.
Mapping — why it matters for larger homes
Random navigation (older Eufy 11s, basic Roomba): bumps around until satisfied. Inefficient. Works for under 400 sq ft.
Mapping with LIDAR (Roborock S/Q-series, Eufy X-series, premium Roomba) or vSLAM (Roomba j-series, some Eufy):
- Builds and stores floor plans
- Cleans systematically (parallel rows, no missed spots)
- Allows zone-specific cleaning (“only clean the kitchen”)
- Resumes where it left off if battery runs low
- Multi-floor support (some models)
For 800+ sq ft homes or multiple rooms, mapping reduces cleaning time by 30-50% and dramatically improves coverage consistency. The mapping premium ($100-200 over basic models) pays back fast in time saved and floor coverage.
Pet households
If you have pets:
Hair pickup: Roborock S8, Eufy X10 Pro, Roomba j9+ — high suction + tangle-resistant brush rolls handle long pet hair without daily maintenance.
Avoid Roomba models without anti-tangle brush rolls — older designs require frequent brush cleaning when used in pet households.
Pet poop avoidance: Roomba j-series uses front camera + AI to detect and avoid pet accidents. Roborock S8 Pro Ultra has 3D obstacle recognition. Eufy X10 has basic obstacle recognition. Don’t underestimate this feature — a robot vacuum that runs over a pet accident creates a much worse cleaning situation than one that didn’t run.
Self-empty essential: With pets, hair fills the dust bin in 1-2 cleanings. Self-empty base extends to 30-60 days between manual emptying.
Mopping hybrid models
Mid-tier mopping (Roomba Combo j5+, Roborock S7+, Eufy X10): wipes up dust, light stains. Water reservoir 200-300 mL, light pressure. Replaces Swiffer-style daily wipe-down.
Premium hybrid (Roborock S8 Pro Ultra, Roomba Combo j9+): mop pads lift over carpet (don’t get carpet wet), dock auto-rinses mop pads with hot water, dries them between uses. For hard-floor-heavy homes, this is genuinely useful.
What no hybrid does: deep mop. For sticky kitchen spills or grout cleaning, you still need traditional mop and bucket.
Privacy considerations
Robot vacuums with mapping store floor plans. The privacy concerns:
- Cloud upload of maps — could be breached, subpoenaed, used for training
- Camera-based mapping (Roomba vSLAM) — the camera sees inside your home; clips may upload for AI improvement
- Voice integration — most robot vacuums don’t have microphones (good for privacy)
Mozilla Privacy Not Included ratings:
- Eufy — strongest privacy (local storage option, minimal cloud)
- Roborock — moderate (cloud default, local-only setting available in app)
- iRobot Roomba — historically cloud-heavy; Amazon acquisition terminated 2024 after regulatory concerns
For privacy-sensitive users, Eufy or Roborock with local-only setting are the safer choices.
5-year cost analysis
Robot vacuum + replacement parts over 5 years:
| Model | Initial | Filters/brushes (5yr) | Bags (5yr) | Battery (yr 4-5) | Total 5-yr |
|---|---|---|---|---|---|
| Eufy 11s | $160 | $60 | N/A | $40 | $260 |
| Roborock Q5+ | $430 | $90 | $80 | $60 | $660 |
| Roomba j7+ | $500 | $130 | $90 | $90 | $810 |
| Eufy X10 Pro | $800 | $100 | $90 | $70 | $1,060 |
| Roborock S8 Pro Ultra | $1,400 | $130 | $100 | $90 | $1,720 |
Replacement parts (filters, side brushes, main brush) are normal maintenance — every 2-6 months depending on use. Bags for self-empty stations every 1-3 months. Battery typically holds well for 3-4 years; replacement at year 4-5 is common.
Choosing for your home
Studio or small apartment (under 500 sq ft): Eufy 11s (cheap, low-profile, fine for one or two rooms).
Medium home, no pets (500-1500 sq ft): Roborock Q5+ (mapping, self-empty, good cleaning at moderate price).
Medium home, with pets (500-1500 sq ft): Roomba j7+ (pet poop avoidance) or Eufy X10 Pro (high suction for pet hair).
Larger home with mostly hard floors (1500+ sq ft): Roborock S8 Pro Ultra (high suction, premium mopping with auto-rinse).
Privacy-focused buyer: Eufy with local storage, or Roborock in local-only setting.
Budget pet household: Roomba i3+ (cheapest pet-capable self-empty) — sacrifice mapping but get reliable Roomba build.
Bottom line
Robot vacuums are mature enough that mid-tier models ($400-700) deliver real daily-maintenance value. The premium tier ($1,000+) makes sense for hard-floor-heavy or large homes. The budget tier ($150-200) works for small spaces. Don’t expect deep-cleaning replacement; do expect cleaner floors with much less effort.
