I have been on the search for a good small compact steamer that wouldn't take much space up in the coach.
These two have good reviews and the prices aren't bad.
Enviromate P7 Pronto Portable 4-Bar Pressure Hand Held Steam Cleaner and Fabric Steamer
Or the Hoover TwinTank
Hoover TwinTank Disinfecting Handheld Steam Cleaner - WH20100
I like that they clean, sanitize, disinfect and steam not only clothing but they would be great for the drapes in the coach too. I say it's a must for those with asthma and allergies from dust, and even pet dander. We are considering one of these options maybe one of them will work for you?
