I brought myself a 3 in 1. Google Maxkon 3 in 1 steam mop. I don't actually have the Maxkon brand, but they look very similar. I am having issues with mine over heating at the moment though and not sure why. I brought my friend the Maxkon brand and she hasn't had any drama.
We currently have a Bissell Steam Mop. I'm not a fan of them. I think a mop and bucket give a better finish and don't leave the surface with water stains. We also have a carpet/hard floor washer too, don't use it on the hard floors so much but cleans the carpets well.
We have a Wertheim vacuum and have never had a problem with it.
I have the H20 steam mop, I only have tiles (apart from bedrooms) and it only takes me 15min. We have open plan so the floors and with a toddler they can get pretty bad quickly, the mop has always given perfect results. No water staining or anything like that. Have buy shopping.
I have a Bissell and I love it We have a massive lounge/dining/kitchen plus hallway, wash house bathrooms etc, and it is so quick.
Wertheim used to be made by Singer, but I think now they are someone else... Electrolux maybe?
Supposed to be good and reliable according to a few friends, but I have never owned one myself.
