Best praise vs top criticism for Miele Complete C3

Best Praise

Some brands are EXPLICITLY designed for planned obsolescence. To me... its less of "snobbery" than it is... just not wanting to be stolen from, passively, by crappy appliances. This happens at ALL price points. I bought a used Miele C3 Cat/Dog used. I swooped in on an excellent deal. It wasn't cheap.... but the thing is truly built to last amd it DOES THE THING I NEED IT TO DO. Vacuum! I had 2 Dysons which were both expensive AND shitty. Then a Black and Decker. Then a Kenmore. It got frustrating buying reconfigured crappy vacuums. Not everyone can buy a top of the line Miele or Sebo. I get it. People who only have $100 to spend should know that Shark's plug-in models are a better quality build than most Dyson Cordless vacuums that are 3 times the price. People should warn others to NOT BUY CRAP. Not buying garbage =/= snobbery.

bag design is honestly one of the biggest flaws with the c3. we see countless c3 units that come in with misaligned bags and motor compartments full of dirt.

Bagged canister doesn't slowly loose airflow overtime, retains its air purification the whole time too. It's quieter, more efficient and has a 10 year warranty. I just got a k2 and love it.

With carpets you are going to need something with an electric floor nozzle.  The Sebo K2 and the classic C1 aren't going to cut it, though their suction is exceptional.   Kenmore will be your best bet, and consider a bagged Hoover for budget buy.
