I have cats and dogs and ALLERGIES! This ingenious device is worth every penny - the ability it has to remove dust and dander from surfaces is amazing!!! The headlight on not only the base but also on the attachment is brilliant! You can actually SEE the dust you normally would not with a regular vac. This is truly a wonderful machine, it senses what surface it's cleaning (carper+hardwood floor) you don't have to adjust anything!! I love, love, love my Bissel SurfaceSense® Allergen Pet Lift-Off® Vacuum! It has improved my sinuses like I didn't know possible! Its so easy to transport around the house, you can even bring it to your vehicle, the attachments make it super easy. TRY THIS you WILL love it!!
