I would like to order one that can be used horizontally and vertically, will this work well?

Yes! This steamer supports Vertical & Horizontal steaming and Dry Ironing. You can iron large pieces of fabric and heavy denim easily, and get wrinkles out in minutes!

How does the indicator light change?

Plug in, the light changes from "flash yellow" to "flash red" after 15s Heat-up (Ready to use).

Short press to change the light from "solid red"(start steam).

Long press to change the light to "flash red" (Dry Ironing).

Does it work with 220v?

No, it's 120V. If you want to use it on 220V, you need to use a voltage converter + adapter plug by yourself.

Can it use standard tap water?

It is recommended to use de-mineralized or distilled water. If you use tap water, you may experience mineral build-up due to the high mineral content in the water supply in many cities, which may cause intermittent steaming.

Is this for travel, or can it only be used on a regular basis at home?

This device can be used both for travel and at home. But most people use it for everyday purposes because of its weight. For travel use, we would like to recommend another foldable steamer NB316A.
