How we assess
Features, controls and the practical details that matter to your choice.
Experience and documentation
A review must identify the exact model and configuration. Our own observations are described specifically, while technical information is attributed to the manufacturer. An impression of comfort is not a measurement of motor power or operating time.
Practical observations
During testing, we examine operation, adjustment, noise, handling and cleaning. The description must state what was tried, when and under what conditions. Experience with one variant is not transferred to another.
Manufacturer information
Specifications, materials and features are checked against official product pages and guides. An AI name does not document autonomous movement. Concepts and forthcoming products are labelled with their current status.
External experiences
When tests by other media are included, we identify the publisher and source. Their observations are not presented as our own.
Top 10 and scores
Our top 10 selects models by function, controls, documentation and practical limitations. We do not use stars or the term test winner without a specific basis for comparison.
Commercial relationships
Source links in this edition contain no affiliate tracking codes. Advertising, commission links and products received for testing must be labelled alongside the relevant coverage.
Keeping information current
The source check date appears on product pages. Price, stock, software and delivery can change; they are not monitored automatically.
