The Dreame D20 Air Plus is the cheapest Dreame with a self-emptying station: 20,000 Pa of suction, a double anti-tangle brush, lidar navigation, a fixed mop cloth for light mopping and a station that empties the bin into a four-liter bag, good for 120 days according to Dreame. The 3,200 mAh battery is rated for 150 minutes and at 3.7 inches the robot is slightly lower than most.
At its low price this gets you the main convenience of a pricier robot: months without emptying the bin yourself, plus suction on paper above many mid-range models of a few years ago. The light equipment keeps the price down.
The limits: no obstacle recognition, only lidar and bumper, so socks and cables must come off the floor; the mop cloth does not lift on carpet and is not washed; the side brush does not extend; and the battery is smaller than in the D20 Pro Plus. None of our test sources has measured this model. For a small home with hard floors and little clutter it is a cheap way to get a self-emptying station; anyone serious about mopping should look higher.

Dreame D20 Air Plus specifications
The numbers that matter first, then every fact by group. As published by the maker or the store we read it from.
The side brush swings out in a corner or along a baseboard, so the dust there is swept in too. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.
no (assumed)
Carpet detection
When it matters
Rugs and carpets, where the robot should raise its suction.
Mopping in a home with rugs, which have to stay dry.
The robot notices when it drives onto a carpet. Most then raise their suction, and a mopping robot lifts its mop or leaves it at the dock.

Suitable for pet hair
When it matters
Dogs and cats that shed.
Long-haired pets, whose hair wraps around a brush.
Without pets, ordinary hair and dust need nothing special.
Source: derived, no source of its own · checked on Oct 2
Whether the robot copes with pet hair: a brush that hair does not wind around and a dock that empties the bin for you. Where the maker does not say so itself, we read it from those two.
yes
Dirt detection
When it matters
Entrances and kitchens, where dirt gathers in one place.
Pets that leave hair in a favorite spot.
If dirt is spread evenly, a normal pass cleans it just as well.
The pad slides out along a wall or a baseboard, so the last few inches are mopped as well. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.
The robot leaves the mop at the dock before it vacuums a carpet, so the carpet never gets wet. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.
no (assumed)
Mop refreshed while mopping
When it matters
Large hard floors, where a mop that is never rinsed spreads dirt around.
Kitchens with sticky spills.
In a small home the mop does not get dirty enough in one run for it to matter.
The robot returns to the dock during a run to rinse the mop, instead of pushing dirty water around. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.
no (assumed)
Water tank in the robot
When it matters
Large hard floors mopped in one go.
A robot whose dock does not refill it during a run.
With a dock that refills the robot during the run, the tank’s size hardly matters.
The dock mixes detergent into the water itself, from its own bottle. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.
no (assumed)
Plumbing hookup
When it matters
Mopping every day, without filling and emptying tanks.
A spot near a tap and a drain, such as a utility room or under a kitchen counter.
If the dock stands far from any plumbing, it is no use.
The dock can be connected to the tap and the drain, so you never fill or empty a tank. It does need a connection nearby. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.
