Question: Does it work on concrete floors
Document: I purchased this product with high hopes thinking that steaming my concrete stained floors would somehow provide better cleaning than just using a micro-mop like I have been using it. It does not. Although the product does work perfectly, I feel you are just at as well off by cleaning your floors with a micro-fiber mop.
I bought the Enviro steamer for our concrete floors since mopping can be too wet and I don't like the wasteful Swiffer pads. Turns out I'll be adding the Enviro steamer to the recycling pile sooner than I expected.The pads provided are ok but started falling apart after a few uses. I had better luck using my own homemade version. The steamer did work, just not as well as I had hoped.
Very good product. I have all stained concrete floors and the steamer is perfect for them. After mopping thoroughly, I use the Eureka. It's amazing how much additional "soil" comes up with the steamer.
I was looking for a product that I could clean my concrete floors with. Ended up having to mop the floors first, then steam cleaning. Without mopping first, it left smears.
I'm not one for writing many reviews here but i had to come back and say something about this. I don't need to sanitize my floors, i just wanted a way to clean my sealed concrete without chemicals.
Works as described. Is simple and easy to use and kind to my back. I use it on stained and sealed concrete floors and it does a good job and dries quickly. Like the way the pad clips on and stays put. Is effective in removing dirt from the surface.
Item was very easy to assemble. Using it was a breeze and the results beyond my expectations. I have tile and stained concrete floors throughout home. Flooring looks brand new. I will have to see what life span I get out of the reusable pads, but for now am very pleased.
This mop is so easy to use and really gets your floors clean. I use them on our concrete stairs to the basement where there is a lot of foot traffic and I swear the stairs repel dirt after using this mop so I can go longer before cleanings. If that doesn't make it worth it - I'm not sure what would.
I love this thing. I thought I would try it since it was inexpensive. I have acid etched concrete floors with a mediocre sealant on them. I thought they would be too rough for the cleaner but it works great. It is about 20 minutes of steam. Stickiness and general dirt gone. No smell or residue. It's cheap and works great.
I live in an apartment with all concrete floors, which can get very messy and dirty pretty easily. I've gone through several mops and all the hassle, wasted time and money on Swiffer wetjets, and finally found this little beauty. It's a perfect replacement for all those, at a low cost, and without needing lots of chemicals.Pros:- Fast heatup time!
Answer: It works on concrete floor that was stained/painted.  Have not tried it on totally porous concrete.
