I don't have a name for mine... but I was amazed. I honestly thought this was going to be nothing more than an expensive fancy carpet sweeper. But no, it goes round and round for what seems an eternity, but does an amazing job cleaning, vacuuming, and even lifting the pile of my carpet as well as any upright might do.
I'm disabled with MS, so anything that saves me housework or lifting and bending and so on is a boon. This is a definite boon. I only have to bend once to set if off and once again to collect it. Just wish it did stairs! I separately bought another docking station for upstairs, so all I have to do is carry the Rooma itself upstairs, rather than the whole caboodle.
It did get a bit stuck a couple of times, in that it collected hairs around the brushes which seemed to cause it to sort of "choke". Once sorted, off it went to finish off its job.
I empty the dust container and clean the brushes each time to make sure it doesn't get clogged up. I find if I let it do the entire downstairs in one go, it doesn't do as good a job as when I let it do one room at a time, by shutting it in. When I let it do one room at a time, it spends what seems like hours at it, going round in circles till its every corner. If I let it do the whole of downstairs in one go, it seems to get lost or confused between which room to spend more time in, but still gets most of it done, just not quite as well as room by room.
I forgot to put the virtual wall in place on one occasion by a shallow step, and it fell over and called out for help, ha!
