This robot attaches to a window so it can handle all the dirty work. It has two power modes for different cleaning situations: battery and plugged-in, both of which are for different window setups.

It has a 6-in-1 multifunction station with an all-in-one attachment to handle the window cleaning jobs from start to finish. It also uses three nozzles for wide-angle cleaning alongside a wet cloth to better scrub down streaky, filthy windows. It handles all this with a brushless motor and intelligent path planning to give the most efficient clean possible. No more having to drag a paper towel or rag across the edges of windows for a streak-free shine.

If you want to give Mom a unique gift this year and help lighten her cleaning load, this window-cleaning bot is a surefire way to do it. Just grab it while it's discounted.
