The little Robot that cleans BIG
By Cricket
Watch Video Here: http://www.amazon.com/review/R2DFXD89QIRDI8 Even with numerous friends that swear by their Roomba, I was still skeptical. How could this little machine really clean enough to impress me?

When I received it I was really surprised at the size of it, much smaller than I had imagined. I was anxious to test it out, so using the quick start guide I had it unpacked and on the charger in less than 10 minutes. I do suggest that you consider the location you want to set up the home base, not because it'll take up much room, more just to have it out of the way if possible; mine is under an end table.

I decided to start it on a Monday through Friday schedule at 3:15pm each day. It's a time when the house is usually empty and it would be less of a bother. The first time it ran of course I was home and I think I watched it the entire cleaning cycle. I was amused to say the least and it also let me see what problems might arise. I realized I needed to install a virtual wall to keep it from the laundry room as this is also our cats room for food, water and litter box. I also took notice of cords and other items that were loose or in the way and that needed to be picked up or secured. During this first cleaning the "full bin" light did come on, which definitely showed me that it was picking up plenty. After about 2 hours it did head back home to its dock for a recharge and had no trouble finding it.

The course the Roomba takes is still a mystery to me. Mine goes from one room to the next and back and forth several times. Sometimes it zigzags and other times it follows a path. Overall though the carpets and hardwood floors are noticeably cleaner. I still run my regular vacuum once on the weekend, but the amount it picks up is a lot less than it used to average and I can see it through the clear canister.

Maintenance is pretty easy on th e iRobot Roomba 770 Vacuum Cleaning Robot. It comes with an extra set of HEPA filters and some cleaning tools. The round brush cleaner is especially helpful in our household, because both my daughter and I have long hair that loves to get sucked up and caught in the vacuum brush. Otherwise emptying the dust bin is very simple and mess free.

If I had to bring up any negatives about Roomba 770 it would be these two minor issues:
* Find a way to not have to use C batteries for the virtual walls. With so many power/battery options available and especially on such a high end appliance, this just seemed out of place and inconvenient.
* Provide a hard copy manual. I appreciate the CD, but the first time a light came on that I didn't know it was a hassle to have to boot up my computer just to look at the manual. (I've now printed it out for myself.)

My final opinion on the Roomba is that it definitely exceeded my expectations on its cleaning ability . It's intuitiveness, style and ease of use also impressed me and the four stars that I've giving it are well earned! Hopefully I've covered most all of it's features, but if there is something I've missed or a question you have feel free to leave me a comment and I promised to respond.

*Update 9/9/12 - Now that the Roomba has been cleaning for 3 months I wanted to comment further on how it's doing. At first I was still vacuuming once a week, but now I don't find the need to do that at all because what it was picking up was so minor it was a waste of my time. I've also found that it has more of a set pattern. It still zig zags occasionally, but it's more consistent now. Overall it's nice coming home from work everyday seeing a vacuumed floor and knowing that I didn't have to do it!

Life changing product!
By Sammy
I am 41 years old and have had allergies my entire life - they have gotten worse over the past 5 years. I already take Singulair and Claritin but still have symptoms. I was just diagnosed with asthma, which apparently was caused by my allergies. Thus, I decided to wage war on indoor allergies in my house.

I hired a cleaning company to clean my house a few years ago - they were horrible. I did a better job then they did. Also, I have pets and am not comfortable with someone being in my house with them when I am not there. My problem is time - I work full time and was finding little time to vacuum (to the point where I was vacuuming only once every week or other week). I have 3 cats and one dog, with hardwood floors and area rugs on my first floor and carpet in my bedroom and hallway upstairs. My house was not clean, to say the least. I just couldn't keep up with it.

My brother suggested that I purchase this product. I thought, why not? I did not buy this on Amazon because they did not offer the 770 model at the time of my purchase (in April 2012) or I would have - I bought it from the iRobot website.

This model offers a vacuum with HEPA filters in the dust cartridge. Please note that the low cost models like the Mint are not vacuums! They just push around a dusting cloth to collect dust. This would not meet my requirements, for obvious reasons. This product also has a schedule so I can tell it to start vacuuming at a certain time each day. You can also start the cleaning manually at any time but pushing a button.

It's not loud - much quieter than a regular vacuum and I can be watching TV in this room and it's vacuuming in the next room - would be too loud to watch TV if it were running in the same room. And, my cats and my dog were not afraid of it at all. They can be in the same room with it with no issues. It moves slowly so it it is coming towards them, they just move out of the way.

It comes with an instructional DVD which you don't really need as it's pretty easy to figure out. It runs for up to 3 hours on a charge, and will take itself back to its docking station if it needs to recharge and when it's done cleaning. It has cliff sensors so it knows it it is near steps, for example, and will not fall down! It also has a dirt sensor and will go over an area repeatedly if it finds a lot of dirt until it's clean.

The dust bin is a good size - I have yet to fill it up to the point where the vacuum can't go on until I empty it (it has a dust bin light which turns on to tell you if it's full). But, this is not meant to catch the same amount of dirt as you would have if you vacuumed every week or two - this is intended to be used for regular maintenance (every day or two) so it doesn't need to have the same size dust bin as a regular vacuum.

I have a Dyson Canister vac and this product works better than that for many reasons. First, it takes the time to clean the floors - as long as it needs and will go over an area until it's clean. Also, it has an edge cleaning tool built in and cleans along edges (for example, against the wall) well. I have a 2600 square foot house and I couldn't even clean one floor in 8 hours before, since I was rushing to vacuum, dust, etc. in the one day that I had on the weekend to clean.

Since purchasing this product, my asthma has improved significantly and my house is spotless! I loved it so much that I bought another one for the second floor. And, I have found that I dust much less - I used to have to dust every few days (and didn't, ended up doing this once a week if I found the time) and now, I dust every 3 weeks!

This is a life changing product for me. Yes, it's expensive but it costs about the same as my Dyson and it does all of the work for me. I highly recommend this product!

I LOVE THIS THING.
By Nettabird
This is awesome! I hit the button when my toddler (who is afraid of it, but she'll get used to it) and I leave the apartment and when we come back there are fresh vacuum lines all over the carpets! Helps me keep clutter off the floor, too, since I know it's going to hit everywhere. Now I'm looking at a scooba too. Soon as I have more than 20 square feet of linoleum...

Here's how it decides which way to go, since I know a lot of people are confused: it's random, which *is* the most efficient method for a computer to figure out how to cover an entire floor, according to my husband who works in computer science. It's an easy enough problem in computer science to make an algorithm for figuring out how to determine if an obstacle is a wall or a chair leg, so it does that too. You might think it would be more efficient to map out the room and then just go back and forth, but it's actually really difficult to develop the step-by-step method that a computer needs in or der to figure that out. Plus, you'd have to leave everything in exactly the same place.

I've seen complaints on some Roomba reviews about how you have to clean the brushes and filter every week, and how often you have to empty the bin. I don't get it. This thing VACUUMS YOUR FLOORS FOR YOU. You have to do the same maintenance on a vacuum that requires you to push it across the floor. Such a shame that the makers of this ROBOT IN YOUR HOME are still bound by the laws of physics and current computer technology...
