It makes the most sense when there is a lot of flat glass
People buy a window robot to reduce the repeated wiping on large glass, sliding doors, and sunroom panes. WINBOT W3 OMNI also washes its own pad in the dock, which matters most in a home with enough glass to make pad washing another chore.
Attach it to a pane and it sprays, follows a planned wiping path, and returns near where it started. That removes much of the arm work from each pane. W3 OMNI then adds the expensive convenience: its Vortex Wash dock cleans the pad instead of sending you back to the sink after a dirty pass.
The robot automates wiping, not the whole trip.
A person still attaches the robot, secures the tether, supervises it, removes it, and moves it to the next pane. Large flat glass makes that effort easier to justify.
Much of WINBOT W3 OMNI's price difference is the dock that washes the pad. A cheaper robot can wipe the glass while leaving pad washing to you.
