iRobot Roomba Combo J5 (Graphite)

How does the vacuum-to-mop conversion work?

The conversion is straightforward - simply remove the standard vacuum bin and replace it with the Roomba Combo Bin filled with water or compatible cleaning solution. The robot automatically recognises the mop bin and switches to vacuum-mop mode. When mopping, it avoids carpeted areas you've designated as No Mop Zones in the app, keeping your carpets dry whilst cleaning hard floors.

What types of obstacles can the PrecisionVision system avoid?

The camera-based navigation system identifies and avoids common household obstacles including pet waste, charging cables, socks, shoes, furniture legs and toys. It can distinguish between different object types and sizes, photographing unknown obstacles and sending images to your phone for identification. The system continuously learns and improves obstacle recognition over time.

How long does the battery last and what happens when it runs low?

The lithium-ion battery provides up to 180 minutes of continuous cleaning time. When the battery level drops below 20%, the robot automatically returns to its charging base. After recharging, it resumes cleaning from where it stopped, ensuring complete coverage of your home. Charging typically takes 3 hours for a full battery.

Can I control which rooms get cleaned and when?

Yes, the smart mapping feature allows you to name rooms and create customised cleaning schedules. Through the iRobot Home app, you can select specific rooms for cleaning, set different schedules for different areas and create Keep Out Zones or No Mop Zones. You can also start cleaning sessions remotely or use voice commands through Amazon Alexa.

How effective is the mopping function compared to traditional mopping?

The mopping function is designed for light maintenance cleaning rather than deep scrubbing. The microfiber pad effectively removes dust, light dirt and footprints from hard floors. For heavily soiled areas or sticky spills, traditional mopping may still be necessary. The robot works best for regular maintenance, keeping floors consistently clean between deeper manual cleaning sessions.

What maintenance is required for the robot?

Regular maintenance includes emptying the dustbin after each use, cleaning the filter weekly and replacing the side brush every 6-12 months. The main brushes should be cleaned weekly and replaced annually. The mopping pad should be rinsed after each use and replaced when worn. The charging contacts and sensors should be wiped clean monthly to maintain optimal performance.

Is the robot suitable for homes with pets?

Absolutely - the robot excels at picking up pet hair with its dual rubber brushes that resist tangling. The Dirt Detect Technology identifies areas with heavier pet hair accumulation for thorough cleaning. The P.O.O.P. guarantee ensures the robot avoids pet accidents and if it doesn't, iRobot replaces the unit free of charge. The 4-stage cleaning system effectively removes pet dander and allergens.

Can I use cleaning solutions in the mop function?

Yes, the robot is compatible with water or approved cleaning solutions. iRobot recommends their Braava jet cleaning solutions, but you can check their website for a full list of compatible products. Avoid using bleach, harsh chemicals, or solutions not specifically approved by iRobot as these may damage the robot or void the warranty. Always follow dilution instructions when using cleaning solutions.
