I got this as a gift and it can't be returned sadly. I have a tile floor and even with it being vacuumed beforehand it gives a horrible result. Stripes and dirty splodges everywhere! Even while using the recommended cleaning product from Leifheit, something else non foaming or just water. The amount of water used also doesn't seem to make a difference. Was also tested with a different (wooden) floor with the same result. Doesn't do corners or edges, tank is too small, machine itself a bit heavy. Checked the manual and online to make sure I didn't do anything wrong. Overall just very disappointing, I was hoping for something much better seeing the brand has a good reputation. Just buy the leifheit normal mop and bucket things. It'll give a better result and you'll safe yourself tons of money.
