Only three words - Shark Navigator Lift away.

These are the absolute BEST vacuums on the market. It the ONLY one that would pick up ALL the labrador hair. Dyson Animal was returned after 2 weeks later (awful, awful vacuum that would not pick up anything on carpet).
Shark stands behind these and the 5 year warranty is real. After hose rip just beyond the 5 year mark they sent a new one, no questions asked.
