Ecovacs Deebot X9 Pro Omni vs iRobot Roomba Max 775 Combo

The Deebot X9 Pro Omni is the stronger vacuum: 16,600 Pa suction, a wider air inlet and a 200-minute battery make it the better pick for heavy pet hair and large carpeted homes. The Roomba Max 775 Combo is the tidier mopping system, with a roller mop cover that lifts to keep rugs dry and a heated self-washing mop. Both dock themselves, but the Deebot's OMNI Station empties the bin for up to 90 days while the Roomba's AutoWash Dock runs about 3 months. Owners rate the Roomba slightly higher, though the Deebot's higher suction and longer runtime win on raw cleaning power.

  • Choose the Deebot X9 Pro Omni if you have wall-to-wall carpet, shedding pets and want maximum suction and runtime.
  • Choose the Roomba Max 775 Combo if you have a mix of rugs and hard floors and want a mop that stays off the carpet.

What reviewers say

Ecovacs Deebot X9 Pro Omni

  • 4 / 537 ratings

Rated 4 out of 5 from 37 ratings. Owners largely praise the suction on pet hair and the hands-free station, while some flag noise and the size of the dock.

What people mention
  • SuctionPraisedOwners say the 16,600Pa BLAST system pulls up pet hair and larger debris from carpets and hard floors.
  • Mop cleaningPraisedThe roller rinses itself with fresh water during cleaning, and the station hot-washes and dries it afterward.
  • NoiseCriticisedHigher motor wattage makes it louder than quieter robots, especially on max suction.
  • SizeMixedThe 28 lb robot and the OMNI station are bulky and need dedicated floor space.

iRobot Roomba Max 775 Combo

  • 4.2 / 540 ratings

Ratings average 4.2 out of 5 from 40 buyers, with most praise going to the self-washing mop and hands-off dock. Complaints center on the price, the small bin and occasional navigation quirks.

What people mention
  • Mop washingPraisedOwners like that the dock washes and dries the roller so it doesn't sit wet and smelly.
  • Pet hairPraisedRubber brushes and strong suction pick up shedding hair without tangling.
  • Dust binCriticisedThe 0.01 gal onboard bin fills fast, so the dock runs often.
  • NavigationMixed

Questions and answers

Which is better for homes with mostly carpet?
The Deebot X9 Pro Omni. Its 16,600 Pa suction and Triple Lift system are built for deep carpet cleaning, and its 200-minute runtime covers more floor per charge.
Which keeps rugs drier while mopping?
The Roomba Max 775 Combo. Its roller mop cover lifts and shields the mop, which is a more deliberate carpet guard than the Deebot's lift system.
Which lasts longer per charge?
The Deebot, rated at up to 200 minutes. iRobot does not publish a comparable runtime for the Max 775 Combo.
Is the Deebot worth stepping up to over the Roomba?
If suction and runtime matter most, yes. If you want the tidier mop and broader voice support, the Roomba is the better fit.
Do both docks wash and dry the mop?
Yes. The Deebot hot-washes at up to 167°F and dries at up to 145°F; the Roomba washes at 167°F and dries at 122°F.
Which works with more smart home systems?
The Roomba supports Google Assistant, Alexa and Siri. The Deebot supports Google Assistant and Matter.
