There are an absurd number of robot vacuums available today, but based on my testing of dozens of bots, just a handful of manufacturers are leading the pack when it comes to innovation, choice, and really good cleaning machines. These include Roborock, iRobot, and Dreame. Each has recently released new flagship models: the Roborock S8 MaxV Ultra, the DreameBot X30 Ultra, and iRobot’s Roomba Combo J9 Plus.
I’ve reviewed the Combo j9 Plus, and I still recommend Roombas if you’re looking for either a high-end robovac or a budget bot, in large part due to their repairability, ease of use, and reliability. But the competition is getting very good, and with iRobot’s future looking shaky following its break up with Amazon, I figured it was time for a deeper dive into its strongest competitors. Here, I pit the X30 Ultra against the S8 Max V Ultra to see which one is the best.
The Roborock S8 MaxV Ultra ($1,799.99) is a robot vacuum and mop with a charging dock that fills the robot’s onboard water tank, cleans and dries its mop pads, and empties its onboard dustbin. It features a whopping 10,000Pa of suction and a camera for obstacle detection and avoidance. Its mop vibrates up to 4,000 times a minute to scrub your floors and raises up to 20mm to avoid carpet.
The S8 MaxV has a new flexi arm that pushes its spinning side brush out further to get into corners better and a side mop that helps clean along edges. A new on-device voice assistant can take direct commands, so you don’t need to use the app or a third-party speaker to control the robot (although it works with Alexa, Google Home, and Siri Shortcuts). It’s also one of the first robot vacuums that will support Matter, although that feature hasn’t been turned on yet.
The DreameBot X30 Ultra ($1,699.99) has many of the same features as the S8 MaxV Ultra, including a charging dock that auto-empties, washes the mops, and fills the robot’s water tank, plus a camera for obstacle detection. It has 8,300Pa suction and uses dual spinning mop pads that it can automatically remove when it vacuums — my favorite feature. It can also lift the mops if needed (up to 10.5mm).
Uniquely, the Dreame can extend its mops out to reach baseboards and even under low furniture, as far as 4cm; this is surprisingly effective at getting up grime from edges.
I let these two bots battle it out in my home over 10 days, testing their cleaning prowess, mopping chops, navigation skills, and unique features — such as an arm and mops that do the splits. I also evaluated the design and usability of their multifunction charging docks and how well they meet their promise of hands-free cleaning. I put their companion apps through their paces, diving into all the settings and features these machines offer in their quest to clean your floors. Read on to find out which one came out on top.
While Roborock has redesigned its dock into something smaller and more aesthetically pleasing (it was the first to release a multifunction dock, and those early days were characterized by hulking monstrosities), it’s still one of the ugliest out there. Dreame, on the other hand, has perfected the stylish dock look, and while it’s bigger than Roborock’s, it’s much prettier.
Dreame’s dock is also slightly more functional. While both models will wash the mops with hot water and dry them with heated air, which helps deal with the smell and mess, Dreame has little wipers that clean the mop area for you, whereas Roborock’s mop tray needs manual cleaning. However, Roborock has the option to connect directly to your plumbing, doing away with the bulky water tank-look entirely. You do need to get a specific model for this, which costs $100 more. While Dreame sells an add-on kit to its existing model for this function, it’s only available in Asia. A North American model — the X40 — is coming later this month, but it costs nineteen hundred dollars.
Winner: Tie

Both models use lidar to map and navigate your home. They both mapped the house quickly and accurately and responded correctly to requests for room-specific cleaning and zone cleaning — meaning they didn’t get lost. These robots both have front-facing cameras for AI-powered obstacle avoidance, and they both nimbly avoided fake dog turds, socks, shoes, and bundles of cables.
