VACUUM CLEANERS

Suction numbers are the least honest spec in tech.

Airwatts, Pascals, Watts — every brand measures differently. We investigate real pickup performance, filtration and what consumables cost over five years.

WHAT WE INVESTIGATE

  • Real suction and airflow, not marketing units
  • Filtration class (HEPA, sealed systems)
  • Battery life vs claimed runtime
  • Weight, balance and ergonomics
  • Bin capacity and emptying hygiene
  • Consumables: filters, bags, batteries
  • Floor-head engineering for your floors

SPECS THAT ACTUALLY MATTER

RUNTIME
Claimed 60 min usually means eco mode without a powered head — real-world is often half.
FILTRATION
A fully sealed HEPA system matters for allergies; a HEPA sticker alone does not.
WEIGHT
Above 3.2 kg handheld, daily use becomes a chore. Balance matters more than total weight.
CONSUMABLES
Filters and batteries can add €150+ over five years — we count them in ownership cost.

COMMON BUYING MISTAKES

  • Comparing suction numbers across brands using different units
  • Buying for peak power you only use 2% of the time
  • Ignoring battery replacement cost and availability
  • Choosing a heavy flagship for a three-floor home

WHAT TO PRIORITIZE

  1. 01Sealed filtration if allergies matter
  2. 02Realistic runtime with the powered head
  3. 03Weight and balance for daily use
  4. 045-year consumables and battery cost

CATEGORY QUESTIONS

Cordless or corded?

Cordless wins for daily maintenance cleaning; corded still wins for deep-cleaning large carpeted homes. Many households rationally need one of each.

Are expensive vacuums actually better?

Up to a point — filtration, seals and floor-head engineering justify some premium. Beyond €700 the curve flattens sharply. Our value score shows where.

How much do filters and batteries really cost?

Typically €20–40 per filter set yearly and €60–120 per battery every 2–3 years. We include this in the 5-year ownership figure.

What does Grossmeister actually do?

It investigates an appliance before you buy it. You provide a product link, a model name, or a description of what you need — the system analyzes performance, efficiency, features, reliability signals, value and long-term ownership cost, then issues a clear verdict such as BUY IT, CONSIDER or SKIP.

Can I paste a product URL?

Yes. Choose the PRODUCT LINK tab and paste the URL from any retailer or manufacturer page. The system identifies the product and investigates it. Demo investigations use sample data where live fetching is unavailable, clearly labelled as such.

Can you detect overpriced products?

Yes. The Price & Value analysis compares the asking price against an estimated product value derived from specifications, features and category benchmarks. The result is labelled GREAT VALUE, FAIR, ABOVE MARKET, OVERPRICED or UNKNOWN.

Can you estimate ownership cost?

Yes — it's a signature feature. The Ownership Cost section combines purchase price, energy, water, maintenance and consumables over a 5-year horizon, with each component labelled as an estimate.

How does credit pricing work?

Everything is priced in credits, and packages start at 50 credits. You spend credits from your balance on the investigations you need — no subscriptions, no trials.

Is there a free trial or demo plan?

No. There are no trials, demo plans or free tiers. The entry point is a 50-credit package — this keeps the investigation queue fast and the analysis honest.

THE NEXT APPLIANCE YOU BUY — INVESTIGATE IT FIRST.

A five-minute investigation can save five years of regret.
