iRobot Roomba 105 Combo

Name: iRobot Roomba 105 Combo
Brand: iRobot
SKU: 18391

Manufacturer: iRobot

The iRobot Roomba 105 Combo is a robot vacuum cleaner designed to handle everyday floor cleaning with a reasonable degree of autonomy. It supports route mapping, allowing it to navigate systematically rather than at random, and can be scheduled and controlled remotely via a smartphone app. Voice assistant compatibility with both Google Assistant and Amazon Alexa adds further convenience for hands-free operation.

On the technical side, the unit runs for up to 120 minutes per charge on a 3000 mAh battery, with a full recharge taking around 4 hours and an operating power draw of 33W. It features HEPA and allergy filtration, a 0.6-litre dustbin, dirt detection, and anti-fall sensors, and covers all floor types across 4 cleaning modes. The robot also supports no-go zones and virtual barriers, weighs 2840 g, and connects via Wi-Fi 4 (802.11n).

Pros

Supports route mapping and no-go zones for organised, controlled cleaning across the home
Compatible with both Google Assistant and Amazon Alexa for hands-free voice control
Includes both a HEPA filter and an allergy filter, covering fine particle and allergen capture
Offers 120 minutes of runtime per charge, allowing extended cleaning sessions without interruption
Covers all floor types across 4 cleaning modes, adding flexibility for mixed-surface homes
Auto docking and scheduling allow the robot to operate with minimal manual intervention

Cons

Not self-emptying, requiring the dustbin to be manually emptied by the user
Does not include washable filters, meaning replacements are needed over time rather than simple rinsing
No fullness indicator, so there is no alert when the dustbin needs emptying
Lacks automatic height adjustment, which may affect performance on varying floor surface transitions
Charge time of 4 hours is relatively long relative to its 120-minute runtime
Does not include a physical remote control, limiting operation to smartphone or voice only

Who is this for?

This robot vacuum works well for households that want a largely hands-off cleaning routine, thanks to its scheduling, auto docking, and route mapping capabilities that allow it to operate on a set timetable with minimal user input. Its HEPA and allergy filtration make it a practical choice for people sensitive to dust and airborne particles, and its ability to clean all floor types across 4 modes suits homes with a mix of hard floors and carpeted areas. With 120 minutes of runtime and compatibility with both Google Assistant and Alexa, it fits naturally into a connected home setup where voice-controlled automation is already part of daily life.

Who is this NOT for?

Users who want a fully autonomous, low-maintenance setup may find this robot limiting, as it lacks a self-emptying function and does not indicate when the dustbin is full, requiring regular manual attention. Those with larger homes or complex floor plans may also be affected by the 4-hour charge time relative to its 120-minute runtime, which can interrupt cleaning coverage. Additionally, anyone looking for a combined wet-and-dry cleaning solution should note that despite the mopping specification, the robot offers no mop raising, drying, or dedicated mop management, which may limit its effectiveness on heavily soiled hard floors requiring more controlled wet cleaning.

The Roomba 105 Combo features a 0.6-litre dustbin, which offers a reasonable capacity for routine cleaning sessions. It does not have a display, nor does it include twin side brushes or washable filters — the included filters are not designed for rinsing and reuse. The robot does not automatically adjust its height to account for different floor surfaces, and there is no indicator to alert when the dustbin is full.

Final Verdict

The iRobot Roomba 105 Combo is a capable and well-rounded robot vacuum that covers the essentials of automated home cleaning with a degree of thoughtfulness — from its route mapping and scheduled operation to its dual filtration system that captures both dust and allergens. Its 120-minute runtime, all-floor-type compatibility, and voice assistant integration make it a genuinely practical option for connected households seeking a consistent, low-intervention cleaning routine. That said, the absence of self-emptying functionality and limited mop management mean it still demands a certain level of hands-on upkeep, keeping it more suited to users comfortable with periodic maintenance. On balance, the Roomba 105 Combo represents a solid mid-tier offering from iRobot for those who want reliable autonomous vacuuming without the full bells and whistles of a premium self-maintaining system.
