tart with the 650, not this product (obviously) but to give a little context. The 650 is slightly smaller than the 870, it's pretty powerful and has a decent battery life. We set the schedule (which is very easy to do) for our 650 to begin patrolling at 9:15 am and let it get on with things. Each day we empty the bin and each day it refills it. The battery on the 650 lasts for around an hour, maybe 75 minutes. It's long enough for the robot to cover a few thousand square feet and pick up a full bin of dust and dirt. It's small enough to get under most items of furniture, sofas, tables, etc. We do have a few items that it can't get under, but I just move those once a week and let it get to work.
The 650 uses brushes and bristles, it works solidly, although you will want a few spares to swap out. Also, you will want replacement filters as they get dirty very quickly, no matter how clean you think your home is.
We have children and find that we need to go around each evening to make sure they've not left anything small on the floor, as the Roombas are indiscriminating and will happily suck up necklaces, toys and other items. On the plus side we've also found that telling the kids the robot is going to eat their toys is a great motivator to get them to clean up!
The 650 finds its way back to the dock most, but not all days. Probably twice a week we need to play 'hunt the Roomba'. Sometimes it wanders in to a room and accidentally shuts the door after it, resulting in one very clean room, an exhausted robot and dust everywhere else. In these instances we simply put him back on charge, give him a rest for a little while then set him loose again.

Overall the 650 is a good starter-robot, recommended for those wanting to dip their toes in to the robot market without splurging big bucks.

Now, the 870. Slightly larger than the 650, it has a larger bin, better (HEPA) filters and an improved guidance and sensor system. The 650 will hit walls and furniture with a solid bump, not so the 870 which has more of a delicate touch.
The 870 also has a slightly better battery life, I would say that it gets around 75 minutes on average, extending up to 90 if it's feeling particularly dedicated that day. The biggest difference, however, are the brushes - the 870 uses rubber brushers with no bristles, you would have thought that this makes it a worse vacuum than the 650 which employs a roller and bristle combination, but the opposite is true. Thanks to its improved vacuum power and brush system the 870 picks up dirt and dust like you wouldn't believe. In addition to the kids we also have 2 birds and a dog and every day our faithful 870 runs on his schedule (again, very easy to set up) and collects dog hair and dirt like a demon. He almost always finds his way back to his dock, probably 90% of the time.
The HEPA filter is great, but you will want additional filters to swap out as they collect dust very quickly. The new filters from iRobot are better than the stock ones that the Roomba comes with, and if you register your robot online with iRobot they will send you two extra filters for free.
The 870 also has a 'bin full' indicator, which is handy because the passage for the dirt to travel through to get in to the bin is smaller than in the 650. This is good because it increases suction and results in a more thorough clean, but bad because it's a smaller gap for dust to bottleneck in. You will want to empty this bin and clean out the filter every day to keep your robot running nicely!

Summary: We love both our 650 and 870. There are pros and cons to both. If you're not shy of spending money and you want a thorough clean, then stretch to the 870, it's worth it. If you're just exploring how our robotic friends will be helping us stay clean in future and want cleaner floors then the 650 is a perfectly good starting point.

让我们从650系列开始，并不是不是这个产品，但先做一下铺垫。 650比870略小，功能非常强大，电池续航能力也不错。我们为它制定了时间表（这也是很容易的），让我们的650在上午9点15分开始四处清扫，让它一直保持这个模式。我们每天都会清空垃圾桶，然后它又会重新装满。 650的电池可以用大约一个小时，也许75分钟。机器人需要足够长的时间才能扫完几千平方英尺的地方，扫起来了一整箱灰尘和污垢。它体积很小，可以清理干净大部分家具，沙发，桌子等。我们确实也有一些它不能清扫到的东西，但我只是每周移动它们一次，让它能够正常工作。

650系列的有刷子和刷毛，它质量很好，虽然你会想要换一些配件。另外，无论你认为自己家有多干净，你都需要更换过滤器，因为它们很快都会变得很脏。

我们有孩子，所以每天晚上都要到处走走，以确保孩子们没有在地板上落下任何东西，因为Roombas不分青红皂白的哈哈，会愉快地把项链，玩具和其他物品都扫走。另一方面，我们也发现，告诉孩子们，机器人会“吃”他们的玩具是一个很好的理由，可以让他们自己清理！

650系列可以自己找到最多的路径，但不是所有的时候都可以。可能每周有两次左右，我们需要去“寻找Roomba”。有时候它会徘徊到一个房间，不小心门被关上，然后房间会被搞得很干净，留下一个耗尽电力的机器人和其他还没来得及扫完的灰尘。在这些情况下，我们只是把他交给负责维护的人，让它休息片刻，使它放松。

总的来说，650是一个很好的起动机器人，对于那些只想把自己的一部分精力投入机器人市场的人来说，建议不要浪费大量的资金。

现在的870系列略大于650，它有一个更大的箱子，更好的（HEPA）过滤器和改进过的制导和传感器系统。这个650会很彻底的走过墙壁和家具，而不是870只是轻轻的扫过。

870的续航能力稍好一些，我想说的是它可以使用75分钟左右，如果某一天它使用的比较好的话，可以延长到90分钟。然而最大的区别是刷子--870使用不带刷毛的橡胶刷子，你会认为这使得它比使用滚筒和刷毛组合的650系列要差劲一些，但情况正好相反。由于它有着改进了的的真空力量和刷子系统，您不会相信870系列还可以拾起污垢和尘土。除了孩子以外，我们还有两只鸟和一只狗，每天我们很方便的在870系列的日程安排里设置好（再次声明，非常容易设置的），可以让它清洁狗的头发和像恶魔一样的污垢。他几乎总是找到自己的路回到最开始的地方，可能绝大部分的时间都可以找到的。

HEPA过滤器非常棒，但是您将需要经常更换过滤器，因为它们很快就会收集好灰尘。来自iRobot的新过滤器比Roomba自带的过滤器更好，如果您使用iRobot在线激活机器人，他们会免费向您寄出两个额外的过滤器。

870还有一个“满箱”指示器，这很方便，因为污物进入箱子的通道比650的更小。这很好，因为它增加了对赃物的吸力，也可以有更彻底的清洁，但也不是很好，因为收集灰尘那里有一个小的瓶颈。你会想清空这个垃圾箱，所以要每天清理过滤器，以保持你的机器人运行良好！

总结：我们喜欢我们的650和870.两者都有优点和缺点。如果你不吝惜花钱，而且想彻底清洁，那就使用870的吧，这是值得您花钱的。如果您只是想试试我们的机器人朋友将如何帮助我们保持清洁，并希望用来清洁地板的话，那么650是一个非常好的体验。

for quite some time, but never did I think that vacuum would be a Roomba.

Truth be told: I always thought robot vacuums/sweepers were a bit of a gimmick, something for tech-junkies or, well, the lazy. So when it arrived in the mail, I opened it with both skepticism and cynicism, thinking, if nothing else, the Roomba would serve as a fun new torture device for our cat, Sherlock. As much as it pains me to admit, I am now eating crow. The Roomba 870, despite a few limitations, is an incredible appliance and I will (probably) not speak ill-ly of them again.

My home set up: one-bedroom apartment, about 700 sq ft, tile in the bathroom and kitchen, carpet and throw rug in living room, bedroom and closet. One short-hair domestic cat who loves to shed, and one imported wife with long black hair, who also loves to shed. After spending some time with it, here is a list of Pros and Cons for owning the iRobot Roomba 870:

PROS:
* Solid construction. The Roomba is built like a tank, but has soft edges, so if it does collide with an object (which rarely happens anyway), no damage will be incurred
* Surprisingly quiet. I can still hear the TV/stereo/conversation while the Roomba is running
* No more spinning brushes that get clogged with debris! I didn't realize what a pleasure this would be (specifically, it doesn't choke on the tassels at the ends of the throw rug! Genius)
* Fairly intuitive, easy setup. I'm certainly not ignorant of technology, but for time's sake, I'll always prefer simple programming. Can set up multiple, scheduled cleanings with relative ease
* Long battery life and self-charging. The battery has yet to die mid-cleaning, as I don't have a ton of square footage, but this is still a a great feature. The Roomba will find the nearest dock and park itself until fully re-charged
* Collects a great deal of cat hair and dust, so it lives up to the pet/allergen claims
* Strong suction. We have an issue of our cat trailing litter everywhere, which we're constantly sweeping. The Roomba is easily able to suck up the litter granules
* Transitions pretty smoothly from the tile to carpet. It only got hung up once, but only because it hit a warped part of the rubber carpet stripping.

CONS:
* Warranty. Comes with one-year limited standard, but with an appliance with this much technology, and at this price point, I would expect at least 5, if not 10, years of coverage.
* Can't use it on furniture, like our couch, which still necessitates owning another vacuum or handheld device
* See above, for carpeted stairs (I mean, you COULD use the Roomba on stairs, but you'd have to manually lift it onto each step, thus defeating the purpose)
* Dust bins are a little small, meaning they need to be changed after every cleaning, but I am willing to concede the overall size of the unit will limit this

If you're on the fence about buying a Roomba, take it from me that it's worth the plunge. I'm now thinking of getting one for my mom and step-dad, who also own a cat, and just don't have much time or energy to vacuum their place. And if you're curious, besides functioning as a high-tech cleaning device, it definitely delivers as an entertaining torture machine for pets.

事实告诉我：我一直认为这个机器人真空吸尘器有点噱头，对于科技爱好者来说可能很好，但是对懒人来说就不是了。所以当它寄到邮箱里的时候，我持着怀疑和不承认的态度来打开箱子，想想，如果不是它的优点的话，那么Roomba将会成为我们的猫Sherlock的一个有趣的很酷的玩具。尽管我很难承认，但现在我确实认为自己当初误会它了。 Roomba 870尽管有一些缺点，但却是一种令人比较意外的机器人，我可能（可能）不会再嫌弃它了。

我的家里：带有一间卧室的公寓，约700平方尺，浴室和厨房有瓷砖，客厅里放有地毯，卧室有衣柜和地毯。一只喜欢到处跑的短毛家猫，我有黑长发的外国妻子也喜欢到处蹦。用了一段时间后，这里是iRobot Roomba 870 的一些优缺点：

优点：

*制造精良。 Roomba像坦克一样，但是边缘很柔和，所以如果它撞到一个物体的话（反正很少发生），不会造成损害

*很安静没有噪音，令人惊讶。在Roomba运行时，我仍然可以听到电视里的立体声对话

*没有太多的旋转刷子，也没有碎片堵塞！你不知道我有多么的高兴（具体来说，它不会被堵在流苏的地毯上走不动！）

*相当直观，简单的设置。我当然不是对技术的无知，但是为了节约时间，我总是喜欢比较简单的编程。可以相对容易地设置多个定期清理 ；

*电池寿命长，可以充电。电池还没有被用完过，因为我没有足够大的空间需要它清理，但这仍然是电量真的很不错了。 Roomba电用完以后会找到最近的地方停下，直到重新充满电

*会扫完大量的猫毛和灰尘，所以对于宠物过敏的人来说，它不会辜负你的期望

*吸力强劲。我们有一个问题，我们的猫把垃圾弄得到处都是，我们正在不断扫除。 Roomba很容易就可以把垃圾扫起来

*从瓷砖到地毯它工作非常顺利。它只出过一次问题，但只是因为它碰到了橡胶地毯脱落了的不平的地方。

缺点：

*保修。只有一年有限的保修期，但是有这个电器，在这个价位上，我觉得尽管没有10年的保修期，也至少需要5年。

*不能在家具上使用，比如我们的沙发，这还需要拥有另一台真空吸尘器或手持设备

*请参阅上文，铺设地毯的楼梯（我的意思是，您可以在楼梯上使用Roomba，但是您必须手动将它放到每一梯，才可以扫干净）

*垃圾箱有点小，这意味着每次清洗后都需要清理，但是我觉得还是被设备的整体尺寸限制了

如果你在购买Roomba的时候，从它可以看出来，这是值得的。我现在正想着为我的妈妈和继父买一个，他们也有一只猫，只是没有太多的时间和精力来打扫他们的房间。如果你比较好奇这个机器人的话，除了是一种高科技的清洁设备，它绝对也是好用的打理宠物的机器。

nd it and bring it back to the dock (think Easter egg hunt).
2. Where it goes it cleans well but it does miss spots that are not blocked. Of course it doesn't get in places in cannot reach but there's places it can reach and doesn't get.

Other than those two points, I like it. We have a golden retriever in the house and the small dirt bin gets full of hair more than anything.

I did not read the instructions and still found it very easy to take apart to remove hair that's plugged around the rollers and other moving points. Very easy to clean, I do this about every 3 uses.

This is an awesome tool really, It's quality built, the battery lasts long but there's still room for improvement. I cannot wait to see how manufacturers improve this tool in the future!

1、对我来说，最烦人的就是它大约一半的时间里都没办法找到充电的地方。它会卡在最奇怪的地方，我会花更多的时间来找到它并把它带回原来的位置（就像复活节彩蛋游戏一样）。

2.它走过的地方被清理得很干净，但是没有被遮挡的地方没有清理干净。当然，它也不能到那些没办法到达的地方，但有些地方它可以清理干净。

除了这两点以后，我都很喜欢。我们家里有一只金毛犬，所以机器人小垃圾桶里的头发比任何东西都多。

我没有阅读说明书，但是仍然发现很容易去除卷在滚筒和其他地方的头发。也很容易清洗，我每用3就清理一次。

这确实是一个很棒的清理器，它质量很好，电池可以使用很长时间，但仍有需要改进的地方。我迫不及待地想知道制造商将来会如何改进这个清理器！
