There's been quite a few out there. at work we have a machine similar to this It's a strange thing. It's battery powered and It's brush spins backwards and the bin is on the back so things to travel up and over the brush to reach the bin. I did like our old one better which had a front mounted bin and swept things up a ramp into the bin. Both of them also have a suction motor which aren't super powerful but again more of a dust control type of thing. This one's filter is in the main bin area where the old one had a separate bin on the back housing the filter and a tray for finer debris. I'd be curious to try one of the manual suction motor models like the Eureka or the NC4 just to see what they're like.
