This thing is stupid powerful. For once, I didn't go cheap. I wanted something, I dunno, nicer. It's especially good for extracting pet hair. Don't have pets, but I am a hairy bastard, so...
I have both a Miele canister similar to your pic and a cordless Shark Rocket. The Rocket:
- is easier to move around the house
- has a reusable dust collector that is easy to empty
- has reusable filters that just need to be cleaned once a month or so
- doesn't get jammed by hair
- was somewhere around 1/3 to 1/2 the price of the Miele
Whereas the bulkier and more expensive Miele unit has disposable bags and filters, and the brush head (that I had to buy separately for close to the price of the whole ass Shark vacuum) is constantly jammed and needs to be completely disassembled to clear it.
