Question: how often does this fail to return to the dock? My XV neato would fail 2 out of 3 times...
Document: (Original: 3 stars) I have a signature Pro XV and I love it (much more so than the Roombas I have). However, the 80 doesn't work for me: Instead of returning to base, it returns to within about a foot or so of the base, facing the wrong way, and then stops. This is a problem - one of the advantages of the Neato is meant to be that it can clean a bit, return to base, recharge, and continue. So that's broken.
Simply amazing. I have the Neato clean every day when I'm at work and when I return I have cat hair free house. Not as much as a speck on the floor. It has gotten stuck just a had full of times in the past 3 months but considering it cleans the house every day, my house has never been cleaner. Superior product compared to others I have tried.
This problem causes the Neato to lose a star.Returning to home base for charging. The Neato XV-21 had issues here and the Botvac is not different. It manages to return to the charging station only one out of three times. It tends to 'forget' where the base is at and then it cannot properly find it again. Neato advertises that their machines and detect the charging station but this does not really seem to be the case.
I  really wanted to like this machine. 3 times (I'll explain). After reading the original CNET review and watching the demo of the Neato XV Signature Pro, I got my first neato. It didn't work out of the box - there were error messages as soon as I turned the machine on. Neato thought it might have been a battery problem and sent me a new battery pack, but that failed to solve the problem and I returned it.A few months later, I bought my second neato.
I didn't buy this through amazon, but I did pay full price and apparently I missed a $100 off sale at major chain. But regarding the sale price, this thing cleaned so well, im not even mad that I missed it.I have two cats and hardwood and carpet. My floor is literally the cleanest ive ever had. A couple of things to point out.When you first get it, the instructions say to discharge it completely the 2-3 times.
I had few problems with the XV-21, and rate it high, but this works much better. It covers 2 times the area and the side brush is catching the stuff my XV-21 has been missing for a year.Update after 2 months I'm getting an error "left wheel is stuck" ill,get with customer support,this week to see if this is fixable or a warentee issue. More to comeUpdate, my experience with their customer service was excellent.
This is my second Neato robot vacuum, having purchased a XV-14 model several years ago. Now that the XV-14 was getting a little &#34;eccentric&#34; and I wanted to add 2-floor capability for a larger house, I decided to add to my growing fleet of robot workers.
Since Amazon is now offering the Neato Botvac, I ordered the model 80 and will see if this does any better. Hopefully the new Neato will last longer than the XV-21 (which I truly believe was a rebuild). Whichever one proves better for my needs I will keep and the other will be gifted to my mom. The Roomba is not so bad as to return, it just fails where I need it most.
I bought the Neato 80 about a month ago (not through Amazon, it wasn't available then). I'm giving it 4 stars (so far) because it does  do what it claims to do. I'm holding off on 5 stars for two reasons:  1) I want to see how it holds up over time, 2) Mine is rather noisy, especially when turning.It definitely took the machine a few times to get the lay of the land.
Excellent product, does what it is ought to with excellence. The plotting algorithm is quite smart and it finishes my 2 bedrooms/2 bathrooms 70m2 apartment in 30~40 minutes. It's programmed to work daily around 3pm, so I don't see it moving very often. But I do have to clean it's bag every three days if I want it to run smooth on the fourth, which is proof of how much it is aspirating.
Answer: The first few times it failed. It even made it back to within 6 inches and circled around beeping. But we we picked everything up and blocked off the couch and left for 3 days (6 cleaning cycles I suppose) and came back to clean floors and it docked. So if we do our part it does fine.
