iRobot Roomba i3+ EVO (3550) Self-Emptying Robot Vacuum – Now Clean by Room with Smart Mapping, Empties Itself for Up to 60 Days, Works with Alexa, Ideal for Pet Hair, Carpets , Roomba i3+
What’s in the box
You’ll typically find the robot vacuum, the Clean Base automatic dirt disposal unit, a power cord for the base, a replacement disposable bag for the Clean Base, and some documentation. The included starter bag in the Clean Base means you can get started cleaning right away without hunting for accessories.
Accessories and replaceable parts
You’ll get a combo brush system and side brushes installed, and the package usually includes at least one extra set of consumables depending on the retailer. It’s helpful to keep replacement filters and bags on hand so your maintenance routine doesn’t interrupt operation.
Key features overview
You’ll appreciate that this model is Wi‑Fi connected and controlled through the iRobot Home app and voice assistants like Alexa and Google Assistant. Its headline features are a Premium 3‑Stage Cleaning System, 10X Power‑Lifting Suction, Smart Mapping with Clean by Room, and an automatic dirt disposal system that can hold up to 60 days of dirt.
Design and build quality
The Roomba i3+ EVO has a clean, utilitarian aesthetic that prioritizes function and serviceability. You’ll notice durable plastics and a simple top panel with clearly labeled controls, which makes it easy to operate manually if you prefer.
Size and form factor
The low profile helps it get under furniture and sofas, while the circular design is standard for Roombas and helps with turning in tight spaces. If you have very low-clearance furniture, you’ll want to measure to ensure it fits.
Performance and cleaning power
In everyday use, this robot pulls in dirt reliably thanks to the combination of its suction and brush system. The Premium 3‑Stage Cleaning System tackles surface debris, fine dust, and pet hair, and the 10X Power‑Lifting Suction boosts its ability to lift trapped particles from carpets.
Suction and 3-Stage Cleaning System
The combination of dual multi-surface rubber brushes, side brushes, and strong suction gives you a balanced approach to different surfaces. You’ll find it handles hard floors and low- to medium-pile carpets well, and it’s explicitly tuned to lift pet hair without getting tangled as often as bristled designs.
Cleaning modes and navigation
You can start basic cleaning cycles directly on the robot or via the app. The robot learns patterns and will follow efficient cleaning paths, though it doesn’t have the hyper-advanced obstacle negotiation of some higher-end models. For most homes, you’ll get consistent coverage with minimal supervision.

Smart Mapping and “Clean by Room”
Smart Mapping lets the robot learn and remember room layouts so you can tell it to clean specific rooms or zones. You’ll set up maps through the iRobot Home app and then label rooms, which lets you send the Roomba to do targeted cleans when you want.
How mapping improves your routine
With Clean by Room, you only need to ask the robot to clean the kitchen or the bedrooms rather than the whole house every time. You’ll save runtime and focus cleaning where it matters most, which is handy after meals or when pets concentrate hair in certain spaces.
Automatic Dirt Disposal (Clean Base)
The Clean Base Automatic Dirt Disposal is one of the biggest convenience features: it allows the Roomba i3+ EVO to empty itself into a sealed bag inside the base, reducing how often you need to handle dirt. You’ll likely only need to change the bag every few weeks or up to 60 days, depending on usage and home conditions.
Practical benefits of self-emptying
You’ll avoid frequent contact with dust and allergens, which is a big plus if you’re allergy-prone or have pets. The sealed bags also make disposal tidier and reduce dust clouds that arise when you empty a traditional dustbin.
iRobot Home App and smart features
The iRobot Home app controls the cleaning schedule, maps, and preferences and offers personalized suggestions like seasonal recommendations or extra cleans during high-pollen periods. You’ll find the interface straightforward for basic scheduling and room-based control.
App usability and updates
The app is designed to get better over time, and iRobot rolls out updates to add features and performance tweaks. You’ll be able to start, stop, and schedule cleans, review cleaning history, and tweak preferences from your phone.
Personalized schedules and recommendations
The robot learns your habits and suggests schedules based on them, which can save you time configuring settings. You’ll receive suggestions like extra cleaning during pet shedding season or high pollen days, which is helpful if you want proactive maintenance.
Voice Assistant compatibility
You can start cleaning with simple voice commands through Google Assistant or Alexa, which integrates nicely into a smart home setup. You’ll appreciate being able to trigger a room clean without getting up or opening your phone.
Limitations of voice control
Voice control handles start, stop, and room-specific commands but won’t replace the app for map edits or detailed scheduling. You’ll still need the app for initial setup and to manage mapping or advanced settings.
Battery life and charging
The i3+ EVO offers enough runtime for most medium-sized homes, and it returns to its Clean Base to recharge when needed. If a job runs longer than available battery, the robot will dock, recharge, and resume cleaning where it left off.
Real-world runtime expectations
Battery life varies by suction mode and home layout, but you can expect typical runs to last long enough to cover individual rooms or moderate apartments. You’ll want to consider your home size for whole-house cleaning in one session.
Noise levels
You’ll notice the robot is louder than passive floor maintenance but quieter than many full-size vacuums. Noise increases when the suction ramps up, and the Clean Base emits a stronger sound during the automatic emptying cycle.
Living with the noise
If you’re working from home or have a baby who naps during the day, you’ll want to schedule cleans for times when noise is less disruptive. The sound level is generally acceptable for daytime operation, but it’s not whisper-quiet.
Maintenance and consumables
Maintenance is straightforward: you’ll empty filters, clean the brushes, and replace the Clean Base bag and filters periodically. Keeping the brushes and sensors clear will preserve performance and help the robot navigate effectively.
Consumable lifespan and replacement
Filters and brush life depend on usage and debris types, but you should expect to replace filters and Clean Base bags every few months under typical use. You’ll want replacement parts on hand if you rely heavily on the robot for daily maintenance.
Setup and first run
Getting started is simple: place the Clean Base on flat ground near a power outlet, charge the robot, download the iRobot Home app, and follow the pairing steps. The first run helps the robot create an initial map which you can then edit and label.
Tips for a smooth setup
Before the initial run, clear the floors of cables, small toys, and potential tangle hazards. You’ll also want to define virtual barriers in the app or set up physical limits for areas you don’t want it to access.
Obstacle handling and boundary limits
The robot can handle common obstacles like chair legs and thresholds up to a certain height, but fragile items and cables can cause issues. You’ll want to tidy clutter and use the app’s mapping features to block off sensitive zones if needed.
What it detects and what it misses
Patented Dirt Detect Technology helps the robot find dirtier spots and concentrate cleaning there, but small items on the floor or very reflective surfaces may confuse its sensors. You’ll benefit from occasional supervision when first using it in new environments.
Pet hair performance
If you have pets, this model is explicitly marketed as ideal for pet hair thanks to its rubber brush system and strong suction. You’ll find it captures loose fur and reduces surface hair build-up between deeper cleans.
Managing pet dander and allergens
The sealed Clean Base and included filters help reduce your exposure to allergens, and the app’s suggestions can prompt you to run extra cleans during heavy shedding seasons. You’ll still want regular deep cleaning and manual attention to upholstery for the best allergy control.
Flooring and carpet compatibility
The i3+ EVO performs well across hard floors and low-to-medium pile carpets, with automatic adjustments for surface type. You’ll get consistent results on tile, hardwood, laminate, and area rugs, but very thick or high-pile carpets will limit brush and suction effectiveness.
Transitioning between surfaces
The robot’s wheels and motor handle typical transitions and small thresholds, and the 3-Stage Cleaning System adapts to different textures. You’ll find it manages between hardwood and rugs without getting stuck in most homes.
Troubleshooting and support
Common issues like connectivity hiccups, stuck brushes, or bump sensor errors can often be solved by restarting the robot, checking the app for alerts, and cleaning sensors. If problems persist, iRobot’s support channels and community forums are resources you can use.
When to contact support
If you see persistent navigation failures, repeated error codes, or battery problems, reach out to iRobot support with your model and software version. You’ll be guided through diagnostics and potential warranty options.
Security and privacy considerations
Because the robot connects to Wi‑Fi and stores home maps, you’ll want to be mindful about account security and grant only necessary permissions. You’ll also be able to control what data is shared through your iRobot account settings.
Data handling and map storage
Maps are stored on iRobot servers to enable features like Clean by Room, and you can manage how those maps are used within the app. You’ll have options to rename, delete, or refine maps to keep your setup organized and private.
Upgrades and future-proofing
The iRobot Home app receives updates that can add features, including mapping improvements and personalization. You’ll benefit from periodic firmware updates that refine navigation and expand capabilities.
Expandability and accessory ecosystem
If you want extra convenience, you can buy replacement Clean Base bags, extra filters, and brush kits directly from iRobot or third-party sellers. You’ll also find other Roomba accessories that can extend the robot’s usefulness and lifespan.
