The best robot vacuum. When I am tired or when I cannot vacuum. The Roomba does the job very well. When I was watching TV one time I set the Roomba to do the work. About 3 hours later I checked to see how the Roomba was going on my floors were spotless. The Roomba picked up everything and I was super impressed. It gets along edges very well with its side brush and the battery is very long lasting. This is a very good robot vacuum.

Works reasonably well but doesn't keep a straight line.
Works well on most surfaces.
If you hit a wet patch there is NO support; they will try to sell you another unit even if the repair should be simple.

We have had two previous models of the Roomba and this one simply isnt as good as the other (older) models. It doesnt map the rooms as well as the older ones and doesnt seem to cover the entire house, missing entire areas time and again.

It does however do a great job of collecting the dust and dirt from the places it DOES go, but seems to seek out electrical leads to get tangled with and finds ways of getting caught in corners where it gets stuck.

Past models were flawless, so this one has been a bit of a disappointment and will probably stop us buying another iroomba.

I realise it was a model that had been discontinued when we bought it, but that should not have made any difference to its effectiveness as it was a new machine.

This is a hardworking vacuum cleaner. It’s smart enough to go throught thr edges of the wall. It does love to eat cables so i need to ensure the cables are not on the floor. I’ve hard it more then 3 years but i havent even replaced the batteries. This has made my house chores a lot easier. I also speaks a lot of languages

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.

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.

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.
