Recently in my travels in the midwest (i.e. Tom Gasko's state of Missouri), I have been seeing more bagless vacuums used at hotels. At a boutique hotel, Hoover Commercial Bagless Hush Upright Vacuums were being used (similar to http://www.costco.com/Browse/Product.aspx?Prodid=11519346&whse=BC&Ne=4000000&eCat=BC|103|4716|28521&N=4009938&Mo=24&pos=1&No=7&Nr=P_CatalogName:BC&cat=28521&Ns=P_Price|1||P_SignDesc1&lang=en-US&Sp=C&ec=BC-EC24713-Cat4716&topnav=).
At an Embassy Suites hotel, they were using a bagless Bissell in the lobby, a lightweight Sanitaire SC9050 Duralite Lightweight BAGGED Upright Vacuum on my floor, and I spotted some bagged Orecks on other floors.
At a small hotel, they were still using very old commercial Hoover Elite bagged vacuums.
There does seem to be a trend towards bagless - even the dreadful bagless with a filter in the dirt canister.
Interesting article on energy efficiency of vacs in Europe, sorry if this is a repost:
http://ec.europa.eu/energy/efficiency/studies/doc/ecodesign/eup_lot17_final_report_issue_1.pdf
The report is somewhat critical of the trend towards cheap bagless vacuums with high energy consumption and not so great performance.
The smart tyrant writes his own story to ensure that it is favorable. The lazy will repeat lines from the book without fact checking.
