iRobot - Roomba 870 Self-Charging Robot Vacuum - Black/Gray

I must say I really love my iRobot, or Darla, as she's been named. Darla is one lean mean cleaning machine. I was worried about how she would do cleaning hardwoods and going over rugs and then into bedrooms with carpet but she has surpassed all my expectations and has my house looking better than ever. If I had to say a negative thing about her it would be that I wish the battery lasted a little longer (carpet definitely runs it down faster than when it's on the hardwoods), but overall it was well worth the money and it saves me a tremendous amount of time in my cleaning routine.

I was not satisfied with 650 that I bought based on reviews on You Tube. It didn't find it's home often and the filter looks cheap. Finally, it didn't charge itself and became not functioning within 14 days. Since I was not sure if the problems were related to the model or only to mine, I was going to just exchange it with other 650. But there was no inventory of 650 but only 770 and 870. I picked 870 primarily for the design because 770 looks too big and cheap. I am glad that I upgraded it with 870. It has HEPA filter and bigger bin. It's also a little more quiet than 650. In terms of everything, it's worthwhile to pay a little more $$ for long-term use. I also purchased 4-year service plan with which I can replace it with another one in case it's out of order. Less than $20/year, peace of mind for 4 years for a new product from a new company that I don't have an experience with.

Wife purchased the roomba to save us some time in between work, school, gym and our 2 fur babies. She was having to clean up the house and sweep almost every day since our 2 doggies roam the house freely during the day. She's set it to start in the morning before work and while we are walking the doggies in the early eve. We have a 1500 sq/ft house but have closed a could of doors to keep roomba out. We want the doggy room and main part of the house cleaned over everything else. Roomba does a good job. Con: Wished it actually remembered the structure of our rooms instead of being so random The digital walls are nice, but would have liked them to be batter savers and able to leave them on. We have to turn them off and on when roomba is starting.

Like most I thought there was no way these things could possibly do all that they claim. Well I was wrong! They really work great and can navigate all over the place very well. They surprisingly pick up copious amounts of dirt and pet fur. I'm stunned every time I empty the canister and see how much stuff it cleaned. Most of the reviews are very similar to mine. One of the best purchases I have made. Don't be shy and buy one of the lower priced models. Get the better one with the brushless system. Waking up everyday with a perfectly cleaned house is amazing!

I am a late adopter with robot vacuums primarily because I had performance concerns and did not want to pay hundreds of dollars for a large paperweight. However, I have been delighted by the performance of my Roomba 870. It has been in service for several weeks now with no performance issues and so far has proven to be an incredible time saver for me in maintaining our 2000SF office. Basic usage is intuitive enough that I was able to charge it straight out of the box and to use it immediately after charging without even consulting the product guide. In fact, due to time constraints, I still have not set up my barriers and have not programmed the unit for unattended use--I just hit the 'start' button and let the Roomba run in the background while I am doing other cleaning chores in the office. I especially appreciate that it is easy on furniture legs--which I understand is not true of all types of robot vacuums, or all models. The suction is amazing -- so far, I have not found a single spec of soil it has missed. While our floors are all sealed concrete I think in some ways this makes them harder to vacuum, as the dust tends to fly around when I am running a traditional vacuum or even vacuuming with a wand. The Roomba, thanks to its perseverance, seems to be able to eventually capture all of it. My only regret is that I did not purchase one of these sooner!

I had high expectation for this device since Consumer Reports gave it the highest score of all the robots they reviewed. This 870 Roomba picks up things well on carpet and hardfloor but I can still find things to manually pickup after. Nothing beats a human eye! The algorithm to clean can be improved. The robot went over the same old spots while there were other areas in the house it had not gone to.

I bought the Roomba 870 after my daughter and her husband bought one and recommended it. My wife and I love it but I do have some qualifications. First, for most people it probably won't replace your vacuum cleaner totally. However, it is a great addition and significantly reduces the need for a normal vacuum cleaner or Swiffering. On our main floor we have about 1200 square feet of wood floors with area rugs in several areas. We also have two large dogs who are moderate hair shedders. As a result, when I run the Roomba, the dirt compartment will need to be dumped at the end of each run. If I haven't run the Roomba for a few days, I may need to dump the dirt compartment half way through a run. I also have found the need to clean the filter regularly and also the rollers underneath the unit at least once per week. Still, I would rather do that than manually Swiffer or vacuum the floor myself every few days. However, if you aren't willing to do this periodic maintenance you may want to steer clear of this device, particularly if you have shedding animals in the house. I rated this 4 stars because of the need for regular maintenance but I really do love this machine. It is well designed and a lot of thought was put in to the design to make it easy to do the periodic maintenance easily. I would buy this again without reservation. By the way, even my regular vacuum cleaner needs periodic cleaning to get the dog hairs out of the beater brush and to clean the vacuum filter so no cleaning device is maintenance free.

We upgraded from a 500 series to this 800 series model and what a difference! We have 4 house cats and this one picks up cat fur so much better than the old one it's unbelievable. It also has a much larger hopper to hold more dirt than the lesser models. The mechanism on this one stays much cleaner with the rubber rollers rather than the brushes so there is less manual cleaning required. That's not to say you can forget about it but is a lot easier and quicker to do. It still presents a problem with oriental rug fringe because of the swirling brush, so we just place a virtual wall along the fringe and it stays away from it. This does not replace a standard vacuum. you still need one to do touch ups and hard to reach areas, but it makes the task a lot less cumbersome. Overall we are very pleased with this purchase.
