I bought a POLITI Vaporetto and I'm very happy. The device heats up very quickly and by turning the knob you can change the amount of steam generated. Another great feature. The water tank is separate, detachable and also translucent. This way you can see how much water is left while you work. If you need to refill, simply turn off the system, disconnect the tank and fill, reconnect and turn the system back on. Meanwhile, the water remaining in the boiler is still very hot, so you can get back to vaping in minutes. So far I've only used it on my tile floors, but it has many other uses as well.
