Didn't catch the jokes etc, other than it's voice was 'loud' from across a big building. Just watched some videos of them, and I recon they'd be great fun at the Uni, but we can't spend that money on cleaning kit, all be it cool and a big 'hit' - it was an external company having a conference using our facilities as student's have gone home.
PS Our cleaning staff are ace in our building, it's spotless, and all done by 8am, so a fancy robot wouldn't be seen. Our team are outstanding. They have really taken pride in the building since it was built 8 or so years ago. They do us proud, and that's with stinky students in it.
