Pros & cons

Miele Guard L1 Cat & Dog

  • Sealed bag system with self-sealing HyClean bags — dust-free disposal
  • Active AirClean charcoal filter noticeably reduces pet odors
  • Outstanding suction with 1200 W motor and quiet 75 dB operation
  • 36 ft operating radius covers large floors on one outlet
  • TurboTeQ head lifts pet hair from rugs and low-pile carpet
  • Early professional reviews rank it among the best canisters ever tested
  • $899 is a lot to spend before the platform has a long-term track record
  • Air-driven turbo head — deep-pile carpet wants an electro-brush instead
  • Bags and filters are a recurring cost
  • Warranty is 3 years, shorter than Miele's old 7-year motor coverage
  • Heavier than the Classic C1 at 15.7 lbs

Sebo Airbelt K3 Premium

  • 175W ET-1 electric power head genuinely deep-cleans carpet, not just suction
  • S-Class hospital-grade filtration with a sealed 3-layer AeraPure bag
  • Smaller, lighter chassis than Sebo's full-size D and E canisters
  • 10-year motor/parts, 7-year labor warranty available through Sebo's dealer registration program
  • Rubber-coated wheels and Airbelt bumper protect furniture
  • Quiet 63 dB operation for the suction it delivers
  • Dealer-only purchase - Sebo discourages buying through Amazon marketplace sellers
  • 37 ft operating radius is shorter than the full-size D4's 52 ft
  • Bags, filters, and brush strips are recurring costs
  • Smaller 0.8-gallon bag than the D4's 1.5-gallon capacity
  • Manual height adjustment on the power head, not automatic
