Compare Roborock S8 + Robot Vacuum vs iRobot Roomba Combo i5 Robot Vacuum

Setup, app control, room selection, scheduling, and routine operation are repeatedly described as simple. The product is largely hands-off once maps and routines are configured.

Ease of use was very strong overall, from simple mapping and maintenance cleaning to quick room cleaning and few missed spots.

Automatic mop lifting is highly useful for mixed floors and protects most rugs during combined runs. Its roughly 0.2-inch lift is smaller than some premium rivals and may be insufficient for thick carpet.

Mop lifting was a weakness because one reviewer noted the i5 is not smart enough to avoid mopping rugs.

The dock is a standard premium-robot size, but one reviewer found it light enough to slide around too easily and wanted a more stable base.

Storage footprint feedback was positive because reviewers liked the sleek base and the ability to keep the robot out of sight.

Runtime is ample for large routine jobs, with reports ranging from roughly 90 minutes at maximum power to 180 minutes in quiet mode. Recharge-and-resume extends coverage further.

Runtime was mixed to weak: one review found it below average and another said double-pass cleaning drained the battery quickly.

The glossy white finish developed noticeable scratches after about six months, although the robot still looked generally presentable.

Surface safety feedback was positive, with reviewers saying it was not damaging surfaces and varied carpet line directions to avoid harm.

The S8+ reliably recognizes furniture, shoes, cords, toys, and pets and navigates well in darkness. It is not flawless with tiny pet waste or loose floor clutter, so clearing hazards remains wise.

Obstacle avoidance was mixed: some reviewers saw bumping, while another praised slowing before contact.

Carpet sensing and automatic mop lifting make mixed hard-floor and rug runs convenient. Very thick rugs may still contact the modestly raised mop pad.

Rug handling was mixed: it handled tassels and carpets well while vacuuming, but mopping lacks rug-aware avoidance.

The robot itself handles many everyday particles well, but the dock can struggle to evacuate bulky mixtures such as rice and peas. Large litter spills may require manual emptying.

Large debris handling was positive, with a reviewer reporting that larger objects could be picked up alongside fine dust and dirt.

The S8+ handles carpets and hard floors in one routine and stores multiple maps, but carrying it between stories limits truly whole-home automation.

Versatility was a major strength, with reviewers praising mixed-floor suitability and the convenience of vacuuming and mopping at the same time.

Auto-emptying keeps routine dust handling contained and greatly reduces contact with the onboard bin. Bulky debris can still remain behind and require manual emptying.

Emptying and mess control was easy and low-friction, with one-handed emptying and simple lever-based bin removal.

The dual rollers and strong suction remove carpet hair very effectively, with reviewers reporting less residue than competing robots.

Carpet hair pickup was rated positively through pet-hair performance and the cleaning system's carpet effectiveness.

Pet and human hair are removed efficiently from hard floors and deposited in the bin without frequent roller stops.

Hard-floor hair pickup evidence was positive, especially around pet and human hair in mixed-floor homes.

The package includes the core setup tools, spare dust bag, and mopping hardware needed to start cleaning. Reviewers appreciated practical touches such as the included screwdriver and replacement bag.

Accessory feedback was limited but positive, with one reviewer appreciating the included extra replacement filter.

The app-based child lock is a practical family feature that disables the robot's physical controls and prevents accidental starts.

Child and pet lock was positively received as useful for homes with kids or pets bumping buttons.

The child lock is a useful family safeguard that prevents children from starting or changing the robot through its physical buttons.

Kid-friendliness was supported by one reviewer who said it made life easier in a home with a toddler.

The mop is designed around water rather than a supplied cleaning solution. Reviewers who prefer detergent saw this as a limitation on stain-fighting power.

Liquid-system feedback was mixed: reviewers appreciated simple water or solution use, but one warned excess solution could leak onto floors.

Pet owners benefit from strong hair pickup, tangle-resistant rollers, and generally good navigation around animals. The robot can still miss very small pet waste and may struggle when large litter spills reach the auto-empty path.

Pet-related feedback was mostly positive for pet hair and hair-tangle resistance, though one reviewer noted pet-waste avoidance is better on the j9 line.

Mapping is fast, accurate, and highly editable, with 2D/3D views, room divisions, routes, and no-go zones. Navigation remains reliable even in darkness, though one test rated it slightly below the older S7 MaxV.

Mapping and path efficiency were standout strengths, with reviewers praising accurate mapping, room-by-room control, rows, and simultaneous mapping while vacuuming.

Reviewers find the robot confident around chairs, furniture legs, thresholds, and tight routes, with few rescues needed. Loose floor clutter remains the main handling risk.

Navigation and handling were praised across several reviews for methodical movement, accurate furniture navigation, and slowing down before obstacles.

Dual rollers and extensive software controls feel advanced, but some hardware choices are conservative or simplified. Reviewers noted that rival models may offer cameras, taller mop lift, or more automated docks.

Innovation feedback was mixed to negative because reviewers saw missing advanced features and little hardware upgrade versus related models.

Detachable roller ends make wrapped-hair removal and routine brush maintenance straightforward.

Tool and bin changes were described as simple, with the mop pad staying attached well and one reviewer saying the bin could be reinserted almost blindfolded.

Light mopping can finish cleanly, but high water settings or a dirty pad may leave sticky areas, smears, or streaks. Extra passes and pad rinsing improve the result.

Streaking was noted as a mild mopping issue in one hands-on hard-floor test.

The 300ml tank is adequate for many apartments and covered nearly 1,000 square feet in one test, but larger homes may run it dry. Short runs may also benefit from pre-wetting the mop pad.

Water tank feedback was modest, with one reviewer saying the tank system was not huge.

The dock bag commonly lasts around seven weeks, and one long-term user reached roughly six months before it was about 70 percent full. Replacement bags add an ongoing cost, but emptying frequency is low.

The bin was praised as easy to remove and empty, with reviewers noting a sizable container and one-handed emptying.

Daily work is low because the robot empties itself and resists tangles. Owners still need to wash pads, refill water, clean sensors and rollers, and replace bags and filters.

Maintenance was mixed: washable pads and hair-checking were manageable, but one reviewer stressed pre-run tidying and routine upkeep.

The consensus is strongly positive: reviewers see the S8+ as a reliable, highly capable daily cleaner. Praise is tempered by its high price, imperfect deep mopping, and loud emptying cycle.

Overall opinion was broadly favorable, including top-list praise, high-rated robovac language, repeated recommendations, and a 4.4-star owner-style rating.

LiDAR mapping, obstacle detection, no-go zones, and good threshold climbing keep rescues uncommon. Loose socks, wires, and unusually small hazards can still stop or confuse it.

Stuck resistance was strong in hands-on reports, especially around rug tassels and during longer whole-room jobs.

Tangle resistance is one of the clearest strengths. Hair mainly collects at removable roller ends rather than wrapping tightly around bristles.

Hair-wrap resistance was one of the strongest areas, with reviewers praising painless roller hair removal and anti-tangling performance.

Fine-dust and sand pickup on hard floors is consistently strong, reaching 99 percent in one test. Some controlled edge tests still left a small amount behind.

Hard-floor fine dust pickup was praised, including top bare-floor marks and visible fine dirt and dust in the bin.

The sub-four-inch body and spring-loaded LiDAR housing help the robot travel under lower furniture with less risk of becoming trapped.

Under-furniture pickup was a strength, with reviewers praising table, entertainment-center, and low-profile under-bed access.

On suitable hard floors, reviewers observed a visibly clean, shiny finish with little manual effort.

Floor shine was described as a light-touch benefit when using water, but not as a deep-cleaning result.

The robot itself is usually considered quiet, with some reviewers calling it quieter than comparable flagships. Maximum suction and mopping can become noticeably louder.

Noise feedback was mixed: one review found it typical for a robovac and another valued shorter run time, but several users called it noisy or very loud on hard floors.

The side brush reaches many corners and hard-to-access spots well, but the round mop body cannot fully scrub tight corner spills.

Corner cleaning was supported by hands-on mopping/cleaning coverage where the robot avoided missing areas.

The S8+ generally outperforms many hybrids in suction, edge cleaning, hair handling, and mapping. Some tests found the S7 MaxV stronger on first-pass cleaning or object recognition, while premium rivals offer taller mop lift or fuller dock automation.

Comparative performance was favorable against the 694 but less compelling as an upgrade over i3-class hardware.

Sonic mopping is better than most basic drag-pad robots and works well on light grime and everyday kitchen messes. Sticky stains, narrow edges, and neglected spills still need repeated runs or a manual mop.

Mopping was mixed: convenient and useful for maintenance, but repeatedly described as basic, surface-level, or short of a deep mop.

Scheduled vacuuming, mopping, mapping, and auto-emptying save substantial time and keep floors consistently presentable. Most manual work is limited to mop care, water, consumables, and occasional deep cleaning.

Overall cleaning convenience was praised for reducing effort, helping maintain the home, and making day-to-day life easier.

Several reviewers found edge pickup unusually strong for a round robot, with excellent cereal and dust collection. More demanding tests still left narrow strips or small debris beside baseboards.

Edge and baseboard cleaning was praised, including Consumer Reports-style edge performance and hands-on edge coverage.

Reviewers consistently praise the strong everyday suction, especially on sand, hair, and routine debris. One controlled test found the advertised 6,000 Pa did not translate into strong deep-groove extraction.

Reviewers consistently rated vacuum pickup highly, citing strong suction, good vacuuming results, a 90/100 deep-cleaning score, and carpet suction that helped the rollers clean effectively.

The wall sensor keeps the robot tracking closely and parallel to baseboards, supporting orderly edge coverage.

Edge-following accuracy was praised through straight-line cleaning and careful route consistency.

The Roborock app is one of the product's clearest strengths, offering detailed maps, room routines, schedules, no-go zones, carpet settings, and remote status. Reviewers found the automation powerful without being difficult to use.

Smart features and app control were widely praised for scheduling, room control, voice control, geofencing, and a simple app, but reviewers noted missing AI detection.

The app is generally clear and highly customizable, with room, zone, suction, mop, and map controls. Auto-empty scheduling is less flexible than some users would like.

Controls and UI were generally easy to use, though one reviewer found the feature set basic and another wanted more options.

Most reviewers consider the S8+ expensive, especially without a fully self-washing dock. Its strong vacuuming and convenience can justify the cost for larger mixed-floor homes, but smaller or budget-focused households may find it excessive.

Value was repeatedly praised at its sale or category price, though one reviewer noted the non-plus model lacks self-emptying at the same general market tier.

Dock assembly is minor, and QR-code app setup and mapping usually take only a few minutes. Reviewers repeatedly describe the process as quick and painless.

Setup was mostly easy or a breeze, with one unboxing reviewer adding that the initial setup was a little slow.

The robot usually returns and empties reliably, and the bag lasts for weeks. The dock handles dust, sand, flakes, and hair well but may leave bulky debris in the onboard bin.

Docking reliability was praised by one long-use reviewer who said the robot finished jobs and returned to the dock.

A long-term owner reported no operational issues, and reviewers generally found daily navigation, docking, and scheduled cleaning dependable.

Reliability was praised by one long-use reviewer who said the robot consistently finished jobs and returned to the dock.

The dual rubber DuoRoller head is a standout strength, combining strong debris agitation with much less hair tangling than bristled designs.

The dual-roller floorhead drew positive carpet feedback, especially for making carpet look clean and brushed.

Reviewers like the sleek, modern appearance, matte details, and choice of colors. The glossy white top can accumulate visible scratches over time.

Design impressions were positive, with reviewers calling the robot attractive, handsome, and sleek.

Materials, fit, rollers, and dock construction are widely praised as solid and premium. Long-term use showed limited functional wear despite some cosmetic marks.

Build quality was praised directly as super solid, with a durable-looking body after use.

After six months of daily use, the robot, rollers, and underside remained in good working condition. Cosmetic scratching was more noticeable than functional wear.

Durability evidence was positive after use, with one reviewer noting the robot avoided beating itself up and still looked nearly new.

At under four inches tall, the robot can reach beneath much furniture while the movable LiDAR cap reduces snagging risk.

Low-profile design was praised for being easy to hide and for fitting under tables, furniture, and beds.

Battery endurance is strong, and the robot automatically returns, recharges, and resumes unfinished cleaning. Off-peak and faster-charging options add flexibility.

Charging behavior was positive because the robot can return home, recharge, and continue cleaning.

The S8+ cleans thicker carpet well, lifting hair and heavier dirt with its dual rollers. Deep debris can remain in dense fibers, so high-pile rugs may still need an occasional full-size vacuum pass.

Low-pile carpet maintenance is generally excellent, with strong sand and hair collection. One demanding multi-pass test reached about 90 percent and still left some edge debris.

Medium-pile carpet surfaces clean well, but one detailed test found dirt remaining deeper in the fibers. It is better for maintenance cleaning than deep extraction.

The dual rubber rollers sharply reduce hair clogs and redepositing compared with bristled rollers. Reviewers rarely needed to stop a run for detangling.

Cord management was criticized because the dock cord had no tidy routing.

A detailed suction test found weak extraction from deeper floor gaps, with debris removed only from very shallow grooves.

The sonic mop handles light dried food, coffee, ketchup, and juice better than many robot mops. Tough sticky messes can require repeated passes, pad rinsing, or a manual mop.

Off-peak charging is a useful app option for shifting electricity use to cheaper hours, and faster charging helps reduce downtime.

The bagged dock and HEPA filtration keep routine debris contained and suit allergy-conscious or pet-owning homes. Washable filters also help extend service life.

Oatmeal and other routine larger debris were collected very effectively on hard floors. Results are strongest during normal pickup; the auto-empty dock is less reliable with bulky mixed debris.

Frequent automated cleaning helped one allergy sufferer keep floors cleaner and reduce exposure to accumulated irritants.

Heavy-duty suitability was limited, with reviewers saying it should not be relied on for heavy messes or solid deep cleaning.

Single-level apartments and smaller homes are especially well suited because the robot can cover the space without being carried between floors. The premium price may still be overkill for very small areas.

Surface safety with attachments was positive where reviewers said the robot's carpet-line pattern helped avoid harm.

Auto-emptying is the most consistent noise complaint, with one test measuring around 80 dB. The burst is short but can be startling or annoying if triggered after every room.

The maintenance counter helps owners track filter life and decide when to wash or replace components.

Replacement dock bags, brushes, filters, and mop pads create recurring costs. Reviewers viewed those expenses as the price of hands-off convenience rather than a deal-breaker.

The S8+ cannot clean stairs and must be carried between levels, so multi-story homes still need manual vacuuming and relocation.

Software support was framed positively as a way the product could improve through updates without user effort.

Value-for-money was strong, with reviewers calling the value real and recommending the extra spend over cheaper models.
