Dreame L40 Ultra (Vacuum and mop with dock) review 2026

A near-match for the Roborock at a lower street price, with a mop that extends into corners and pads that detach on carpet

Is the Dreame L40 Ultra Worth It?

Best mop-and-vacuum value at the top end. The L40 Ultra trades a little carpet performance for smarter mopping and a lower price, and on sale it is the better buy of the two flagships. Homes with more carpet than tile should still take the Roborock.

Dreame L40 Ultra Pros & Cons

Pros
  • 92% debris recovery; edge mopping reached the skirting boards
  • Leaves mop pads at the dock for a carpet-only run — no damp edges
  • Avoided all three obstacles
  • Often $200–$400 below list
Cons
  • Suction rating lower than Roborock; a touch less on medium carpet
  • App is busier and less polished
  • Big dock

Why it scored 8.4

The L40 Ultra trades a little carpet performance for smarter mopping and a lower price, and on sale it is the better buy of the two flagships. Homes with more carpet than tile should still take the Roborock.

Where it loses

Carpet pickup, narrowly; app.

Still the right pick for

Hard-floor homes that mop.
