I love my first robot. It is a workhorse! It does not move haphazardly like some of my friends' vacuums. This robot is methodical. Easy to program. It goes straight to the scheduled room. When it meets a wall it moves over maybe 6" and returns on a parallel path making lovely, even vacuum path marks across the room's carpet. I bought this model because it is shorter and can reach under couches and dressers. Because it is so slim, the lidar technology is installed on the sides of the vacuum instead of on top. I imagine the top camera may turn independently to orient itself whereas on the slim model, the whole machine has to turn this way and that, when lost, to collect info from all its cameras before understanding its location. It takes a bit longer to get it's bearings but for me, it's worth the trade off. Mapping is a bit of a learning curve but I am amazed at just how accurate it is. Customer service is friendly, helpful and prompt. Just have your model and serial number ready before contacting. Rooms need to be cleared of obstacles. We broke the house into sections. Wednesday it is scheduled to clean the master suite Thursday it cleans the office and mancave. On Mondays it is scheduled to vacuum the dining, kitchen and living rooms. We move all the dining room chairs so it can has a clear path to concentrate on the crumbs under the table instead of navigating and circling 28 legs. On Fridays it recleans the dining room, kitchen and high traffic hallways. Because it does not do the entire house at once I cannot testify to battery life. It always has plenty of charge for the daily task unless it gets stuck. Suction is awesome. Cords need to be corralled, bath mats, waste baskets and laundry hampers need to be cleared from the scheduled paths. Last week the Roborock sucked up a low hanging Capri leg tie in the walkin closet and was stopped cold. The app on the phone tracks every move and helped us locate the robot when we realized it wasn't docked and charging. We have a second floor, so 2 maps. I carry the vacuum upstairs, click on the second map. When done, it is a little confused about how to return to the dock. The easiest way to reorient it is to place the robot just in front of the dock, click on map 1 and command it to return home. It turns around for a few seconds until it understands it's location, then backs in and starts charging We have been using it for 5 months and our house is cleaner than it has ever been when depending on me to get motivated. It's a lifesaver, a back saver and a time saver! You do have to check it periodically to make sure there are no blockages (such as a wayward post it note that has blocked the intake), the lidar lenses need dusting, and the filter needs to be rinsed every once in a while. Only two cons I can think of: 1. I don't need the mopping feature because some of our floors are very sensitive to water. It is hard to find a robot without that feature any more! The robot's dock is always displaying a red light because I don't fill the water tank which was a little disconcerting at first. 2. I named it Bella but it will only answer to Rocky.

Summary: I replaced a ~$400 shark robot vacuum with this one after doing a ton of research. I am more than happy with my purchase. Vacuum works very well on tile and carpet, and the mop does a good enough job (equivalent of a light swiffering). The app works wonderfully, and the vacuum fits under my cabinets. Highly recommend!!!Pros:+ Fits under my low entertainment system and kitchen cabinets. Neither of my last 2 robot vacuums could do that.+ Did a good job of mapping. Was able to identify correctly different surface types (carpet vs hard floors), furniture, and other objects. It did struggle with a standing mirror on the floor (it thought it was a door to another room), but I can't really hold that against it.+ Does a good job vacuuming up most debris and dirt; like all mop/vacuum combinations, it doesn't vacuum up hair quite as well as a vacuum only (I think the hair gets stuck in the mop pads?)+ Mops pretty well. Robot mops are generally just "okay" at mopping; it's just water and scrub pad, so it doesn't work much better than a moderate "swiffer". That said, it works well, and it has never tried to mop a carpet.+ It gets the edges of walls/furniture/cabinets very well when mopping.+ App is extremely good, definitely stronger than many other brands. There are a lot of detailed controls, as well as extremely detailed run maps, information about objects it has identified, and very flexible scheduling features.+ It gives VERY GOOD error messages. If there is a specific thing wrong - for example, a sensor is dirty, the error message will say "a sensor is dirty" both via the vacuum speaker AND the app. If you open the message in the app, there will be a diagram and instructions on how to clean the sensor. SO HELPFUL.+ It gives the right number of error messages. I am not constantly being bombarded with messages like "obstacle avoided" . It only tells me about things I need to take action on.+ It looks sleek (for a robot vacuum).Cons:- Gets hair tangled around the brush roll, but this is a problem for all robot vacuums. It's not much worse than my last vacuum, but it is probably the thing that requires the most maintenance on the vacuum.- Requires a bag. I really liked that Shark is a bagless system, and I really loved that. Having to buy and replace bags sucks, and, honestly, it feels "old".- It does eat thinner cables if you are not careful. It will avoid most "normal" cords (e.g. the cord on a lamp or an surge protector), but it struggles with the narrow (and long) cables used for most phone chargers. It has eaten the 6ft USB-C cable by my bed a couple of times.- This is nitpicking - I hate that I can talk directly to my vacuum. I don't need my vacuum to be constantly listening to me. The vacuum absolutely should be able to connect it to an Amazon Echo/Google Home, but why in the world would I want to speak directly to my vacuum (and only my vacuum)? Who is thinking "gee, my life would be SO MUCH better if only I could give JUST my vacuum verbal commands to do a very limited set of actions? Actions that could be controlled more easily and with more detail via the app, which does not require I be within speaking distance of my vacuum?" The feature is dumb. It's not anywhere near a deal breaker, but I really hate that someone wasted time and money on this feature (which I'm sure contributed to the overall cost of the vacuum).
