The Steva can kill germs, viruses, dust mites... even bedbugs... with nothing more than water. Almost instantly, this steamer heats water to over 240 degrees and the steam it creates is pressurized. Not only can this hot steam help to remove the most caked-on dirt, the high heat helps you to remove it with greater ease. You can do everything from steam cleaning your toilet to curtains and windows, bedding and mattresses... people even use the power of steam to unclog drains! The only surfaces these won't clean are unsealed or delicate materials, electronics and the like.
