A highly capable robot vacuum and mop that impresses most reviewers with its cleaning power, advanced base station, and corner-reach features, though one reviewer finds key features fall short in mixed-flooring households.
Owners love its powerful suction, smart mop-drop feature, and reliable daily performance, but struggle with low thresholds and step transitions that limit room access.
The Dreame X40 Ultra Complete delivers on its core promises of powerful suction, cordless convenience, and advanced reach technologies for corners and under furniture. However, the marketing overstates the real-world impact of its hot-water mopping upgrade and glosses over practical limitations: the side brush disables on carpets, the self-cleaning station still requires manual maintenance, and low thresholds prevent access to some rooms entirely.

About
What it is.
Dreame's X40 Ultra Complete sits in the robot vacuum family as a combined vacuum-and-mop system built around Vormax suction and extension mechanisms (SideReach, MopExtend RoboSwing) that let it work along walls and under furniture. It pairs with a multi-function base station that vacuums, mops, washes and dries its own mopping pads, and empties the dustbin, reducing manual upkeep between cleaning cycles. A HEPA filter, bagless bin, and Alexa compatibility round out its bagless, cordless design.
It's built for households with mostly hard flooring, particularly pet owners wanting an automated mop-and-vacuum routine with little daily intervention. Homes with wall-to-wall carpet or frequent rug-to-floor transitions are less suited to it, since the extending side brush and mopping functions lose relevance in those layouts.
The verdict
The Dreame X40 Ultra Complete ranks second among robot vacuums with mop and earns strong buyer approval (4.7/5) for its powerful suction and automated base station, though reviewers note its extendable side brush disables on carpet, making it best suited to hard-floor homes rather than mixed-flooring households.

AI summary of 5 reviews · as of Jun 2026
A highly capable robot vacuum and mop that impresses most reviewers with its cleaning power, advanced base station, and corner-reach features, though one reviewer finds key features fall short in mixed-flooring households.
What they praise
- Spinning mop pads with extend and swing technology clean corners, edges, and under furniture more thoroughly than most rivals
- Base station handles hot-water mop washing, hot-air drying, auto-emptying, and self-cleaning washboard with minimal user intervention
- 12,000 Pa suction delivers strong deep-clean performance on both hard floors and carpets, with automatic carpet-boost mode
- Tri-cut brush with built-in hair-shredding blades dramatically reduces hair tangles on the main roller
- Obstacle avoidance system scores near the top in controlled tests and navigates complex floor plans reliably
What they knock
- Extendable side brush deactivates on carpet and area rugs, leaving edges uncleaned in mixed-flooring homes
- Hot-water mopping improvement over the previous generation is marginal in real-world use, not the step-change advertised
- Base station accumulates grime over time despite its self-cleaning cycle; some manual maintenance is still needed
- Long hair can still tangle in the standard brush; the tri-cut brush is a separate accessory, not the default fitment for all units

What buyers say?
What Google knows about it.
Beyond the video critics, Google pools 3,205 buyer ratings of the X40 Ultra Complete from across retailers — a far wider, if blunter, jury. Here’s the shape of that opinion.

What owners single out
The one critical review flags inability to climb a 1-inch step into kitchen/bathroom, which aligns with video reviewers' concerns about physical obstacle navigation limitations.
In their words
“This is by far the best product I have used! It has the option of replacing the drum with tricut brush to cut the hair, so 0 hair will get tangled to the vacuum! Battery life is amazing, suction is perfect. It’s super smart & cleans 99% of the home, it has side brush & side mop which cleans all the edges & angles. It’s super smart & detects the dirtier areas & suggest it to you to go and clean it ”
Paul · verified purchase · dreametech.com
“Because there are small 1/4-inch bars in the hallway, and the robot can’t go over them. It also doesn’t climb the 1-inch step to get into the kitchen or bathroom. And it doesn’t automatically switch the roller when it reaches the carpet Also, I wrote two emails to your customer support service while my order was being delivered, and no one ever replied to my emails!!!”

Promise vs. proof.
We lifted Dreame’s headline product-page claims and checked each against what owners and expert reviewers actually report.
The Dreame X40 Ultra Complete delivers on its core promises of powerful suction, cordless convenience, and advanced reach technologies for corners and under furniture. However, the marketing overstates the real-world impact of its hot-water mopping upgrade and glosses over practical limitations: the side brush disables on carpets, the self-cleaning station still requires manual maintenance, and low thresholds prevent access to some rooms entirely.
“SideReach and MopExtend RoboSwing technologies reach under sofas, beds, and along walls”
Side brush deactivates on carpets
SideReach and MopExtend RoboSwing technologies do clean corners, edges, and under furniture effectively, but the extendable side brush deactivates on carpet and area rugs, leaving edges uncleaned in mixed-flooring homes.
“Because there are small 1/4-inch bars in the hallway, and the robot can’t go over them. It also doesn’t climb the 1-inch step to get into the kitchen or bathroom.”
OwnerDE G.H.
Suction Power“12,000Pa Vormax suction”Holds up
Multiple expert reviewers confirm the 12,000 Pa suction delivers strong deep-clean performance on both hard floors and carpets with automatic carpet-boost mode.
Self-Cleaning Station“7-in-1 self-cleaning station vacuums, mops, washes, dries, and empties itself”Mixed
The base station successfully handles hot-water mop washing, hot-air drying, auto-emptying, and self-cleaning, but accumulates grime over time despite its self-cleaning cycle and requires some manual maintenance.
Smart Cleaning“Smart dirt detection and automated mop care ensure every surface is fresh and clean”Mixed
Smart dirt detection and automated mop care work reliably for daily cleaning, but hot-water mopping improvement over the previous generation is marginal in real-world use, not the step-change advertised.
Cordless Design“Cordless: Yes”Holds up
Owner reviews confirm cordless operation with amazing battery life supporting daily usability.
“This is by far the best product I have used! It has the option of replacing the drum with tricut brush to cut the hair, so 0 hair will get tangled to the vacuum! Battery life is amazing, suction is perfect.”

You need a proven, low-risk robot vacuum with broad consensus and mature design.
3,205 ratings with 4.7/5 average, established brand, settled product line, and consistent reviewer praise signal a safe, well-tested choice with minimal surprise risk.
You demand top-tier cleaning performance and the most advanced features available.
Excels in suction, corner-reach mop tech, and obstacle avoidance with high buyer trust, but extendable brush disables on carpet and hot-water improvement is marginal—clear compromises for…
You want a capable robot vacuum and mop without overspending on premium brands.
Mid-range price (~$570–600) with strong 4.7/5 rating and advanced features (hot-water mop, auto-empty base) deliver solid value, though not the cheapest option available.
You want a robot vacuum that works out of the box with minimal setup or fiddling.
Base station automates most tasks (washing, drying, emptying), but requires ongoing manual maintenance, brush accessory swaps, and edge-case configuration—not truly set-and-forget.
You value prestige and flagship positioning from an established maker.
Dreame is tier-3 brand with solid reputation, but X40 Ultra is positioned as capable workhorse rather than luxury flagship—lacks the design prestige of true premium connoisseur picks.
You're excited by innovative design and sensory delight beyond raw specs.
Praised for engineering (spinning mop pads, tri-cut brush, obstacle avoidance) but reviewers focus on function and reliability, not aesthetic or emotional appeal—utilitarian rather than delightful. Consider Saros Z70.

Frequently asked
What buyers want to know.
What is the Dreame X40 Ultra Complete best at?
Reviewers say it excels at automated mopping and vacuuming with minimal daily work. The base station handles hot-water mop washing, drying, emptying, and self-cleaning. The spinning mop pads reach corners and edges better than most rivals, and the 12,000 Pa suction with automatic carpet-boost delivers strong cleaning…
Who is the Dreame X40 Ultra Complete for?
It is best for owners of predominantly hard-floor homes, especially those with pets, who want the most automated clean-and-mop routine with minimal daily intervention. It is not suited to households with wall-to-wall carpet or frequent transitions between area rugs and hard floors, because the extendable side brush di…
Does the side brush work on carpet?
No. The extendable side brush deactivates on carpet and area rugs, which is a significant limitation in mixed-flooring homes. Reviewers note this leaves edges uncleaned in those situations.
How much does the base station reduce daily maintenance?
Most reviewers say the self-cleaning cycle is genuinely hands-off after months of use. However, one reviewer observes the base station still accumulates grime over time and requires some manual cleaning despite the self-cleaning feature.
Is the hot-water mopping a major upgrade?
Reviewers are split. Several call the mopping and auto-adjust features a meaningful advancement, but one reviewer finds the hot-water mopping improvement over the previous generation is marginal in real-world use, not the significant step-change that was advertised.
How does it handle pet hair?
The tri-cut brush with built-in hair-shredding blades dramatically reduces hair tangles on the main roller compared to rivals. However, long hair can still tangle in the standard brush, and the tri-cut brush is a separate accessory, not the default fitment for all units.
