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.

Recommendation by household Smaller flat, mostly hard floors: 8,000–15,000 Pa is usually plenty. Several pets or medium-pile carpet: aim for 18,000–20,000 Pa. Lots of long-pile carpet: here a good brush and a carpet boost mode help more than the Pascal figure – look for those rather than the nominal number.

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.

When is hotter washing worth it? Kitchen and bathroom in the cleaning area, allergy sufferers or small children in the household, pets, or a desire for several cleaning runs per day: then 100 °C plus fast drying is a genuine argument. For purely dry living spaces with occasional mopping, the class standard is enough.

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.

Which one for whom? Kitchen, children, pets, lots of wet dirt: a mop roller with fresh-water circulation. Mostly dry floors with the occasional dried-on stain: rotating pads with high contact pressure. Lots of corners and skirting boards: definitely choose a model with an extendable mop or extendable side brush.

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.

Practical consequence Always include the price of the anti-tangle brush when comparing. Otherwise you are comparing a fully equipped machine against one that is still missing the decisive component – and the apparently cheaper candidate ends up costing more.

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:

ClaimSource according to the manufacturerReliability
99.9999 % sterilisation rateTÜV Rheinland, report no. 704012511339-00Externally verified

120,000 rpm motor speedInternal lab testsSelf-declared
99.99 % dirt and hair pick-upInternal lab testsSelf-declared
99.9 % pet and waste detectionIn-house lab testsSelf-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.

FAQ: buying a robot vacuum

For normal households with hard floors and short-pile carpet, 5,000 to 8,000 Pa is usually enough in practice. Figures like the 30,000 Pa of the MOVA P70 Pro Ultra mainly matter for households with pet hair, long-pile carpet or very large floor areas. The important context: there is no standardised measurement method for suction power, so every manufacturer measures using its own procedure. That is precisely why the P70 Pro Ultra scored 98.3 out of 100 points on hard floors in practical measurements, but only 68.71 on high-pile carpet – the Pascal figure alone says little about the result on carpet.
Higher washing temperatures remove grease and dried-on dirt from the mop textile more effectively and reduce the bacterial load more noticeably. On the MOVA P70 Pro Ultra the 100 °C figure is the surface temperature of the PTC heating element on the washboard, not the temperature of the wash water – an important distinction that manufacturers rarely make clear in their advertising. On this model, though, the practical evidence exists: TÜV Rheinland has confirmed a germ reduction of 99.9999 % against four types of pathogen (report no. 704012511339-00). If you mainly use the robot in the kitchen and bathroom, or have allergy sufferers in the household, you will notice the benefit. For purely dry living spaces it is more a comfort argument than a necessity.
Considerably more important than most buyers expect. Damp mops left lying in the station for hours develop odour – and that ends up on your floor during the next cleaning run. Models with a two to four hour drying cycle at 40 to 50 °C take correspondingly long before the station is ready again. The MOVA P70 Pro Ultra dries with 70 °C hot air in around an hour, clearly above the class average. If you want the robot to run several times a day, that is a genuinely relevant advantage.
LDS and dToF laser systems emit light pulses and calculate a precise room map from the time of flight – which works in complete darkness too. Pure camera navigation needs ambient light but is well suited to object recognition. Most current models, including the MOVA P70 Pro Ultra, combine both: an LDS laser for the map and an AI camera for obstacles. What matters, though, is not the hardware but the software: the P70 Pro Ultra recognises more than 280 object types according to the manufacturer, yet does not always avoid them reliably according to reviews. Detection and reaction are two different things.
Both have clear strengths. Two rotating pads, as on the MOVA P70 Pro Ultra at 260 rpm with 12 N of contact pressure, scrub vigorously and deal well with dried-on stains. Their drawback: once a pad has absorbed a lot of wet dirt it keeps spreading it until it is washed again – which is why reviewers report frequent trips back to the station. A self-rinsing mop roller such as the ECOVACS OZMO ROLLER is continuously flushed with fresh water and removes dirty water as it goes, but works with less concentrated pressure. For households with frequent wet dirt (kitchen, children, pets) the roller has more going for it; for stubborn dry stains, the pads do.
Long hair wraps around the main brush and the wheel axles and then has to be cut away by hand – the most common source of frustration in day-to-day robot vacuum use. Anti-tangle brushes have comb teeth or cutting edges that release hair mechanically. When buying, check carefully whether this system is included as standard: MOVA advertises a triple anti-tangle system on the P70 Pro Ultra but notes in its disclaimer that the CleanChop brush required for it is available separately. The corporate sibling Dreame L50s Pro Ultra and even the older MOVA P50 Pro Ultra, by contrast, include their detangling brush as standard. If you have pets, settle this point before comparing prices.
From the small print. Reputable manufacturers list where each figure comes from in their disclaimer. MOVA, for example, states: "30,000 Pa, 120,000 rpm, 99.99 %: based on internal lab tests" – in other words, its own measurements. For two claims, however, MOVA names an external body: the sterilisation rate of 99.9999 % (TÜV Rheinland, with a report number) and the 100 % coverage of the edge cleaning (TÜV SÜD). Those two figures are dependable; the rest is marketing. As a rule of thumb: if a testing body is named along with a report number, the claim is verifiable – if that is missing, it is a self-declared figure.
Almost always just the interval until the dust bag in the station needs replacing – not that no care is required at all. You still have to refill clean water (4.0 l on the P70 Pro Ultra), empty waste water (3.5 l) and occasionally free the brushes of hair. The washboard itself and its filter also need regular cleaning, otherwise washing performance suffers. Realistically, expect a brief task once a week and a more thorough clean once a month.
More than most people expect. The station of the MOVA P70 Pro Ultra measures 420 × 458 × 470 mm – roughly the size of a small bedside table. Add the access ramp, which needs space in front of it, plus a few centimetres of clearance at the sides so the robot can dock cleanly. Plan realistically for a free footprint of around 50 × 60 cm plus manoeuvring room. Important: the station needs a power socket and should stand on a hard floor rather than carpet so that any drips can be wiped up.
That depends on what bothers you. The raw numbers argue against it: the Qrevo Curv costs around €768 and states 18,500 Pa and 75 °C mop washing – the MOVA P70 Pro Ultra delivers 30,000 Pa and 100 °C for more than €200 less. What you pay for with the Roborock is mechanics and software maturity: the AdaptiLift chassis for higher door thresholds and navigation regarded as the most reliable on the market. That is exactly where the MOVA has its documented weak spot. If your floor plan has lots of tight spots and thresholds, or if unexplained pauses and ignored no-go zones would genuinely annoy you, the premium is well spent. For an open floor plan with mostly hard floors, it is not.
