This little vac is very handy, a tad noisy but useful.
You need to ensure it has a clear run with no little kids toys in the way or else it gets very stuck.
It’s great to schedule everyday to tidy the floors. We mainly use it on timber floors and it works well. Carpet is not a challenge for it.

The return to dock function is very useful.

We have multiple Labradors and my experiences have been that the 860 is not as good at picking up pet hair as the 780. Hair is often rolled into 'cigar' shapes and left behind as little deposits on the floor. Also, much of the hair and dirt does not go into the collector, but rather gets trapped between the rollers causing the full light to come on. This doesn't happen all the time but does happen regularly.

Very happy with my purchase and it cleans well. I can do lots of other things int he meantime and my apartment's carpets are always spotless. It glides easily on the carpet and is also easy to clean, I have not experienced any problems with this device so far and will gladly recommend it to a friend.

We are very impressed with the Roomba 860's ability to handle pet hair. Our dog sheds a lot and we use it every other day. Any hair that it can't handle, it whips into a ball for us which is easier to then pickup. It works really well on dust and dander and is great at detecting spots that need extra attention. Easy to empty and operate. It has trouble finding its was back to the dock, but it is a huge time saver in our house and we love it.

Our Roomba worked for a while but started to stop only after 90 secondes saying to clean brush cage. Brush cage are perfectly clean! Did contact support who told me to clean sensor (thanks, I know, it's shiny!). RE-re cleaned sensor, did not fix anything. They told me to buy new brush cage....(115$) which I did (Why why why?). Did not fix anything!
Conclusion:
DO NOT BUY IROBOT
Will work fine for a while then become USELESS!
After sell service is ZERO!
They are over brands out there!

It's a pretty smart vac, but after a year of using and regular cleaning, its run time started getting shorter and shorter until one day it finally stopped working. Very sad as I like how much dust storage it has compared to other robot vacs. It is also easy to empty.

I won this in a golf tournament, I didn't think much of it but decided to give it a go, my wife loves the idea of it. It tends to get stuck down our hallway but after a quick kick it starts back up, it's very quiet.
A great little investment if your looking to save time!

With toddlers and pets around the house, it's always important to have a clean floor. We got ourselves a Roomba 860 and it keeps our floor spotless clean and gets rid of the fur without it getting stuck since it has got no brushes in it.Though we have to declutter first before using it, overall, it's nice.

This product was nice and it cleans/picks up minute particles as well. This product is really helpful and is light. Can be easily moved about room to room or you can let it loose in the whole house and it will return to base for recharging. Hope it works fine for couple of years.

I have had this Roomba now for almost 3 years, it is being used a lot and even with dogs and cats it is doing a brilliant job. I am certainly very happy with the suction, it is easy to maneuver and in my opinion, quiet enough. It performs as well on timber floors as on tiled areas, carpets and rugs. I have just bought an i-Robot floor mop...

This vacuum does everything I expected of it. After a Neato, which I considered useless and returned, I bought the Roomba with some trepidation. However, I have been pleasantly surprised. This vacuum battles a big house and 5 hairy dogs (don't ask), and does it pretty well. Not perfect, but hey, it saves me having to get the big vacuum out every day, and that is all I want. Would I buy another Roomba 866 if it died tomorrow? Yes.

does everything it promised and its just fun to whatch and entertains my dog all day plus picks up all his hair and annoys the hell out of my friends cat plus with the new quadrent sensors I can concentrate it on the right spots its perfect for a single male

It is light, it saves your back, it can be easily moved about room to room or you can let it loose in the whole house and it will return to base for recharging. It is used in my home on carpet and wooden floors and works well for both. From time to time a deeper clean may be needed on the carpet, but for regular use it is excellent.

The roomba itself is awesome. I used to tell everyone to buy one, they won't regret it.
Now I hesitate.
11 months old, still under warranty, the spinning brush broke. 3x Harvey Norman staff and one call to the company all telling me it's not covered under warranty, it's 'a consumable'. Despite me referring to Australuan Consumer Law that a reasonable person would not expect any part to break within a year, they would not budge.
I am now in the process of referring the issue to my Territory (NT) Fair Trading office, to see what happens.
So buyer beware.
