Spec, translated

The '36,000 Pa' suction figure likely represents theoretical motor performance under zero-load lab conditions, not the actual cleaning force delivered to your floor, making it a poor metric for comparison.

Lab notes

The observations that actually change the buying decision.

The 36,000 Pa suction claim is not physically credible for a battery-powered robot; it is likely a useless, non-standard measurement taken at the motor itself.

A claimed 3.46-inch (88mm) climbing height on a 3.14-inch (80mm) tall robot defies physics. This is a severe red flag indicating either a typo or dishonest marketing.

The combination of 3D Time-of-Flight sensors and an RGB camera for navigation is a genuinely high-end system and likely the robot's most competent feature.

At $1600, this product is priced to compete with the most established flagships, yet it enters the market with specifications that undermine its own credibility.

Why you should buy

This is for early adopters with a very large budget who trust the Roborock brand name over its spec sheet. Its slim profile is a genuine benefit for getting under low furniture, and the navigation hardware is proven technology.

Why you should skip

Anyone for whom $1600 is a significant investment should avoid this model. The unbelievable performance claims are serious red flags, and established alternatives from Roborock and its competitors offer similar core features for less money with more transparent data.
