iGLASSBOT W168
Limited evidenceRead the findings →Mamibot's mid-range round window robot, with two spinning pads and a twin sprayer. Mamibot pitches it at upright windows, framed or frameless. Its round pads can't reach into square corners, so expect to finish those by hand.

What we know
The details here come from Mamibot's product page and its Mamibot overview, which suggests the W168 or W100 for compact round cleaning. The closest real-world evidence comes from owners of the cheaper W100 on DNS buyers, who report dirty corners and second passes. The W168 uses the same round two-pad layout, adding a bigger tank, a longer rope and a stronger promise on frameless glass.
What Mamibot promises
Mamibot lists two spinning pads, twin mist sprayers, an 80ml clear tank so you can see the water level, three cleaning routes and a return to where it started after each clean. Mamibot suggests a dry run first on very dirty glass, then a wet one. Suction is quoted at 2 to 3kPa, from a brushless motor Mamibot says is quieter.
Round pads can't reach corners
Like the W100 and HOBOT's round models, the W168 moves on two circular pads, and circles can't reach into a square corner. Owners of the cheaper W100 on DNS buyers say they wipe the corners by hand afterwards. Mamibot says its spray covers every corner, but that's about wetting the glass, not wiping it. Expect to finish the corners yourself.
Frameless edges
Mamibot says pressure sensors make the W168 back off when it feels the edge of frameless glass, and cliff sensors help on a pane with one unframed side. That's a stronger promise than for the W100, which Mamibot doesn't recommend for frameless glass. It still wants surfaces tilted more than 25 degrees and rules out cleaning the underside of flat glass.
Safety depends on the rope
The W168 plugs into the mains. Mamibot says its backup battery keeps the suction on for up to 30 minutes with an alarm if the power drops, and it comes with a 5m safety rope. Both are the maker's claims. On an outside window, tie the rope to something solid indoors before you start, as you would with any mains window robot.
What's not checked yet
Nobody has tested the W168 itself, so the main questions are open. How clean it leaves the glass, and whether it needs the second passes W100 owners on DNS buyers describe. How loud it is, given Mamibot says its brushless motor is quieter. Whether the pressure sensors really make it back off frameless edges. And how long the backup battery holds on if the power cuts out.
Our take
Should you buy the iGLASSBOT W168?
Best for: Large windows cleaned regularly, with a socket nearby. Skip it if: You want a stronger record in independent tests before buying.
Hold off until someone tests it. On paper it's a sensible round-pad robot for upright windows, framed or frameless, with a bigger tank and a longer rope than the W100. For now, the Ecovacs WINBOT mini has two home tests behind it, and the HOBOT 388 is a tested round-pad robot that mists the glass in a similar way.
The W168 sits above the W100 in Mamibot's round-robot line. Mamibot calls it a 2024 upgrade: two spinning cloth pads, water misted in two directions from an 80ml clear tank, three cleaning routes and an automatic return to where it started. You control it from an app, a remote or the button on top. It runs from the mains, with a backup battery that Mamibot says holds it on the glass for up to 30 minutes if the power fails, and a 5m safety rope.
The catch is the corners. Round pads can't reach into square corners, and owners of the cheaper W100 say they wipe corners by hand. Mamibot's product page also offers the W168 to other brands to sell under their own names, so check the model details closely if you see a similar round robot with a different badge.
Before you buy
The questions people ask about this one
Will it work on frameless glass?
Mamibot says so. the specifications describes pressure sensors that pull it back from a frameless edge, and cliff sensors for panes with an open side. Nobody has tested that independently, so watch the first run on frameless glass closely.
What happens if the power cuts out?
the specifications says a backup battery holds suction for up to 30 minutes, with an alarm, and a 5m safety rope comes in the box. It won't keep cleaning on battery, and nobody has tested the backup independently.
Does it leave streaks or edges?
Not tested on the W168. Owners of the round W100 on DNS buyers say corners stay dirty and dirty glass often needs a second pass. The W168's round pads leave the same gap in the corners, so keep a cloth handy for them.
Do I need a special cleaning fluid?
the specifications doesn't ask for a special fluid; it talks about a water mist and suggests a dry pass first on heavy dirt, then a wet one. The 80ml tank is clear, so you can see when it needs topping up.
Can it clean mirrors and tiles?
Besides windows, the specifications lists mirrors, smooth walls, floors, ceramics and laminates. The surface should be tilted more than 25 degrees, and Mamibot warns against cleaning the underside of horizontal glass.
Alternatives
Other window-cleaning robots to compare.
WINBOT MINI
Why consider it: Two German home tests found it left small and medium panes mostly streak-free after one pass.
The compromise: It needs a socket nearby too, and one tester saw dirt left in the last millimetres at the frame.
388
Why consider it: Another round-pad robot that mists the glass, and two tests got clear glass from a dry pass then a wet one.
The compromise: It's slow and loud, it leaves the corners, and both tests date from 2021.
S7 Pro
Why consider it: HOBOT's two-pad model, and TechRadar found it spot on at detecting frameless edges.
The compromise: Both tests found streaks on dirtier glass, and it saves effort rather than time.
