24. Lending a device to a guest: hygiene, card hold, breakage, liability
Oct 08, 2026"If I lend a sleep headband or a stimulator to a guest, who pays when they break it, and how do I clean it before the next one?"
The short answer
A lent device is managed like a rented bicycle: a card hold at handover, a condition check on return, a replacement price displayed in advance. Hygiene and liability fit on a one-page sheet per device, which the team applies without improvising.
The calculation or the proof
The price is already the market's. The Four Seasons in Los Angeles publishes a menu of wellness devices delivered to the room, from 50 to 75 dollars per day per device. This menu publishes no rule on hygiene, deposit or breakage. That is the gap we fill.
The IO8 calculation. A device from the IO8 stack is listed in the catalogue at 750 €. The guest pays 50 € a night, against a card hold. The device pays for itself in fifteen nights, in fewer than ten at the volume rate. Beyond that, it is margin, and the device stays at the hotel.
Hygiene has a recognised framework. The Spaulding classification, adopted by the US CDC, places objects in contact with intact skin among "non-critical" objects, for which low-level disinfection is sufficient. A headband, a ring or a stimulator placed on the skin fall into this category. Anything that touches a mucous membrane is excluded from lending.
What we cannot claim
We do not say that a lent device improves a guest's sleep or recovery. It is made available, with a sheet that states what it measures or what it does, without any claim.
We do not say that the card hold covers everything. It covers breakage and loss at the displayed price. The hotel's civil liability and the manufacturer's conditions are checked with its insurer, device by device.
We do not say that disinfection makes an object new. Wear parts (covers, tips, straps) are replaced; they are not cleaned indefinitely.
What a hotel can do now
Three cross-cutting rules, the same for every device.
Fixed equipment or lent device. What is installed in the room (lighting, micro-station, purifier, filtered carafe) is insured like the furniture. What is worn on the body is lent, against a card hold, with a condition check at departure.
Hygiene. A written procedure for each device: suitable product, contact time, visual check, storage in a closed cover, date of last cleaning visible to the next guest. Housekeeping is trained once, not at every stay.
Replacement price and consumables. The replacement price appears on the sheet and at booking, before handover. Consumables (covers, tips, masks) are included and renewed.
In the Mission, these rules become a procedure sheet for each device, handed to the team.
What the Living Lab measures
The devices in the IO8 stack are selected and tested at the Living Lab, near Lisbon, before being offered. The Living Lab is being equipped in waves; part of the equipment is being delivered.
Measurement planned: the time needed to restore each device between two users, device by device, published here with its date.
