iRobot Roomba i3+ EVO specifications
The numbers that matter first, then every fact by group. As published by the maker or the store we read it from.
Consumables: a 2.5 l dust bag in the station, which lasts up to 60 days.
Dimensionsrobot and dock
From the published dimensions. The robot passes under furniture with 3.7 in of clearance or more. The dock needs a spot 12.2 in wide and 15.1 in deep.
Suction and brushes 3 facts
- Anti-tangle brush
A brush that guides hair to the side instead of letting it wind around the shaft. It saves the cutting work in homes with long hair or pets.
- yes
- Suitable for pet hair
Whether the robot copes with pet hair: a brush that hair does not wind around and a dock that empties the bin for you. Where the maker does not say so itself, we read it from those two.
- yes
- Dirt detection
A sensor notices where more dirt lies, at the doormat for example, and the robot cleans that patch longer or a second time.
- yes
Mopping 1 fact
- Mop type
How the mop is built: flat pads, two spinning discs or a roller. Discs press harder on dried-on dirt, a roller rinses itself while it works.
- no mop
Dock 5 facts
- Empties the dust bin
The dock empties the robot’s dust bin, usually after every run. You only empty the dock’s bag or bin.
- yes
- Bagless
The dock collects dust in a bin instead of a disposable bag. No bags to buy, but you empty it yourself.
- no
- Dust bag capacity
How much the dust bag in the dock holds.
- 2.5 l
- Dust bag lasts
How long the maker says a dust bag lasts with daily use. With pets or a lot of carpet it is shorter.
- up to 60 days
- Dock size (w × d × h)
The width, depth and height of the dock. Measure the spot you have in mind, and leave room for the lid and for the robot driving in.
- 12.2 × 15.1 × 19 in (31 × 38.4 × 48.3 cm)
Navigation and obstacles 3 facts
- Navigation
How the robot maps your home and follows that map. Lidar measures with a laser and works in the dark, a camera looks along and recognizes more.
- gyroscope
- Obstacle avoidance
How the robot sees loose things on the floor, such as cables, socks or a pet accident. A camera with depth sensing sees more than a bumper that reacts on contact.
- none
- Climbs thresholds up to
The highest threshold the robot takes, as the maker states it. Measure your own: the step into a bathroom or onto a balcony is often higher.

Robot 4 facts
- Robot height
How tall the robot is. It decides whether it fits under your sofa, bed or cabinet.

- 7.4 lb (3.37 kg)
- Dust bin in the robot
