WINDOW ROBOTS COMPARED
Will a Window Robot Clean Every Window by Itself?
WINBOT W3 OMNI has a dock that washes its pad. Liectroux YW509 follows a cleaning route and sprays water, but its pad is washed by hand. Neither robot walks around the house looking for the next window.
Does a window robot find every window by itself?
No. You attach it to one pane, supervise it, remove it, and move it to the next pane. The robot automates the wiping path—not the entire trip around the house.
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.

ECOVACS WINBOT W3 OMNI
Window-cleaning robot with Vortex Wash stationIt sprays, wipes, follows a planned path, and returns near its starting point. You still attach it, supervise it, and move it to each new pane.
Homes with several large, flat panes, sliding glass doors, or sunroom glass that can be reached safely for attachment and removal.

- Pad care
- The Vortex Wash station washes the pad in about one minute, according to ECOVACS.
- Power
- Plug-in or built-in battery; ECOVACS claims up to 130 minutes per charge.

What changes or goes missing
- You have only a few small or irregular windows, or you cannot attach and retrieve the robot while staying safely indoors.
- A hands-on reviewer found that the pad could leave its own outline at the end, requiring one quick wipe with a cloth.
- The included cleaning solution can run out quickly. The manual directs owners to use ECOVACS WINBOT solution, so refills are an ongoing cost.

Liectroux YW509
Plug-in window-cleaning robot with dual water sprayIt sticks to the glass, sprays water, and follows a cleaning route. It is not cordless: keep it plugged in and attach the safety tether.
Several large, reachable glass panes when you are willing to wash and dry the pad yourself to spend less.
- What it does
- Dual water spray with N, Z, or combined route patterns on flat glass.
- Pad care
- Remove the pad, wash it by hand, dry it, and put it back. There is no self-washing dock.
- Power
- Runs from wall power. The backup battery is there to delay a fall during a power loss, not for cordless cleaning.
- Grip and water
- The maker lists 3,000 Pa suction and two 100 mL water tanks.
What changes or goes missing
- You cannot anchor the tether indoors, keep the robot powered, or supervise it throughout the job.
- The lower price removes the washing dock. Pad washing and drying come back to the owner.
- The cable, safety tether, and supervision are part of normal use, not emergency extras.
