Miele Boost CX1

The Miele C3 Cat and Dog is better than the Boost CX1, Iabasiac has a great video on the [Boost Miele's bags will last 2 months on average, so you're looking at 6 bags a year and 1 hepa exhaust filter a year.

Cordless vacuums will eventually wear out their batteries. Users that have Miele Blizzard CX1 vacuums have shown the dirt separation isn't as good as the competition so it ends up clogging the filters faster and the dirt bin is messy to empty.

Miele's bagless machines really aren't their strong-suit, to the point that a lot of folks would call them 20 years behind the rest of the market. Biggest flaw to the Blizzard CX1 models is their inaccessible exhaust filters that'll clog up over the vacuum's life. With this maintenance-unfriendly design, I can't really consider this a buy-it-for-life machine.

Avoid the Miele Blizzard CX1, the cyclone and filter aren't the best and it's been discontinued. If you're looking for longer-lasting, I like Sebo a little better than Miele although Mieles are still great vacuums. Sebos have sturdier parts in a few key areas, they're easier to service, and they'll sell replacement parts directly to you.
