Dreame D20 Plus vs Dreame D20 Air Plus
Quick take: The Dreame D20 Air Plus costs $40 less; the Dreame D20 Air Plus has stronger suction (20,000 vs 13,000 Pa); the Dreame D20 Plus runs longer per charge (285 vs 150 min).
Which one to buy
Suction is the whole question here, and the D20 Air Plus now wins it for $40 less, $270 against $310. The D20 Air Plus is rated at 20,000 Pa against the D20 Plus's 13,000 Pa, and almost everything else on paper matches: LiDAR mapping, a self-emptying dock, hot-water mop washing listed in the dock, auto mop lifting, carpet detection and the same 3-year warranty. The D20 Plus has the bigger dock bag, 5 L against 4 L, and the Air Plus's bag is rated for 120 days.
What owners say lines up closely too. D20 Plus owners praise its anti-tangle brushroll with long-haired pets and say it clears hair in one pass on hard floors and low-pile carpet. D20 Air Plus owners in multi-dog homes report the anti-tangle design mostly works, and they single out its navigation: precise edge-following and slowing down around furniture legs rather than bumping them. On the downside, both groups describe the mop as a light passive wipe that can't lift dried spots, and both say you need to pick cords and clutter off the floor first, since neither recognizes obstacles the way a camera-equipped robot does. Air Plus owners add that it bunches lightweight rugs and is louder than premium robots at full suction.
So the D20 Plus's extra $40 buys a bigger bag and a longer rated battery, not carpet muscle. If your floors are mostly hard or low-pile and your goal is daily pet-hair pickup, the D20 Plus does the job owners want and empties less often. If you have thick carpet or a double-coated dog that sheds into it, the Air Plus's higher rating is the reason it exists, and it is now the cheaper of the two.
Dreame D20 Plus
The better pick for mostly hard floors and low-pile carpet with pets; owners rate its tangle resistance highly, and its 5 L bag is the larger of the two.
Dreame D20 Air Plus
The better pick if you have thick carpet or a heavy-shedding double-coated dog, where its 20,000 Pa rating matters, and it now costs $40 less.

Dreame D20 Plus vs Dreame D20 Air Plus: common questions
Is the D20 Air Plus a better buy than the D20 Plus?▾
For carpet, yes, and it now costs $40 less. The Air Plus is rated at 20,000 Pa against 13,000 Pa and otherwise shares the same dock features and 3-year warranty. On hard floors and low-pile rugs, owners of the D20 Plus already report one-pass pickup of dust and pet hair.
Does either one mop well enough to replace a mop?▾
No. Owners of both describe the mopping as a light, passive wipe that handles dust and fresh spills but not dried or sticky spots. Treat it as upkeep between real mopping sessions.
Do I still have to tidy the floor before running either one?▾
Yes. Owners of both models report jams on cords, toys and other small clutter because neither has camera-based object recognition. D20 Air Plus owners also mention lightweight rugs getting pushed or bunched.
