dreame L40 Ultra A: what works, what doesn't?
What works well
- TriCut against hair: the brush cuts through wound-up human and pet hair and directs it into the bin, no more manual pulling out
- 24,000 Pa suction: a high value for cat litter, crumbs and hair, adjustable in 5 levels via app
- Mopping right into corners: the pads extend up to 4 cm and reach stains under furniture and in tight corners
- True self-maintenance: the station washes the mops, empties the dust and charges in idle times, with little effort on your part
- Carpet protection: mops lift up to 10.5 mm when a carpet is detected, and no-go zones can be set up
Points of criticism
- No dust bag documented: the station washes and charges, but an automatic dust bag as on pure suction stations is not listed in the specifications
- Refill fresh water: for the 20 spray nozzles of the mop cleaning, clean water must be available regularly
- Purchase price: around €350 is a deliberate investment for a single or small household

Build quality & everyday use
What carries the dreame L40 Ultra A in everyday use: TriCut against hair (the brush cuts through wound-up human and pet hair and directs it into the bin, no more manual pulling out) and 24,000 Pa suction (a high value for cat litter, crumbs and hair, adjustable in 5 levels via app). We have to be honest about the weaknesses: no dust bag documented, as the station washes and charges, but an automatic dust bag as on pure suction stations is not listed in the specifications.
If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.
