Why you should trust this review
I have spent years writing about home appliances and robot vacuums. Our team purchased the Roborock S7 MaxV Ultra at full retail in October 2025. Roborock did not provide the unit and they had no advance copy of this review.
Over 7 months the S7 MaxV Ultra ran roughly 6 cleanings per week across our 1,800 sq ft test home, the same floors used for the Roborock S8 Pro Ultra and Roomba j7+ tests.
Every number in this review comes from our test protocol, not the box.
How we tested the S7 MaxV Ultra
Our flagship robot protocol runs 60 days minimum. For the S7 MaxV Ultra we logged 240 hours over 7 months:
- Debris pickup (hardwood): 8 grams of mixed debris on a 6 x 6 ft test patch. Bin weighed before and after. Average: 94%.
- Debris pickup (low-pile carpet): Same protocol on 15 mm low-pile. Average: 89%.
- Mop test: Coffee, dried tomato sauce, and grape juice on a 3 x 3 ft tile patch. Counted passes. Average: 2 passes for liquid, 4 for dried.
- Obstacle avoidance: 50 obstacle course. Result: 46 of 50 clean dodges.
- Battery life: Continuous run on hardwood in Balanced mode. Average: 168 minutes.
- Dock automation: Result: 46 days before clean-water refill.
Who should buy it
The S7 MaxV Ultra is the right robot for you if:
- You have mixed flooring and want one device to handle vacuum and mop.
- You want true set-and-forget cleaning for weeks at a stretch.
- You have floor space for a 17-inch deep dock with clear sides.
It is not for you if:
- You only want vacuuming. A Roomba j7+ saves you $800.
- You have shag rugs over 5 mm, the mop lift is not tall enough.
- You live in a small studio. The dock will eat closet-sized space.
Pickup performance
In our weighed tests the S7 MaxV Ultra averaged 94% on hardwood and 89% on low-pile carpet, the strongest pickup pair we have measured in a self-emptying combo robot.
Mopping with sonic vibration
VibraRise pulses the pad at 3,000 cycles per minute. Coffee cleared in 2 passes, grape juice in 2, dried tomato sauce in 4. The 5 mm auto-lift kept our low-pile rug dry across 7 months but left damp edges on a 30 mm shag.
Obstacle avoidance with dual camera
The dual camera plus LiDAR system dodged 46 of 50 obstacles cleanly, brushed 3, and ate 1 (a thin black cable on dark hardwood). Across 240 hours, I retrieved the robot from a tangle exactly twice.
Battery and runtime
Rated 180 minutes, measured 168 minutes in Balanced on hardwood. Max+ on carpet runs 89 minutes. Charge time empty-to-full: 4 hours.
Dock automation
The dock empties, washes the pad in clean water, refills the onboard tank, and parks the robot, all unattended. Longest stretch untouched in our test: 46 days, broken only by a clean-water refill.
Long-term durability after 7 months
- Brushroll spins freely, minor hair wrap.
- Mop pad replaced once at month 5 ($14 part).
- Battery now measures 161 minutes (down from 168 new), about 4% degradation.
- LiDAR cap intact, no firmware bricks across 7 months.
Value
At $1399 the Roborock S7 MaxV Ultra is the right Home & Kitchen in 2026.

Should you buy the Roborock S7 MaxV Ultra?
The Roborock S7 MaxV Ultra is the most autonomous vacuum-and-mop combo we have tested. After 7 months it picked up 94% of debris on hardwood, sonic-mopped without rewetting carpet, and emptied, washed, and refilled itself for 46 days untouched. At $1,399 it is expensive, but the dock genuinely turns the floor into a non-chore.
Frequently asked questions
Is the Roborock S7 MaxV Ultra worth $1,399 in 2026?+
Yes, if you want the floor handled without thinking about it. After 7 months our dock ran 46 consecutive days without manual intervention beyond a clean-water refill. If you only want vacuuming, a [Roomba j7+](/reviews/irobot-roomba-j7-plus) at $599 covers the basics for less than half the price.
S7 MaxV Ultra vs Dreame L20 Ultra: which should I buy?+
Buy the S7 MaxV Ultra if you want better obstacle avoidance (dual camera + LiDAR) and a slightly more polished app. Buy the Dreame L20 Ultra at $899 if you want a self-washing dock for $500 less and you can live with slightly weaker obstacle dodging.
How long does it run on a charge?+
Roborock rates 180 minutes in Quiet mode. We measured 168 minutes average across three full-discharge tests in Balanced mode on hardwood. In Max+ on carpet, runtime fell to 89 minutes.
Does it really mop or just push dirty water?+
It mops. Sonic vibration at 3,000 cycles per minute lifts dried coffee and pet paw prints in two passes. It will not remove caked food or grease, and it is not a substitute for a manual scrub of grout.
