Pros & Cons Side by Side

Dreame R20 Cordless Vacuum

25,000 Pa suction is the highest of any reviewed cordless vacuum — industrial-level domestic cleaning
70-minute runtime with two batteries covers very large homes in a single session
LCD screen displays remaining battery, suction mode and filter status in real-time
Flexible wand bends 180° for under-sofa and behind-toilet cleaning without stooping
HEPA filtration captures 99.97% of particles including fine allergens

Dreame brand less established in UK than Dyson for warranty confidence
25,000 Pa at full power drains battery faster — runtime at maximum is lower than quoted
No laser detection — cleaning thoroughness is visual estimation

Miele Complete C3 Silence Canister Vacuum

66dB at maximum power — the quietest high-suction vacuum available
AirClean sealed system retains 99.9% of all picked-up particles
German engineering — Miele vacuums are independently tested to last 20 years
1,200W motor with 6-level variable suction — full control for delicate surfaces
Hygiene AirClean bag with automatic closure — dust-free emptying

Corded canister is less convenient than cordless for quick cleans
Bulkier to store than stick/cordless alternatives
Bags are an ongoing cost — though the vacuum will outlast any cordless
