RCV 5
2 independent reviewsRead the findings →Kärcher's laser-mapping robot vacuum, with a clip-on damp mop and a charge-only base. It suits simple, regular vacuuming on one main floor type. It can snag on rug edges, and you empty its small bin yourself.

Feedback
What reviewers found
Two home tests, more than two years apart. TechRadar ran it on wood, tile and rugs in 2023, and T3 used it on carpet and hard floors in a terraced house in late 2025. Both found pickup strong and the app easy once connected. Getting around is where they part: TechRadar kept rescuing it from rug edges and toys, while T3 said it mapped accurately, crossed carpet bars easily and never got stuck. Both say the bin is small.
TechRadar, hands-on, Jun 2023 · T3, hands-on, Nov 2025
Hard floors
Reviewers rate it highlyBoth testers found pickup strong on hard floors. TechRadar called dirt and dust pickup fantastic and watched it clear scattered oats from tile, and T3 saw it quickly pick up dust and debris downstairs and spot-clean semolina from the kitchen.
Carpet and rugs
Not enough evidenceOnly T3 clearly tested carpet pickup, finding it lifted dust, hair and dog fur from thick carpet on its boost setting. TechRadar's rug trouble was about getting onto rugs, not cleaning them.
Pet hair
Not enough evidenceOnly T3 tested it with pet hair, finding it lifted dog fur well but filled its small bin quickly and needed hair unwound from the brush regularly, as there's no anti-tangle design.
Mopping
Mixed resultsIt's a light wipe rather than a scrub. T3 found water spread evenly with no damp patches, fine for freshening floors between proper cleans, and TechRadar liked it too, but there's no dirty-water tank and you rinse the cloth yourself.
Navigation and obstacles
Mixed resultsThe testers disagree. T3 found it mapped accurately, crossed carpet bars easily and never got stuck, while TechRadar kept rescuing it from rug edges, where the mop plate snagged, and from behind children's toys.
App and software
Reviewers rate it highlyOnce connected, both testers liked the app's room settings, no-go zones and schedules. Setup was fiddly: T3 had to connect it next to the router, and TechRadar found the app listing confusing.
Noise
Reviewers rate it highlyBoth found it quiet: TechRadar and T3 likened it to normal conversation, and T3 called it one of the quieter robots it has tested.
Reliability and support
Not enough evidenceNone of the reviews we use has run it long-term or judged Kärcher's support yet.
Value
Mixed resultsTechRadar found it competitively priced, while T3 thought it a little expensive for a robot that neither empties itself nor washes its mop.
Verdicts come from independent, hands-on, finished reviews. An area needs at least two of them before we say more than “Not enough evidence”. We don't score robots ourselves. How this works
Rugs split the two testers
TechRadar found it regularly got stuck climbing onto rugs, and worked out that the mop plate and cloth were catching on the edge; with them removed, it made the climb. It also got stuck behind children's toys and spun in circles before settling into a route. T3 had the opposite experience, with the robot rolling over carpet bars without effort and never getting stuck. Neither review explains the difference. If your rugs have raised edges, watch the first few runs, and try vacuum-only runs with the mop plate off.
Strong pickup on both floor types
TechRadar called dirt and dust pickup fantastic and watched it clear a path through oats scattered on tile. T3 found it lifted dust, hair and dog fur from thick carpet on its turbo setting, and cleared semolina from a kitchen floor with a spot clean. So pickup isn't the worry here. It also raises suction when it senses carpet, which T3 found useful in a home with a shedding dog.
The mop is a light wipe
T3 described the mopping as a wipe-over rather than a scrub, with water spread evenly and no damp patches, which is fine for keeping hard floors fresh between proper cleans. TechRadar liked the mopping too, but points out there's no dirty-water tank: clean water goes down and the cloth picks up the residue. Nothing washes the cloth for you, so plan to rinse it after each mopping run. With mopping switched on, the robot steers around carpet it has detected.
Small bin, frequent emptying
T3 found the 330ml bin filled quickly with pet and human hair, and had to unwind hair from the main brush regularly because there's no anti-tangle design. TechRadar suggests emptying it after every other run. That's the price of the tiny charging base: nothing is emptied for you. With a pet that sheds, expect to handle the bin most days, and keep a pair of scissors near the brush.
Setup can be fiddly
T3 couldn't connect it to Wi-Fi upstairs and had to set it up right next to the router, after which it stayed connected. TechRadar found the app listing confusing and had better luck scanning the QR code in the box. Both then liked the app, with room-by-room settings, no-go zones, schedules and accessory wear. There's no camera you can watch remotely, which TechRadar missed when the robot got stuck with nobody home.
The two tests were in June 2023 and November 2025, in different homes; neither explains why their navigation results differ.
Our take
Should you buy the RCV 5?
Best for: Tidy homes where someone will empty the bin after cleaning. Skip it if: You have lots of carpet or leave small objects on the floor.
Buy it if you want a simple, well-built robot for regular vacuuming, your floors are mostly one type, and you don't mind emptying the bin often. Skip it if you have rugs with raised edges, toys on the floor or want the robot to look after itself. The Roborock Q7 M5 covers the same basic cleaning with a stronger test record, and the Dreame D10 Plus Gen 2 empties itself.
The RCV 5 is the smarter of Kärcher's two robot vacuums. It sits above the RCV 3, adding a laser-and-camera sensor meant to spot cables, socks and shoes, and it maps your home with a spinning laser on top. It vacuums, and it can drag a damp cloth behind it from a small water tank. It went on sale in the UK in early 2023, so it's an older design than most robots it now competes with.
The trade-off is how much you do yourself. There's no self-emptying dock and no mop washing: the base only charges it, so you empty a small bin, rinse the cloth and pull hair off the brush. In return the base is tiny and the robot is just under 10cm tall. The bigger question is getting around, because the two people who tested it had very different experiences with rugs.
Before you buy
The questions people ask about this one
Can it cross rugs and raised thresholds between rooms?
It depends on your rugs. TechRadar had it stuck on rug edges repeatedly, partly because the mop plate snagged, while T3 saw it cross carpet bars with no effort. T3 quotes a 20mm climbing height, but neither review measured it. If it struggles, try it with the mop plate removed.
Will it avoid cables and pet mess?
Kärcher says its laser-and-camera sensor spots flat objects such as cables, socks and shoes, per the specifications. T3 found it steered around cables and shoes, but TechRadar had it stuck behind toys. Neither tested pet mess, so don't trust it near an accident.
How often do I have to empty or refill anything?
Often. The bin holds 330ml and the water tank 240ml, per the specifications, and nothing empties itself. TechRadar suggests emptying the bin after every other run, and T3 found it filled quickly with pet hair. You'll also rinse the mop cloth yourself.
Does it fit under low furniture?
Usually. TechRadar lists it at 9.7cm tall and T3 at just under 10cm, and both saw it clean under sofas and other furniture. Measure the gap first: anything lower than about 10cm will stop it.
How big is the dock, and is it loud?
The base is tiny, 135 by 150mm and 99mm tall according to the specifications, because it only charges. Kärcher rates the robot at 66dB, and both TechRadar and T3 found that believable, comparing it to normal conversation. T3 called it one of the quieter robots it had tested.
Does it work without Wi-Fi?
Only for basic runs. T3 notes you can start a plain vacuum run with the button on top, but mopping options, room settings, schedules and no-go zones need the Kärcher Home Robots app. the specifications says the app's data runs through servers in Germany.
Alternatives
Other robot vacuums to compare.
Q7 M5 / M5+
Why consider it: A budget mapping robot that testers found strong on vacuuming and pet hair.
The compromise: It bumps into clutter and, like the RCV 5, leaves all the emptying to you.
D10 Plus Gen 2
Why consider it: Maps your home and empties itself into a bag for up to three months.
The compromise: Weak on thick carpet, and it runs over cables and socks.
RV30 Max Plus
Why consider it: Laser mapping, methodical cleaning and a compact dock that empties the bin.
The compromise: Fine grit and sticky spills beat it in testing.
