The real decision
Both robots are built around the same promise: self-emptying without flagship pricing. That is the right feature to prioritize. A robot vacuum that empties itself is much easier to live with than a cheaper one you have to babysit after every run.
The difference is navigation and value. Roborock gives you LiDAR mapping and a more modern spec sheet. Roomba gives you a familiar ecosystem and good replacement-parts availability.
The shortlist
Roborock Q5 Pro+
The better value for most buyers: LiDAR mapping, self-emptying, 5500Pa suction, and DuoRoller brushes. It is the more modern robot at typical sale prices.
Strengths
- LiDAR mapping is more precise
- DuoRoller brush is strong for pet hair
- Better spec value
Tradeoffs
- No iRobot parts ecosystem
- No advanced obstacle camera
iRobot Roomba i3+ EVO
The safer Roomba ecosystem pick on sale. It self-empties, has straightforward app controls, and benefits from iRobot parts availability, but mapping is less precise than Roborock's LiDAR.
Strengths
- Simple Roomba ownership
- Good parts and service ecosystem
- Self-emptying at sale prices
Tradeoffs
- Less precise navigation
- No obstacle avoidance camera

Why the Roborock wins
LiDAR mapping is the deciding factor. It makes the robot feel less random and gives you a clearer map to manage rooms and routines. The Q5 Pro+ also has the stronger pet-hair value story because the DuoRoller design is built to keep hair moving into the bin instead of wrapping around a single brush.
When the Roomba still makes sense
Buy the Roomba i3+ EVO if the discount is strong and you value iRobot’s ecosystem more than specs. Roomba ownership is simple, parts are easy to find, and the app is approachable. It is not the more advanced robot; it is the familiar one.
The bottom line
At similar prices, buy the Roborock Q5 Pro+. The Roomba needs a real sale gap to win this comparison.

Frequently asked questions
Which is better, Roborock Q5 Pro+ or Roomba i3+ EVO?
Roborock Q5 Pro+ is better for most buyers because LiDAR mapping and stronger spec value matter every day. Roomba i3+ EVO makes sense if you specifically want iRobot's app, service path, and replacement parts ecosystem.
Which is better for pet hair?
Roborock Q5 Pro+ has the edge because its DuoRoller brush and stronger suction are better suited to hair on mixed floors. The Roomba is fine, but it is not the pet-hair value leader.
Which should I buy on sale?
If the prices are within $75, buy the Roborock Q5 Pro+. If the Roomba i3+ EVO is deeply discounted below the Roborock and you want simple ownership, it becomes reasonable.
