I had the opportunity to test the Dreame H14 Pro and was immediately impressed by how solid it feels. The first time I used it, I consulted the manual, which I highly recommend. After that, the device is practically self-explanatory. It's easy to operate, the display is clear, and you immediately feel like you're working with a powerful machine.
The results are good: my floor dries quickly and doesn't leave streaks. However, there are a few caveats. The H14Pro is heavy, so carrying it to another floor isn't fun. The drive system allows it to move forward on its own, which sounds nice, but in practice, it sometimes bumps into furniture or walls. Moreover, it doesn't fit under any cabinet or dresser, which is a shame because those are precisely where dust accumulates.
I also noticed that if there are loose hairs or lint, it blows them away. With pets in the house, this isn't ideal; it's better to vacuum first and then mop with the Dreame. And when you're done mopping, there's always a small puddle of water left behind, sometimes with a bit of dirt in it.
Cleaning the dirty water tank is definitely the least enjoyable part. You have to remove all the hairs and bits of dirt, and that's just plain dirty work. Fortunately, the mop dries well and stays fresh. The different settings are fun to try, but I don't notice much difference in results. The app doesn't really add much for me.
One thing is a shame: the base station leaves black marks on my floor. Luckily, you can wipe them away with the Dreame itself, but that takes a bit of time. All in all: a handy device that makes mopping a lot easier, but not perfect.
