The 8,000 Pa suction actually pulls crumbs out of the carpet pile instead of just skimming the surface. I mapped my downstairs once with the iPath navigation and it hasn't bumped into the same chair legs since.

The auto-detangling roller brush is a genuinely brilliant touch — with two long-haired cats I was bracing myself for constant untangling, but I haven't had to cut a single hair off it in three weeks. The 8,000 Pa suction also pulls up tracked litter from deep in the rugs, not just the surface.

The auto-detangling roller brush is genuinely handy with two long-haired cats, but the mop leaves faint streaks on my tile unless I run it twice. Navigation works fine, though it occasionally bumps the same chair leg.
