Pros & cons

Miele Guard L1 Electro

  • SEB228 electric brush genuinely rivals an upright on carpet, unlike the air-driven turbo heads on cheaper Guard L1 trims
  • AirClean Plus filtration rated for 99.99% fine dust retention
  • Self-sealing HyClean bags keep disposal dust-free
  • 36 ft operating radius covers large rooms without replugging
  • Rubber-coated swivel wheels and a soft bumper protect furniture
  • Made in Germany with Miele's usual overbuilt fit and finish
  • $1,229 is the most Miele charges for a canister in the US
  • 3-year warranty is shorter than the Classic C1 line's 7-year motor coverage
  • Electrobrush height adjustment is manual, not automatic
  • Bags and filters are a recurring cost
  • HEPA-grade exhaust filter is an optional add-on, not standard

Sebo Airbelt D4 Premium

  • 1.5-gallon bag and 52 ft cleaning radius - the biggest capacity in Sebo's US canister lineup
  • 175W ET-1 electric power head genuinely deep-cleans carpet
  • S-Class hospital-grade filtration with a sealed 3-layer AeraPure bag
  • 320° swiveling hose and 180° steering ease maneuvering a full-size canister
  • 10-year motor/parts, 7-year labor warranty available through Sebo's dealer registration program
  • Automatic obstruction shut-off and LED suction indicator
  • $1,449 is among the most expensive canisters on the site
  • Dealer-only purchase - Sebo discourages buying through Amazon marketplace sellers
  • Bags, filters, and brush strips are recurring costs
  • At nearly 16 lbs it's noticeably heavier than the compact K-series
  • Power head height adjustment is manual, not automatic
