Is 45 kPa strong enough for pet hair on carpet?

Yes. 45 kPa is high for a home upright and in the range of strong corded vacuums, so it should lift pet hair and deep carpet dirt well. Results still depend on the floor head and filter being clean.

Does it work on hardwood as well as carpet?

It is rated for both carpet and rugs and hardwood floors. On bare floors, lower the suction or switch mode if the touch display offers one, so debris is not scattered.

No. It is a corded upright with a 550 W motor, so it plugs into a wall outlet and has no battery or run time. That is why it can sustain high suction without recharging.

How does it compare with a cordless stick vacuum?

It offers more sustained suction and no battery limits, but it is heavier and tied to a cord. A cordless stick is better for quick pickups and stairs; this is better for deep whole-room cleaning.

What is the digital touch display for?

It is the control panel for power and cleaning modes, replacing physical buttons. Check that the display responds reliably, since touch panels are a common failure point on budget vacuums.

What comes in the box?

The listing does not detail included accessories. Before buying, confirm which floor heads, crevice tools and filters ship with it, since a bare-floor head and upholstery tool matter for stairs and furniture.
