Kyvol Cybovac S31 Smart Laser Robot Vacuum

Name: Kyvol Cybovac S31 Smart Laser Robot Vacuum
Brand: Kyvol

The S31 was designed to map rooms with LDS laser navigation and empty its own dustbin at a self-emptying base, but it is not currently purchasable through Kyvol's official US store, and signs of catalog neglect raise real doubts about ongoing parts and software support.

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

Kyvol Cybovac S31 Smart Laser Robot Vacuum finishes whole jobs in a space it already knows, and still needs a person at the edges.
What it does on its own
- Builds a room map using LDS laser navigation and plans its own cleaning route; empties its own dustbin into a self-emptying base station without prompting; controllable through the Kyvol app or Alexa and Google Assistant voice commands; vacuums and mops in a single pass using an external water tank.
Why this level
- The robot builds a room map with LDS laser navigation, plans its own cleaning route, and empties its own dustbin into a self-emptying base without prompting.
- A person must still fill and attach the external mop water tank, set no-go zones in the app, and periodically empty the base's dust bag, consistent with Level III, Conditional Autonomy.
What holds it at Level III
- Every model on Kyvol's official US store, including the S31, was listed as sold out at the time of this research. Two other catalog SKUs (Cybovac S32, Cybovac S60) returned 404 Not Found and were priced $0.00 in the site's own product listing, and a separate model showed an inconsistent $5,999.99 price on one page while its own product page marked it sold out, consistent with an unmaintained catalog. No independent review, owner forum, or trade repair source for the S31 was found. Third-party listings located (Newegg) show only refurbished units and replacement parts, not new complete units.

Human Readiness

Falls Short.

As of this research the S31 is not purchasable anywhere on Kyvol's official US store, where it and every other listed model show as sold out. The wider catalog contains broken product pages and inconsistent pricing consistent with reduced vendor upkeep, and no new-unit retail channel could be confirmed, so current buyer readiness is low regardless of the robot's original design.

Where this sits on the readiness scale

Capability40% of the score55What it does without you.

Task completion16% of the score82

Evidence

Modern Castle ran a full cycle and reports 'It was able to navigate the entire space, did not get stuck, and returned to the docking station', docking on the first run, and Computer Weekly watched it return to base at the end of a program and empty itself into a base that holds dust for up to 60 days, so nobody services it between runs. The deduction is iMore, whose unit got stuck once mid-run between a desk chair and a desk leg and whose only app notification was the unhelpful 'Start it at another location', so a human still closes the loop occasionally.

Coverage and navigation10% of the score55

Evidence

The manufacturer states a laser navigation system (LDS) with real-time home mapping and route planning. No floor-map storage count, missed-region behavior, or independent coverage testing was found in any source reviewed, so this rests on the manufacturer's description alone.

Edge-case recovery10% of the score25

Evidence

Scored at the unevidenced state (25) under section 2 rule 2, which is a value rather than a ceiling: it is what the record scores until evidence moves it upward, and it is not a finding against the machine. No source reviewed described how the S31 behaves when stuck, tangled, or lost mid-run.

Operating envelope4% of the score25

Evidence

Scored at the unevidenced state (25) under section 2 rule 2, which is a value rather than a ceiling: it is what the record scores until evidence moves it upward, and it is not a finding against the machine. No source reviewed described the S31's behavior across floor types, thresholds, or clutter no carpet-detection or threshold-crossing specification was found for this model.

Dependability40% of the score41Whether it keeps doing it.

Field failure rate16% of the score40

Evidence

No owner forum, trade repair source, or independent review of the S31 was found. Third-party listings located (Newegg, per this research) show refurbished units and replacement parts rather than confirmed new stock, consistent with an aging installed base but not itself a failure record in either direction. No public owner channel for this platform was identified; and with the product off sale for well over 24 months, this input is scored well below a neutral midpoint rather than credited for an absence of documented failures.

Software stability14% of the score53

Evidence

No version history, release notes, or update cadence for the S31 was found in any source. Kyvol's own catalog shows signs of reduced upkeep: two other SKUs (Cybovac S32, Cybovac S60) return 404 errors and are priced $0.00 in the site's own listing, one model shows a $5,999.99 price inconsistent with that same model's own sold-out product page, and every model including the S31 is marked sold out. This is circumstantial evidence of vendor site neglect, not a confirmed statement that the software or app channel has been withdrawn, and is scored accordingly: below the neutral no-channel ceiling, but above a confirmed-shutdown level.

Support longevity10% of the score25

Evidence

As of this research, every model on Kyvol's official US store, including the S31, is listed sold out. Two other catalog SKUs return 404 Not Found and are priced $0.00, consistent with orphaned or abandoned listings rather than currently shipping models. No stated multi-year support commitment or confirmed active parts channel was found; the only located aftermarket sources (Newegg) show refurbished units and replacement parts rather than vendor-supplied new stock. This matches an orphaned-line pattern.

Ownership burden20% of the score51What it asks of you.

Routine maintenance12% of the score55

Evidence

The base station empties the onboard dustbin automatically, rated for up to 60 days between manual bag changes (manufacturer). Mopping draws from a manually filled and emptied external water tank with no self-washing pad system, so that portion of upkeep remains fully manual on every run.

Consumables8% of the score45

Evidence

The self-emptying base station requires periodic replacement dust bags, and no generic-compatibility or pricing information was found for this platform. The mop uses a manually filled external water tank rather than disposable pads, so no recurring pad purchase is indicated. Given the apparent reduced vendor upkeep evident elsewhere in the catalog, ongoing sourcing of proprietary dust bags carries real uncertainty.

Reported, not scoredneither measures how well the robot works

Five-year costNot costed

Historical MSRP was $519.00. The product is not currently purchasable through Kyvol's official US store, so a current price cannot be established, and with the product not purchasable at any price, no five-year total is computed. Consumable costs (replacement dust bags) were not priced in any source reviewed.

Data postureCloud-linked

Account required. Maps and telemetry leave the home; core function survives an outage.

What leaves the homeDocumented

Controlled through the Kyvol app or Alexa and Google Assistant voice commands, which implies an account and network connection for scheduling and remote control. No source reviewed disclosed where room-map or usage data is processed or stored, or whether core start/clean functions remain available from the robot itself without an active app connection.

Common questions

What people actually ask.

5 answered

OperationIs the Cybovac S31 currently available to buy new?

Not as of this research. Every model on Kyvol’s official US store, including the S31, was listed as sold out.

OperationDoes it empty its own dustbin?

Yes. The manufacturer states the base station empties the dustbin automatically and is rated for up to 60 days of dust capacity.

OperationDoes it wash its own mop?

No. It mops using a manually filled external water tank rather than a self-washing pad system.

OperationIs Kyvol still supporting this product?

This could not be confirmed. Every model on the company’s official US store was sold out at the time of this research, and two other catalog listings returned 404 errors, which raises questions about the catalog’s current maintenance, though no announcement of a company closure or discontinuation was found.

OwnershipWhere can a replacement unit or parts be found?

Third-party listings located during this research (Newegg) show refurbished units and replacement parts rather than confirmed new stock.
