Roborock S6 Pure Robotic Vacuum & Mop w/ WiFi & Alexa Control (Black or White) Expired

I have a 3-floor house, and I think iRobot i3 or 960 doesn't support multi-floor mappings, how about this one?

Yes this supports up to 3 maps to be saved.

That Roomba doesn't have LIDAR navigation and mapping features. Only you can decide whether that's worth $90 to you, but if you have any but the simplest small apartment, you'll like that feature a lot.

Can this auto-charge, I think YES? (Just ordered one)

These are good questions. There is no single answer. Depends on your needs and desires.The only strong recommendation I'll make is not to bother with the mop, because you have hardwood floors. I could see it on tile, but as you noted they just drag water across your floor, and that's not good for hardwood.

IF you want a simple, reliable robot that's going to clean the whole floor every time, than the i3 fits that bill. If you have space to dock one on each floor, and you just want to buy two and set them on auto pilot and clean everywhere once a week, then you'll both be happy with the i3+, or even with a lower priced model like the Roborock E4 that doesn't have laser mapping but does use infrared to clean in a logical pattern.

IF you want the more sophisticated mapping features, then I recommend the Roborock S4 Max (or this S6 Pure deal -- just don't install the mop). I really love the technology. Once it's mapped your house, you can have different schedules for different rooms, and you can do thinks like say "Hey Siri, vacuum the kitchen." and it gets to work. I spilled some powdered sugar this morning and just opened the app and told my Roborock to clean that spot (Didn't have to go get the robot.). It's adding technology. The multi-floor mapping feature is also excellent, though it is definitely a compromise vs. having robots docked on each floor (Obviously, it can't clean rooms on the "other" floor automatically. You have to carry it there, then tell it what to do, but once there, it can clean rooms selectively etc.).

Some people LOVE the self-emptying bin. I personally don't get it. Instead of emptying a simple dust bin, you're buying bags and emptying bags (albeit much less frequently). Also they advertise that feature as "don't think about vacuuming for a month at a time," but I don't think I'd want to go a month without looking under the vac for things like long hair, strings, twist ties or papers that may have wrapped around the roller or clogged the intake. However, I don't have a house full of pets shedding all over the place and filling up the dustbin daily. I think those are the people who like the self-emptying bin.

As I mentioned earlier, the S4 Max and the S6 Pure are functionally pretty much the same vacuum. The difference is the S6 Pure's basic mopping functions. Since the S4 Max is in short supply and not on sale, you could buy the S6 Pure and just not install the mop.

yes it does. I did a lot of research on this model and ended up going with this one based on all of the positive reviews. There was another model that was on sale from Coredy but decided not to get that one after watching a video were they bundle gift cards for positive reviews.
