# What is a photo-based cleaning audit?

A sign-off list says the task was done. Before/after photos leave how the area looked at that moment.

## What this page covers

- A checklist records completion; a photo archives appearance.
- The AI label is for workflow, not an audit certificate.
- No fixed accuracy percentage is marketed.

## What a checklist records

A classic form stores time, person, and a done box. Quality judgment stays human; the same area can score differently by inspector. A signature does not document appearance.

A signature stores time and person; it does not document appearance. The same area can score differently by inspector. A signature does not end manipulation risk.

- Form: was the task done?
- Photo: how did it look at that moment?

## What the photo adds

Before/after capture archives how the point looked. Hygio's model labels visible cues — stains, standing liquid, missing consumables, disorder — for workflow. Results vary with environment, angle, and light; we do not market a fixed accuracy percentage.

## What the score is not

Approved/Rejected (Clean/Dirty) is an internal quality signal — not a third-party audit certificate, sterility proof, or healthcare-hygiene compliance. Buyers see this limit in the FAQ and legal pages. The demo shows how the label is used on your point types.

## Buying note

The buying sentence is 'visual evidence layer' — not 'independent hygiene certificate'. That split belongs in the contract.

## Questions buyers ask

### Is a photo enough on its own?

Without location check-in it stays 'taken somewhere'. A signature stores time and person; it does not document appearance. Check-in plus before/after work together.

### Is the model always right?

No. It labels visible cues such as stain, standing liquid, missing consumables, and disorder; light, angle, and area type change results. That is why no fixed accuracy percentage is marketed. Evaluation happens in a pilot.

### Is the AI label an audit certificate?

No. Approved/Rejected is an internal quality signal for workflow. The buying sentence is 'visual evidence layer', not 'independent hygiene certificate'. That split belongs in the contract.

### Does a sign-off list end manipulation?

No. A signature's existence does not document appearance; the same area can score differently by inspector. A photo also does not make manipulation impossible — it stops a claim from being enough on its own.

### What do we see in the demo?

How the label is used on your point types, check-in and before/after flow, scores in the panel. 15–30 minutes, no credit card. No fixed-percentage promise.
