Kyvol Cybovac S31 launches with self-emptying dock and laser mapping near $500
Kyvol released the Cybovac S31, pairing an LDS-based mapping system with a self-emptying dock and mop attachment at a price near $500, undercutting many self-emptying competitors of the period.
Full assessment
AutonomyL3 confirmed at launchReadinessFalls Short confirmed at launchScoreNot yet scoredReviewers confirmed the dock's dust capacity claims but found mopping limited to light surface passes. Long-term reliability of the dock and mapping accuracy across varied floor plans remains unverified beyond these early reviews.
Impact on autonomy
- LDS-based mapping enables room selection, no-go zones, and multi-floor map storage
- Four suction levels and app-based cleaning modes support targeted, zone-specific cleaning runs
Impact on readiness
- Self-emptying dock removes manual bin-emptying for up to 60 days between service
- Mop attachment adds wet cleaning but reviewers describe only light surface passes
Claim check4 claims reviewed
Self-emptying dock holds dust for up to 60 daysReviews of the 4.3-liter base cite the same 60-day estimate as the manufacturer's own figure without disputing it3,000 Pa suction across four adjustable power levelsReviewers list the same 3,000 Pa specification; independent suction measurement was not documented in available coverageUp to 240 minutes of runtime per chargeA third-party review measured roughly 65 to 80 minutes of typical per-cycle runtime, well under the spec sheet figure2-in-1 vacuum and mop cleans hard floorsReviews describe the mop pad providing light surface wiping without vibration or scrubbing, insufficient for ground-in dirtBottom lineThe dock and mapping claims held up in early reviews; the runtime figure and mop performance did not match the marketing language as closely.
Technical notes3 sections
- Launch Specifications
-
The Cybovac S31 reached retail through Amazon, Walmart, and AliExpress by January 2021, priced near $500. Reviewers compared it against self-emptying competitors then priced in the $550 to $599 range. The robot ships with a 14.4V 5,200mAh lithium battery and a 500ml onboard dust bin.
- Navigation and Mapping
-
The S31 integrates a laser distance sensor (LDS) to build a floor map, supporting virtual walls, no-go zones, and storage of maps for up to five floor levels. Cleaning modes include Auto, area, spot, and edge, across four selectable suction levels rated at 3,000 Pa.
- Dock and Mopping
-
The charging dock doubles as a self-emptying base with a 4.3-liter capacity, rated by the manufacturer to hold roughly 60 days of debris in a disposable bag. A snap-on 110ml water tank and removable mop pad add wet cleaning, described in reviews as a light wiping pass rather than an active scrubbing system.
