Overview
The S7 Pro is the current flagship of Taiwan's HOBOT, a company focused on window robots since 2010. Its square body and twin reciprocating mops reach 90-degree corners that round-pad robots miss, and 4,800 Pa suction lets it hold onto glass of any thickness. The main catch is the power cord, since it has no battery station and needs an extension lead for windows far from an outlet. Reviewers found it useful for large or hard-to-reach windows but slower than cleaning by hand. The older Hobot 2S remains on sale as the cheaper model.
