About
What it is.
Dreame's X40 Ultra sits in the Vormax line of robot vacuums, combining vacuuming and mopping in a single cordless unit built around a self-cleaning dock. The station handles washing, drying, and emptying duties automatically, while SideReach and MopExtend RoboSwing extend the cleaning path into edges and under furniture that fixed-arm robots typically miss.
It suits households that want an established maker's take on the all-in-one dock format — vacuum, mop, and maintenance handled from one base station — paired with Alexa compatibility for voice control and smart dirt detection that adjusts cleaning behavior to what it finds on the floor.
The verdict
The Dreame X40 Ultra tackles a real friction point for busy families—a side brush that reaches corners other robot vacuums leave dirty, paired with mopping that actually cleans rather than just wetted floors—though at $540–$600 it's a significant investment for the convenience gain. Reviewers consistently praise its obstacle avoidance and pet-waste detection, which matter most in homes with animals.

AI summary of 5 reviews · as of Aug 2026
Reviewers largely agree this is one of the most capable robot vacuum-mop combos on the market, with strong suction, smart edge/corner reach, and a self-cleaning base, though at least one reviewer had a unit plagued by docking and navigation failures.
What they praise
- Strong, consistent suction on both carpets and hard floors
- Extending side brush and mop reach corners and edges other robots miss
- Self-cleaning base washes and dries mop pads with hot water and empties dust bin automatically
- Effective mopping, including on tough dried-on stains
- Automatically lifts mop pads and brushes to avoid wetting or tangling carpets
What they knock
- Long hair still tangles in the main brush unless the special anti-hair brush is fitted
- Complex app and many settings can feel overwhelming
- At least one unit repeatedly failed to dock and mount its mop pads correctly
- Premium build comes with a lot of components that can go wrong (sensors, mop attachment mechanism)

Dreame X40 Ultra Vacuum: do NOT buy this!
Louis Rossmann
How it holds up — after the dust settles
Both reviewers say the X40 Ultra keeps performing after months of daily use, with the base station's self-cleaning routines holding up and only minor upkeep needed.
Maintenance burden
At launch
Expected regular upkeep like emptying bins and cleaning hair from the brush, as with most robot vacuums.
After months
Found the auto-empty bag lasted months without swapping, and the anti-tangle brush design meant hair never had to be manually removed.
Mop pad hygiene
At launch
Worried hot water washing and drying claims might not hold up over time, with musty smells being common in mop-equipped robots.
After months
After months of use, no musty odors or mold appeared, and mop pads stayed clean through automatic hot water washing and drying.

Dreame is a mature brand with broad market presence and solid consensus; the X40 Ultra sits in an established product line with sufficient review depth.
You want a robot vacuum that works out of the box with minimal fuss.
Dual-function robot vacuums typically require app setup and mopping configuration; simpler single-function alternatives exist, but this model is reasonably straightforward.
You want a robot vacuum with mopping that won't break the bank.
Mid-range pricing with dual functionality covers basics well, but cheaper alternatives like the 360 Vis Nav deliver similar core performance at notably lower cost.

Frequently asked
What buyers want to know.
What makes the X40 Ultra different from other robot vacuums with mopping?
The side brush extends into corners and edges that fixed-arm robots typically miss, and the mopping actually cleans floors rather than just spreading water. Reviewers emphasize that the combination of these two features addresses a real gap in how most robot vacuums handle edges and wet cleaning.
Does it really avoid pet waste and obstacles?
Reviewers consistently praise its obstacle avoidance and pet-waste detection. The smart detection prevents the vacuum from smearing waste across your floors, which matters most in homes with animals.
Is the auto-empty station worth the investment?
The station handles washing, drying, and emptying automatically from one base. For busy families, reviewers note this frees up time on maintenance, though the overall cost sits at a significant investment for the convenience gain.
Who should buy this, and who might want to skip it?
It suits households that want an established brand's all-in-one dock format with mopping built in, plus voice control via Alexa. If you demand absolute top-tier performance regardless of price, premium rivals like Qrevo Curv and Freo Z Ultra offer deeper feature sets. If budget is tight, cheaper alternatives like the…
How much setup and fiddling is required?
