In-depth review

What it's like to own

The L40 Ultra Gen 2 is Dreame's best-selling all-rounder. Both the side brush and one of the spinning mops swing outward to reach corners and under cabinet edges, which owners single out as its best trick.

25,000 Pa of suction with four carpet modes, 10.5 mm mop lifting and structured-light obstacle avoidance make it comfortable in mixed-floor homes. Its 5,200 mAh battery is rated for up to 231 minutes (about 1,679 ft² in quiet mode).

The dock empties the bin, washes the mops and dries them with hot air; an auto-detergent module is an optional extra. At $500 (from $750) it's one of the best-reviewed all-in-one robots in its price range, with 84% 4–5 star ratings.

Pros

  • Extending side brush and mop for corners
  • 25,000 Pa with carpet modes
  • 231-minute runtime
  • 3-year warranty, sold by Amazon

Cons

  • Detergent dispenser costs extra
  • 2.4 GHz Wi-Fi only
  • One long-term owner wants more battery

4.3★ from 612 ratings (84% 4–5 stars). Owners praise the strong suction, even mopping, corner cleaning and slim dock. A two-year owner wishes the battery lasted longer. Former Roomba users say it's a big step up.
