Shark - Navigator Upright Vacuum - Champagne

Yes, this machine does have a Hepa filter. When you remove the debris canister to empty the unit it is easily accessible. I gently tap the filter when I empty the unit to remove the majority of the dust trapped in the Hepa filter and have rinsed it out under the kitchen faucet and allowed it to air dry a couple of times.

No, the cord wraps around the back.

For a long time if you respect it! You will need to buy extra filter's the vacuum has such a power picking up alot of dust, So I buy a couple extra filter's and hand wash them.

This vaccum is extremely light weight. It picks up all the dirt around, but be careful, it will suck up smaller items on the floor if they are too close.

It uses the same head but a different setting, when in a rug, switch it completely for the brushes spin to pick up refuse, in hardwood floors there is a mid-switch setting in which the brushes don't spin and won't damage your floors. Hope this helps
