After some grumbling about an 8% price drop 3 days after I ordered my D7 and getting no satisfaction from that great e-store in the sky, I decided that I still wanted to be one of the first on my block to own a Neato D7 no matter and finally opened the box after much debating a return. The D7 works great. Might have more to add later but here goes for now....My main complaint from reading the manual is that you can have only one Floor Plan for now. You can only start from the charging base and do the whole Floor Plan at once if you want to use the No-Go lines (after the 1st mapping run). So you can't map your 2nd floor or the basement or a separate far-flung area of your house without losing your original map and its No-Go lines. If you start the bot in a room using the machine button to do just that single room, you have to use physical boundaries or magnetic strips to contain the bot. No-Go lines don't work without starting each run from the base and using the map.Update 4/2/18: RE: attached map. See end of review. Unusual(?) arrangement of dining room furniture makes D7 go relatively bonkers...But other than that, the D7 botvac pretty much lives up to its promise. Very simple to set up and operate. Great out-of-box experience. My wife, a "do-we-really-need this?" person, remarked, "It's beautiful" when I took it out of the box. She was impressed that if fit under the rungs on our kitchen chairs, our side tables and their lower shelves in the living room, etc. (it has about a 4-inch clearance)It spends a good part of the 1st minute or two of its first run looking all around with its LIDAR. It's not quite as one-and-done methodical as I expected and seems to go over some areas more than once (in a methodical way), which can be good to make sure it does a thorough job, especially with its side brush kicking up dirt along baseboards on a slippery-sliding tile floor where things might get hockey-pucked around. On its Turbo setting, it's not all that loud compared to a regular canister vacuum (71 db? - still scares the cat) but it certainly gives things a good bump from time to time so probably the Extra Care setting is a good idea around anything you value a lot (outcroppings in baseboards seem to be hard for it to see, e.g. the oven area juts out more than stuff to either side and it wacked into the protruding baseboard extensions there). OTH, one of our kitchen island cupboard doors was ajar and as it was steaming along the baseboard toward the slightly open door, I thought, "Uh-oh! It's going to clobber its laser turret on the open cupboard door!" However, the bot saw the open door in its path, whose bottom edge was easily 3 inches above the floor, and deftly steered clear of the open door. It looked like it could easily go under the legs of our kitchen table (a full-size old dining room table drafted for duty in a kitchen nook). The legs swoop down to the floor in a convex downward curved tripod with plenty of space in the center for the bot to go through but for some reason, the bot refused to run through either set of tripod legs holding up either end of the kitchen table. It seemed to go into each of the 3 open spans between the legs (imagine 3 sides of a triangle with the legs at the apexes) and back out without attempting to go through the middle of the triangle, although there appeared to be plenty of room for such a maneuver. Perhaps such caution explains why the bot didn't get stuck anywhere in our kitchen although there were some opportunities to do so, like possibly wedging itself between the lowest curved parts of the table legs and the floor.The instructions recommend placing the charging base on a hard floor. However our bot did not avoid its charging base, rammed into the base while chugging along a baseboard sideways toward it, and pushed the base out of place and around a corner. So some sort of double-side tape or suction feet or similar might be a good idea to keep the base in place on a hard, smooth floor. The bot had no trouble finding and docking at its base after doing our kitchen and the map pretty accurately represents what it did and what it avoided. The wife thought the kitchen was pretty clean to begin with but her response after demanding to see the dustbin results was, "Oh, My God!" (I think that we now have a new D7 devotee in the family!). She was thoroughly impressed at how much overlooked cat hair the D7 found, probably because of places it managed to crawl under that are hard to get to with a canister vacuum using a long wand. Both the supplied magnetic barrier and the 3rd party Sun Tea Magnetic Boundary Markers Strip for Neato Robotic Vacuum Cleaner (13 feet long) worked well to contain the bot within the confines of our kitchen and back hall for its first test run.The ultra-performance filter and the side brush were pretty easy to clean with the provided comb (nice you get 2 extra filters with the machine but no spare side brush, unfortunately, and that's an expendable item - to be replaced ~once every 6 mo). My wife has very long hair and alopecia - so it's her lost hair and not the cat hair that tangles the spiral combo brush. But it's SO EASY to remove the brush and then run scissors along the brush grooves to snip hair tangles, then comb stuff into a waste basket easy as pie. Same with the ultra-performance filter. The mesh screen cover traps 100% of cat hair seemingly outside the pleated HEPA filter where the dirt and hair can be dumped out of the main bin and easily combed off the filter screen and then we have a pretty powerful 80's Hoover canister vacuum to run over the mesh screen that seems to suck all the dirt BACKWARDS out of the fluted main HEPA filter. So after collecting an amazing amount of dirt off our "clean" kitchen floor, the filter almost looks like new again after its brief first run and a good quick-and-easy cleaning with the comb and a canister vacuum upholstery brush.The Neato app says the bot vaccumed 217 sq. ft. of space in 22 minutes and only consumed 15% of its fully charged battery. It's nice that the app gives % charge for the battery. Until the Neato app provides the ability to break our large house down into several smaller maps and have No-Go lines separately for separate discrete areas of the house, I plan to run the D7 manually in discrete sets of rooms using physical barriers and magnetic strips and keep the bot between 20% and 80% charge to maximize the Li-ion battery life span (see the Android AccuBattery app and Battery University on getting the most life out of a Li-ion battery). It would be nice if Neato built more sophisticated charging control, such as used to maximize the life of electric vehicles, into the Neato app to get the most out of the botvac's battery. Most people do not need to do their whole house in one day from one map, esp. if it's up to 5,000 sq. ft, the max size the app allows, and it would be great to have an app that allows the bot to go about its work broken down into manageable parts without stressing the bot's battery to the max just to get the job done in one go in one day when bit-by-bit over several days, being kind to the battery in between, would make for more economical ownership..All in all, I'm a very happy D7 owner and I'll be even happier if the D7 lasts and lasts and lasts - I bought the 3-year Asurion extended warranty, which at $25 a year for years two through four of ownership seemed like a relatively good deal for an $800 item that has a bunch of electronics in it and is subject to wear-and-tear. If I have any maintenance problems, I'll come back and update my review.....Major Update to Review: I've now run my D7 in four separate runs in four different areas of my house: 1) kitchen and back hall; 2) large angled front hall interrupted by descending stairway, piano, doorway to bedroom, closet corner space with cat tree; 3) living room, crowded with furniture and lots of low spaces to crawl under with side tables, chairs, coffee table, and sofa; and, 4) large open family room, few walls, borders mostly low irregularly shaped objects or TV stand and bookshelf loaded with irregular, randomly spaced objects. The bot did great in every area except the large open family room. There it bizarrely kept coming back to a large ottoman in front of a sofa at least 5 or 6 times, if not more (I lost count), inching around the ottoman, digging, trying to go under it. First bout was just circling the ottoman 3 or 4 times nonstop but then even when it circled behind the sofa and went around it and should have discovered lots of new space it had yet to do, it would come back to the ottoman in this apparently trapped loop after circling the couch each time, and keep trying to go under the ottoman while going around it. In the second part of the run, after I had to pause the bot by pressing the Start button (I have always been manually running the bot since with the app it always wants to do the whole shebang and you can't break your house down into parts to do day-by-day, as I want to do), my D7 exhibited similar "loopy" behavior with a cat tree near a spring-loaded doorstop. Apparently it doesn't see doorstops very well at all, ignored an acceptable mount of space to go between the cat tree and the doorstop, loaded up the doorstop spring by trying to go along the baseboard, got pushed back and rotated a bit with each encounter. But again, even when it went off to other areas, it would come back to the cat tree doorstop areas as if it had never seen it before until after 3 or 4 tries it managed to progress on to other areas.Manual runs do generate a map of where the bot has been that show up in the Neato app. CORRECTION: Unlike what I said previously, navigation arrows down at the bottom of the Neato app allow you to back navigate even through previous manual runs that were initiated from the START button on the machine - all runs seem to be saved so far (you can also "share" the map in the ways that sharing is allowed on your device, e.g., I've been e-mailing the map of each D7 run to myself). But what the Neato app needs in addition to the room map with where the bot has been or not been, is a color-coded "HEAT MAP" option to display on the map of relatively how much time the bot has spent in each area. That way after a run any problem areas where the bot exhibits the loopy, stuck-in-a-rut behavior that I have described would be obvious to the user. Otherwise, if I had not watched the bot every minute, I would have only seen on the map in the app a "successfully completed" run, not the highly repeated "burrowing" attempts to get under the ottoman that might help wear out the bot and perhaps the rug around the ottoman in the course of many repeated runs over months and years.The other thing the large family room run showed is the bot did not seem to pause and resume where it left off. I wasn't running the Neato app for most of the early bot run. Decided to run the app to check exact % charge of bot battery. A warning that the dust bin was full flashed in the Neato app and the battery was at 35%. Pressed the Start button to pause the bot (since this is a manual run not directed by a pre-determined house map). Thoroughly cleaned the bot, recharged to 89%, with the app protesting the dust bin is missing (it had told me to clean it?!) and the bot beeping it protest during the cleaning part after it's pause. Finally I put the bot back in the exact same spot and orientation that I had paused it in its cleaning run initiated only by a Start button press. I expected the bot to remember where it had been, since it had never been turned off, only paused, and its run had been interrupted on advice from the app. The bot did mostly but not entirely clean the remainder of the large open family room, I think only based on the geometry of the location that I paused it at. But then after not entirely taking care of the remaining areas, it started recleaning the areas that it had already visited before I had paused it per app instructions to clean the dust bin.So hopefully the loopy behavior when encountering certain objects in a very large open room and the failure to remember exactly where it's been when paused from a manual run initiated from the bot using only the Start button to start and stop are just software problems that can be fixed by further updates. I see no reason to give the bot less than 5-Stars as its behavior in the other rooms was stellar but it did seem to go a bit bonkers in the very large family room (roughly 20 x 20 ft, few walls, mostly open areas leading to other areas of the house). UPDATE 4/1/18: Just during vacuuming, removing crinkled aluminum foil used on top of leather ottoman to keep cat away and removing spring-loaded doorstop solved "loopy" problems. Neato website says laser navigation can be confused by stray reflections from bright shiny objects ( hence the reason "anti-cat" Al foil was source of D7 ottoman disorientation). Still wish D7 handled doorstops better...Oops! One further update/warning. This is something ANY ROBOTIC VACUUM would probably handle poorly. In the living room we have a large, several hundred pound VERY thick wool rug in the center of the room over a wall-to-wall nylon pile carpet. Following instructions to tuck the rug fringe of the wool rug under to avoid the bot sucking it up in its roller leads to a 3/4 inch high curb between the top of the wool rug and the base layer of the nylon pile carpet. What the bot does and I'm sure any would do, is it gets one side up on the top of the wool rug "curb" and rides along that curb since it tends to work in directions parallel to room walls. Riding the curb has two bad effects. The curb is so high that the bot is nowhere near touching the underlying nylon wall-to-wall rug right next to the curb and also much of the weight of the bot may be on the top edge of the wool rug curb through the brush. I'm worried that as time goes by, the bot will scrape off a bit of the top edge of the wool rug curb (there was a frightful amount of wool rug color in the dustbin when done). I think the bot should be smart enough to recognize it's highly tilted and raise the wheel that's on the nylon pile carpet to level itself with the wool rug its other side is riding on or else the bot should be smart enough to see such curbs and either stay entirely on or off the curb to avoid the cleaning problem and rug wear problem that I see from having one side propped up on the edge of a covering rug curb. If the Neato D7's selling point is that it's a darn smart botvac, it ought to get smart enough to handle this vexing rug situation, which I'm sure just about any botvac would handle poorly without deep analysis of its environment. (and we're certainly not able to roll up or carry this very heavy, very big decorative rug out of the room just so a botvac won't encounter problems and I'm not going to manually drive a botvac around my living room, either).Update to Pausing D7 for Cleaning/Charging During a Manual Run: I had previously reported that hitting the Start button to pause the bot during a manual run initiated from the Start button (as the user guide says to do) causes the bot to forget where it was when you resume by hitting the Start button again, with the bot eventually starting to reclean areas it's already covered. I found out paradoxically enough (not mentioned in the user guide) that EVEN WITH A MANUAL RUN, YOU CAN USE THE APP TO PAUSE AND RESUME the D7 AND THE BOT DOES NOT FORGET WHAT IT'S DONE IN A ROOM and will clean only where it hasn't been when you hit the Resume button in the app. I also think it would help a lot in cutting out hair tangles in the side brush if the side brushes were made of some bright color, e.g. orange or yellow, because when trying to figure out what to cut to unsnare a tangle, it's very hard to tell dark hair from the dark side brush fibers that get all bent out of shape and twisted up into a tangle with the hair and other lint if the bot encounters a mess of it, e.g., couple foot long black hair from my wife! The black side brush fibers look great as a matter of style but they're a nightmare when it comes to disentangling black hair tangles.CORRECTION & Further Update 3/24/18: Discovered that the D7 does save a map of every run even when run manually from Start button & have corrected lines on that in review above. A little left arrow at the bottom left of the app allows you to review previous map runs. Also observed Neato D7 to go down along between toilet and wall to corner, where there was so little room that it seemed the bot would have to back out. Instead it repeatedly went forward and backward dinging the toilet and baseboards in the back corner behind the toilet until it had turned around. It would be easier on the woodwork, etc., if the bot were just programmed to back out of such situations. Again a "heat map" of activity or other report of struggling would help a user find problem areas in a run without having to watch the bot every single minute.Update 3/31/18: Have found that my D7 has problems with table-like structures that are very open underneath but have crossbars between the legs below the main body of the D7 WHEN THE D7 APPROACHES SUCH AN OBJECT FROM ITS LEFT SIDE. It seems the D7 laser sees lots of open space between the legs but since there is a side sensor only on the right side of the D7, the D7 can't see a very low impenetrable barrier on its left. One would hope after a couple of bumps the D7 would try another strategy but I've seen the D7 repeatedly vigorously bump very low crossbars on a Black & Decker worktable and a fine wooden coffee table a half dozen or more times each before it decided to move on. One would hope in a situation like this that the D7 after a bump or two would backup, rotate, and check out the object it's dealing with from its right side (and maybe they can put side sensors on both sides in the next version-maybe even low-level object sensors on the front!). I'm running the D7 in MANUAL mode (see 2nd paragraph of my review on map limits) -so my D7 is not going to be able to improve from its map history of encounters with such obstacles as Neato says the D7 does until Neato comes along and provides the ability to break a very large 2-story house down into multiple maps of manageable regions. Just seems like the bot should be smarter than it is in these crossbar encounters even when not using a map. Feedback sent to Neato....Update 4/2/18: Saved doing dining room 'til last (see attached map). Large table, 6 large chairs, side table, china closet. Pulled chairs out from under table for botvac access but to give D7 room to go behind and between chair and table legs in crowded small room, turned 4 of 6 chairs on 3 sides of room to a 45 degree angle to orientation of table and walls, china closet, etc. D7 spent a lot of time weaving around and bumping chair legs and table, did not negotiate room efficiently, revisited chairs and sidewalls it had already done several times, going off to far corners of room, covered room in very piecemeal, haphazard fashion. Normally covers about 10 sq. ft. per min, only covered 5.4 sq. ft per min in this room, perhaps because of many legs to negotiate, but certainly in part of because of its inefficiency in this unusual setting and redoing parts willy-nilly. Invite others to try similar and report in their review. Reporting to Neato. Still love D7. Stellar overall with modest prep in other rooms and easy solution is just to move chairs out of room to give bot free reign and not create unusual obstacle course or try with chairs not turned but better aligned to table spaces (see pix-bot is under one end of table). In fairness to bot, it did cover entire room very completely in end.Update 8/4/18: I encountered a pretty significant problem with the D7 when I tried to clean our very large open-walled family room with most of the central furniture and central accoutrements removed from the room. The D7 became very disoriented and vacuumed the 18 x 18 ft room 2.5x over before I had to force it to stop. I believe that this is the "large empty room" problem that Neato makes reference to in the FAQ on its website on the new multi-floor plan capability and the need to put the charging base starting point in a "mappable" location within 10 feet of a side wall or large furniture so that the D7 can recognize the uniqueness of its location in creating a second or a third multi-floor plan, which is now possible after the 7/30/18 firmware update. Seems to me that the need for side walls or large furniture within some distance like 10 ft also holds for other parts of a D7 run so I plan to add back "stuff" to our family room and see what is the minimum it takes to keep the D7 properly oriented (I had removed "stuff" to allow the D7 to thoroughly clean the whole carpet and suck up cat hair and dust that was hiding under furniture too low for the D7 to go under). I think Neato should offer users more details on the minimum requirements to keep a D7 properly oriented in very large open "empty" rooms and even offer (laser-reflective?) markers or pylons to help orient the D7 if one encounters the "large empty room" problem. Initially when I first just encountered this problem, I wrongly blamed the 7/30/18 firmware update and was about ready to throw the device out the window but then I put the D7 to work on the 2nd floor where it ran through a long, cluttered maze, skillfully and efficiently negotiated all sorts of obstacles, and returned to exactly where I had started the bot. So when we provided our D7 with enough junk and clutter in our house(!), the bot had no problem orienting itself VERY precisely!
