What the manufacturer claims
BISSELL states the 4039B uses a HEPA Sealed Allergen System and a FurFinder upholstery tool; it is tested on floors/upholstery and intended to remove embedded pet hair, dust and allergens.
A manufacturer statement is not a TailVetted test result.
Limitations
Vacuuming reduces surface debris/allergens but does not prove clinical allergy reduction. HEPA/allergen capture claims are manufacturer claims pending independent validation.
Which pet vacuum actually works depends on your floors and your stairs, not the price. How to choose one for a Canadian home, what HEPA does and doesn't do, and what to skip.
