The Sanitaire SC9180D MULTI-SURFACE QuietClean is a dual-motor commercial upright vacuum built for demanding environments. The dual motor system drives suction and brushroll action independently, enabling multi-surface cleaning with the brushroll switched on or off for carpet and hard floors. HEPA filtration captures 99.97% of particles at 0.3 microns. The 50-foot quick-change cord reaches across large spaces with minimal outlet changes. Bag changes are fast and low-mess with the quick-change disposable dust bag system. A 13-inch cleaning path covers floor area efficiently. The clog-free intake handles larger debris without stopping. Sound level supports daytime use in occupied spaces and meets LEED daytime cleaning requirements. CRI Green Label certified. Includes telescopic wand dusting brush for above-floor cleaning.
