We have a Mint. His name is Frank. Right now, Frank, is scooting around dusting.
For reference: Our place is about 1500 sf, all hardwood except the bathrooms and kitchen, which have small, trim thresholds.
Frank uses cloths which came with him. Two dry and one wet. He also uses Swiffer cloths (or anything that fits on a Swiffer).
Advantages: He’s small, very quiet, and will zoom around and under anything to dust mop. He’s low-slung and square. There’s a cube thing that you set on a table or anything that is above the ground and that has a clear shot at the ceiling. That will become the center of Frank’s cleaning endeavors. If you want him in a different locale, you set up the cube somewhere else and start him up. The swiffer cloths are disposable and will pick up lots of dust and light debris. The cloths that came with him are washable microfiber. You could use any sort of microfiber towel or cloth if it was the right size. If you run him every day, the floors will be noticeably less dusty, and you’ll find that you are keeping things off the floor so as not to interfere. It runs for about 45 minutes, then will stop and wait to be told where else to go. Very easy to figure out/operate.
Cons: You have to plug it in to charge, unplug, and set him on his course. He doesn’t work on his own (unlike a Roomba). He doesn’t vacuum, so it’s basically pushing stuff around. If something doesn’t stick to the cloth, it just gets pushed into a corner (though this is usually big stuff like say packing peanuts or a piece of paper or the like that’s easy to spot and pick up). The dry cloths don’t seem to get super clean when washed, at least letting go of cat hair (we have two cats and they cause tumbleweeds). Because nothing is automated except the actual dusting, you have to remember to run it every day, or at least as often as you like. Basically, it wheels around, bangs into things, then backs up, changes angles, bangs into things, etc.
I want to use the wet cloth, but I tend to use the dry cloths much much much more.
It does not go over the thresholds to get into the bathrooms or kitchen. The type of cloths would snag on our kitchen tiles, which are the rough, slate-looking type.
On the whole, I find it useful because I don’t have to dust mop nearly as often and the cat hair remains under control.
Hope this is useful.
