Miele Triflex HX2 Pro/Cat & Dog vs Duoflex HX1

The Miele Duoflex HX1 and the Miele Triflex HX2 Pro/Cat & Dog represent the full gamut of Miele's cordless vacuum offerings. Despite being the smaller sibling, the Duoflex is actually the better choice overall. It features superior build quality thanks to the use of more premium-feeling plastic on the power unit and a metal wand that increases rigidity. It's also more versatile; some variants include an extension hose and a flexible, extendable crevice tool for cleaning hard-to-reach places. Finally, performance is better on every surface type, and pet-hair pick-up is a breeze. The Triflex does have a couple of extra features, though, like a light on its floorhead for illuminating tough-to-see areas and a second, hot-swappable battery to extend cleaning time.
