Shoppers who value the Roomba ecosystem, straightforward vacuuming and a familiar support route.
iRobot robot vacuums — which one should you buy?
iRobot made 'Roomba' shorthand for robot vacuuming, but shopping the brand today requires more care than the name recognition suggests. Newer Roomba ranges sit alongside a long tail of older products, bundles and retailer stock, so it is important to separate a current model from a familiar historical one.

Do not assume an older premium Roomba is a better buy simply because it once sat at the top of the range. Current products can use a different platform and naming system.

The iRobot models that make the range easiest to understand
Not sure where to start? These are the iRobot models we’d compare first. They highlight the biggest differences across the range, so you can see where spending more is likely to help.

Roomba Max 705 Vac
A vacuum-only Roomba focused on hands-off debris emptying and modern navigation rather than mopping. It is particularly relevant to carpet-heavy homes or shoppers who prefer a dedicated vacuum robot and do not want to maintain a mop system.
- Vacuum-only focus can be a better fit for carpet-heavy homes
- Auto-empty ownership convenience
- No mopping means it is a poor fit when hard-floor washing is important
- RightRobot keeps sensing hardware separate from proven obstacle-avoidance outcomes

Roomba Max 775 Combo + AutoWash Dock
The current premium Roomba for homes where hard-floor washing and dock automation matter most. Its heated roller mop and fuller maintenance station are distinctive, but the price needs to be justified against better-established premium rivals.
- Heated self-cleaning roller mop with edge extension
- Full AutoWash dock and dual rubber vacuum brushes
- Large robot and dock need substantial floor space
- Premium price only makes sense for demanding mopping routines

Roomba Plus 515 Combo + AutoWash Dock
A current mid-range Roomba that pairs an unusually low-profile robot with automated bin emptying and mop washing. It is the useful middle step for mixed-floor homes that want more maintenance automation without moving to the Max flagship.
- Low 8.35cm robot with LiDAR navigation
- AutoWash dock empties debris and washes and dries the spinning mop pads
- Large dock still needs water-tank and bag maintenance
- Single main brush rather than the Max range's dual-rubber design

Family names are useful shortcuts, but the exact robot still matters. Similar-looking models can have different mopping systems, obstacle hardware, docks, heights and prices.
Max-series
The models to inspect when you want iRobot's higher-end current cleaning and dock options.
Plus-series
Designed to cover the middle of the range with more accessible combinations of vacuuming, mopping and dock automation.
100 / 200-class models
Worth considering when basic scheduled cleaning, compact hardware or a lower entry price matters more than a premium dock.
Where iRobot genuinely makes sense
iRobot deserves to be judged on the robot available now, not on the strength of the Roomba name. That means comparing current cleaning, navigation, dock and mopping capability directly against fast-moving rivals. For some buyers the simpler ecosystem and familiar brand remain attractive; for others, competing models now offer more automation for the money.
Three sensible ways into the iRobot range
Existing Roomba owner
Check app, parts and accessory compatibility rather than assuming your old accessories fit a new generation.
Vacuum-first home
A vacuum-only model can still make more sense than paying for mopping you will rarely use.
Comparing with newer brands
Compare obstacle avoidance, dock maintenance and mopping directly. Brand familiarity should not be treated as a performance score.
Four things to check on the exact model
Small suffixes and dock changes can matter more than the brand name.
- ✓Current versus older Roomba generation
- ✓Vacuum-only or combo
- ✓Dock type
- ✓Consumables and accessory compatibility
iRobot robot-vacuum questions
Is Roomba still the safest default robot-vacuum choice?+
It is still a major brand, but the market is much more competitive. RightRobot compares the exact current Roomba with current rivals rather than giving iRobot a familiarity bonus.
Why are there so many old Roombas online?+
iRobot has a huge installed base and retailers can keep older stock for a long time. RightRobot separates current market models from reference models where possible.
Should I choose a vacuum-only Roomba?+
Yes if mopping is not useful in your home. A simpler machine can be the better purchase when it does the job you actually need.
