If you want a robot vacuum that empties itself, the real question is not just which one cleans well, but which one fits the way you actually live. The Roborock Qrevo, Roomba Plus 405, and Shark AI Ultra take three different approaches. Roborock leans into high suction, anti-tangle brushing, and obstacle avoidance. iRobot pushes the convenience angle with a 2-in-1 design and AutoWash Dock. Shark keeps the pitch simpler with self-empty vacuuming, voice control, and a large-capacity base.
My short take: the Roborock is the strongest all-around pick if you want the most complete blend of vacuuming and mopping features, the Roomba Plus 405 makes the most sense if dock-assisted mopping convenience is your top priority, and the Shark AI Ultra is the one I would choose if you want a self-empty robot vacuum without paying for mopping features you may not need. Each has a clear lane, and that makes this comparison easier than it first looks.
Roborock Qrevo Review
The Roborock Qrevo is the model here that reads most like a premium all-rounder. Its headline advantages are 8000Pa suction, anti-tangle brushes, smart obstacle avoidance, and vacuum-and-mop functionality. That combination gives it the broadest appeal of the three if you want one machine to handle daily debris pickup while also covering hard floors with mopping.
What I like most is the balance. Strong advertised suction matters if you are comparing premium models side by side, and the anti-tangle brush design is especially appealing for homes that deal with long hair or constant pet shedding. Smart obstacle avoidance is another practical edge because it suggests less babysitting during runs. The tradeoff is simple: if your priority is specifically dock-assisted mop care, the Roomba Plus 405 has a more obvious convenience pitch there. Best for buyers who want the strongest spec sheet on suction, a vacuum-mop combo, and anti-tangle brushing in one package.
iRobot Roomba Plus 405 Review
The Roomba Plus 405 is the self-empty robot for shoppers who care most about mopping convenience. It is a 2-in-1 vacuum and mop with an AutoWash Dock, dual spinning mopping, and smart, fast mapping. If your floors are mostly hard surfaces and you want a robot that feels built around regular mop use instead of treating mopping as an afterthought, this model has a very direct appeal.
The biggest reason to choose it over the Roborock is that dock setup. AutoWash Dock is the kind of feature that will matter more in daily use than in a spec chart if you plan to mop often. The tradeoff is that its product title does not make the same suction-power claim as the Roborock, and it does not call out anti-tangle brushes. So while it looks like the cleaner buy for mop-focused homes, I would still lean Roborock if you are more concerned with raw vacuuming emphasis and hair management. Best for buyers who want a true vacuum-and-mop combo with a dock that is clearly designed around making mopping more convenient.
Shark AI Ultra Review
The Shark AI Ultra takes the most straightforward approach in this lineup. This is a self-empty robot vacuum with Matrix Clean Navigation, home mapping, voice control, and an XL self-empty base with a 60-day capacity claim. That makes it the easiest recommendation for people who want automated vacuuming first and do not want to pay extra attention to mopping features.
Its biggest limitation in this comparison is also what keeps it simple: this is the vacuum-only option. If you want mopping, you should move on to the Roborock or Roomba immediately. But if you only want a self-empty robot vacuum for routine dirt, dust, and pet hair pickup, Shark keeps the message clean and practical. Voice control is a nice bonus, and the 60-day capacity claim stands out if fewer trips to the base matter to you. Best for shoppers who want a simpler self-empty vacuum with voice control and no need for a mop system.

Main Differences
The biggest split here is mopping versus vacuum-only design. The Roborock Qrevo and Roomba Plus 405 are both vacuum-and-mop machines, while the Shark AI Ultra is strictly a robot vacuum. That alone will eliminate one option for a lot of shoppers. If you expect your robot to handle sticky footprints or routine hard-floor wipe-downs, Shark is not the right fit. If you only care about automated vacuuming, Shark becomes much more compelling.
The second major difference is how each brand frames convenience. Roborock emphasizes high suction, anti-tangle brushes, and obstacle avoidance, which makes it feel like the best balanced performance play. Roomba Plus 405 emphasizes dual spinning mopping and an AutoWash Dock, which points more directly to mop-focused upkeep. Shark emphasizes voice control, home mapping, and a large-capacity self-empty base, which makes it feel like the simpler ownership experience for vacuum-only cleaning.
There is also a clear difference in how much confidence I would place in each product's specialty. For hair handling and stronger vacuuming credentials, Roborock has the strongest title-level case. For frequent mopping, Roomba Plus 405 has the clearest argument. For buyers who just want a self-empty robot vacuum with smart navigation features and a large-capacity base, Shark is the easiest no-nonsense option.
Final Verdict
If I had to pick one overall winner, I would choose the Roborock Qrevo. It is the most complete package here, with strong advertised suction, anti-tangle brushes, smart obstacle avoidance, and vacuum-and-mop capability. It is the safest recommendation if you want a premium self-empty robot that does a bit of everything well.
For mopping-focused shoppers, I would point you to the Roomba Plus 405. The AutoWash Dock and dual spinning design make it the most appealing choice if mop convenience is the feature you will care about every week. And if you want the simpler self-empty vacuum option, the Shark AI Ultra is the clear pick thanks to its vacuum-only focus, voice control, and 60-day capacity claim. Choose Roborock for the best all-around balance, Roomba for the strongest mopping angle, and Shark for straightforward self-empty vacuuming.
