Is it good for pet hair on stairs?

Yes. The rubber nozzle is designed to grip hair from carpet and fabric, and the corded motor keeps suction steady across a full staircase.

Does it need a battery?

No. It plugs into a standard 120 V outlet with a 16-ft cord, so there is no charging and no power fade.

No. It is for dry debris only, such as pet hair, litter and crumbs. Use a wet/dry vacuum for spills.

The bin is small, so empty it after each heavy session. Light touch-ups may go a few uses.

Yes, the HEPA filter is replaceable. Rinse or tap it per the manual and replace it when suction drops or it looks clogged.

It weighs about 5 lbs, which most owners manage one-handed for short jobs, though long sessions on a ladder can tire the arm.
