Inside the Winbot 730, a Robotic Window Cleaner

RECEIVER

Communicates with the remote control. The latest

production models communicate via radio frequency.

BUMPER SWITCH ASSEMBLY (2)

Signals the motherboard to back away when the

Winbot encounters an obstruction.

DRIVING TREAD UNIT (2)

Provides forward,

backward and turning

motion.

VACUUM SENSOR

CHAMBER

Monitors suction

levels on the

glass. Circuit

board instructs

the Winbot to

move around an

obstruction if a

loss of vacuum

is detected.

LITHIUM BATTERY

Can power the vacuum

pump for 60 minutes in the

event of power loss.

HANDLE

On/off

switch is on

back side.

CLEANING PAD AREA

(pad not shown)

AIR RELEASE BUTTON

Releases suction, allowing unit to

be removed from window.

CUPULE ASSEMBLY

Outer ring detects loss of suction.

Inner ring holds the Winbot to window.

The Winbot includes a safety pod to

prevent the device from falling if it loses

suction. The pod attaches to the inside of

the window and connects to the power

cord with a stretchable rope. Ecovacs

recommends it be used whenever cleaning

a window above the ground floor.

DRYING PAD AREA (pad not shown)

DROP-OFF SENSORS (4)

Two sensors in the front and two in the rear detect when

the Winbot has gone off the edge of frameless glass.

The Winbot requires human assistance for parts of the cleaning process.

The Winbot first measures

a window’s dimensions,

then it cleans from top to

bottom in a back-and-forth

pattern. It finishes by

cleaning the perimeter

before returning to its

starting position.

The Winbot holds no

cleaning fluid inside the

machine. Instead, a spray

bottle is used to apply

fluid to the front cleaning

pad before each use.

The Winbot cannot place

itself or move from

window to window by

itself. It must be

positioned and removed

by hand each time.

If a particularly stubborn

spot remains after the

cleaning cycle, a remote

control can be used to

have the Winbot reclean

the area.
