JONR X9 Pro vs. Roborock S8 MaxV Ultra
The Roborock is still the more complete robot: dual rubber rollers, the strongest carpet reputation in independent testing and the deepest app. The JONR X9 Pro answers with continuous fresh-water roller washing, 20,000 Pa claimed suction and a 167°F hot-wash dock for less than half the price — the pick for hard-floor-first homes on a budget.

The Quick Verdict
The Roborock is still the more complete robot: dual rubber rollers, the strongest carpet reputation in independent testing and the deepest app. The JONR X9 Pro answers with continuous fresh-water roller washing, 20,000 Pa claimed suction and a 167°F hot-wash dock for less than half the price — the pick for hard-floor-first homes on a budget.
Winner: Roborock S8 MaxV Ultra
For carpet-heavy homes, the S8 MaxV Ultra is the robot to beat: the top carpet score in our database, a strong mapping reputation and the most mature software. Its only real competition is on price, where the JONR X9 Pro gets uncomfortably close on features for under half the cost.
Runner Up: JONR X9 Pro Robot Vacuum & Mop
The JONR X9 Pro represents a major architectural shift in robot floor care, replacing traditional passive dragged mop pads with an active, continuous fresh-water roller wash system. Paired with 20,000Pa claimed motor suction, an automated docking station that cleans at 167°F (75°C) and hot-air dries, and mechanical Dual Flex Arms for 90° edge coverage, it delivers flagship-tier automated maintenance at the $599 price JONR's official store currently lists. For households with sealed hardwoods, tile, and active pets, it is our Editor's Choice for automated mopping.
- You want continuous fresh-water roller mopping instead of dragging a damp cloth pad across rooms
- You need a fully automated thermal dock that washes at 167°F (75°C) and hot-air dries to prevent odors
- You have deep-pile carpets requiring 10,000 Pa suction and dual counter-rotating rubber rollers
- You want complete hands-off autonomy with extending side brush and mop baseboards
Our Takeaway: Roborock S8 MaxV Ultra earns our overall recommendation (9.4/10 vs 8.7/10) for 20,000pa fresh-water wash vs. the $1,299 flagship, while JONR X9 Pro remains a viable choice if saving $700 is your top priority.

The Case For & Against
JONR X9 Pro
The Case For It
- +Fresh-water continuous mopping prevents cross-contamination with active roller squeegee
- +Massive 20,000Pa claimed suction power with auto carpet boost
- +Excellent dock automation: 167°F hot-water wash & warm air dry
- +Dual Flex Arms effectively cover 90° edges and tight corners
- +Strong value at the $599 price JONR's official store currently lists (list price $1,499)
The Case Against
- –All-in-one docking station requires dedicated floor footprint (18" x 14" x 17")
- –Overkill for homes that are primarily high-pile carpet and do not need advanced mopping
- –LiDAR turret does not retract, requiring at least 4.33 inches under-furniture clearance
- –The $599 price was on jonrofficial.com on 2026-10-19; JONR's other storefront, jonrtech.com, lists $1,499 and shows it sold out
Roborock S8 MaxV Ultra
The Case For It
- +10,000 Pa rated suction and dual rubber rollers for deep carpet
- +FlexiArm side brush and extending mop reach right into corners
- +Best-in-class app with remote video, voice assistant and Matter
- +Dock also refills the robot's water tank and dispenses detergent
- +Independently measured 93.9% debris removal on high-pile carpet and 99.8% on hardwood
The Case Against
- –Street price is still around $1,300
- –Mop pads spin rather than scrub, so dried stains take multiple passes
- –Dock is large (48 cm tall) and needs a 5 cm clearance each side
- –The onboard voice assistant and auto-extending side brush have been reported unreliable in independent testing
- –Struggles with fine granular debris (sugar, litter) worked into carpet fibers
