iRobot Roomba Combo Essential

Manufacturer: iRobot

The iRobot Roomba Combo Essential is a robot vacuum cleaner that handles both vacuuming and mopping across all floor types, offering a straightforward two-in-one cleaning approach without requiring manual intervention between tasks. It features HEPA and allergy filtration, making it a practical option for households where airborne particles are a concern. The unit supports Wi-Fi connectivity, can be controlled via smartphone, and works with both Google Assistant and Alexa for voice-based operation.

On the feature side, the Roomba Combo Essential includes auto docking, scheduled cleaning, virtual barriers, anti-fall and obstacle sensors, anti-stuck behaviour, voice prompts, and water level adjustment for its mopping function, though it does not support mapping, no-go zones, or route planning. The 1800 mAh battery delivers up to 75 minutes of runtime and recharges in around 2 hours, with an operating power draw of 33W and an auto-off function to conserve energy. The dustbin holds 0.4 litres, the unit operates at 61 dB, and it measures 330 mm in diameter and 80 mm in height, with a total weight of approximately 2799 g. A one-year warranty is included.

Pros
  • Both HEPA and allergy filters are included, making the unit suitable for dust-sensitive households
  • Combines vacuuming and mopping across all floor types, handling two cleaning tasks in a single pass
  • A dirt sensor allows the robot to detect and concentrate on heavily soiled areas automatically
  • Virtual barriers let users confine cleaning to specific areas without physical accessories
  • Auto docking ensures the robot returns to its base independently at the end of a session or when the battery is low
  • Compatible with Google Assistant and Alexa, enabling hands-free voice control
Cons
  • The 0.4-litre dustbin is relatively small and provides no full indicator, requiring users to check and empty it manually
  • Mapping, route mapping, and no-go zones are all absent, limiting control over where and how the robot cleans
  • The unit is not self-emptying, so the dustbin must be emptied by hand after each or multiple cleaning sessions
  • Filters are not washable, meaning they need to be replaced rather than rinsed and reused
  • The 75-minute runtime may not be sufficient for larger homes in a single charge cycle
  • Mop automation features such as mop raising, mop cleaning, and mop drying are not supported
Who is this for?

The iRobot Roomba Combo Essential is well suited to users with small to medium-sized homes who want a straightforward robot that handles both vacuuming and mopping without requiring complex setup or app-based floor planning. The inclusion of HEPA and allergy filtration makes it a practical fit for allergy-prone households where airborne dust and particles are a concern. Users who appreciate convenience features such as auto docking, scheduled cleaning, and voice control via Google Assistant or Alexa will find the feature set covers everyday automation needs adequately, particularly on mixed floor surfaces where all-floor-type compatibility is relevant.

Who is this NOT for?

Users with larger homes are likely to find the 75-minute runtime insufficient to complete a full clean in a single cycle, and the absence of mapping and route planning means the robot cannot be directed to prioritise specific rooms or return to where it left off intelligently. Those who want a more hands-off maintenance experience will be disappointed by the lack of self-emptying capability and the absence of a full-bin indicator, as the 0.4-litre dustbin requires frequent manual attention with no prompting from the unit. Households that need advanced mopping automation — including mop raising over hard floors, mop drying, or automated mop pad cleaning — will also find the mopping implementation too basic for those requirements.

The Roomba Combo Essential supports Wi-Fi connectivity and smartphone remote control, along with scheduled cleaning and voice prompts for basic operational feedback. Navigation is assisted by obstacle and anti-fall sensors, and the unit includes anti-stuck behaviour and virtual barriers to define cleaning boundaries, though mapping, route mapping, and no-go zones are not supported. Auto docking is present, so the robot returns to its base independently when finished or low on battery, but it is not self-emptying and does not include a physical remote control. Water level adjustment is available for the mopping function, while mop cleaning automation, mop raising, and mop drying are all absent.

Design:

Has a display ✕
has twin side brushes ✕
has included washable filters ✕
automatically adjusts its height ✕
Indicates when full ✕

The unit features a 0.4-litre dustbin that does not indicate when full, meaning it requires manual monitoring to avoid overfilling. There is no display on the device, no twin side brushes, and the filters included are not washable. The robot also does not automatically adjust its height to account for different floor surfaces or carpet thicknesses.

Cleaning power:

cleans all floor types ✓
cleaning modes 2
mops ✓
has a dirt sensor ✓
has UV light ✕

The Roomba Combo Essential is capable of cleaning all floor types and includes a mopping function alongside standard vacuuming, giving it two cleaning modes in total. A dirt sensor helps the unit detect and respond to areas requiring more attention, while UV light is not included.

Power:

battery power 1800 mAh
runtime 75 min
charge time 2 hours
operating power consumption 33W
has auto-off ✓

The Roomba Combo Essential runs on a 1800 mAh battery that delivers up to 75 minutes of cleaning per charge, with a full recharge taking approximately 2 hours. Operating power consumption is rated at 33W, and an auto-off function is included to cut power automatically when the unit is not in use.

Final Verdict

The iRobot Roomba Combo Essential is a no-frills robot vacuum cleaner that covers the fundamentals well — combining vacuuming and mopping across all floor types with HEPA and allergy filtration, auto docking, scheduled operation, and voice assistant compatibility in a compact, easy-to-use package. It suits smaller homes where its 75-minute runtime is adequate and where straightforward daily automation is the primary goal rather than precision room-by-room control. The absence of mapping, self-emptying, and a full-bin indicator does place real limits on how hands-off the experience can be, and the dustbin will need regular manual attention. For users who want a reliable, low-complexity robot that handles both sweeping and light mopping without demanding much in terms of setup or ongoing configuration, the Roomba Combo Essential is a coherent and functional choice.
