What reviewers say

Roborock Q7 Max

Owners of the Q7 Max generally rate it well for suction and mapping at its price. Common complaints are the lack of a self-emptying dock and the basic mop.

Pros
  • Reliable LiDAR mapping and room-by-room cleaning
  • Good pickup of pet hair on hard floors and low-pile carpet
  • Rubber brush needs little hair detangling
  • App scheduling and no-go zones work well
Cons
  • Mop is light-duty and does not scrub
  • Bin fills quickly in large or hairy homes
  • Can struggle on thick carpet and high thresholds
  • Setup requires 2.4GHz Wi-Fi

iRobot Roomba Combo j7+

Owners generally like the j7+ as a vacuum and value the mop pad that lifts away on carpet, but many call the mopping light-duty and note the camera-based navigation can struggle in cluttered or dim rooms.

Pros
  • Reliable vacuuming on carpet and hard floors
  • Mop pad lifting over carpet works as advertised
  • Self-emptying base cuts down on emptying
  • Good at picking up pet hair
Cons
  • Mopping is shallow, more a wipe than a scrub
  • Navigation can miss spots in cluttered or dark rooms
  • Base is bulky
  • Premium price for the mopping it delivers

Questions and answers

Which is better for pet hair?
Both target pet hair. The Roborock's 4,200Pa suction and rubber brush give it an edge on raw pickup, while the Roomba's self-emptying base means less frequent bin emptying in a hairy home.
Is the Roomba Combo j7+ worth the extra money?
Only if self-emptying and the retracting mop matter to you. At $411.99 versus $224.99 as of November 5, 2026, you pay about $187 for convenience, not cleaning power.
Which cleans carpet better?
The Roborock has higher rated suction and a rubber brush that digs into carpet. The Roomba's advantage on carpet is its mop lifting clear, so it can vacuum and mop in one run without wetting the rug.
Which has better navigation?
The Roborock. LiDAR mapping builds a precise floor plan and plans efficient routes. The Roomba uses camera navigation, which works but is generally less exact in the dark.
How long does each run on a charge?
The Roborock runs up to 180 minutes; the Roomba Combo j7+ runs about 90 minutes and recharges in roughly 3 hours.
Do either need Wi-Fi?
Yes for app features. The Roborock supports 2.4GHz Wi-Fi only, so a 5GHz-only network will not connect. The Roomba also pairs with Google Assistant and Alexa.
