I've been a Roomba user for almost two years, so I know the benefits of a little automated vacuum. However we had three primary complaints that iRobot has addressed in this new version:

1. Inconvenience of coming home to a dead battery
2. Difficult to clean
3. Noisy
4. Could not focus on dirtier areas; only cleaned randomly.

1. We have gotten into the habit of, as we are walking out the door, putting the Roomba to work. However, we always used to have the problem of coming home to Roomba with a dead battery (inevitably it would die in the worst spots, like under our bed just out of reach). Then we would have to plug him in to our charger (which we had to shell out sixty bucks for) and wait for two hours to use him again. That was complaint one for the old version.

iRobot has fixed the battery issue on the Discovery. The fast charger (which we had to pay for before) is now built in. Secondly, and what has proven to be my favorite new feature of the new Roomba, the little vacuum automatically finds his docking station when his battery is about dead. I do have two recommendations on this note, however. The docking station appears to work just like a virtual wall, Roomba doesn't know that it is there unless it crosses its path, so you make sure that it is in a wide open room where Roomba is sure to cross its path in its waning minutes of power. Secondly, now you have to be extra sure to Roomba-proof the room so that he doesn't get stuck. If he's stuck he won't be able to find his way back to the charger.

2. The new version has gotten much easier to clean, especially the main brush. All the pieces now pop in and out of place easier and there are no screws to remove any of the pieces that need cleaning. This has proven to be a huge benefit.

This was a pretty hard purchase for me. The reasons were 1) It was a pretty expensive item and 2) The reviews for this product were very extreme--from high praise to the pits. (See previous review about the person who returned *four* of them. Hard to believe, actually.) But the promise of an automated robot that would do the daily vacuuming was too much to turn down and I decided to take a chance on the Roomba Discovery. The odds were in my favor as the store I purchased it from offered a 60-day money back guarantee. If it didn't work, no problem.

I unpacked the Roomba Discovery and found these items packed with it: the Roomba, battery pack, charger, two infra-red "wall" devices, a cleaning utility brush, a couple of extra air filters, a wall mount kit, the home charging base, a remote control and associated manuals, advertisements and offers.

The Roomba Discovery and all its contents were fimrly and snuggly packed inside their foam enclosures. After reading the manual, (yes, its a good idea to read the manual), I plugged the Roomba into its home base charger and took it for its first test run around the house the next day. An insert note says that the Roomba needs a 16 hour uninterupted charging cycle the first time around, so if you are in a hurry to clean your house, you'll have to wait at least a day before you can. The Roomba is easy to use and uncomplicated even for a non-techie to use. There are four control buttons on the top of the unit which allows you to turn it on, set it to "clean" mode, another to "max" mode, and one other button to "spot" mode. Each one of these commands tells the Roomba how to clean. Clean is the generic command that allows the robot to freely roam, while the max mode tells the device to clean till it runs out of power.

It's very easy to set up: I just plugged in the battery and the charger, pressed the buttons like the little instruction guide told me, and it hopped on there and started charging.

I let the Roomba wander around for a half hour this morning, and aside from a horrible mishap with my bath mat it did well. Although somewhere inside its little chipular head there is a rhyme and reason to its journey, I could not discern it.

Sometimes it gets stuck, and I just keep an ear out to hear if it needs help. It spent a good two minutes trying to hump a floor lamp, but like an errant cat I swatted at its bumper and it was discouraged.

It's not as loud or as powerful as I thought it might be--it's a different kind of vacuuming. It's basically a sort of robust electric sweeper with a brain. It sometimes has trouble with rug tassels and edges. The acrylic rugs, which are light, peel up off the floor easily and obstruct. The wool rugs are heavier and less trouble.

If you let it wander long enough, it do cover the whole place, though. And that is its big strength.

So does it clean? At first I would have said "so-so," but then I pick it up and go to empty the dirt hopper. Ohmigod. There's cat fur in there from the Jurassic period. I think the big selling point here is coverage--your big human brain is not really built for the mindless repetition of going over and over and over the floor, covering nook and cranny after nook and cranny. Roomba, on the other hand, is completely turned on by the prospect of it. So it gets a lot of the stuff you'd have missed because vacuuming is a mind-numbing chore, and you give it a coupla passes and then say, "Good enough.
