原文：This is my first robotic vacuum and I wasn't sure what to expect. I'm incredibly pleased to report that it performed better than I could have expected.Most of the reviews and demo videos I've seen are for small apartments or well-kept Ikea demo houses. I set the D7 loose on my 1,900 square foot firs
t floor with lots of irregular edges and obstacles in the way. It navigated them skillfully. I have four barstool chairs at a kitchen breakfast area and the D7 scooted in between each chair and wedged itself between the legs to clean as well as it could. It took two runs and ~3 hours (plus 90 minutes to recharge halfway through) to clean the floors on eco mode, which it turned on to do the initial mapping.During the run, it never once got stuck under anything and surprised me at how easily it got under the couches and chairs in my living room, office, and media room. The only thing it couldn't get under was a particularly low entry table. I had to empty the bin once during its run (cat and dog hair) and remove a sock and a USB cable that managed to get picked up, but that's a user issue. The noise level on eco is just a bit softer than its turbo mode which itself is pretty loud but not unbearable.While watching it go, I became worried a few times when it would do half a room or ignore an area behind a chair or under a shelf, but the D7 always came back and finished the job. My floors are almost all hardwood with a bit of tile in the laundry room so it didn't go over any carpets, but I can say that it worked amazingly on wood. I tested out the pause/resume function and the return to base and both worked just the way I'd expect. It does a cute little wiggle when docking itself, which I found particularly amusing. The floor plan reports on the app are nifty to look at and it did an super good job at recreating my house. I can see all the little dots where solid objects were (couches, table legs, etc.) and each room is more or less true to accurate dimensions. I wish I could label the rooms and tell Neato to go to a specific area, but maybe that's coming in a future release.Anything that it drove over was picked up and the only places left dirty were the very corners of the room, which it got close to but never quite reached. If I added all the corners up, it would be less than a square foot of space that was missed. Sometimes it's a bit over sensitive when detecting objects, like a low hanging drape that it could have easily pushed aside (I did not have the 'careful' mode enabled) but I suppose it's better to be on the safe side.After only a few days of use I can't say that I have a complete picture of how the D7 works, but the first few days of ownership make me feel completely justified in spending the money on the D7. Its continued performance probably relies on proper maintenance and frequent cleaning of the filter and brush, but that's a few minutes that I'm happy to spend for the quality of this little guy.

译文：这是我的第一个扫地机器人，我不知道会发生什么。我非常高兴地评价说，它的表现超出了我的预期。
我看到的大多数评论和演示视频都是针对小公寓或维护良好的宜家演示屋的。我把D7放在我那1900平方英尺的一楼，上面有很多不规则的边缘和障碍。它能巧妙地进行导航。我在厨房的早餐区有四张吧台椅，D7在每把椅子之间快速移动，把自己挤到两腿之间，尽可能地清洁。在节能模式下它清理地板需要2次运行和大约3个小时(加上中途充电需要90分钟)。
在清理过程中，它从来没有被任何东西卡住过，我很惊讶它能如此轻易地钻到客厅、办公室和媒体室的沙发和椅子下面。它唯一无法进入的就是一个特别低的进料盘。我不得不在它工作时清空垃圾桶(猫和狗的毛)，并移走一只袜子和一条USB线，但这是我的个人原因。在节能模式下，噪音比涡轮增压模式稍微好一些，涡轮增压模式本身就很吵，但并非无法忍受。
当我看着它开始工作的时候，有几次我都担心它只会清扫半个房间或者忽略椅子后面或者架子下面的区域，但是D7总是完成任务回来。我的地板几乎都是硬木做的，洗衣房里有一点瓷砖，所以不是所有地方都铺上地毯的，但我可以说，它在木头上的效果非常好。我测试了暂停/恢复功能和返回功能，它们的工作方式都和我预期的一样。它在对接时做了一个可爱的小摆动，我觉得这特别有趣。该应用上的平面图报告看起来很漂亮，在清扫我的房子方面做得非常好。我看到所有家具(沙发、桌腿等)和每个房间都或多或少被精确的计量了。我希望我能给这些房间贴上标签，并告诉Neato去一个特定的地方，但这可能会在未来的版本中出现。
它经过的地方都被打扫干净了，还剩下的脏的地方就是房间的各个角落，它很努力地靠近，却永远也够不到。如果我把所有未清扫的角都加起来，只有不到一平方英尺的空间没有被清扫到。有时，当探测到物体时，它会有点过于敏感，比如它碰到低垂的窗帘时本来可以很容易地将其推到一边(我没有启用“小心”模式)，但我认为是出于安全考虑。
在仅仅使用了几天之后，我不能说我对D7的工作原理有一个完整的了解，但是最初几天的所有体验让我觉得把钱花在D7上是完全合理的。它性能的持续性可能还要依赖于适当的维护和对过滤器和刷子的频繁清洗，但为了小家伙的质量，我愿意多花那几分钟。
