ComparisonDyson 360 Heurist and Roborock Q7 M5

Up to three

All robot vacuums. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.

Where each one suits you.

The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.

Fit verdicts by condition for each robot
Condition Dyson 360 Heurist Roborock Q7 M5
Home size
Under 1,500 sqft Good120 min runtime covers single-floor homes under 1,500 sqft; systematic camera-based mapping ensures no missed areas. GoodHomes & Gardens saw a 700 sq ft floor cleaned in about 65 minutes without running out of charge.
1,500 – 3,000they differ Depends120 min runtime may require 2 sessions for 1,500-3,000 sqft; multi-floor scheduling via app required. GoodVacuum Wars estimated about 1,370 sq ft per charge, and it recharges and resumes to finish.
Over 3,000they differ Poor120 min runtime insufficient for full-home coverage over 3,000 sqft in typical layouts. DependsThe 400 ml bin has no auto-empty, so homes this large may fill it before the run ends.
Primary floors
Hard floors GoodTrack drive provides stable traction on hard floors; no slip-out issues reported in owner forums. GoodVacuum Wars measured strong hard-floor pickup, though Homes & Gardens reported fine debris left on tiles.
Low / medium pile GoodCarpet transition handled by track drive; owner reports document reliable low-pile cleaning. GoodTom's Guide and TechRadar found it pulled dust and dog hair from low-pile carpet.
High pile / shag DependsSuction not documented in manufacturer specs; owner reports suggest adequate (not exceptional) high-pile cleaning. Tracks add weight for compression. DependsNo high-pile carpet test was found, and long hair tangled the roller in every review.
Mopping needs
Vacuum only GoodVacuum-only robot — matches a vacuum-only need. GoodVacuums first; the mop pad is optional.
Light moppingthey differ PoorThis model has no mopping function. GoodFlat mop pad handles light, routine wiping of hard floors.
Frequent moppingthey differ PoorNo mop at all; choose a vacuum-and-mop robot instead. DependsA dragged pad freshens floors but lacks the pressure or scrubbing for heavy, frequent mopping.
You want to…
Empty bin myself GoodNo self-empty dock or auto-wash; manual bin emptying and brush cleaning every 1-2 weeks. Track maintenance adds complexity. GoodOwners willing to empty the bin, wash mop cloths and cut hair from the roller will manage it.
Empty occasionallythey differ GoodWeekly brush and track inspection; monthly filter change. Track-specific wear requires occasional deep clean. DependsEvery run needs the bin emptied by hand, and mopping adds cloth washing and dampening.
Set-and-forget PoorManual emptying required after each session; track drive requires more maintenance than wheel-based robots. No auto-features available. PoorThe dock only charges, so bin emptying and mop care fall to you after every run.

A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
