Bissell SurfaceSense Allergen Lift-Off pet vacuum uses advanced technology which offers you a quick, automatic and hands-free transition for optimal cleaning performance on any floor type. Plus, the tangle-free, multi-surface brush roll has stiff bristles for cleaning carpet and soft bristles for vacuuming hard floors, so it can pick up everything from fine dust to larger debris. You can now easily switch from a powerful upright vacuum to a detachable, portable canister to conveniently clean hard to reach areas, high and low. This machine helps capture and hold dust and allergens 1 inside the vacuum so they don't escape back into the air you breathe with our sealed Hepa allergen system. You can feel confident tackling any mess with this versatile vacuum, and when you buy a Bissell product, you help save pets, too. Bissell proudly supports Bissell Pet Foundation and its mission to help save homeless pets. We're proud to design products that help make pet messes, odors and pet homelessness disappear. One from non-living sources.
