The Vaporetto Smart Mop only uses water, steam, and pressure, which work together to dislodge grease and dirt from every corner of the home. This is a steam cleaner with a high pressure boiler that effectively cleans a wide range of surfaces quickly and naturally.
Per the manufacturer, the Vaporetto Smart Mop takes roughly 20 minutes to heat enough to let the steam build up. Then when you start mopping a tiny bit of water will come out followed by the steam. The safety cap will not unscrew if there is any pressure at all in the boiler, even when the appliance is turned off. I would suggest that you unplug the machine and wait at least 15 – 20 minutes until it completely cools down, and then the cap will come right off.
The Vaporetto Smart Mop is a steam cleaner only, not a vacuum. It does not suck up any dirt.
