Our protocol consists of trying to remove four types of stains: oil, sugary drink, lipstick, carbon mixed with water (to simulate soot, a black and greasy stain that sticks). And the results obtained with the H11 Max turned out to be a little more disappointing than those of an FC 5 from Kärcher.
In particular, it took him 3 round trips to completely erase the traces of dried soda and well encrusted on the ground, while it only took one for the Kärcher. The oil stain turned out to be less stubborn, since it completely disappeared after 2 “only” trips.
As was the case with the Polti Vaporetto 3 Clean, the carbon mixed with water leaves a not very discreet trail, but which fades after 6 round trips. As for the lipstick marks, they are still a little visible after more than 20 round trips of the rollers and we had to rub the floor energetically by hand to erase them completely.
The washing performance is therefore decent, but it remains a notch below that of motorized floor cleaners from Kärcher. On the other hand, we found absolutely no complaints about the performance of the H11 Max when it absorbs liquids, sauces or eggs. He managed to clear the floors without any difficulty, provided however that the stains had not had time to dry – and therefore to become embedded – on the floor.
