What is a sealed filtration system?

It means the air path is sealed so dust stays in the canister and filter instead of leaking back into the room. That helps with allergies and pet hair.

Does it have a retractable cord?

Yes. The cord rewinds into the body at the push of a button, so you do not coil it by hand.

Is it good for carpets?

It is built for everyday surface cleaning. The compact canister and small capacity make it less suited to deep cleaning wall-to-wall carpet in large homes.

How often will I empty it?

More often than a full-size canister, since the body is compact. Plan on emptying it after most cleaning sessions in a busy home.

Is it worth it over a full-size canister?

If storage space and easy carrying matter more than capacity, the compact body and sealed filtration make it a sensible pick. For large homes or heavy carpet, a full-size canister holds more and cleans deeper.
