CNET review: MACH V1 Ultra Cordless Vacuum Hands-On,Built-In Steam Mop Impresses

You can use the V1 Ultra as a vacuum or put it into steam mop mode. MACH says its SteamWave technology works by "first dissolving the stain and then vacuuming and mopping the surface," with the steam continually released at a higher temperature of 230 degrees Fahrenheit (110C) "in order to remove dirt and bacteria."

V1 Ultra has a crisp LCD that displays the cleaning mode you're in and remaining battery life.

The MACH V1 Ultra uses something called Eco-Clean Ozone Disinfection to sanitize not just your floor but the vacuum itself, which has a self-cleaning mode. I could tell that the mop was working because a separate tank near the base fills with the moisture that has been vacuumed up as you mop the floor. After you're done mopping, you dump out the water from that tank and -- in my case -- it came out looking pretty dirty after absorbing some grime from my floors.
