Mamibot iGLASSBOT W168

The W168 is the square-body iGLASSBOT brought up to dual water spraying, which is the change that matters: the W120 generation needed the cloth pre-wetting by hand. The safety story is the other half of it, a 500 mAh UPS rated to 30 minutes of suction after a power cut, plus an alarm and a rope. What it still cannot do is move itself between panes, which is the ceiling on every window robot in this class.

Autonomy Ladder

Why Level II.

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.
IIIConditional AutonomyFinishes whole jobs in familiar spaces; struggles at the edges.
To reach Level IIIMost sessions finish without intervention. Rescue is occasional, not routine.
IIAssisted AutonomyThis robot

Mamibot iGLASSBOT W168 runs preset routines on its own, and the owner is its recovery system.

Navigation and control
Route-planned stripe patterns across three selectable modes, with edge detection and a return to the start point. No mapping and no pane recognition.
Why this level
- The machine plans a stripe route across one pane, detects edges, and returns to its start point without supervision.
- A person mounts it, manages the rope and power cable, and moves it to the next pane, so the unattended unit of work is a single mounted surface.

Robovations Score

Why the score is withheld

Not scored

The Robovations Score is withheld on this record. It is not a low score, and it is not an oversight.

Why

Our assessment did not establish an independent source for 7 of the nine inputs: task completion, coverage and navigation, edge-case recovery, operating envelope, field failure rate, software stability, support longevity.

The full assessment note

Those inputs carry 80% of the composite between them, so a number published here would be reporting the state of the record rather than the state of the machine. The unevidenced anchor is a reference point for one input, not a foundation for a whole score.

OWNERSHIP

Living with it.

A simple corded machine; cloth condition and ring seal decide whether any run finishes.

Mamibot's manual traces most stoppages to owner-correctable causes: air leaks from unseated rings or cloths, clogged spray nozzles, slippery worn cloths. Third-party owner reporting on the W168 is thin since its late-2024 release; the corded, rope-tethered design leaves little unattended failure surface.

Upkeep routine

Each useEvery cycle

Wash both microfiber cleaning cloths and let them dry fully; six cloths ship in the box, so a dry set is always ready. · Empty the 80 ml water tank, wipe the body down with a soft dry towel, and check the safety rope and extension cable for wear.

Seasonal4×/yr

Recharge the backup battery during storage; Mamibot specifies a full charge (about 2.5 hours) at least every 3 months to prevent deep-discharge.

As neededno fixed schedule

Swap in a dry cloth mid-job if the robot slips or streaks; replace worn-out cloths, which Mamibot classes as wear items with no published replacement interval. · Clear the two spray nozzles with the supplied cotton swabs when spraying stops on a full tank; a nozzle that will not clear needs replacing. · Re-seat the two cleaning rings and cloths if the suction alarm signals an air leak; the teeth on the body must sit in the ring slots. · Tighten the rotating-plate screws if movement turns rough or uneven.

Safety notes

CautionFall risk at height: Anchor the safety rope to an indoor fixture every run; cordon the area below exterior windows.

CautionUnsuitable glass types: Mamibot warns against cracked, uneven, or frameless glass; suction loss on these surfaces drops the robot.

NoteNo empty-tank alert: Nothing signals a dry 80 ml tank; watch the spray and refill mid-session.

NoteCorded operation only: Runs tethered to mains; the 500 mAh backup holds suction about 30 minutes after power loss.

Common questions

What people actually ask.

3 answered

OperationWhat is new in the W168 compared to the W120-T?

Dual self-spraying water, a brushless DC motor with an independent air duct, three route-planned modes, and a return to the start point after each run.

OperationWhat happens if the power fails while it is on the glass?

Mamibot rates the onboard UPS at up to 30 minutes of continued suction, with an alarm to prompt retrieval. The safety rope is the second line.

ComparisonCan it clean more than one window on its own?

No. It cleans the pane it is mounted on and returns to its start point. Moving it to the next pane is a manual step.
