My first experience with a Robot vacuum
Color: White
I am liking this robot vacuum. It is very easy to program and can be done from your phone. It has mapping capabilities which helps with learning the room. The remote is easy to use too. It picks up most dust particles and pet fur from rugs and bare floors. It has a wet floor mopping pad which is so helpful. Surprisingly it picks up more than you think. The dust cup holds quite a bit before you have to empty it. The little side brushes help with collecting the particles. It can go under some furniture and along the walls. You have several floor patterns that it can be programmed for. It is very quiet too. Recharging doesn’t take long either. It can even be programmed to vacuum while you are away. Instructions are downloaded through the app.
My cats are very curious about how it moves about the rooms. So much fun to watch them.
I really got a great bargain for this robot vacuum on Amazon.
(I found that if you have clutter on the floors or cords under furniture you should remove and secure them before vacuuming.) It will find a way to go from floor to area rugs once it maps out the area.
I am still learning the functions in the app👍🏾👍🏾😃

Piece of junk
Color: White
So many problems with this device. I have a one bedroom apartment with one bathroom and no carpet so it's all hardwood floor. You would think this device would be able to vacuum the entire place without problems right? I think it intentionally looks for places to get stuck. For instance I have electrical plugs underneath my desk pushed against the wall, and somehow it managed to get stuck in them. So I had to block that area with a box. Then it got stuck going over my bath mats. So when I vacuum I have to put them into the shower. Then somehow it managed to get stuck in a little area by the island in my kitchen. So I had to put a roll of paper towels there so it wouldn't go into that area. Then it got stuck under the wheels of my desk chair. So I had to block that area. One night, even though there's a big table on the side of my couch to block it, it figured out a way to get behind my couch and then stopped. It took me two days to find it. And that's the other thing. it doesn't have enough power to clean an entire one bedroom apartment. So even if it doesn't get stuck, I will find it in the middle of the floor with the battery drained.
When I watched it I noticed that it will bang something and then it'll keep banging it a few times before moving on. And by moving on I mean it'll move 6 in and bang there a few times before moving on again. That's probably how it got stuck under the island. It couldn't fit the first time, so it kept pushing until finally it got jammed in there. I must say, however, it is amusing when it bangs into my foot and doesn't give up and tries to climb over my foot.
So although I bought this thing the end of November, I was in the hospital and wasn't able to start using it until the third week in January. After a couple of weeks I wanted to return it, but unfortunately I can't, because the window to return it ended January 31st.

Not too shabby
Color: White
I was skeptical but I read the reviews before purchasing. I had a $500 Roomba previously that worked six months then died. Using the warranty on those is almost impossible. So I took a chance. Cons: will fling itself down ledges and stairs. Like any robot cleaner, hates cords and plastic bags. Gets stuck now and then. You need to rinse out dust filter each time. Pros: runs a LONG time. Picks up all the dust and hair my Roomba did. Much cheaper. Has an app that you can supposedly program. Not too noisy. Beeps if it needs help. Charges well. Cats dig it. All in all I would buy one again. Robot vacuums are not for grime, they are for dust, hair, bits of cat litter. Keep that in mind. But in keeping your floor free of cords and debris that might trip it up, it helps you to be tidier overall.
