Deep cleaning and spectacular aroma
Size: 8 Fl Oz (Pack of 2), Size: 8 Fl Oz (Pack of 2)
This cleaner is super effective for removing difficult stains on any surface without leaving sticky residue. I love that the aroma is soft and fresh, in addition to being totally safe to use at home with children and pets.

Subtle smell, works well to pick up dirt!
Size: 8 Fl Oz (Pack of 2)
Has a nice, light smell when added to the Eufy C20 water. Smell is short-lasting and very subtle, so no irritation to the animals in the house. Easy to use, a small amount is recommended, and I find it works well. Very good value for long-lasting use. 1 cap/water refill, and the water is much nastier than it was when using just water. Very pleased with this purchase.

Easy cleaning and pleasant scent.
Size: 8 Fl Oz (Pack of 2)
It works very well with the robot vacuum cleaner. It cleans the floor without damaging it, leaves no residue or marks, and leaves a soft, pleasant scent. It lasts a long time and doesn't cause any problems for the device. A very good product; I would definitely buy it again.

So Worth the Purchase !!!
Size: 8 Fl Oz (Pack of 2)
I was a little hesitant to buy this since it’s a bit pricey for a floor-cleaning liquid. Still, I decided to give it a shot because the floor in my new apartment smelled stinky due to the pet urine from the previous tenant. It turned out to be totally worth the investment! The floor gets much cleaner with this product—the dirty water tank ends up way dirtier than usual—and the Eufy mop pads no longer smell bad like they used to without this liquid. Also, just a little goes a long way. I fill the tank to the max with water and add about 15ml of this liquid. The instructions say to dilute 10ml in 2 liters of water, and my tank holds about 2.5 liters. So with one bottle, I can refill the tank around 31 times—which is a lot! Since it needs to be heavily diluted, I don’t notice much of the scent after mopping. I do wish it had a stronger fragrance, but it gets the job done, so I’m very satisfied!

Works good but doesn’t make the house smell nice
Size: 8 Fl Oz (Pack of 2)
This works good in our robot vac/mop however it doesn’t make the house smell good when the house is mopped, just when you put it in the water tank. The floors are clean and that’s all I really care about but would it be nice to smell freshly mopped, yes.
