Miele 12878470 Triflex HX3 Cat & Dog Cordless Stick Vacuum in Obsidian Black
Meet the Miele Triflex HX3 Cat & Dog Obsidian Black cordless stick vacuum cleaner, manufacturer model 12878470, built for thorough floor care in homes where pet hair, allergens, and everyday messes demand flexible cleaning. Its Digital Efficiency Motor and Vortex Technology generate high suction, while FloorDetect recognizes the flooring and adjusts power as you move. BrilliantLight casts a bright LED beam ahead of the floorhead to help reveal dust that could otherwise be missed. From routine hard-floor care to heavily soiled areas, this cordless system brings focused cleaning performance throughout the home.
The convertible 3-in-1 concept allows the PowerUnit to shift with the task, transforming among Comfort, Reach, and Compact arrangements for floors, extended access, or quick handheld work. An exchangeable Li-ion battery supplies up to 70 minutes of running time for large-area cleaning under the stated test condition.1 When concentrated dirt needs more attention, Boost mode adds extra power. The clear display keeps the active cleaning mode, battery charge, remaining cleaning time, Boost timer, and charging percentage visible, while the free-standing park function makes short interruptions and upright storage more convenient.
Key Features
Patented 3-in-1 Design
Positioning the PowerUnit near the floor creates Comfort mode for lighter handling. Move it higher for the maneuverability of Reach mode, or use PowerUnit Solo in Compact mode for fast handheld cleanup. This patented architecture adapts one vacuum to changing jobs around the home.2
Maintenance-Free HEPA Lifetime Filter
Created for households sensitive to allergens, the filtration system achieves 99.999% appliance filtration performance and is classified as HEPA under the stated standards.3
Cleaning Information At A Glance
The display identifies Low, Eco, High, and Boost operation while tracking remaining battery charge and cleaning time. It also reports the Boost countdown and charging percentage, so essential status information stays easy to follow.
Specialized Care For Floors And Furniture
A soft woven nylon roller allows the Hardfloor Care Tool to travel gently across delicate flooring. For upholstered furniture and seats, the compact HX-EC 10 powered brush targets embedded debris and pet hair without requiring the full-size floorhead.
