Our verdict

The W200 SkyBot is the only machine here that works with no cable at all. A detachable 3,350 mAh pack runs it for up to 100 minutes, about 30 m² of glass, and recharges in 100 minutes, so a spare pack keeps it going. It holds on with 2,000 to 2,600 Pa, raising the suction as it nears a frameless edge, which four sensors detect, plans its own route and returns to where it started. At 8 cm thick it is the slimmest robot Mamibot makes, it runs under 65 dB, and it is steered by a 2.4 GHz remote from up to 20 m. Safety is a 1.5 m rope to an indoor fixture plus a suction cup on a 2.5 m extension cable. The trade-offs are plain on the page: no spray, so you dampen the cloth yourself; no app, no voice prompts, no corner claim, no pane sizes, no weight, and a battery-powered robot has no mains to lose, so no power-cut figure applies. Mamibot's warranty is one year, six months on the battery. No photograph here, since Mamibot's site terms allow no reuse of its images.

Pros

  • Cordless: 3,350 mAh detachable pack for up to 100 minutes and about 30 m², recharged in 100 minutes
  • Suction rises from 2,000 to 2,600 Pa as it nears a frameless edge, detected by four sensors
  • Plans its route and returns to its start; 2.4 GHz remote with 20 m of reach
  • 8 cm thick, under 65 dB

Cons

  • No spray: the cloth is wetted by hand
  • No app, no voice prompts, no corner claim
  • 2,600 Pa peak, among the weakest grips here
  • One-year warranty, six months on the battery; no weight or pane sizes printed

Best for

  • Glass far from any socket, and anyone who dislikes cables on a window
  • Dry dusting of interior glass between proper cleans

Not recommended for

  • Dirty exterior windows, where a sprayed pane cleans better than a damp cloth
  • Anyone who wants to control the robot from a phone

In detail

Cleaning

It does not spray: the pad is wetted by hand.

Grip and fit

Suction of 2,600 Pa keeps it on the glass, with pressure compensation. It detects the pane edge, so frameless glass is fine.

Safety

The manufacturer states no power-cut backup. A safety rope is included.

Navigation and control

It plans its path and returns to where it started. It comes with a remote. It runs cordless.
