Rubber Blade Friction Scraping for Entangled Pet Fur Extraction
Rex says

"Dragging a dry rubber window squeegee across low-pile carpets, rugs, and fabric couches pulls up clumps of deeply embedded dog and cat hair that vacuum cleaners leave behind."
The science
-
Contact charging does half the work
Rubber sits toward the electron-gaining end of the triboelectric series; nylon and polyester carpet fibers sit toward the losing end. Dragging one across the other separates charge, so the blade holds fine hair electrostatically. Zou et al. ranked these polymer pairings quantitatively, and squeegee-on-carpet is a strong pair - which is why hair jumps to the blade instead of staying in the pile.
-
Edge shear does the other half
Pet hair tangles laterally around fiber crowns. A vacuum pulls perpendicular to that wrap and tightens the knot. A blade edge wedges under the mat and drags it along the nap, unwinding it instead. That geometry, not suction power, is why a two-dollar squeegee recovers hair a good vacuum leaves behind.
-
It only reaches the top few millimeters
The blade works the pile surface. Hair driven down to the backing, or buried in a dense looped pile the edge cannot enter, stays put. Expect real returns on low pile and almost none on shag. On loose weaves the same shear that unwinds hair will also pull yarn, so test an edge first.
Do it right
Work dry. Short overlapping pulls, all in one direction along the nap, then roll the collected hair off the blade by hand and vacuum what you loosened. Wetting the blade kills the charge and smears dander into the pile.
