Scores: Dyson 360 Vis Nav 7/10 · Roborock S8 MaxV Ultra 9/10
Roborock S8 MaxV Ultra wins for most homes. The fully automated dock — self-empty, mop-wash, and hot-air dry — removes the last manual maintenance steps that even premium robot vacuums leave to you. Dyson's 360 Vis Nav leads on carpet suction power, but the lack of mopping and 75-minute battery limit its real-world coverage. Unless you have deep carpet and zero hard floors, Roborock is the more...
Dyson 360 Vis Nav lists at $1,199 while Roborock S8 MaxV Ultra lists at $1,599 — Dyson 360 Vis Nav undercuts Roborock S8 MaxV Ultra by $400 (33%).

Dyson 360 Vis Nav
What works
- 26W suction is the highest measured input power in any robot vacuum — pulls carpet fiber debris that Roborock misses
- 360° vision with fisheye camera creates more accurate room maps in low-furniture rooms than LiDAR
- Square D-shape profile gets into corners that round robots leave unvaccuumed
What doesn't
- No mopping — the 360 Vis Nav is vacuum-only while Roborock S8 MaxV Ultra vacuums and mops
- 75-minute runtime is short for multi-room homes over 200 sqm — recharge cycles break sessions
- Camera navigation struggles in rooms with inadequate lighting or very dark floors
Roborock S8 MaxV Ultra
What works
- Dock auto-empties, washes mopping pads with warm water, and hot-air dries them — near-zero maintenance
- 180-minute runtime handles 300+ sqm in a single pass without recharging
- ReactiveAI 3D avoids dog waste, socks, and charger cables without mapping exclusion zones
What doesn't
- 10,000Pa suction is lower than Dyson's 26W rated input — on medium-pile carpet, Dyson picks up more
- $400 more than Dyson 360 Vis Nav — the dock technology carries a significant premium
- LiDAR sensor (20mm tall bump) prevents fitting under all sub-10cm furniture
Bottom line
Our pick: Roborock S8 MaxV Ultra.
