i-Robot Roomba 770 Vacuum Cleaner

Product information

Sit back and let the iRobot Roomba 770 vacuum cleaning robot do the hard work!

This machine vacuums on its own using iAdapt™ Responsive Cleaning Technology, and is a multi-floor cleaner, handling carpet, hardwood, tile and linoleum with ease. It cleans on a schedule that is convenient for you, and stays in the rooms you want to clean and out of the ones you don’t. And with a convenient carrying handle, transporting the Roomba between floors is a breeze.

Advanced features include:

  • Dust bin full indicator: helpfully lets you know when the dust bin is full
  • Sensory cleaning for excellent results: the 770 uses optical and acoustic sensors to detect large and small particles. It also employs a brush-like, back and forth motion in areas where it senses excessive dirt to focus cleaning effort
  • Advanced cleaning head: this provides superior performance for picking up dirt, dust, pet hair, allergens and more from carpets and hard floors
  • AeroVac™ Series 2 bin: vigorously pulls debris and hair of brushes into the bin, which holds even more debris than previous machines
  • Dual HEPA filters: these capture dust particles as fine as 0.3 microns, leaving fresher and healthier air behind
  • Soft-touch bumper: the moulded bumper cushions the contact made between the surface of Roomba and walls, furniture and other objects in the room

Q & As


i-Robot Roomba 770 Vacuum Cleaner 4.8 5 28 28
Love it! I bought the Roomba because with two dogs and two children, unless I vacuumed every night the house would never feel clean. It was a great decision! The dog hair is picked up easily and overall dust levels have dropped. I run a scheduled clean each day while I'm at work then in the evenings have it clean an upstairs room depending on where needs doing next. I'd definitely recommend it! I was a bit nervous about reviews I had read on the internet which suggested that the Roomba can die after 12 months - but that's where the John .lewis 2 year guarantee will come into play if I need it! 19 August 2014
Excellent investment and really works. I love letting it do its work whilst I do other things. All you have to do is empty its bin and occasionally change the little filters which is very easy. Common sense says don't leave wires or small items on the floor. I have 2 dogs and 2 cats and it picks up the hairs very well and brushes up the carpets to look like new. 07 June 2014
Believe the hype! Had hesitated for a while due to price, but always suspected this was the product for me. How right I was. We live in a flat so its territory is wide lateral space, all on one level, with just a small staircase up from the front door to the central landing. All our floors are either hardwood or stone tiled with nowhere for dust, grit or hair to hide, and our little robot patrols constantly ensuring they are kept clean. It starts where you tell it and moves through the entire space. You just have to leave your doors propped open - IMHO you don't even need the lighthouse thingys as it feels its way and moves wherever it's not blocked, but always stops at the top of the stairs. And that's the joy: you just switch it on and leave it, whenver you feel the floors need doing, and Roomba takes care of everything. Literally, ALL the effort you need to put in is to take a small sweeping brush (and yes I've found a great one of those too, thanks John Lewis!) to the few corners Roomba can't get into and sweep the bits to where it can, and that's it. Done. As well if not better than you yourself would with a conventional vacuum. Cleaning and emptying is similar in principle (no bag) but less messy than a bagless vacuum and you don't mind giving a moment's tlc to such an invaluable little household helper. Overall, I'm astonished and thrilled by its effectiveness and helpfulness and like others here, wish I'd taken the plunge and forked out for one earlier. 29 May 2014
Brilliant Product Yes a little pricey but worth it. It does a great job. Leaves carpet nice and clean and also the tiles in the kitchen. The schedule function is really useful. Every morning it sets about for 1 hour and cleans thoroughly. You'll be amazed how much dust it collects each time. Having a young baby in the house we want to keep carpet clean and this little bad boy Roomba is great. Wife has her hands full most of the day with the baby so freeing up some time goes a long way. You will have to clear out the collection tray every 4-5 days depending on how often you use it. If used daily then tray needs emptying 4-5 days. Not a big problem. Takes less than a minute. Overall we are very happy with this product. 30 April 2014
Delighted but not with IRobot Support I have been delighted with this cleaner. So nice to leave it yto get on with the vacuuming while I get on with other things and to clean better than I did. Its gets under Chests of Drawers, sofas etc. However there is no instruction book just a DVD. I would prefer a booklet rather than logging in to my computer. I have just discovered what the box thing with the clear button on the top is, bought a set of batteries but have been unable to open it. Consulted the DVD but this shows a different model so ask IRobot for help. They ask for Serial Number, then having sent this (what on earth do they need with this for such a simple question). Now they want me to send photos of my Lighthouse and where did I buy it separately. I have managed with the help of a strong neighbour to get the top off without further help from IRobot. I do hope that I will not need any more assistance from them. For an item of this cost I would have the service would have been better 28 February 2014
Expensive but worth it. We have had the i-Robot Roomba 770 Vacuum Cleaner for a couple of months now so here is the review. We researched the product and read a number of reviews most seemed positive so after some discussion we decided to get one. We have three boys a dog and cat so the house gets a lot of traffic through it with muddy shoes paws etc. Roomba has surpassed expectations in both my wife and my opinion. We have programmed the cleaner to vacuum daily after everyone has left for work or school and come back to a floor that has been vacuumed. The Roomba then goes back to its docking station to recharge when it is finished. The fact that the machine needs the floor clear to do its job to its optimum means that we have now managed to train our boys to put their shoes, school bags and other junk away with the threat of they will have to use the old hoover if they do not. The only time the old hoover comes out is when we have to do the stairs once a week. Our flooring is mostly wooden downstairs with a couple of rugs which the Roomba has no problems getting on and off to clean. The kitchen and bathrooms are tiled and again it has no problems cleaning these areas. I was sceptical at first about the Roomba cleaning the landing carpet but as it has not thrown itself down the stairs with me supervising it I am confident leaving it to get on with its job. The Roomba seems to work in a haphazard fashion but gets the whole area clean so we are very pleased so much so we are thinking of getting the mopping one later in the year for the tiled areas. The only thing I am unsure about is the handle for the Roomba as it seems a bit flimsy however it has not broken so my doubts are probably unfounded. In short if this broke we would definitely get another.  05 February 2014
Very effective vacuum 'Robert' as our vacuum is called cleans well. We have a white tiled floor and a black Labrador so lots of black hairs. Robert does a first class job. You just leave him to get on with it and the floor is left spotless. He copes well with rugs and carpet as long as the rug tassels are not too long as they can get caught up. Our only criticism is that he can miss the odd bit but to be fair we haven't read the instructions! Also good for bedrooms and cleaning under beds and cupboards. Would definitely recommend. 07 December 2013
So far soo good! Got this today & was so excited to see it in action but the info said to charge it overnight for its first charge...... I couldn't wait that long so thought I'd have a sneaky quick go. I let it do its thing for only 15 mins & although it was quite disorganised in its chosen route, it was extremely effective & sucked up so much dust and cat hair in such a short space of time (& my floors were only cleaned 2 days ago!) I can't wait to let it go properly tomorrow & see the results but I am very confident they will be great. Only neg so far is that my cats were very wary but I think they will get used to it..... They'll have to!! It is expensive but I am sure it will prove to be worth every penny. 11 August 2013
