Ok – it’s not really about development but if you live in house without deep pile or shag carpeting, you owe it to yourself to take a look at this thing.
It’s been around for a while but is getting more and more press. I bought one through Hammacher Schlemmer (who offers a lifetime guarantee) and have to say: what a great device.
Turn it on and let it run! Walks away from stairs and cleans fairly well. The dogs ignore it (which is a miracle if you know Muffy) and it hits those areas that you never even think about during cleaning.
If only it did stairs…
