iRobot Roomba 104 2in1 Vacuum & Mop Robot - Self-Emptying, LiDAR

In this review of the Roomba 104 Combo Robot, the bottom line is simple: this robot is best for households that need a mostly hands-off vacuum and mop solution, especially where pet hair and mixed flooring are common. The biggest reason to buy is its long interval between maintenance cycles - the AutoEmpty dock holds up to 75 days of debris in a disposable bag that traps most allergens - which makes routine care far less frequent than many competitors. The review covers navigation, cleaning performance, app control and real-world limitations to help readers decide if it fits their home.

Key Features

• 70X power-lifting suction: Provides intense suction that pulls dirt and pet hair from carpets and hard floors for more thorough pickup than basic robot vacs.
• AutoEmpty dock: Holds up to 75 days of debris in a bag that captures 99% of allergens down to 0.7 microns, reducing dust exposure when emptying.
• ClearView LiDAR mapping: Quickly maps rooms for efficient coverage and smooth obstacle avoidance, improving navigation in cluttered spaces.
• Vacuum and mop combo: Uses a washable microfiber pad and a micro-pump to control water flow so floors get a uniform wipe and SmartScrub option for deeper scrubbing.
• Automatic carpet detection: Stops mopping over rugs automatically so carpets stay dry without manual no-go zones or extra programming.
• Custom app controls: The Roomba Home app lets users schedule cleans, target rooms, adjust suction and mopping levels, and create keep-out zones.

Who It's For

The Roomba 104 is ideal for busy households with pets and a mix of carpet and hard floors that value long stretches of hands-free operation and allergen containment. People who like set-and-forget cleaning will appreciate the 75-day AutoEmpty bag and LiDAR mapping for consistent navigation.

It is less suited for buyers who need perfect reliability under heavy daily use or those who expect flawless long-term charge retention and zero mechanical hiccups; some users have reported sporadic functionality issues and occasional items getting caught under the robot, so heavy tinkerers or those seeking a completely maintenance-free lifetime experience should look elsewhere.

Pros & Cons

Pros

• Strong suction and multi-surface brush combine to pick up pet hair and debris effectively.
• AutoEmpty dock reduces maintenance to roughly monthly or less with a 75-day capacity and allergen-trapping bags.

• Integrated mop with micro-pump and SmartScrub delivers visibly cleaner hard floors than vac-only robots.

Cons

• Some customers report intermittent functionality problems, such as the robot stopping unexpectedly or side brush issues.
• Charge retention and long-term durability receive mixed feedback, so expect occasional troubleshooting.
