Reporting a W5600H Corner-Cleaning Problem: What Support Needs to See
To report a W5600H corner-cleaning problem, send support the exact model, the date of use, the affected pane and corner, and a description of what you saw. Attach original photos taken from a safe indoor position and identify any visible pad or brush concern. Keep your observations separate from a suspected cause.
Describe the incident before naming a fault
Start with the result that prompted your message. "A small mark remained in the lower-left corner" gives support a location to review. "The sensor failed" assumes a diagnosis that a mark alone cannot establish. Use left and right as viewed from indoors, and state which side of the glass you cleaned.
Add what happened before you noticed the mark: the mode you selected, whether the pass completed or stopped, and any alert you observed. Quote the displayed text or describe the light and sound if you remember them. Write "not recorded" where you are unsure. Do not borrow an alert explanation from another model.
If you changed the pad or cleaned a component before taking the photos, include that in the sequence. Support needs to know whether a photo shows the setup during the incident or its condition afterward.
Keep the glass mark and the contact parts in the same report
The W5600H main pad wipes the broad glass area. At a framed corner, the bumper or sensing structure meets the boundary and occupies space the pad cannot cover. Bristles around that position help contact and clean the local glass patch beside the structure, supporting more complete corner cleaning. Frame shape, soil and setup still affect the result.
That division of work explains why a report should include both the glass mark and the adjacent pad and brush area. A photo of the robot's top alone leaves those contact parts out of view. The edge-brush mechanism guide explains their placement in more detail.

Use your own incident photos for the support report. The illustration explains the contact arrangement; it cannot establish the cause of a mark on your window.
Attach evidence without recreating the problem
Retrieve the robot according to its instructions before photographing its underside. With the unit off the glass and disconnected from power, photograph the visible pad boundary and brush area without dismantling parts. Photograph the affected glass from a safe indoor position. Do not lean outside or restart the robot just to obtain footage.
Keep an original photo alongside any annotated copy. On the copy, a simple arrow can identify the mark; avoid painting over the area support needs to inspect. Give each attachment a short name and use that name in your message, such as "Photo A: whole pane" and "Photo B: lower-left corner." State if you cannot obtain a requested view safely.
The glass-result inspection guide covers how to describe different areas of a pane. For the support handoff, keep the report focused on the incident and the evidence you already have.

Frequently asked questions
Do I need a video of the robot making the mark?
You can begin with a written account and photos taken after retrieval. If you already have a relevant video, identify the moment that shows the behaviour. Do not repeat an unsafe setup to make a recording. Follow the exact-model instructions and request guidance if you are unsure about continued use.
Should I identify the faulty sensor in my message?
Describe the visible location and attach a photo if you do not know the component name. A remaining corner mark does not identify a faulty sensor. Support can review the evidence without you assigning a cause or taking the unit apart.
What if I have no before-cleaning photo?
State that you have only an after-use photo. Include what you remember about the earlier condition, and label it as recollection. Keep the original image; avoid adding a reconstructed "before" view that could confuse the record.
