ROBOT VACUUMS

Navigation is the product. Suction is secondary.

A robot vacuum is a software product with a motor attached. We investigate mapping quality, obstacle avoidance and the ecosystem you'll live with for years.

WHAT WE INVESTIGATE

  • Navigation system (LiDAR, camera, hybrid)
  • Obstacle avoidance in real homes
  • Suction and mopping effectiveness
  • Battery life and recharge-resume
  • Mapping quality and multi-floor support
  • Dock design and self-maintenance
  • Software ecosystem and update policy
  • Consumables: bags, brushes, mop pads

SPECS THAT ACTUALLY MATTER

LIDAR
The most reliable navigation base — works in the dark and maps fast. Camera-only systems struggle at night.
DOCK
Self-empty docks add €150–300 but change the ownership experience completely.
MOPPING
Vibrating or rotating pads actually clean; static drag-cloths mostly redistribute dust.
SOFTWARE
Map quality, no-go zones and update support define the product more than hardware.

COMMON BUYING MISTAKES

  • Buying high suction with weak navigation — it cleans nowhere well
  • Ignoring consumable costs for self-empty docks
  • Expecting mopping to replace manual mopping entirely
  • Choosing camera navigation for a dark hallway-heavy home

WHAT TO PRIORITIZE

  1. 01Navigation and obstacle avoidance first
  2. 02Dock features matched to your tolerance for maintenance
  3. 03Real mopping hardware if you have hard floors
  4. 04Software ecosystem and update track record

CATEGORY QUESTIONS

Is LiDAR worth it over camera navigation?

In most homes, yes — faster mapping, works in darkness, fewer getting-stuck events. Camera systems add object recognition but need light.

Do self-empty docks justify the cost?

If you'd empty the robot daily, yes — they turn a daily chore into a monthly one. We show the convenience premium explicitly in the value analysis.

Can a robot replace my regular vacuum?

For hard floors and low-pile rugs, mostly. For stairs, sofas and deep carpet, no. The report states this clearly per model.

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.
