Summary: This is my second Roomba. The other one lasted a long time, but eventually died. This goes under beds and furniture where dust bunnies hide. It sucks up a lot of dirt and is a huge time saver. I vacuum much more frequently with this since and just move it around the house.
Summary: The 880 is so much better than this one. I have both, and I wish I could trade in the 770. What's wrong with this one? First, hair (pet and human) wraps around the ends of the rollers and is difficult to get off. Second, it picks up much less.
Summary: This is one powerful little machine! Super easy to set up and use. It vacuumed my living room, dining room, office, bathroom, hallway, master bedroom and guest bedroom without needed to recharge.
Summary: The vacuum cleans good but through the places it goes only. The streaks where it didn't clean can definitely be seen... I have a area between the stove and the kitchen island, where we cook, that it gets particularly dirty.
Summary: We recently had all new hardwood installed on the ground floor of our home, about 1600 sq ft. It's a darker color that shows everything. We love the floors but my wife complained about having to vacuum every day. So........I bought her this Roomba for Christmas.
Summary: We've lived with our pet Roomba now for about a month. Here is the good and the bad. First off the bad, that way you'll remember the good. We have some bar stools that are 18 X 18, so a little larger than standard. They are the exact, perfect size for poor Roomba to get stuck.
