iRobot Roomba Combo J7+ specifications
The numbers that matter first, then every fact by group. As published by the maker or the shop we read it from.
iRobot · on the market since June 2023
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 9 cm of clearance or more. The dock needs a spot 40 cm wide and 30 cm deep.
Mopping 2 facts
- 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.
- flat or vibrating pad
- Mop lift on carpet
How far the robot lifts the mop when it drives onto a carpet. From about 10 mm a medium pile stays dry.
- 30 mm
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.
- 39.9 × 30.2 × 33.8 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 recognises more.
- camera
- 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.
- AI camera
- 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.
- 16 mm
- Climbing system for high thresholds
An extending leg or wheel that carries the robot over a high threshold. Without one it usually stops at about 2 cm.
- no
Robot 3 facts
- Robot height
How tall the robot is. It decides whether it fits under your sofa, bed or cabinet.
- 8.6 cm
- Robot diameter
How wide the robot is. Narrower gets between chair legs more easily, wider usually means a bigger dust bin.
- 33.8 cm
- Dust bin in the robot
How much dust the robot holds before you empty it. It matters less with an auto-empty dock, which empties the bin after every run.
- 250 ml
Battery 2 facts
- Battery capacity
The capacity of the battery. It hints at the runtime, but how much the robot draws counts just as much.
- 4,460 mAh
- 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.
- 75 min
Smart features and warranty 2 facts
- Voice assistants
Which voice assistants the robot works with, such as Google Assistant or Alexa.
- Alexa, Google Assistant
- Warranty
The warranty the maker gives in the Netherlands. Consumer law here stands apart from it and can last longer.
- 2 years
