Q Revo MaxV vs S8 MaxV Ultra — which should I buy?

If your home is mostly hard floors with some low-pile carpet, save the money and get the Q Revo MaxV. If you have lots of thick carpet, multiple large dogs, or just want the absolute best, the S8 MaxV Ultra's stronger suction and dual rubber brushes justify the premium.

How is the mopping compared to dedicated mop robots?

It's described as very good for a combo unit — the dual spinning pads apply decent pressure and handle daily dirt well. It won't match a Narwal or Braava for serious mopping, but for maintenance cleaning between manual mops, most owners are satisfied.

Does the mop lift work well enough for carpet?

It works for low-pile carpet but some owners report slight dampness at carpet-to-hard-floor transitions. If you have a lot of high-pile carpet, consider getting additional dry mop pads or just removing the mop attachment for carpet-heavy runs.

How's the noise level?

Quiet mode is genuinely quiet — can run while watching TV. Max mode is noticeable but not disruptive. Most owners run it on balanced mode during the day and quiet mode at night.

Is it good for pet owners?

Yes, it's one of the most recommended for pet owners in the mid-range. The obstacle avoidance helps avoid pet toys, and the hot water mop washing handles pet-related floor messes well. Just note the brush tangles with long pet hair more than the S8 MaxV's dual rubber system.

Roborock Q Revo MaxV

Name: Roborock Q Revo MaxV
Brand: Roborock
Price: 700 USD
Availability: Discontinued

This is the Roborock that makes the flagship feel overpriced for most homes — you get roughly 90% of the S8 MaxV Ultra experience for significantly less. The dual spinning mop pads press harder than vibrating-plate systems and clean dried spots better, the hot water dock keeps the pads fresh without you touching them, and 7000Pa suction handles daily pet hair on hard floors and low-pile carpet with ease. Obstacle avoidance reliably dodges cables, shoes, and pet toys, and the app's per-room customization is best-in-class. Where it falls short of the flagship is thick carpet, where the suction gap becomes noticeable, and the bristle-plus-rubber combo brush tangles with long hair more than dual rubber rollers do. The dock is nearly flagship-sized too, so measure your space first. For a typical 1500-2500 sq ft home with mixed floors and a pet or two, owners call this the sweet spot in Roborock's lineup.

Owner Insights

The Q Revo MaxV is consistently recommended in robot-vacuum owner discussions as the sweet spot in Roborock's lineup. It comes up constantly in "best robot vacuum under $1200" threads, with owners praising it as the model that makes the S8 MaxV Ultra feel overpriced for most homes. The dual spinning mop pads are frequently highlighted as a meaningful upgrade over Roborock's older vibrarise mopping.

Real-world vacuuming reviews are positive — 7000Pa handles daily pet hair and general debris on hard floors with ease. The obstacle avoidance, while not quite as refined as the S8 MaxV, reliably dodges most common floor obstacles. Where it falls short vs the flagship is on thick carpet, where the suction difference becomes noticeable. The bristle+rubber combo brush also gets more complaints about hair tangling than the S8 MaxV's dual rubber system.

Most owners position it as the best buy for typical households — those with mixed hard floors and low-pile carpet, 1-2 pets, and 1500-2500 sq ft homes. If you have lots of thick carpet or need maximum suction, the S8 MaxV is worth the upgrade. For everyone else, the Q Revo MaxV delivers premium performance at a much more palatable price point.

Pros

+Best value all-in-one robot — gets you 90% of the S8 MaxV Ultra experience for significantly less
