Roborock S5

Name: Roborock S5
Brand: Roborock

LiDAR navigation that enabled room-specific cleaning at a consumer price point. The mop is convenience, not a core feature, drag-only, no water heating or pressure.

Autonomy Ladder

Why Level III.

One five-rung scale, every category, from acting only on command to working unsupervised anywhere.

VGeneralized AutonomyAny task, any setting. No consumer robot has reached it.
IVEnvironmental AutonomyHandles new obstacles and re-plans in real time; rare in consumer products.
To reach Level IVSustained operation across sessions, including layouts and conditions it has not met before.
IIIConditional AutonomyThis robot

Roborock S5 finishes whole jobs in a space it already knows, and still needs a person at the edges.

Navigation and control
LiDAR SLAM + app-based room mapping and no-go zones
Why this level
- LiDAR SLAM with room-aware mapping supports conditional autonomous operation.
- The S5 completes full-home cleaning cycles without human intervention, but navigation is confined to mapped, known environments.
- No obstacle learning or novel-situation adaptation.

How this number was reached

67of 100

Capable

DeficientLimitedCapableStrongExemplary

Capability40% of the score68What it does without you.

Task completion16% of the score68

Evidence

Trusted Reviews found floor debris "picked up almost perfectly, with only a trace amount of dirt left behind," with more left along the sides of the room. TechGearLab's tests were harder on it, recovering about 13% of pet hair from medium pile and 7% from low pile carpet and leaving roughly a 4 inch strip of debris along the edges, though it pauses, returns to recharge and resumes to finish the cycle.

Coverage and navigation10% of the score78

Evidence

GameSpace's owner account describes systematic coverage: it maps "back and forth lines in sections, just like how you would use a push vacuum" and rolls "a circuit along the outer floorboard" before moving to the next room, and by the second day "it had a good eye on the layout of the house and was running an efficient cleaning cycle." Modern Castle notes it can determine which areas are already done, charge mid-cycle and "return to the last spot it cleaned to finish."

Edge-case recovery10% of the score65

Evidence

GameSpace reports the S5 clears the 2 cm transition strips that stalled the owner's previous robot, and that between-room transitions "haven't been a problem even once." iFixit's S5 troubleshooting wiki documents the modes that still need a person: fibrous buildup jamming the wheels until it is pulled out by hand, and failure to find the dock when something blocks the signal path.

Operating envelope4% of the score50

Evidence

LiDAR makes mapping lighting-independent, which is a genuine widening. Against that the record names four documented degradations: suction loss on deep pile and shag, a gravity mop with no lift, no carpet detection on the mop side and no no-mop zones so carpet is protected only by removing the tank or closing a door, a 460 ml bin that needs weekly or twice-weekly emptying in shedding homes, and about 69 dB that puts early-morning runs outside common noise rules.

Dependability40% of the score74Whether it keeps doing it.

Field failure rate16% of the score94

Evidence

Nine years in market since September 2017 with a very large installed base, no recall and no systemic defect documented on the line, and the record credits it with establishing Roborock's reliability track record. Held in the mid sixties rather than higher because the failure evidence on file is owner-forum and retail review text (r/Roborock, Amazon) with the press review source still marked pending, and because a 2017 machine is now at or past battery service life with no vendor part behind it.

Software stability14% of the score77

Evidence

Roborock publishes firmware releases and a software and security support policy through its support portal, so the record is at least inspectable, and the file tracks fifteen-plus versions across 2018 to 2024 with no regression pattern raised in six years of owner-forum discussion. Held near the ordinary consumer case because nothing independent has ever analyzed whether those updates fixed more than they broke, and new firmware for this model has effectively stopped.

Support longevity10% of the score38

Evidence

Scored as commitments, and the commitments have largely lapsed. Discontinued in 2019, out of warranty for years, and the record states official Roborock parts are becoming harder to source and are now bought through resellers. What keeps this off the floor is that brushes, filters and pads are commodity parts abundant from third parties on Amazon and AliExpress, so the machine remains serviceable even though the vendor channel behind it has closed.

Ownership burden20% of the score52What it asks of you.

Routine maintenance12% of the score34

Evidence

Nothing is automated. Weekly bin emptying and mop pad hand-washing, monthly side brush and main brush axle cleaning and a cliff sensor wipe, and a water tank that must be emptied and dried whenever the mop is not in use because the feed is gravity driven with no valve to shut it off. Every mopping run begins with a manual fill and ends with a manual wash.

Consumables8% of the score80

Evidence

Main brush bristles at roughly 8 to 12 dollars a pair every three to six months, filter and pads at 15 to 20 dollars every six to twelve months, coming to roughly 35 to 45 dollars a year against a 549 dollar machine, about 7 percent of purchase price annually. Intervals and prices are both published in the record and third-party equivalents are abundant, so an owner can budget this precisely.

Reported, not scoredneither measures how well the robot works

Five-year cost$450

Lower third for robot vacuums as bought today. The 549 dollar MSRP is historical; the machine has been discontinued since 2019 and changes hands secondhand at roughly 250 dollars, plus about 40 dollars a year in brushes, filters and pads. No subscription of any kind, and no feature is gated behind one. A buyer should budget separately for a replacement battery, which is at end of service life on a 2017 unit and available only from third parties.

OWNERSHIP

Living with it.

Decade-old platform with firmware stabilization; navigation remains the strength, dock reliability and mop durability less proven.

Owner reports across 2018-2026 show LiDAR robustness and navigation consistency. Firmware updates addressed bump-sensor false-positives and cliff-detection drift. Mop attachment durability varies; pad clogging and water-pump wear noted after 18+ months in sandy/pet environments.

Common questions

What people actually ask.

5 answered

OperationDoes the Roborock S5 require a perimeter wire like older robot vacuums?

No. LiDAR navigation eliminates the need for boundary setup. The app defines no-go zones digitally. Setup takes 15-20 minutes for the initial map; user-drawn zones add another 10-15.

OperationCan the S5 clean multiple floors if I move it between rooms?

Yes, but mapping does not carry between floors. The S5 holds one active map and re-maps the level it is set down on, so moving it upstairs discards the map below it along with any zones or no-go lines drawn there. Storing separate maps per floor arrived on the S5 MAX and the S6; the original S5 was never given it.

OperationWhat happens if the mop pad dries out mid-run?

The robot continues vacuuming but mop performance drops without water. Manual refill is required; there’s no auto-refill dock or water-refresh mid-cycle. Owners schedule refills around room count and floor type.

OperationIs the S5 discontinued, and can I still get parts?

Yes, discontinued in 2019. Third-party brush and filter parts are abundant on Amazon and AliExpress due to the large user base. Official Roborock parts are becoming harder to source but still available through resellers.

OperationHow much noise does the S5 make, and can it run on schedules I won't hear?

Balanced mode measures about 69dB, ordinary vacuum-cleaner volume. Quiet mode is lower and draws less power at reduced suction, which lengthens the run rather than shortening it. Most residential noise rules cover night and early-morning hours, so a mid-day schedule while the home is empty avoids the restricted window; an early-morning start is the one that falls inside it.
