I highly recommend it
Color: White, Size: D20Plus, Color: White, Size: D20Plus
This is an excellent product and I am very happy with it. The suction power is strong , The automatic station makes cleaning almost hands-free, which is very convenient. Navigation and mapping are accurate, and it moves around furniture smoothly. It handles daily dust, dirt, and pet hair very well. Setup was quick and the app is easy to use. Overall, this robot saves a lot of time and works reliably every day. Definitely worth the purchase

Really nice and affordable vacuum!
Color: White, Size: D20Plus, Color: White, Size: D20Plus
I’ve been looking to upgrade my vacuum robot for a while. I came across this vacuum, it is affordable and comes with the features that I’m looking for. The strong suction, hair detangle brush (critical if you have long hair) and easy mapping. It honestly made daily cleaning so much easier. The suction power is seriously impressive. It picks up dust and crumbs and I love how it auto emptied the dust bin. Also I have hard floor at home and I’m loving the mopping function. I love how I don’t have to vacuum and mop the floor by myself anymore! Would recommend this robot to people that are looking for an affordable option!

Decent vacuum/mop for the price
Color: Black, Size: D20Plus, Color: Black, Size: D20Plus
We have had this vacuum for a couple of months now and can now give it an honest review. The good: cleans well, good suction power, durable, manages changes in floor height fairly well, attractive (for a robot vacuum), programmable, great mapping The bad: noisy, muffled voices, cumbersome to program initially, app is not the most user-friendly, does not like rugs with a higher nap. Some tips: 1) If you have pets, be cautious of the cleaning solution. Make sure it's pet safe. 2) For pets and children- Remember to pick up any toys before the cleaning cycle begins. The vacuum will try to eat smaller, flat or string toys, and you will end up with a wrapped brush notification. 3) When mapping for the first time, remember to close doors to any rooms or exterior areas you do not want vacuumed or mopped.

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!
