Window robot fit checker
Compare your panes with a robot’s stated fitting requirements.

How this check works
Pane width ≥ maker minimum width; pane height ≥ maker minimum height; socket distance ≤ usable cable reach.
Assumptions & limits
Use the exact model’s manual. Dimensions are checked in the orientation entered. Flat, smooth, intact vertical glass only. A preliminary check cannot certify safe use.
Worked example
A 60 × 80 cm pane, maker minimum 400 × 400 mm, usable cable reach 4 m and a socket 3 m away, on smooth framed glass with a safe tether anchor.
Result: Entered dimensions pass this preliminary check. Always attach the safety tether and follow the maker’s instructions. This is not a safety approval.
Before you decide
- Find the exact model’s current instructions and confirm the UK version.
- Check fitting, consumables, paid features and the maker’s support statement.
- Keep uncertain details on your checklist and check the returns policy before buying.

The maker's indexed UK support table lists W2 OMNI, WG821-11, launch 2023-11-01 and end date 2026-11-01. That date is close: check for an extension before buying. The live page loads its model table dynamically, so confirm the entry directly with ECOVACS.
Manufacturer-stated specifications, not a performance assessment or safety approval. Cable lengths are separate and must not be added to infer safe working reach. Always attach the maker's safety tether; never lean out upstairs or use a ladder to place or retrieve a robot. Check returns and the current manual.
