Well-reviewed budget window robot with four spray nozzles, six cleaning modes and a remote.
Verdict: Among the best-reviewed budget window robots. Its suction is lower than pricier models, so keep the safety tether on.
Budget window robot with ultrasonic spray and a 40 ml tank good for about 40 m² of glass.
Verdict: The cheapest credible way to try a window robot. Fine for occasional cleaning of a few large panes; step up to a station model if you have a lot of glass.
