Ecovacs Winbot Mini 2

Name: Ecovacs Winbot Mini 2
Brand: Ecovacs

Small enough to fit a 25 cm pane, and a single owner's 90-day log reports edges almost as clean as the middle and no falls in more than 60 cycles. Large windows take it a long time.

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

Ecovacs Winbot Mini 2 finishes whole jobs in a space it already knows, and still needs a person at the edges.

Navigation and control

WIN-SLAM 4.0 path planning with frame and obstacle detection
Why this level
- WIN-SLAM 4.0 path planning, frame detection down to 1 mm and edge modes let it clean a pane and return to its start point without steering, per Ecovacs.
- An owner's 90-day review reports it freeing itself from corners.
- That is Level III: Conditional Autonomy for a window robot.
Autonomy dimension 66 / 100 · 3 sources reviewed
IIAssisted AutonomyRuns preset routines; stalls at anything new.
IManual AutomationOne action on command; no independent operation.

Capability40% of the score71What it does without you.

Task completion16% of the score72

Evidence

Window cleaners: a 90-day owner review on Window Robot Lab found small windows left very clean with edges near the middle's quality, while large windows took impractically long and the 50 ml tank needed frequent refills.

Coverage and navigation10% of the score75

Evidence

Window cleaners: Ecovacs lists WIN-SLAM 4.0 path planning with 1 mm frame detection, and the owner review estimates about 99 percent edge coverage in Edge Mode.

Edge-case recovery10% of the score70

Evidence

Window cleaners: the owner review reports the robot freed itself when stuck in corners and recorded no falls or near-falls across more than 60 cycles; this rests on a single anonymous owner.

Operating envelope4% of the score58

Evidence

Window cleaners: Ecovacs limits it to flat glass at least 3 mm thick and panes from 25 cm square; the owner review found it impractical on large windows and constrained by cable reach.

Dependability40% of the score60Whether it keeps doing it.

Field failure rate16% of the score65

Evidence

Under twelve months of field record, from one owner's 90-day log: a leaking spray bottle after a month and cable tangling, but no job-stopping hardware failure. A single anonymous owner is thin evidence.

Software stability14% of the score55

Evidence

The owner review reports the app connection dropping roughly every 15 to 20 cycles, with no documented fix.

Support longevity10% of the score60

Evidence

Scored as commitments: Ecovacs advertises accidental damage insurance for falls caused by loss of suction and sells the model and accessories through its US store. No multi-year update commitment is published.

Ownership burden20% of the score72What it asks of you.

Routine maintenance12% of the score66

Evidence

The owner places and removes the robot on each pane, refills the 50 ml tank every three to four small windows and manages the power cable, per the owner review and Ecovacs' specifications.

Consumables8% of the score80

Evidence

Parts are washable double-sided microfiber pads and cleaning solution (230 ml supplied), per Ecovacs (priced by the consumables engine).

US list price $239.99 with no subscription; Ecovacs publishes no pad or solution replacement intervals, so a five-year figure is not stated.

Common questions

What people actually ask.

5 answered

OperationHow small a window can the Winbot Mini 2 clean?

Ecovacs lists a minimum pane of 25 x 25 cm and glass at least 3 mm thick.

OperationWhat happens if the Winbot Mini 2 loses power on the glass?

Ecovacs says a backup battery keeps it attached for 30 minutes, and a 3.3 m safety rope is included.

OperationDoes the Winbot Mini 2 run on a battery?

No. It runs on a 4.7 m mains cable; the 3,000 mAh battery is only for power-loss protection.

OperationHow many windows can it clean on one tank?

The tank holds 50 ml. One owner found that covers three to four small windows in Deep mode.

OperationHow does the Winbot Mini 2 differ from the original Winbot Mini?

Ecovacs lists WIN-SLAM 4.0 navigation, upgraded corner brushes and a thinner 55 mm body for the Mini 2. A full side-by-side comparison has not been published.
