Latency removal from liquid screed.

Hi all. The company who laid my screed offer a sanding service but they said the sander doesn’t have a built in vacuum. As this house is lived in and I’m already getting agro off the Mrs, I need the sanding to be the least messy as possible. I’ve seen some images of machines that look like they have a built in vacuum. Are there companies out there that offer a sanding service with this less messy option? Does anyone know of any in the Leeds/Bradford area? Cheers.
