Edge-following accuracy is strong where reviewers saw the X40 actually reach into corners and edges well.

Emptying and mess control were mixed because the dock emptied debris but the process was described as noisy.

The dock's emptying and mess-control system is broadly convenient, although auto-empty suction is not universally perfect.

Wet-spill tests left floors dry enough that one reviewer found no visible dampness after cleaning.

The floorhead and hardware design were credited with helping the robot perform well as a vacuum.

The main roller/floorhead design is a rare weak point because hair pickup did not fully satisfy one tester.

The mop can leave floors shiny after routine cleaning.

Fresh liquid handling was a weak spot because one reviewer advised using the mop on dried stains rather than fresh spills.

Fresh wet spills were handled very well, with little sign left after the robot cleaned.

Hair-removal channel issues were present in one test where long hairs still tangled by the end of testing.

Hair can collect in a crevice near the wheelbase, though removal was manageable.

Carpet pet-hair pickup was above average in Vacuum Wars testing.

Carpet hair pickup is weak relative to the product's price, with only about half of test hair collected.

Hard-floor hair pickup was strong in the Trusted Reviews test, with complete pickup and no tangling.

General hair pickup is acceptable to good in some reviews, but it is not consistently excellent.

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.

Fine dust pickup on hard floors was generally strong, with several reviewers reporting excellent flour or fine-debris collection.

Hard-floor fine-debris pickup is consistently strong, with only minor misses in some tests.

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