Robot Vacuum Buying Guide 2026:
What Really Matters
Before you buy a robot vacuum with an all-in-one station, you should understand these differences. Our guide explains Pascal figures, washing temperatures, mopping systems and navigation technology in plain language – and shows which advertising claims are actually verified.
Suction power – how many Pascal do you really need?
Suction power in Pascal (Pa) is the most heavily advertised figure for robot vacuums and at the same time the least meaningful. There is no standardised measurement method: every manufacturer measures in its own lab using its own procedure. Brush design, airflow routing and the size of the intake opening influence the result at least as much as the vacuum itself.
18,000–19,000 Pa (ECOVACS DEEBOT T80 OMNI, MOVA P50 Pro Ultra)
A solid figure for the mid-range that is sufficient in practice for hard floors and short-pile carpet.
30,000 Pa (MOVA P70 Pro Ultra, Dreame L50s Pro Ultra)
The highest nominal figure in this comparison, generated according to MOVA by a motor spinning at up to 120,000 rpm. Both numbers come from internal lab tests. What they deliver in practice is more nuanced: in measurements by smarthomeassistent.de the P70 Pro Ultra scored 98.3 out of 100 points on hard floors, but only 68.71 out of 100 on high-pile carpet.
Mop washing: why temperature counts
In 2026 the station's washing temperature has become the new competitive battleground – and arguably the most relevant differentiator, because it has a direct effect on hygiene and odour.
40–75 °C: the class standard
Most stations wash in this range, including the ECOVACS DEEBOT T80 OMNI (40–75 °C), the MOVA P50 Pro Ultra (75 °C) and the Roborock Qrevo Curv (75 °C). That is sufficient for everyday use and handles normal soiling.
100 °C: the new top tier
MOVA and Dreame quote 100 °C for their current models. An important point for understanding: this refers to the surface temperature of the PTC heating element on the washboard, not the water temperature. On the MOVA P70 Pro Ultra, however, practical evidence is available – TÜV Rheinland has confirmed a germ reduction of 99.9999 % against Staphylococcus aureus, E. coli, Candida albicans and Klebsiella pneumoniae.
Drying is the underrated factor
Almost more important than the washing temperature: how quickly and how hot are the mops dried afterwards? If they stay damp in the station for hours, odour develops and ends up on the floor during the next run. Many models need two to four hours at 40 to 50 °C. The P70 Pro Ultra dries at 70 °C in around an hour and is therefore ready for use again far sooner.
Mopping technology: rotating pads vs roller
Mopping is where the clearest conceptual difference between manufacturers shows – and it has direct consequences for everyday use.
Two rotating mop pads (MOVA, Dreame, Roborock)
Two plates spin at high speed (260 rpm on the P70 Pro Ultra) and press onto the floor with a defined force (12 N). Advantage: vigorous mechanical scrubbing that deals with dried-on stains. Disadvantage: whatever the pad picks up stays in it until it is washed again – with a lot of wet dirt it smears more quickly and the robot has to return to the station more often.
Self-rinsing mop roller (ECOVACS OZMO ROLLER)
A continuous roller is flushed with fresh water while the robot drives and removes dirty water as it goes. Advantage: consistent results even across larger areas, with no smearing. Disadvantage: less concentrated pressure than rotating pads.
Extendable mops for edges
Neither concept manages wall edges without help. Modern models therefore extend the mop or side brush sideways – on the P70 Pro Ultra the RoboSwing mechanism extends the mop by up to 4 cm, for which TÜV SÜD has certified coverage of up to 100 %. Make sure a machine has this function if your floor plan has lots of corners and skirting boards.
Anti-tangle: the most important point for households with hair
The most common source of frustration in day-to-day robot vacuum use is not dust or stains but hair wrapping around the brush and wheel axles, which then has to be cut away. Anti-tangle brushes work with comb teeth or cutting edges that release hair mechanically and move it into the bin.
One question is decisive when buying: is this system included as standard? On the MOVA P70 Pro Ultra the answer is no – MOVA advertises a triple anti-tangle system but notes explicitly in its disclaimer that the CleanChop brush required for it is available separately. What comes in the box is a plain rubber main brush. The corporate sibling Dreame L50s Pro Ultra includes its DuoBrush as standard, and even the older and cheaper MOVA P50 Pro Ultra already has the CleanChop brush on board.
Marketing or verified? How to read a specification sheet properly
Robot vacuum specification sheets are full of percentages with lots of nines. Whether an independent test lies behind them is almost always revealed in the small print. The MOVA example illustrates this well:
| Claim | Source according to the manufacturer | Reliability |
|---|---|---|
| 99.9999 % sterilisation rate | TÜV Rheinland, report no. 704012511339-00 | Externally verified |
| Up to 100 % edge coverage | Certified by TÜV SÜD | Externally verified |
| 30,000 Pa suction power | Internal lab tests | Self-declared |
| 120,000 rpm motor speed | Internal lab tests | Self-declared |
| 99.99 % dirt and hair pick-up | Internal lab tests | Self-declared |
| 99.9 % pet and waste detection | In-house lab tests | Self-declared |
The rule of thumb is simple: if a testing body is named along with a report number, the claim can be checked. If that is missing and the wording is "based on internal lab tests" instead, it is a self-declared figure – not necessarily wrong, but not comparable either. To MOVA's credit, it lists this distinction transparently in its own disclaimer. Not every manufacturer does.
Placement: the factor people forget
All-in-one stations are big. The station of the MOVA P70 Pro Ultra measures 420 × 458 × 470 mm, roughly the size of a small bedside table. Before you buy, check:
- A free footprint of around 50 × 60 cm plus manoeuvring room for the access ramp in front of it
- A power socket within reach – the station stays permanently connected
- A hard floor as the location, so that any escaping water does not soak into carpet
- A clear approach path: at least 0.5 m of space at the sides and 1.5 m in front so the robot can dock cleanly
- Compare the robot's height (103.8 mm here) with the underside of your sofa, bed and sideboard
- Measure your door thresholds and check them against the stated obstacle clearance
Care & maintenance in everyday use
Even the lowest-maintenance station does not run entirely without care. Realistically, expect a brief task once a week and a more thorough clean once a month:
- Refill the station's clean water tank regularly (4.0 l capacity on the P70 Pro Ultra)
- Empty the waste water tank regularly to avoid odour (3.5 l)
- Replace the station's dust bag when it is full (3.2 l)
- Clean the washboard and its filter – washing performance drops noticeably when they are dirty
- Occasionally remove hair and lint from brushes and wheels manually, despite the anti-tangle system
- Wipe dust off sensors, the laser turret and the camera with a dry cloth to avoid navigation errors
- Install firmware and app updates promptly – navigation problems in particular are often improved by updates
MOVA, Dreame, ECOVACS and Roborock – an honest brand comparison
MOVA (China, sub-brand of Dreame)
Strengths: very aggressive pricing for high-quality equipment, currently the hottest mop washing in the mid-range, and a transparent disclaimer that clearly separates self-declared from verified figures. Weaknesses: navigation software less mature than Roborock's according to reviews, important accessories such as the anti-tangle brush cost extra, and a much narrower review base than the Dreame models.
Dreame (China, parent company of MOVA)
Strengths: technically the same basis as MOVA but with a more complete standard specification (detangling brush included), a higher stated obstacle clearance, a broad review base and good coverage in the press. Weaknesses: usually somewhat more expensive than the equivalent MOVA model.
ECOVACS (China)
Strengths: its own approach to mopping with the self-rinsing OZMO ROLLER, which removes dirty water continuously instead of spreading it; often the lowest street prices for a fully equipped station. Weaknesses: lower suction figures, sometimes a large gap between RRP and street price, and inconsistent customer ratings across colour variants and listings.
Roborock (China)
Strengths: regarded as the benchmark for navigation reliability and software maturity, an AdaptiLift chassis for higher thresholds and durable hardware. Weaknesses: clearly higher prices, and on the raw numbers (suction power, washing temperature) now overtaken by the Dreame family.
