Small-space suitability is limited by the large dock, even though the robot itself navigates well.

Obstacle avoidance was one of the more mixed areas, ranging from best-in-brand results to missed cords, pet mess, or low obstacles.

Obstacle avoidance is a standout, with multiple reviewers praising AI recognition, pet-accident avoidance, and reliable object navigation.

Value-for-money was positive within the premium category, though still tied to the high purchase price.

Value is mixed-to-positive: costly upfront, but reviewers often found the automation and feature set worth it.

Hair-wrap resistance was usually strong, though one review still found some long hairs tangled in parts of the brush system.

Hair-wrap resistance is mixed: standard brushes can tangle, but anti-tangle design and optional accessories reduce maintenance.

Controls and UI were useful overall, especially voice control, but some app controls and no-mop-zone limitations made the experience less simple.

Controls and UI are feature-rich and highly customizable, but the app can feel clunky in places.

Mopping performance was generally good to excellent for maintenance and many stains, but tougher messes sometimes required extra passes.

Mopping performance is one of the X40's strongest areas, with repeated praise for rotating pads, tough stains, and overall results.

Surface safety evidence was positive where mop lifting kept rugs dry during combined vacuuming and mopping.

Surface safety is good around wet spots and carpet/rug protection because the robot avoids spreading liquid or damp pads.

The dirty-water sensing and remopping features were praised as useful when mop pads came back especially dirty.

Dirty-water sensing is praised as a useful advanced base-station feature that can trigger additional cleaning.

Odor control evidence was positive where the hot-air drying cycle was described as preventing mop-pad odors.

Odor control is strong because hot washing and drying help prevent musty mop-pad smells.

Comparative performance was favorable overall, including high rankings and direct reviewer comparisons against other premium robots.

Comparative evidence is mostly favorable, with X40 outperforming older Dreame models and ranking near the top, though one suction claim was viewed skeptically.

Large debris intake on hard floors was mostly good but not flawless, especially when oats were scattered by the side brush.

Large hard-floor debris intake is strong overall, despite occasional missed cereal pieces.

Dried-on stain removal was usually strong, especially with two passes or dedicated deep mopping modes.

Dried-on stain removal is repeatedly praised, especially for coffee, grape juice, and sticky messes.

Versatility was positive because reviewers highlighted adjustable modes, customizable cleaning parameters, and combined vacuum-mop operation.

Versatility is high across hard floors, carpets, rugs, mopping, vacuuming, pet features, and customized room cleaning.

Reviewers generally found real-world suction and pickup strong, though bench airflow or raw power measurements were not always top-tier.

Suction and airflow are consistently praised as powerful, high-performing, and above average, though one setting limitation was noted.

Under-furniture pickup was one of the clearest strengths because the low body reached areas taller robots could not.

Under-furniture pickup is strong where the side brush and mop reach under appliances and low furniture edges.

Area rug handling was a standout strength in TechRadar's testing, especially for thick rugs and raised thresholds.

Carpet and rug handling is a strength because the X40 can lift or leave mop pads behind to reduce wet-carpet risk.

Innovation was a standout theme because the low-profile StarSight/ToF navigation was repeatedly described as new, effective, and competitive.
