    What happened

    Reviewers 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.

    Bottom line

    The dock and mapping claims held up in early reviews; the runtime figure and mop performance did not match the marketing language as closely.

    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

    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 check

    4 maker claims checked against the record. Open one to read the finding.

    Self-emptying dock holds dust for up to 60 days
    Documented findingReviews of the 4.3-liter base cite the same 60-day estimate as the manufacturer's own figure without disputing it
    3,000 Pa suction across four adjustable power levels
    Documented findingReviewers list the same 3,000 Pa specification; independent suction measurement was not documented in available coverage
    Up to 240 minutes of runtime per charge
    Documented findingA third-party review measured roughly 65 to 80 minutes of typical per-cycle runtime, well under the spec sheet figure
    2-in-1 vacuum and mop cleans hard floors
    Documented findingReviews describe the mop pad providing light surface wiping without vibration or scrubbing, insufficient for ground-in dirt

    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.
