So this product is good, working and take the harsh chemical away however has some drawbacks 1. Steam is low pressure which makes process very slow 2. The floor mat leaks Steam and straps are not strong enough 3. Using it is easy but emptying the water reservoir after use is painful process due to bad design and trying to avoid spills
All said the extra heads are good addition but add second extera mat or enable to change the length could make a higher pressure.
