iRobot Roomba 104 Combo Robot Vacuum & Mop – Renewed

iRobot Roomba 104 Combo Robot Vacuum and Mop – Intelligent Hands-Free Floor Care (Renewed)

The iRobot Roomba 104 Combo is a premium 2-in-1 robot vacuum and mop that redefines what automated floor care can accomplish. Combining an industry-leading 70x power-lifting suction with ClearView LiDAR navigation, a self-emptying dock rated for up to 75 days of hands-free operation, and an intelligent automatic carpet detection system for mopping, this robot delivers a thorough, customizable clean across all floor types. Available here as a certified renewed unit, the Roomba 104 brings flagship-level cleaning intelligence with outstanding value.

70x Power-Lifting Suction for Deep-Down Clean

At the heart of the Roomba 104's cleaning capability is its extraordinary suction system, delivering 70 times more power-lifting suction than baseline robotic vacuums. This translates to the ability to extract deeply embedded pet hair, fine dust particles, and larger debris from both hard floors and low-pile rugs in a single pass. A multi-surface brush works in tandem with the suction motor to agitate and lift debris, while an edge-sweeping brush — improved for 20% better performance at corners — ensures that baseboards and wall edges receive thorough attention rather than being skipped over as they often are with lesser robots.

The combination of powerful suction and a thoughtfully engineered brush system means the Roomba 104 can handle households with heavy pet shedding, high foot traffic, or both without sacrificing cleaning quality.

Up to 75 Days of Truly Hands-Free Operation

The Roomba 104 ships with an AutoEmpty dock that stores collected dirt in a sealed bag capable of holding debris for up to 75 days before requiring disposal. This is not merely a convenience feature — it fundamentally changes the relationship between owner and robot vacuum. Instead of emptying a small onboard bin after every run, users can set the Roomba 104 on a cleaning schedule and largely forget about it for weeks at a time.

The AutoEmpty bag traps 99% of allergens as small as 0.7 microns, meaning that when the bag is eventually removed, there is no cloud of dust or allergens released into the air. Simply lift the used bag out and drop it in the trash — a genuinely hygienic and low-effort process that particularly benefits allergy and asthma sufferers.

ClearView LiDAR Smart Navigation and Mapping

Unlike robot vacuums that rely on camera-based or infrared-only navigation, the Roomba 104 uses ClearView LiDAR technology to rapidly and accurately map your home's floor plan. LiDAR creates a precise spatial model of your living space, allowing the robot to plan efficient, methodical cleaning routes rather than the random bouncing patterns seen in older robotic vacuums. This results in better coverage, fewer missed spots, and a faster overall cleaning session.

The system also incorporates specialized cliff sensors to prevent the robot from tumbling down stairs, and the navigation algorithm is designed to steer smoothly around common household obstacles such as furniture legs, charging cables, and pet bowls. Over multiple cleaning sessions, the Roomba 104 refines its map for increasingly optimized routes.

Automatic Carpet Detection While Mopping

One of the Roomba 104's most technically impressive features is its automatic carpet detection during mopping cycles. Many combination vacuum-mop robots require manual programming or physical barriers to prevent the mopping pad from wetting carpeted areas. The Roomba 104 eliminates this friction entirely — its onboard sensors automatically detect carpeted surfaces and avoid the mopping function accordingly, keeping rugs and carpet completely dry without any intervention from the user.

Powerful and Precise Mopping with SmartScrub

Beyond vacuuming, the Roomba 104 delivers impressive mopping results thanks to a built-in micro-pump that controls water flow to the microfiber mopping pad with precision. The pad remains uniformly moist throughout the cleaning cycle, ensuring consistent surface contact without over-saturating floors. Users can select the SmartScrub mode for 2x deeper scrubbing on hard floor surfaces, making it effective against dried spills, sticky residue, and tracked-in grime that a single-pass mop would leave behind. Compatible cleaning solutions can be added for enhanced sanitization results.

Fully Customizable Cleaning via the Roomba Home App

The Roomba 104 offers exceptional cleaning customization through the dedicated Roomba Home App. Users can select from vacuum-only, mop-only, or combined vacuum-and-mop modes depending on the floor type and cleaning need. Room-by-room scheduling allows different cleaning frequencies for high-traffic areas versus low-use spaces. The app also enables keep-out zones, suction power adjustment, mopping solution flow rate control, and the number of cleaning passes per session — giving users granular control over every aspect of the cleaning process.

For users who prefer a hands-off approach, the Roomba 104 also supports voice control through compatible smart home assistants, and physical button control on the robot itself for immediate on-demand cleaning without reaching for a phone.

Connectivity and Setup

Setup is straightforward via the Roomba Home App over a 2.4 GHz Wi-Fi network. Once configured, the robot operates independently on its 2.4 GHz connection, freeing the user's smartphone to return to a 5 GHz band for optimal performance. The app also provides real-time filter life monitoring, cleaning time estimates, and session history logs.
