## Summary description

Ecovacs WG852-11EDR is a robotic window cleaner with suction-based operation powered by a 4500 mAh LiPo battery. Compact square body (271×271×77 mm) in white, suitable for universal glass and smooth surfaces. Battery operation allows cordless cleaning; practical for homes and offices where automatic window and glass maintenance is needed.

## Long description

The Ecovacs WG852-11EDR robotic window cleaner is a compact, battery-powered unit designed for suction-based cleaning of windows and other smooth, flat surfaces. With a square footprint of 271×271×77 mm and a 4500 mAh LiPo battery, the device operates without a tether, offering autonomous cleaning cycles for home and office glass. The white finish provides a neutral appearance suitable for most interiors, while a suction mechanism keeps the unit attached to vertical surfaces during operation.
Advantages
The cordless design with a 4500 mAh LiPo battery enables multiple cleaning runs without constant connection to a power outlet, simplifying placement on large or hard-to-reach windows. The suction-based system ensures steady adhesion to glass and flat surfaces, while the compact square form factor allows access to corners and narrow frames. The unit’s size and weight distribution are optimized for smooth sliding and stable motion across vertical planes.
Suitable for
Residential windows and glass doors
Office partition glass and interior glass walls
Shower enclosures and bathroom mirrors with smooth surfaces
Storefront windows and display glass (indoor use)
When it may not be suitable
The Ecovacs WG852-11EDR is designed for smooth, non-porous glass and similarly flat surfaces; it may not perform well on highly textured, frosted, or heavily soiled surfaces where suction or pad contact is compromised. Very large exterior windows exposed to weather, extreme temperatures, or outdoor conditions may require wired, professional-grade solutions with higher adhesion safety measures. Users should not expect the same performance on irregular, curved, or heavily framed surfaces.
Key specifications
Power source: built-in 4500 mAh LiPo battery for cordless operation
Dimensions: 271 × 271 × 77 mm (width × depth × height)
Operation method: suction-based adhesion with motorized cleaning pads
Suitable surfaces: smooth, flat glass and similar non-porous surfaces
Color: white
How to use
Before starting, ensure the glass surface is free of loose debris and large particles that could interfere with the cleaning pads. Charge the battery fully according to the manufacturer’s instructions, attach any required cleaning pads or cloths, and apply appropriate cleaning solution if recommended. Place the cleaner on the glass, engage the suction and start the cleaning cycle via the device controls. Monitor the first few runs to confirm proper adhesion and trajectory; remove and clean the pads after use and recharge the battery as needed.
What to consider before purchase
Verify that the primary surfaces are smooth, flat, and non-porous glass.
Consider window size and whether cordless run time meets the area to be cleaned.
Check access for placing and removing the device on high or exterior windows.
Ensure availability of replacement cleaning pads and compatible cleaning fluids.
Usage recommendations
For consistent results, lightly pre-clean heavy soiling and use manufacturer-recommended pads and cleaning agents. Regularly inspect and replace worn pads and keep the device charged to maintain reliable adhesion and cleaning performance on windows and smooth glass surfaces.
