Overview
The iGlassbot W120 is a budget square window robot from Mamibot, a Delaware-registered brand with its Asia-Pacific base in Shanghai. The original W120 appeared around 2018, followed by the W120-T, the W120-P with water spray and the W120-DP, which Mamibot calls its third spray generation and the thinnest window robot on the market as of 2024. Only the W120-DP was in stock in the US in October 2026. It lacks the battery stations and pad washing of the Ecovacs Winbot W2 and W3, but costs a fraction of the price.
