iRobot Roomba 104 Combo 2-in-1 Vacuum & Mop Review

iRobot Roomba 104 Combo Robot Vacuum & Mop: A Complete Overview

The iRobot Roomba 104 Combo represents the latest evolution in robotic floor care, combining powerful vacuuming and mopping capabilities into a single, intelligent machine. Designed to handle the demands of modern households, this 2-in-1 robot takes the hassle out of daily cleaning by automating both dry debris pickup and wet floor scrubbing. With its included AutoEmpty Dock that stores up to 75 days of dirt, the Roomba 104 Combo is engineered for hands-free convenience that few competitors can match.

At the heart of this robot vacuum is iRobot's commitment to thorough, adaptive cleaning. Whether you have wall-to-wall carpet, hardwood throughout, or a mix of surfaces, the Roomba 104 Combo adjusts its approach in real time. For pet owners, allergy sufferers, and busy families, this machine offers a compelling solution that works quietly in the background while you focus on what matters most.

Key Features

70X Power-Lifting Suction

The Roomba 104 Combo delivers 70 times more suction power compared to iRobot's earlier Roomba 600 series. This substantial leap in cleaning performance means the robot can extract embedded dirt, fine dust, and stubborn pet hair from carpets and hard floors with remarkable efficiency. The 4-stage cleaning system combines the intense suction with an edge-sweeping brush that cleans corners 20 percent better than its predecessors, a multi-surface rubber brush that adapts to different floor types, and a washable microfiber mopping pad for hard surface refinement.

ClearView LiDAR Navigation

Precision navigation is one of the standout features of the Roomba 104 Combo. The ClearView LiDAR system rapidly maps your entire home, creating a detailed floor plan that enables methodical, row-by-row cleaning rather than random bouncing. This technology ensures complete coverage of every room while intelligently steering around furniture, obstacles, and drop-offs like staircases. Through the companion app, you can view the map, designate specific rooms for targeted cleaning, and create keep-out zones to protect sensitive areas.

AutoEmpty Dock with Allergen Lock

The included AutoEmpty Dock automatically empties the robot's dustbin after every cleaning session, storing debris in a sealed bag that traps 99 percent of allergens as small as 0.7 microns. The bag holds up to 75 days of accumulated dirt before requiring replacement. When it is time to swap the bag, you simply lift it out and dispose of it without ever touching the dust or releasing particles back into the air. This is a meaningful advantage for allergy-conscious households.

Smart Mopping with SmartScrub

The integrated mopping system uses a micro-pump to control water flow precisely, keeping the microfiber pad uniformly moist throughout the cleaning cycle. You can choose between water alone or a compatible cleaning solution for deeper sanitization. The SmartScrub mode engages a back-and-forth scrubbing motion that delivers two times deeper cleaning of high-traffic areas, mimicking the manual scrubbing motion you would use by hand. Critically, the robot automatically detects carpet and avoids it while mopping, so your rugs stay completely dry without any programming on your part.

Best For

The iRobot Roomba 104 Combo is best suited for multi-surface homes where both vacuuming and mopping are needed on a regular basis. Pet owners will appreciate the powerful suction and self-emptying dock that minimizes contact with fur and dander. Busy professionals and families who want a set-it-and-forget-it cleaning solution will benefit from the scheduling capabilities, voice assistant integration, and extended hands-free operation. The allergen-trapping dock also makes this an excellent choice for households with allergy or asthma concerns.

Performance & Design

In terms of physical design, the Roomba 104 Combo maintains iRobot's signature low-profile circular form factor in a sleek black finish. It measures 33.5 centimeters in diameter and just 10.4 centimeters in height, allowing it to slip beneath most furniture for thorough under-sofa and under-bed cleaning. The unit weighs approximately 6.8 kilograms, which is standard for a full-featured robot vacuum with mopping capability.

Operation is flexible, with three control methods available. You can schedule and initiate cleaning through the Roomba Home app, press the physical buttons on the robot itself, or use voice commands through Alexa, Siri, or Google Assistant. The app provides detailed insights including cleaning time estimates, filter life monitoring, and granular controls for suction power levels, mopping solution output, and the number of cleaning passes per room.

The Roomba 104 Combo connects via 2.4 GHz Wi-Fi, which is standard for robotic vacuums and ensures reliable communication with your home network. While the 3.7 average user rating suggests some owners have encountered issues, the combination of advanced LiDAR mapping, powerful suction, intelligent carpet avoidance during mopping, and the exceptionally convenient 75-day self-emptying dock positions this robot as a capable all-in-one floor care solution for demanding households.
