Having had this now for a month or so I have this scheduled to nip round the downstairs every other day and it does a decent job of picking up dust and whatever has been dropped on the kitchen floor. I still need to get into some areas with the Dyson and do the stairs but this has massively reduced the frequency I need to do this.
This is mainly over wood / laminate floor but also does a decent job in the front room over carpet and the play room over a rug (albeit a thin one). It gets in to most places and even under the range cooker but emptying is a bit old school and possibly the only criticism I could aim at the product.
My main concern was the 2cm drop between the kitchen and the hall and I glad to say this can happily cope with bumping up and down this. I have read various reviews of Roomba being unable to cope with uneven floors so I went for the Neato and I am certainly not disappointed.
The only other concern was the burglar alarm but being pretty small and low to the ground this happily avoids all the sensors.
