Does the Roomba 105 actually work on carpet?
Worth it, with modest carpet expectations
Why carpet is where robot vacuums get tested
You know the feeling: bare feet on the carpet by the coffee table, and there it is, that fine grit an upright always seems to miss down in the pile. You look at the little robot vacuum in the corner and think, that's fine for the kitchen tile, but does Roomba actually work on carpet, or does it just skate over the top and call it done? That doubt is the whole reason most people hesitate before buying one for a house that isn't all hardwood.
How the Roomba 105 actually cleans carpet
Here's what I'd want to know first: carpet is a harder job for any vacuum than tile, because dirt doesn't sit on top of it, it works down into the fibers. The Roomba 105 handles that with a three stage system rather than one strong motor. A rubber multi surface brush agitates the pile to lift trapped dirt up where suction can reach it, an edge sweeping brush pulls debris out from baseboards and corners it can't otherwise reach, and the motor pulls with what iRobot calls 70x more lifting power than the older 600 series, enough to pull dust out of low and medium pile carpet instead of skimming across it. The ClearView LiDAR on top isn't there for the carpet part specifically, it's there so the robot maps the room before it starts, which means it cleans in tidy overlapping rows instead of the old random bounce pattern, and that matters on carpet because a robot that revisits the same six feet three times and skips the rest isn't actually cleaning it, it's wandering. You can bump the suction up a level in the app for a rug that needs it, or set a keep out zone around a shag mat it won't handle well. When the battery fades, around 200 minutes in, it heads back to the dock on its own, charges, and picks up roughly where it left off, so a big open plan floor still gets finished without you doing anything.
So the honest answer to does it work on carpet is yes, for everyday low and medium pile stuff, because the brush and suction combination was built for exactly that job, not just tile. What you're really buying isn't a vacuum that replaces your upright, it's a robot that runs the daily maintenance pass so the upright has less to do when you do pull it out. The carpet question resolves into a simpler one: is your carpet low enough for a robot's brush to reach into, or thick enough that only a full-size vacuum will do.
Who the Roomba 105 is for, and who should skip it
Worth it if
- your home is a mix of hard floor and low to medium pile carpet
- you want daily upkeep instead of one big weekly vacuum session
- you have pets shedding onto carpet and rugs
- you're fine setting a schedule through an app and emptying a bin by hand
Skip it if
- your carpet is thick, shag, or high pile
- you want a self-emptying base with no manual bin work
- you need one deep clean rather than daily light passes
Not for homes with thick shag or deep pile carpet that really needs a full-size upright.
The Roomba 105 carpet verdict: is it worth it
If your floors are a normal mix of hard floor and low to medium pile carpet and you want the daily crumb patrol handled without touching a vacuum, this is a quiet yes. If you've got thick shag rugs, deep pile carpet, or a house that just needs one big weekly clean rather than daily upkeep, save your money for a full-size vacuum instead.
Picture the actual first week: you set a schedule once in the app, and the fine grit by the coffee table stops building up between big cleans, because something is quietly working the carpet over every day instead of once a week. A very large number of owners land on this one as a real improvement specifically for pet hair pickup, though it's worth going in with modest expectations about how the battery holds up years down the line rather than months. Set it, forget it, and let the crumbs lose.

Before you go
What is a disadvantage of using a Roomba?
The main tradeoff is depth on carpet: thick or high pile rugs need more agitation than any robot's brush can supply, so it won't replace a full-size vacuum on those surfaces.
Are Roombas effective on carpet?
Yes on low to medium pile, the multi-surface brush and boosted suction lift embedded dirt out of the fibers, though thick pile carpet is still better served by an upright.
Is a robot vacuum worth it for carpet?
It's worth it if you want daily upkeep on normal carpet and hard floors, less so if your home is mostly deep pile carpet that needs one stronger, single-pass clean.
