Received my Pet Hair Eraser last week. Assembly could not have been any easier. You immediately feel the resistance from the wand on the carpet. This is the immense vacuum pulling the wand to the floor. My previous vacuum was a high end Shark. I could not finish three rooms without stopping to remove hair tangled onto the brush. This Bissell made the entire house, two bedrooms, three offices, and our daycare. Not one strand of tangled hair. I strongly recommend the Pet Hair Eraser.
