Description
Compact Window Cleaning. Precise Edge Coverage. Smart Automated Control.
The Ecovacs WINBOT Mini 2 WG853 is a compact robotic window cleaner designed to make glass cleaning easier, smarter and more consistent. Measuring just 215 × 215 × 55mm, it is Ecovacs' slimmest and lightest WINBOT design, allowing it to work effectively on smaller panes, narrow windows and tighter spaces where larger window-cleaning robots may struggle.
Powerful suction of up to 8,000Pa keeps the robot securely attached to compatible flat glass surfaces, while WIN-SLAM 4.0 intelligently maps and plans an efficient cleaning route. Four upgraded corner brushes, an enlarged microfibre wiping pad and ultrasonic atomisation spray work together to clean right up to approximately 1mm from window edges.
Multiple cleaning modes let you choose between fast everyday cleaning, deeper stain removal, targeted spot cleaning and dedicated edge cleaning. The ECOVACS HOME app also allows close-range Bluetooth control, including four-direction manual movement for more precise positioning when required.

Frequently Asked Questions
Is the Ecovacs WINBOT Mini 2 a robot vacuum?
No. Despite sometimes being grouped with robotic cleaning products, the WINBOT Mini 2 is specifically a robotic window cleaner designed for compatible flat glass surfaces.
How small is the WINBOT Mini 2?
It measures approximately 215 × 215 × 55mm, making it particularly suitable for smaller panes and narrow window areas.
How much suction does it have?
The WINBOT Mini 2 delivers maximum suction of up to 8,000Pa, with approximately 3,400Pa stated while moving.
How does it stay attached to the window?
A powerful blower motor creates suction between the robot and the glass. The wiping pad design and real-time air-pressure monitoring also help maintain a stable seal.
Can it clean frameless windows?
Yes. The WINBOT Mini 2 is designed for both framed and frameless compatible flat windows.
Can it clean floor-to-ceiling windows?
Yes, provided the glass meets the required size, thickness and flat-surface specifications and the safety rope can be secured correctly.
What is the minimum window size?
The stated minimum glass area is approximately 25 × 25cm.
What is the minimum glass thickness?
The glass should be at least approximately 3mm thick.
Does it clean right up to the frame?
The upgraded corner brushes are designed to clean to within approximately 1mm of compatible frames and edges.
How do the corner brushes work?
Friction against the window frame helps rotate the brushes at up to approximately 84rpm, allowing the fine felt bristles to clean close to the edge.
Does it spray water automatically?
Yes. The WINBOT Mini 2 has automatic ultrasonic water spraying, and spray can also be triggered manually from the ECOVACS HOME app.
How large is the water tank?
The integrated tank holds approximately 50ml of water.
What is ultrasonic atomisation?
High-frequency vibration converts the water into an extremely fine mist, with droplets stated to be as small as approximately 10 micrometres. This helps wet and loosen dirt without producing large water droplets.
How many spray nozzles are there?
The WINBOT Mini 2 uses four spray nozzles.
Does it tell me when the water tank is empty?
Yes. A water-tank-empty reminder is supported.
What type of cleaning pad does it use?
It uses a dual-sided microfibre wiping pad measuring approximately 215 × 214mm.
How much pressure does the pad apply?
The supplied specification states approximately 14N of downward wiping force.
What cleaning modes are available?
Available modes include Fast Cleaning, Deep Cleaning, Thorough Cleaning, Edge Cleaning, Spot Cleaning and Remote Control mode.
What is WIN-SLAM 4.0?
WIN-SLAM 4.0 is Ecovacs' navigation algorithm for WINBOT. It identifies window dimensions and edges, plans a systematic route and helps the robot respond intelligently to narrow areas and obstacles.
How fast does it clean?
In Fast Mode, a 1m × 1m section of glass takes approximately 2 minutes 30 seconds under the stated test conditions.
Can I control it manually?
Yes. The ECOVACS HOME app provides four-direction manual control over a close-range Bluetooth connection.
Does it return to where it started?
Yes. The WINBOT Mini 2 supports automatic return to its initial position after the cleaning cycle.
Can it avoid obstacles?
Yes. WIN-SLAM 4.0 combines obstacle detection, frame recognition and anti-stuck logic to help it navigate around raised areas and confined spaces.
What happens if the mains power fails?
The built-in 3000mAh emergency battery is designed to keep the robot attached to the glass for more than approximately 30 minutes, giving you time to retrieve it safely.
Does the battery power normal cleaning?
No. Normal operation is mains powered. The internal battery is primarily used for safety protection in the event of power loss.
Does it come with a safety rope?
Yes. A 3.3m backup safety rope and carabiner are included and should be secured correctly before each cleaning session.
How strong is the safety rope?
Ecovacs states that the supplied rope can withstand pulling forces of up to approximately 1,600N.
Can it be used on very dirty windows?
Yes. Deep and Thorough cleaning modes are designed for heavier dirt, although heavily contaminated glass may benefit from removing large loose debris manually before using the robot.
Can it clean outside windows?
It can be used on compatible accessible exterior glass where the robot can be safely attached and the safety rope securely anchored. Always follow Ecovacs' safety instructions, particularly when working above ground level.
Can it clean curved glass?
No. The supplied specification identifies compatible surfaces as flat windows.
Can I use ordinary household glass cleaner in it?
Use only cleaning liquids approved by Ecovacs for the WINBOT system. Unapproved detergents may foam, leave residue or affect the spray system.
Does it include cleaning solution?
Yes. A 230ml bottle of cleaning solution is included.
How many cleaning pads are included?
Two wiping pads are supplied in the box.
How should the wiping pads be maintained?
Remove and clean them regularly according to Ecovacs' instructions, then allow them to dry properly before reuse. Heavily dirty pads can reduce cleaning performance.
Is the WINBOT Mini 2 easy to store?
Yes. Its slim 215mm square body and lightweight construction make it easy to store in a cupboard or other compact space when not in use.
The Ecovacs WINBOT Mini 2 WG853 combines an ultra-compact design, 8,000Pa maximum suction, ultrasonic spray, precise edge cleaning and intelligent WIN-SLAM 4.0 navigation to make routine window cleaning considerably easier — especially on narrow panes and difficult-to-reach glass areas.
