Yep, we're digitizing huge amounts of old files and shredding the paper files afterwards. Two reasons. One, data on paper has to be transferred by hand to spread sheets if any kind of data analysis is going to be performed. But, if you copy paper docs and put them into certain formats, you can generate spreadsheets out of printed data tables and then perform the data analysis you wish. It also makes the data searchable and more easily available to users in our profession. We are creating a data library this way.
We had three summer interns in a room with three cross-cut shredders going to town. Most of it went in plastic bags but a lot went on the floor which is covered by a low pile commercial carpet. The Sanitaire choked on the stuff, smeared it into the carpet and started to smell like it was burning. We sweet talked the lady who cleans our spaces and others in our building to come back and clean up the mess. She has a knackered looking Windsor Sensor S12, Windsor's least costly model. A few passes and all the mess the Sanitaire couldn't pick up were gone and the carpet was spotless again.
Keep in mind I am not a fan of any upright. I prefer a canister vac and a good powered floor brush. But for cleaning vast stretches of office carpet I can see the utility of an upright. They load on the cleaning cart easily too.
Low pile and/or commercial carpets is where Winsor and Sebo uprights excel. In deep pile carpeting the suck right into the carpet, which ought to be desirable, but the silly belt sensor always shuts them down misinterpreting the drag from deep pile carpet as a belt jam. If I could find a work around for the sensor I would be much more enthusiastic about them. But the Sanitaire is weak, weak, weak. I really do not understand why custodial crews buy them other than they are extremely inexpensive. Windsors and by extension Sebos clean so much better. Seeing the Sanitaire jam, smell like it was burning and seeing the shreds smeared into the carpet, followed by a few passes of this hammered looking Windsor cleaning the carpet thoroughly was enough of a lesson for me.
