A hotel housekeeping shift can stretch across dozens of guest rooms before lunch, with stairwells and hallways in between. The Bissell BigGreen ProBag Upright Commercial Vacuum, model BGU1451T, keeps up with that pace. It is light enough to carry between floors, and its bagged design holds dust inside when you finish one room and move to the next. Key Features and Benefits of the Bissell BigGreen ProBag 13-in Upright Commercial Vacuum Cyclonic Airflow: Cyclonic airflow moves up to 95 CFM with 9.5 inches of water lift, pulling embedded dirt out of carpet and grit off bare floors. Wide Cleaning Path: A 13-inch cleaning path covers more floor with each pass, so you finish large guest rooms and corridors in fewer strokes. Multi-Stage Filtration: Pre-motor and post-motor filters work with the vacuum bag to create 3 filtration stages, which trap dust before it reaches the motor or the room. Height Adjustment: A 5-position height adjustment matches the brush to the surface, so you can go from bare floors to deeper commercial carpet with the same machine. Portable Build: At 12 pounds with an easy-grip carrying handle, the vacuum is simple to lift up and down stairs between floors. Long Power Cord: A 30-foot power cord gives you a wide cleaning radius, so you switch outlets less often in long hallways. Quiet Operation: Running at 67 dB, the vacuum keeps noise down when you clean near occupied guest rooms or offices. Included Attachments: A crevice tool, combination dusting brush/upholstery tool, and extension wand ship with the vacuum to help you reach edges and upholstered furniture. Flexible Hose: A 6-foot hose lets you work on baseboards and stair treads without repositioning the vacuum base every few feet. Bag Change Indicator: A bag change indicator tells you when the bag is full, and the front-mounted bag door makes swaps quick between rooms. Motor and Power: A 1,200-watt motor draws 10 amps at 110-120 volts, so you can run it from standard wall outlets in guest rooms and apartments. ETL Certified: ETL certification confirms the vacuum has been tested to recognized electrical safety standards, which supports its use in commercial settings. Matching the ProBag to Your Cleaning Route Before you put the ProBag on a cleaning route, make sure the job is dry debris only. It handles dust and tracked-in grit on all floor types, but it is not made for wet spills or liquid pickup, so keep a separate method ready for those messes. The bagged collection system suits occupied buildings, and the front bag door gives you direct access to the bag for changing between rooms. For storage, the vacuum measures 12 x 13 x 41.25-Inches (L x W x H), so it stands upright in a housekeeping closet or next to a cart without taking much floor space. Sylvane's Expert Take If you run housekeeping for a hotel or lead a crew cleaning multi-story apartment buildings, this vacuum suits routes where you carry the machine as often as you push it. It does best in tight guest rooms and on stairs, where a heavier wide-area machine slows you down. The 2 features to rely on are the low noise level and the front bag door, which let you work near occupied rooms and swap bags cleanly. For daily multi-room carpet care, it belongs on your cart.
