This robot vacuum and mop was already a bargain, but a 56% discount makes it better

The Yeedi M12 Pro+ is now on sale for $400, a 56% discount for one of the best midrange robot vacuum and mops available.

Robot vacuum makers have been outdoing one another recently, launching stronger and better vacuums than the competition in quick succession. Roborock launched its flagship S8 MaxV Ultra with a mighty 10,000Pa of suction power last year. Just days later, the Yeedi M12 Pro+ won it, only to be outdone by the $1,900 Dreame X40 Ultra and subsequent Roborock vacuums in 2025.

The Yeedi M12 Pro+ gave me everything I’ve ever wanted but didn’t get from earlier versions of the Yeedi robot vacuum and mop combos. A hands-free two-in-one robot, the M12 Pro+ features 11,000Pa of suction power, a self-emptying dustbin, self-washing extending mop pads, a V-shaped roller brush to prevent hair tangles, and a spot-cleaning feature.

The charging dock — where the robot’s battery is charged, the dustbin emptied, and the mop pads washed and dried — is more compact than some competitors, including the Roborock S8 MaxV Ultra.

The suction power is evident as the robot travels across my home, where my family of five and a very hairy dog live. No crumb or hair is challenging for the Yeedi M12 Pro+, as it effortlessly picks up every morsel or paper clipping. 

I wish it performed better in obstacle avoidance when approaching random items on the floor. I can’t always pick up every little thing my kids toss on the floor or whatever stick my dog drags in through his doggy door before sending my robot out to clean, so object avoidance is a key feature for me. It is also important to me to be able to run my robot vacuum and mop automatically according to a schedule.

This M12 Pro+ robot got its roller brush stuck a few times on larger papers that it couldn’t handle, like sticky notes and protein bar wrappers, items that I would’ve hoped it avoided.

Because I like a set-it-and-forget-it solution for floor cleaning, having my robot eat and choke on random pieces of mulch or small toys is a deciding factor for my robot vacuum and mop. Mopping performance is another one. 

My home has mostly hardwood floors, with some tile and area rugs, so I need a good-performing robot vacuum and mop. Because my kids spill things and my dog walks in with muddy paw prints, I can’t just have any robot mop — I need one that picks up the mess between deep cleanings.

Yeedi’s robot vacuum and mop performs rather well for a $899 unit, and it even has a great mopping feature that I haven’t seen in midrange robots: TruEdge adaptive mopping, which extends the mop pads to corners and edges to clean in places where the robot can’t fit. The mop pads can retract automatically to avoid obstacles while mopping close to the edges.

I enjoy watching the M12 Pro+ make its way across my floors, extending its mop pads and cleaning much like a person would if they were using a microfiber towel on floors. The dirty and clean water tanks are huge, at 3.5-liter and 4-liter capacities, respectively. 

When the robot covers carpets or rugs to keep them dry, the mop pads automatically lift about 9 mm. I prefer a larger margin because the Yeedi Cube’s mop pads, which go up by 8mm, would constantly get the medium pile on one of my carpets wet and dirty. For comparison, other robots that have never dirtied my rugs include the Eufy X9 Pro and Eufy S1 Pro, both lifting their mop pads 12mm, and the Roborock S8 MacV Ultra, which lifts its mop 20mm.

The Yeedi M12 Pro+ effectively wet my area rug when set to vacuum and mop simultaneously. I wash my rugs at least once each quarter, so this is a small issue for me, but it could be a bigger issue for others. This only happened with the medium-pile rug, not the short-pile rugs in the entryways. The app allows for virtual boundaries, which worked very well after I set them up. 

The cleaning sink in the charging station detaches completely by pressing the two red buttons on the side, making this the easiest-to-clean base I’ve seen. Although you can run a self-cleaning feature on the app, detaching the sink where the mop pads are washed is very handy, as that area gets disgusting quickly.

ZDNET’s buying advice

The Yeedi M12 Pro+ is a standout midrange robot vacuum and mop at $899. There are some setbacks, like the lower 9mm mop lift on carpets and the fact that it eats objects larger than it can handle, but the many positives outweigh the negatives.

I’d go as far as to say that the M12 Pro+ and charging dock both perform like a $1,500 robot and mop combo. These robots are getting more expensive with each new model, so getting the chance to snag a top-performing, self-cleaning robot vacuum and mop for $400 is a great deal in this market.
