What reviewers say

iRobot Roomba j7+

  • 3.8 / 5526 ratings

Ratings average 3.8 out of 5 from 526 buyers, a middling score for a premium robot vacuum. Owners tend to like the self-empty base and the object avoidance, while complaints cluster around navigation quirks and reliability over time.

What people mention
  • Self-empty basePraisedOwners say the Clean Base lets them go weeks without touching the bin.
  • Obstacle avoidancePraisedReviewers report it reliably steers around pet waste, cords and shoes.

  • ReliabilityCriticisedA share of buyers report failures or degraded cleaning after a year or more.

ECOVACS DEEBOT T90 PRO OMNI

  • 4.8 / 5808 ratings

Owners rate the T90 PRO OMNI highly, with 808 ratings averaging 4.8 out of 5. They tend to praise the hands-off base station and the combined vacuum-and-mop routine. Some note the base is bulky and that mop upkeep doesn't disappear entirely.

What people mention
  • Self-emptying basePraisedOwners like that the OMNI station empties the dustbin so they go weeks without touching it.
  • MoppingPraisedReviewers say the mop leaves hard floors noticeably cleaner, especially in kitchens.
  • Base sizeCriticisedThe 31 lb base is bulky and needs a dedicated spot with clearance.
  • NoiseMixed

Questions and answers

Which is better for pet hair?
Both handle pet hair. The j7+ has rubber brushes and a camera that avoids pet waste, backed by iRobot's replacement promise. The T90 PRO OMNI has stronger suction on paper but no such guarantee.
Do I need the mopping on the T90 PRO OMNI?
Only if you have hard floors. On carpet the mop adds little, and the j7+ at $119.99 is the smarter buy.
Is the T90 PRO OMNI worth the extra money?
Yes if you want mopping and a dock that washes the mop. If you only need vacuuming, the j7+ saves you about $330.
Which is easier to set up and move?
The j7+ weighs 7 lb and is easy to carry. The T90 PRO OMNI weighs 31 lb, mostly the dock, so plan where it lives.
Which has better obstacle avoidance?
The j7+. Its PrecisionVision camera is built to dodge cords, socks and pet waste, which is the j7+'s main selling point.
How often do I have to touch each one?
The j7+ empties itself into bags for months but you still refill nothing else. The T90 PRO OMNI also washes and refills its mop water, so you handle it less often.
