The catch
The base station requires a separate, paid module to activate its automatic cleaning solution dispenser, a key function that isn't included in the box.

Spec, translated

The 'extendable side brush and mop' means the robot can physically reach into corners and along baseboards, areas most circular robots miss, providing a more complete clean.

Lab notes
The observations that actually change the buying decision.
01
The 25,000Pa suction figure is a theoretical maximum, not a reflection of sustained, real-world cleaning power at the brush head.
02
The extendable brush and mop address the common weakness of poor edge cleaning, but add mechanical complexity and a potential future point of failure.
03
The base station's automatic cleaning solution function is neutered out of the box; the necessary dispenser module is a separate purchase.
04
A 5,200mAh battery is adequate, but the 231-minute runtime claim applies only to 'Quiet Mode', not typical mixed-surface cleaning at higher power.

Why you should buy

This is for the value-conscious buyer who wants top-tier features like an all-in-one dock and advanced obstacle avoidance without paying a premium. If you prioritize edge cleaning and are willing to take a chance on a newer model, the price-to-performance ratio is compelling.

Why you should skip

Those who prioritize proven reliability and a seamless out-of-box experience should look elsewhere. Buyers who dislike products with key features locked behind a separate, post-purchase accessory upgrade will be justifiably annoyed.
