Four robot vacuums run in my house right now. A Dreame D20 Air Plus, a Narwal Freo 20 Edge, a Narwal Freo Z10 Turbo and a Lefant M5 Pro share carpet, tile and wood, some large rooms and a staircase none of them can climb. When I reviewed them, their list prices ran from $349.99 to $899.99.
So here is what I'd stop paying for, what I'd keep, and what I'd tell a friend to buy. The short version is that I'd pay for reliable navigation, a useful dock and proven pickup long before a camera or a bigger suction number.
None of my four robots has a camera
The first thing I'd stop paying for is camera-based obstacle avoidance. Laser navigation has come a long way, and for the way I use these robots it does the job just as well. All four of mine map with LiDAR or laser sensors. The two Narwals add laser or structured-light obstacle sensing, the Lefant has its own obstacle sensors, and the Dreame relies on its bumper and cliff sensors up close. Not one of them points a camera at my living room.
I value privacy, and I'd pick a camera-free robot any day. The worry isn't imaginary either. In 2022, MIT Technology Review reported that images captured by development versions of a camera-equipped Roomba, including one of a woman on a toilet, were shared in private social media groups by workers hired to label them. iRobot said those were test units given to paid collectors and employees, not robots sold to customers. I'd still rather my vacuum had nothing to capture.
There is a trade. A thin charging cable or a stray sock can still get past some of these sensors, so a quick floor check before a run is sensible. I'll take that deal.
Voice control, 3D maps and other things I never use
Voice commands are next. I never really use them. I use automations and quick shortcuts instead, and when I have tried voice, it either couldn't hear me or got it wrong.
The fancy 3D furniture map goes on the same pile. It's nice to look at. It hasn't added anything practical for me.
Hot-water numbers too. I'll pay for a dock that washes the mop and dries it. I wouldn't pay more because the wash temperature on the spec sheet went up.
Suction numbers are the megapixels of robot vacuums
They're easy to print, easy to compare, and a poor guide to what ends up in the bin. Past a certain point, more pascals don't make much of a difference, and the number on the box doesn't always match what I see on the floor.
| Robot | Suction on the box | List price when I reviewed it | My rating |
|---|---|---|---|
| Lefant M5 Pro | 18,000 Pa | About $799.99 | 9.4 out of 10 |
| Dreame D20 Air Plus | 20,000 Pa | $349.99 | 9.0 out of 10 |
| Narwal Freo Z10 Turbo | 25,000 Pa | $899.99 | 9.3 out of 10 |
| Narwal Freo 20 Edge | 31,000 Pa | $799.99 | 9.5 out of 10 |
The cheapest robot in the house claims more suction than one that listed for more than twice as much, and I rated the smaller number higher. A pascal figure is pressure measured with the air inlet blocked, which isn't how a vacuum spends its day. Narwal's own explainer says a high Pa figure doesn't guarantee better cleaning, and points to airflow, brush design and how well the system is sealed.
What I'd pay for
- Mapping and navigation I can trust. This is the real time saver. A robot that maps properly and finds its way is one I have to manage less.
- A dock that empties the bin. It takes away most of the ongoing maintenance.
- Obstacle avoidance that works. It no longer takes a camera to get it.
- Automatic mop washing and drying, if the robot mops at all.
- Pickup that's proven on your kind of floor. I have carpet, tile and wood, so mine has to handle all three.
The robot that fixed the smell
One feature did surprise me, and it was the mop on the Narwal Freo 20 Edge. It cleans itself while it works. Sixteen nozzles spray clean water onto the mop track as it moves, a scraper strips the dirty water off, and the system extracts that water instead of spreading it around the house.
I've had robot mops turn sour within a few runs, self-cleaning docks included. This one hasn't. Run after run, I'd lift it and find a mop that looked clean and had no smell.
The Lefant M5 Pro earns a mention as well. Its roller is fed fresh water as it spins and a wiper scrapes the dirty water away, and it was the robot that finally made me trust one to mop.
A flat damp pad under the back of the robot, like the one on my Dreame, is a different thing. It's a wipe for the stretch between proper mops, and at that price it's a bonus.
What wears on you after the first month
The annoyances aren't on the spec sheet either. These are the ones I've run into across the robots I've had.
- Mops that get dirty, start to smell and never really clean themselves.
- Robots that lose track of their dock. I've had to recall one repeatedly and then carry it back myself.
- Filters, brushes and mop pads that need replacing.
- Repeated rescues. Some robots hit the same obstacle over and over, as if they'd never seen it before.
- Hair wrapped around the brushes and wheels.
What I'd tell a friend
Around $250. Mopping is a bonus at this price. I'd look for a robot that's accurate, picks up reliably, gets back to its dock consistently and empties itself, because the point is not having to babysit it. You don't need a camera. LiDAR is fine. The Dreame D20 Air Plus is the one I'd point to. It lists at $349.99, and I've seen it discounted well below that.
Around $500. Now it should vacuum and mop, and it should know what to do when it reaches carpet. Both the Narwal Freo Z10 Turbo and the Lefant M5 Pro were $599.99 on promotion when I reviewed them, so it pays to wait for a sale.
$1,000 or more. Before you spend that, I'd ask four questions. Will it clean your particular floors well? Will it finish a job without needing you? How much cleaning does the dock itself need? And what happens when something wears out?
Some homes shouldn't have one at all. I'd skip it if your space is small, if the floor is usually covered in things and loose cables, or if you have outdoor pets that regularly have accidents inside.
The best robot vacuum is the one you stop thinking about. Reliable navigation, a dock that looks after itself and proven pickup get you there. A camera and a bigger number on the box don't.
