Excellent for vacuuming with a great app
Color: White, Size: D20Plus
This thing is just awesome. I gave her name and some googly eyes, and now she is my official cleaning lady. Does a great job with dog hair which was the main reason for the purpose. I was vacuuming all the time. I have hard floors and 3 dogs one of which is a golden retriever that sheds like crazy. The D20 does really great getting up the pet hair along with other stuff in the floor. I have a couple area rugs as well as thick mats in front of the front and back doors, and she does great on both. I definitely make sure to get up any cables or little things like door stops as she will get caught up from time to time. The app works great and does a good job of sending alerts when there is an issue. It lets you know if it’s hung up on something, stick on an edge and if the cleaners are tangled up underneath along with other things. It’s really easy to flip over and take off the brushes to clean them out and untangle them, and easy to put it all back together. You can also schedule her to clean any time of day / night and customize how it cleans certain areas. I prefer to let her run late at night while me and the dogs are sleeping, and she gets the house done in about 90 minutes and covers a lot of ground. She’s also surprisingly quiet for as much as she is picking up. If I’m already awake, I can hear her start to roll around upstairs. But I’ve never been woken up by her, nor have my dogs. I have never used the mop feature as I bought it only for the vacuuming. From what I’ve read it seems there are better options for mopping. But as far as vacuuming goes I am super happy with her! I was vacuuming 3-4 times a week and would usually mop every other week, if ai could get away with it. Now I vacuum and mop once every two weeks, and Dreame does a wonderful job keeping the place clean in between my bi-weekly cleanings. The D20 was a great purchase and a major time and energy saver for me!

Useless
Color: White, Size: D20Plus
Well so far unable to actually use it to see how it works. I have to split my wifi every time I want to use it. It won't charge even when it's on the dock. When I push "charge" on the app it comes off the dock instead of recognizing that it's already on it and proceeds to roam around the house looking for the docking station that it just left. If it can't even find the docking station while sitting on it how can it properly clean the house? I just bought this after returning a defective AirZeen model. Looks like Shark may be the only way to go. Starting yet another return. These are useless

Great Cleaning Power and Super Convenient
Color: White, Size: D20Plus, Color: White, Size: D20Plus
The DREAME D20 Plus Robot Vacuum and Mop works really well in my apartment. The suction is very strong and easily picks up dust and pet hair from both carpets and hard floors. I also like the self-emptying feature with the large dust bag, which saves me a lot of time. The mapping is accurate, and the battery lasts long enough to clean the whole place. Overall, it’s a great robot vacuum for the price.

I am very satisfied with the overall experience!
Color: Black, Size: D20Plus, Color: Black, Size: D20Plus
The suction power is really strong. Daily dust, hair and debris can be easily cleaned up, and the ground is obviously much cleaner. Although there are no pets at home, it is enough for daily cleaning.
What I like most is its self-dust collection function. The 5L large dust bag has a large capacity and can be used for a long time without dumping garbage. It is really worry-free. It is very friendly to people who do not want to take care of the machine frequently.
The drawing is very fast and accurate, and the cleaning route is orderly and will not collide randomly. The APP is easy to operate, and the appointment and remote control are very convenient.
Generally speaking, it is very cost-effective, time-saving and effort-saving, and worth buying.

Good Robot Vacuum
Color: Black, Size: D20Plus, Color: Black, Size: D20Plus
This robot vacuum is really easy to use and very smart. After one cleaning cycle, it can remember the size and layout of the rooms, and it also allows you to choose different rooms for cleaning. It cleans very thoroughly, and when it finishes, it automatically returns to the dock to empty the dust and recharge. It has truly saved me a lot of time and has become a very helpful assistant at home. It also runs fairly quietly, so it does not disturb daily life too much. For people who are busy and do not have much time for housework, it is definitely worth buying.
