Please click on a question to see its answers.

A:yes...we have a strip that goes from wood to tile (tile was put in before) that is a good 1/2 to 1 inch step & it just does fine. Roombas are nice to set & let it do it's thing (especially for under beds) but I do still like getting a reg. vacuum out once in awhile.

A:Our Roomba will go right over things like cords. The problem is, she's really good at vacuuming so sometimes the cords either get caught and she stops, or she yanks on them and pulls lamps and telephones off tables. So we've done two things to combat: 1) we got some 3M strips for cords and hung them up so they're out o… see more Our Roomba will go right over things like cords. The problem is, she's really good at vacuuming so sometimes the cords either get caught and she stops, or she yanks on them and pulls lamps and telephones off tables. So we've done two things to combat: 1) we got some 3M strips for cords and hung them up so they're out of her way and 2) we've used the lighthouses/haloes so she avoids areas like under the computer desk where there are a lot of cords. It's much more worth it to have a Roomba and spend an hour Roomba-proofing the house than it is to vacuum. see less

A:Yes. It does a good job with hard wood floors. We have a golden retriever that sheds a lot and its nice to not see clumps of hair on our hard wood floors.

A:I think so! We have hardwood with some area rugs and it's been our sole vacuum for just about a month. We'll likely need to pull out the Electrolux just to vacuum off the bricks on our woodstove hearth, but I really can't fault the Roomba for not getting in the deep mortar joints on our brick work.

We'll likely need to pull out the Electrolux just to vacuum off the bricks on our woodstove hearth, but I really can't fault the Roomba for not getting in the deep mortar joints on our brick work. We were thinking about picking up a small handheld vac (like the Shark 12 volt) to make such brick work and stairs a breeze. see less

A:The storage compartment holds quite a lot. I turn my Roomba on and let it clean the whole house. It docks itself and a light will come on when the compartment is full and needs to be emptied.

I turn my Roomba on and let it clean the whole house. It docks itself and a light will come on when the compartment is full and needs to be emptied. However, I usually empty mine after each cleaning. It's amazing how much it picks up, and emptying the compartment of debris is a breeze. VERY simple and easy. Pull out the tray from the front, empty it and slide it back in until it snaps. When in place, it looks like part of the machine. I love mine...... !!! So glad I got it. Saves me a lot of work. see less

A:Noisy if it's on hardwood. We have it turn on when we're at work so it's not an issue.

A:Angles aren't a problem at all because the Roomba can follow walls and the edges of furniture. While it does have some degree of logic, it pretty much just bounces off every surface in every direction until it gets the job done.

While it does have some degree of logic, it pretty much just bounces off every surface in every direction until it gets the job done. I have a small apartment with too much furniture and it rarely has issues. Once in a while, I'll find it stranded and out of charge at the far end of the apartment but that's most likely because I don't have a lighthouse for it to find its way home reliably. Aside from that, I'd say it works well in any space as long as there aren't things on the floor that can get wrapped around the rollers. It is one of the best purchases I have ever made and I will absolutely buy another one when Roombie croaks. see less

A:Yes, when comparing to a regular vacuum. But no, it's annoying if you are staying in the same room with it. It makes mechanical noises and bumps around. I ususally close the door, or go to a different room or floor when it is doing its job. You can also just turn it on when you are going out.

A:It performs similar to how a broom and dustpan would work on a carpet.

A:It's got this little brush that extends out from it that rotates and sweeps corners. Trust me I was skeptical at first but it does a great job.

A:Roomba will clean your whole house, or as much as it can do on one charge. A charge last about 2 hours, so Roomba can do my whole (one story 3 bedroom) home on one charge. You can also set it to spot clean a certain area when needed. As long as there are no stairs in between, Roomba moves itself from room to room.

A:I'm new to roomba but my daughter has had one for years, and has never had to replace the battery.

A:You can program it which way you want. For example monday 2 pm tuesday 5 pm not on wednesday etc. :)

A:Mine picks up everything, no matter what! Our cat loves playing with those rubber bands that are covered and are for pony tails. She leaves them all over the house and I have to continually take them out of my Roomba. So, if it picks up those, and it picks up the long white cat hair, yep, it will pick up those leaves.

A:While we have a non shedding dog that has not been the case for us. I have cleaned out the filters once (banging out the dust) other than that nothing really over the last 5 months. Hope this helps.

A:No, but I'm finding that it gets filled up pretty quickly picking up after our shepherd mix. We ask a lot of our 770 and, while there's room for improvement, it's still been well worth the money after having it for six months.

A:It docks, but does not finish the job after charging. You have to relaunch it. Most of the time it needs to be emptied anyway at that point

A:Hello,So far, i have no issues with the "Soft Touch" feature. Around the Robot is rubber so that protects your funiture.

A:I have 2 rugs with fringes and there has not been a problem

A:it will pick them up but usually has to go over them a few times. I find it does better on larger things as opposed to threads and things like that.

A:Answer this question

A:It picks up dry kitty litter fine. If it's wet, things could get messy.

A:We have had no problems with hair. Once or twice we have got it caught called up in an iPhone cord or something of that nature. Hair has never been a problem although we deal more with pet hair than human hair. We have found this unit to be performing very well.

A:Yes, about 8 out of 10 times. Usually gets stuck in closet when the door closes on itself.

A:According to iRobot website change filters every 2 months "regular" use but I dont see a definition of " regular".

A:How often will depend a lot on your floors. If it's wood floor or tiles, a lot less, carpeting or rugs, a lot more. I have a 50-50 combination in my house.I have not changed the brushes since I have had my 770 (13 months now). I use it once a week to do 5 or 6 rooms (2 charges).

I have a 50-50 combination in my house.I have not changed the brushes since I have had my 770 (13 months now). I use it once a week to do 5 or 6 rooms (2 charges). I end up cleaning the brushes once a month or sooner if I see they are really clogged with hair, using the plastic tools provided, mostly the flat one rather than the round one. It's a bit time consuming if you do it right, but I consider it part of the routine maintenance.Regarding the filters, I have not even used the replacement set of filters that came with the robot yet. So far I simply clean the filters under running water for 10-15sec and let them dry overnight. I do it every couple of months.When I clean the filters, I also clean the dustbin under running water. You could simply wipe it with a wet rag if you are not comfortable with running water. Make sure to shake it and let it dry before putting it back. see less

There is no 660 listed (old model?) but my 770 has both optical and acoustic sensors for debris while the 650 is just acoustic. The 770 has HEPA filtration while the 650 does not and the 770 has the AeroVac Series 2 dust bin: "Standard Bin vacuums dirt, dust and crumbs off your floor. AeroVac™ Series 2 Bin holds more debris than Standard and vigorously pulls debris and hair off brushes into the bin." I diddled for quite a while before pulling the trigger on the 770, but I'm happy with my purchase. see less

A:As with any other item, I'm sure that the length it will last will depend on how well you maintain it and clean it. I have had mine three or four years and it is still working great. There is a light that will come on to let you know the dust bin is full and needs to be emptied. You should empty it promptly.

I have had mine three or four years and it is still working great. There is a light that will come on to let you know the dust bin is full and needs to be emptied. You should empty it promptly. I clean out the bin each time I run my vacuum whether the light is on or not. I have taken it completely apart and cleaned it thoroughly only twice. Carpet threads or animal hair can get wound around the roller and you have to remove it in order for the unit to do its job. Mine started making a funny noise and when I checked I found that the roller needed to be cleaned. When I got everything unwound from the roller, it was fine again. I think if maintained properly, it should last quite a long time. I would not want to be without mine ... I love it. see less

A:Your dog will get used to it. My cat was cautious at first, but too curious to run away. Now he watches it and only moves when it heads for him. How about distracting your dog with a few treats when the Roomba first starts up? That might be an effective distraction.

A:My dog is a shepherd/lab mix. We live in Texas, and I run him 5 miles a day.He sheds a bunch! He doesn't have tufts, but I could not live without it.Hope that helps.

A:It said not to get it wet on the instructions, and it has knocked over dog bowl and been ok. But it doesn't pick it up.

A:Answer this question

A:We have carpet, hardwood, also porcelain tile. So far we have clean floors everywhere. We are very pleased with our roomba. Good luck!

A:The 770 has a hepa filter and has dirt detect that has it work a spot until clean

A:Yes! I have 2 australian shepherds that shed constantly. This does a great job of picking up pet hair! The rollers are also easily removed and it comes with cleaning tools to remove the pet fur from the rollers!

A:Hi, Sherry. By my estimation, 2-1/2". Yeah, it can hunker under lots of stuff. Update: I just re-measured and still come up with 2-1/2"--I measured the side from the floor to the top of the side.

A:Great question. We have 3500sq. ft. with both hardwood and area rugs with fringe, along with wall to wall carpet. This Roomba cleans all very nicely. No problems at this house.

A:only if they are actually touching the floor

A:It will avoid tangling with electric cords most of the time. If it does however, it will go into "anti tangling" mode and reverse brushes. I have seen that already. If unable to untangle it will stop and turn itself off, then wait for you to come home to the rescue. The more wires you remove from the vacuum area the better.

A:They are completely portable and easy to move around.

A:Haven't had to replace any yet. Love our Roomba!

A:Usually when my Roomba does this, I have to stop it and turn it over and clean it. This usually helps out a lot. I have pets and the cat fur seems to clog it up and it goes round and round. Check underneath the bottom and see if that will help.

A:From what I gather from the iRobot website and other things I've read, it does not (which explains why it will bump into an object more than once). iRobot states that it uses an algorithm to perform the function.

There are other robo-vacs out there that do "map" the area but they are much more expensive due to storage of the data and the sensors needed to do it correctly. Also, it would make it difficult if you had more than one area that you ran the robo-vac in as it has no way of knowing what area it is in so it would probably have to re-map the area each time. see less

A:If it is done cleaning, it says "move to a new location" and shuts down. If it needs charging, it tells you to dock it and the battery shape on top turns red. When battery is completely charged, it turns green.

A:Probably will. We try to keep cords etc away He will get stuck and tangled on lots of things . We arranged things to suit his abilities . Still one of the best things I bought

A:It runs in a totally random pattern. it does not seem to matter much where the charger is located, but it seems to spend a little more time closer to it. It finds the back corners of the closets, under beds and most everywhere in our home. It does not always seem to concentrate on the same areas each day.

After a month or more we really like it. see less

A:We do not have a shag rug in the house, but one of the bedrooms has pretty thick pile carpeting. Absolutely no problem there. I am not aware that you can make Roomba avoid a particular rug.

I am not aware that you can make Roomba avoid a particular rug. Besides, a shag rug is more apt to collect dust due to the thickness of the pile. So you actually would want to have Roomba clean it even more. Don't worry if the dust bin fills up with just once cleaning, or even before the cleaning cycle is over (the red ! will light up), that's what it is for.About clogging, Roomba won't clog per se but you do need to clean the rolling brushes once in a while to remove hairs and whatnot from the brushes. There is a tool provided to help do that. Hope this answers your questions. see less

A:I have a rug with 3 inch fringe. Once in a while, Roomba drags the corner of the rug for a few seconds, but it never gets stuck, and doesn't damage the rug.

At any rate, it's fine on my 3 inch fringe. see less

A:Hold down CLEAN button for 10 seconds.

A:I bought mine in Nov. of 2013 and it is still under warranty. 1 year limited warranty.

A:1. Their is no bag. I empty the container after 1 or2 runs. My wife has a 18 lb wire haired terrier that is very prolific at shedding.

A:Ours does a very good job on both carpet and tile. I don't know if it gets 100% but it is very good.

A:Ohio

A:Answer this question

A:Are you talking about some sort of magnetic strip on the floor? There is nothing in the manual about it sensing that. The 770 has acoustic and IR sensors. Nothing relating to magnetic sensors.

A:you can use the remote to return it to the base at any time.

A:Answer this question

A:one year

A:Yes mine included two towers to create one wall, a remote control, and charging base.

A:Answer this question

A:I have no idea .... wish I could help you. You might go to the iRobot Roomba website and research. I looked briefly, and there were manuals in other languages, so I'm thinking it is a possibility. Hope you find your answer.

A:I have to use it to guide Rosie to another room, but it's not easy to steer her. So I just pick her up. Don't let that affect your decision to buy. We really like ours. It does a great job. If have anymore questions get back to me.

A:I would say yes. probably have to empty basket and check to make sure it does not get hung up. I doubt it would get it all done unattended

A:Answer this question

A:We did have this happen. It did not ruin the Roomba as it is easy to clean. If you had one of the first ones that came out, this one is greatly improved. It is absolutely amazing.

I have 2 dogs and 5 kids. It has kept up with the dog hair, crumbs, and much more. It actually picked up our daughters sock (I missed it when picking up after her) and it stopped, turned itself off and I easily took it out when we got home. I love that "Roberta" (yes, we named her) can turn herself on and recharge herself. I have to remember to empty her - which is daily in my house. My floors have never stayed cleaner and I have a maid! She is as grateful for her as I am. BEST INVESTMENT! I can wait to try the mop version! see less

A:Can't answer specifically for that type of flooring but I assume fine. I have it do my basement which is carpet and travertine tile. It does fine.

A:Yup. Like a charm.

A:Answer this question

A:Its the docking button. It tells the roomba to stop cleaning and go dock itself.

A:I have dogs thus I empty the bin every time after use. If your room is not very dusty, may be after several use ok. They will be a red light if bin is full.

A:110

A:Yep. Mine hasn't had any issues. The only problems it would have is with shaggy rugs (which I don't have). Other than that the transition is seamless.

A:I haven't tried it but it works wonderfully on hard surfaces like wood floors and tile

A:Oh, yes. It travels well. The problem is that it leaves the edge of the floor dirty along the carpet edge. Not happy with mine.

A:Answer this question

A:I have dark hardwood floors as well. I have not had this problem. However consider cleaning the rollers and wheels. There maybe something on them causing the marks.
