I have the yellow Lidl one. Use it clean sink, toilet bowl, mirror, bathroom dirty spots, kill some weeds next to wall....clean car parts. It does not work on big things, but some oily/grime/sandy/salty suspension parts...first detergent, then steam, then oil, then steam, then impact wrench....that sort of stuff.
Also works fine, when a little part is soaked days in vinegar and then steamed...clean and when hot dries fast. Needs welding fast or slight spray of oil.
