I’ve read horror stories about pet owners having problems with their Roombas and even scoffed at a few. As mine is a much older unit -- a 530 -- I never thought much about it. So it was with this false sense of security that I pressed the button and let the Roomba, nicknamed ‘Gru’ do its thing over the hardwoods recently.I settled back in my office chair at the desk as I do everyday, noise canceling headphones on, typing away on the computer -- working on another chapter of my next novel. Somewhere between pages four and six, I heard this ungodly howl.At that point I remembered Stanley was in the house. He’s my neighbor’s creme colored Chihuahua. The neighbor had a doctor’s appointment and asked me to dog-sit. Stanley had gotten sick earlier and she didn’t want to leave him all alone.Stanley first met Gru last year when he was just a puppy during a visit by said neighbor. At that time he’d clearly mistook Gru for a large, flat, white toy and tried to play with it. Gru was doing its thing and backed up, whirled around and went off in another direction, our cat was draped indolently astride it smirking at the barking pup.Any one who owns a Roomba knows that they work by mapping the room. Having already mapped that one, Gru charged full steam ahead and only slowed down after bumping into Stanley. The pup was surprised but unhurt. Ever since then he’s kept his distance from Gru.When I got to the living room something smacked me squarely on the right cheek. It’s wet, has the consistency of dark cottage cheese and smells like something that Stanley’s bowels couldn’t hold in. It’s retched. There’s a slick stain of runny poo and what looks like vomit on the middle of the floor. I’d been warned about the possibility of poo -- not puke.Gru has evidently detected it. The “dirt” sensor is lit. The spinning brush on the right corner is whirling faster than Thor’s hammer in a fight-- with much more destructive impact.The poo-vomit mixture is airborne and taking indiscriminate aim at the white walls, the tan couch, my favorite wing-back chair and the center rug.As the Roomba backs up and in doing so flings more of the hellish puke back at Stanley who howls in protest. I can see why he’s so upset. One eye is coated with it as are his legs and tail. The poor dog’s fur is longer creme colored.Gru spins and Stanley jumps for safety, landing on the couch, immediately rubbing his head against the seat cushion obviously trying to reclaim the sight in his beady little eye.I rush forward to stop Gru as it heads under the side table. The spinning brush is fully loaded again so its merrily catapulting poo-vomit against the side of the couch and the wall. The cat must have sought refuge under there cause she comes dashing out like she’s sprouted wings and leaps on the table and then the arm of the couch where she proceeds to vomit on the other cushion.Part of my frazzled mind registers that she’s the source of the puke as I dash after Gru who by now is under the couch. Not that I can blame her, I’m close to doing the same thing.I get down on my knees and am just about to look under the couch when I feel the wet spray of another coating of poo-vomit hit the side of my legs. At this point I know one of two things will happen if I put my face down there to eyeball where Gru is and don’t like either option.I can hear it humming along and traveling toward the other end, so I get back on my feet and head down there to ambush it.Stanley has managed to clear his eye. I haven’t the heart to look at the couch cushions right now, I know it’s bad. He’s found his courage and jumps on the arm near me barking like a fiend.As Gru comes chugging along I think Stanley’s courage has abandoned him. He leaps off the couch with a frightened yelp, forcing me to step around as he darts out of the way, I’m in socks and the floor is slick, so I slip, falling hard on one knee.Gru has headed back to the slick spot on the floor. “Dirt” light still a glow.Getting back up, I’m now running after the Roomba and hit the green button just as its brushes are reloading. I haven’t had time to do more than make a cursory look at the damage. It’s bad.Now that Gru is still. Stanley comes back out-- barking like a fiend. The cat’s mewling -- either egged on by the Chihuahua or just by pure feline indignation. She jumps on the filthy vacuum and of course lands on the green button-- turning Gru back on. The spinning brush takes aim as it backs up shooting more crap all over me.I dive for the button but the floor is even slicker here and I hear a snapping sound as I fall on my ankle. The pain is excruciating. All I can do is lay there in poo and vomit for a moment, calling the Roomba several unmentionable names -- none of which is Gru.Whirling again Gru heads off down the hall slinging the vile mixture on both walls. All I can think is its going to my office! And I half crawl half drag myself after it. Luckily the pattern for the hallway requires that Roomba make long passes down the hall and back before it leaves it. I caught it when it reversed direction, turned it off and more importantly turned it upside down.Ignoring the cat-dog protests still going strong in the living room, I get my phone and call my boyfriend and tell him about the accident.I drag myself to the bathroom and onto the tub where I proceed to clean myself up and examine how bad the ankle is. It’s swelling and turning colors.Sam comes home about twenty minutes later. All I hear is the door opening and his stunned voice saying, “Oh hell! Man, how’d it get on the flat-screen? Oh God, this is awful.”Surprisingly he doesn’t call out to me but I hear his footsteps before he shows up at the bathroom door several seconds later looking distinctly green.“You okay?” I ask.He looks vaguely uncertain. “It’s everywhere,” he says in disbelief.After getting me some clean clothes he helps me out to the car and goes back in the house for a moment. Later telling me that he put Stanley in one bathroom and the cat in the other.While I have my foot x-rayed, he’s on the phone with one of those restoration cleaning services. My foot isn’t broken just badly sprained. Unfortunately the cleaning folks can’t come out that afternoon.I’m laid up, so when we get home --the job, despicable as it is, is on him. My neighbor comes over to retrieve Stanley and offers to take the cat home with her-- vowing to bathe them both while Sam is trying to salvage what he can from the living room.Soon the smell of bleach is strong and thanks to prescription pain pills I’m off to the land of fitful dreams.The TV survived as did the side table and my Wingback chair. The couch and the rug from my mom went to the furniture graveyard.Sam never did clean the Roomba, he put it in a bag on the back porch. I’m the more mechanical one, so I did my best to dismantle it and clean the components which required donning long sleeved rubber gloves, a face mask and taking it apart. I didn’t take the motherboard out but I did use two cans of compressed air. (Hence the mask).The battery wouldn’t recharge after I put it back together and I thought that it was a goner. I bought a replacement one from here and I popped it in right out of the shipping box (it arrived fully charged) and Gru came back to life. It’s been running like clockwork ever since.

For the first time, basically ever, my 960 went around the entire house and didn't die in some random corner. The original 1800mAh batteries are really not adequate, and Roomba will charge you 4x the price of this one for 3300mAh, which is probably enough, but why pay that much? Even if it lasts just one year it is cheaper than the manufacturer part. As usual iRobot has priced themselves out of the business.Just adding a small update which might be useful to people. My 960, and I would suspect other Roombas, is EXTREMELY easy to confuse and hard to convince to charge a new battery correctly. This battery seems to work great, but I had to reset my vaccum several times, and finally reset, and then immediately remove the new battery, wait a couple minutes, and put it back. Until I did that I got weird battery charging errors and the vacuum would only charge itself about 10%!!! This was not the battery's fault, and just a simple 'reset roomba' from the app wasn't enough to fix it. Now it works great however. So, you may want to fiddle, and fiddle more than you imagine you need to, before your roomba is 'happy' with its new battery.

I get a charging error periodically, but it's not a big deal. When I first got the battery and charged it and ran it down all the way, it ran for 3 hours! Amazing! But of course, when it runs all the way down, I always get a charging error. I just pick up the Roomba, and place it in the dock to resolve the error. Buy when the error happens, it blinks the error code but doesn't seem to charge, so you have to deal with it.

Not the length of time I was hoping to get out of this.

The battery worked for about a month then it started having issues. It started running out quickly and wouldn’t charge. I’d have to take the battery out and replace it for it to be able to charge. That worked for a few months but was irritating that I’d had to reset it every 2-3 cleanings. Now it won’t charge at all. It’s completely dead. So it worked fine at first then started having issues after about a month (past the return date), now won’t charge after 7 months.

I got my Roomba 550 (lists 551 on the bottom of the machine though) from Costco about 4 years ago. Clean button started flashing red light and stopped working. I tried charging it for days, resetting, taking out battery and cleaning the contact points. Nothing worked. Contacted iRobot. Rep said it due for a new battery after testing several things. She sent me the links but both options are expensive. Came to Amazon for cheaper options. I initially went for Tengery which has tons of good reviews, but still got flashing red light. Contacted Tengery, tried different things (service is good), still no luck. Got my refund. Spent hours on internet again, spotted a keyword "NiCd 3000 mAh" (have no idea what exactly that means;)), and it brought me to Housmile. The reviews were good but not whole a lot. Hesitant a bit but with the price and warranty, nothing to lose. And....it works! No flashing red lights. My iRobot is alive again. I scheduled it to run 4 days a week. It passed first week test. So far so good. Will report again when it dies.========================update========================I thought I found a solution. Unfortunately, the dead red ring started 2 days ago. tried to charge it overnight and still got red flash. Went through the standard steps: cleaned brush, took out battery and reset. No luck. Gladly, it's still within 30 day warranty. Perhaps I should just give up on my irobot.
