Our verdict

The W100 is the promotional edition of Mamibot's round line, launched in 2024. It sprays from a pump through outlets that switch with the direction of travel, feeds them from a 50 ml tank, wipes with two rotating pads, and holds on with 2,500 Pa, the lowest grip in the catalogue. Its pressure sensors back it away from a frameless edge, yet Mamibot adds that frameless glass is not recommended for this model, and it is meant for panes tilted more than 25°. The safety case is better than the price class suggests: a 4 m nylon rope and a built-in UPS battery that keeps the suction going for 30 minutes with an alarm if the power fails. It is steered from the app or the remote, detects window locks, and names three cleaning routes without describing a planned pattern, so no route planning is credited here. No dimensions, weight, noise, speed, pane sizes or mode count are printed, the warranty is a year with six months on the battery, and there is no photograph, since Mamibot's site terms allow no reuse of its images.

Pros

  • Pumped spray that follows the direction of travel, from a 50 ml tank
  • 30 minutes of suction after a power cut, with an alarm, and a 4 m rope
  • Two rotating pads; app and remote control; window lock detection
  • Rated for glass and other smooth surfaces laid flat or upright

Cons

  • 2,500 Pa, the lowest grip in the catalogue
  • Frameless glass not recommended by Mamibot, despite the edge sensors
  • No route planning described, no dimensions, weight, noise or pane sizes
  • One-year warranty, six months on the battery; no photograph here

Best for

  • Framed interior windows and shower glass at the lowest outlay
  • A first try at a window robot where a fall would land on a lawn

Not recommended for

  • Frameless glass, which Mamibot itself advises against
  • Large or dirty exterior panes

In detail

Cleaning

It sprays water from a 50 ml tank.

Grip and fit

Suction of 2,500 Pa keeps it on the glass. It detects the pane edge, so frameless glass is fine. It also works on other smooth surfaces.

Safety

After a power cut it holds on for 30 minutes. A safety rope is included.

Navigation and control

It steers round obstacles. It comes with a remote.
