Window robots you can buy now

I track 8 window robots sold on their makers’ own US stores. All 8 are in stock, from $178.60. Every one is an Ecovacs WINBOT, and 4 can run on battery. They clean flat glass only.

I looked at 23 window robots; 8 are listed. See the 15 I left out, each with its reason.

Smallest pane and battery time are the maker’s own figures. On Oct 30 the store showed three of these prices as sales with a countdown (mini 2, W2S OMNI, W3 OMNI), so they may change soon. “Plug-in only” means the maker states no battery runtime; the robot still holds on for over 30 minutes if the power cuts out.

Before you buy

Three things the maker’s own pages say, which are easy to miss.

Flat, clean glass only

ECOVACS says the glass must be smooth and “free of decals or stickers, cracks, obstacles under 4 mm, or frames under 2 mm”, and the window should not be “too small, curved, or irregularly shaped”.

It also says to keep the glass “free of condensation or oil stains” and: “Do not use the robot in extremely cold or hot conditions.”

Measure your smallest pane

The smallest window ECOVACS lists is 22 x 25 cm for the mini, 25 x 25 cm for the mini 2, and 30 x 40 cm for the W2S models and the W2 PRO OMNI. The W3 OMNI page doesn’t say.

Every spec table that lists it asks for glass at least 3 mm thick.

Battery or a cord

The four OMNI models can run on battery, for up to 110 or 130 minutes, or plugged in. The other four must stay plugged in.

All eight hold on for over 30 minutes if the power cuts out, and come with a safety rope. ECOVACS sells a 1- or 2-year extended warranty on top of the standard year.

Straight answers

Counted from the robots on this page, in their makers’ own words. A maker that doesn’t say is counted as not stated. How I count and date answers

Do window robots work on framed windows?

Most do, on flat glass. Each robot’s page lists the glass its maker rules out.

Checked Oct 30, 2026, the oldest check among the 8 robots counted.

Do window robots run on battery?

Half of them do. Plug-in models need an outlet near the window.

How small a window can a window robot clean?

It depends on the model.

What else can a robot do?

Cleaning windows is one of the five chores robots already do. See which chores are next, and the humanoids aiming at the rest.
