iRobot Roomba 4210 Discovery Vacuuming Robot

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.

3. The Discovery is noticeably quieter than the older versions, especially on tile surfaces.

4. The new line of Roomba Floorvacs comes with sensors that can detect dirt. That was the first thing we tested when we got our Discovery. I had pieces of Styrofoam broken into small pieces and it detected it and automatically performed a spot clean on that area. Then I put him in the kitchen where I had accidentally dumped a bag of cereal on the floor and then managed to step on it...Roomba focused on that area and cleaned up every little crumb.

I love my Roomba. I 100% recommend that you get one. I bought mine at a local store in the mall and had to return my Pro Elite version 4 times before I finally got one that wasn't buggy. Then, under the warrantee, after my fourth one went on the fritz I was able to upgrade to the Discovery for free. So far after 2 weeks, the Discovery has been bug-free.

Nevertheless, because of the many issues that I have had in the past, and as with any new and emerging technology, buy it where you can purchase an extended warrantee and easily return defective devices.

Notwithstanding, buy a Roomba. Even though my wife and I never have time to clean our floors have been spotless for the last two years.

I hope this helps.
