iRobot Roomba i4+ EVO specifications

The numbers that matter first, then every fact by group. As published by the maker or the store we read it from.

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 4 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.

0.6 in (16 mm)
No-go zones

How you keep the robot out of a place: a zone you draw in the app, a virtual wall or a magnetic strip on the floor.

virtual walls
Robot 4 facts
Robot height

How tall the robot is. It decides whether it fits under your sofa, bed or cabinet.

3.6 in (9.2 cm)
Robot diameter

How wide the robot is. Narrower gets between chair legs more easily, wider usually means a bigger dust bin.

13.3 in (33.7 cm)
Robot weight

What the robot weighs. It counts most if you carry it up a staircase every day.

7.4 lb (3.37 kg)
Dust bin in the robot

How much dust the robot holds before you empty it. It matters less with a self-emptying dock, which empties the bin after every run.

500 ml
Battery 1 fact
Runtime per charge

How long the robot cleans on one charge, at its quietest setting. After that it recharges and carries on where it stopped.

90 min
Smart features and warranty 3 facts
Voice assistants

Which voice assistants the robot works with, such as Google Assistant or Alexa.

Alexa, Google Assistant, Siri
Scheduled runs

You set days and times, and the robot starts by itself, also when you are not at home.

yes
Home Assistant

Whether the robot works with Home Assistant, the home automation software you run yourself. Official means the integration comes with Home Assistant itself, community that volunteers maintain it.
