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.
