Polti Vaporetto SV450 Double test: the steam cleaner that does double duty

While the steam cleaners in our comparison take an average of 30 s to preheat the water and be ready for use, the Polti Vaporetto SV450 Double only takes 18 s. To test its washing efficiency, we use it on 4 types of stains previously made on the floor of our lab: oil, sugary drink, lipstick, carbon mixed with water (to simulate soot, a black and greasy stain that sticks). a passage to the Vaporetto SV450 Double to remove traces of sugary drink and fat. The carbon black is completely erased after ten passages, even if it rather spread during the first 5. Finally, we are pleasantly surprised to note that this model has overcome the red stain at lips, which very often is the only one to resist. Indeed, 14 passages are enough to completely remove the trace on the ground. In comparison, after 20 passes, the Shark S6003EU still failed to completely erase the lipstick stain.
