How we test

Overall score is based on:

Performance (60%)
Assesses concrete-cleaning performance 1 metre above ground and away from the waterblaster.

Ease of use (40%)
Assesses manoeuvring, vibration, trigger comfort and ease of cleaning with the blaster.
Penalties apply for connection issues between lance and attachments.

Noise is measured 1 metre above ground and 1 metre away from the waterblaster.

Price is based on a February 2018 survey.

Note: We changed our test method so these results replace last year's assessment. The Nilfisk Compact Series Waterblaster C120.7-6 PCAD was tested under a different assessment method in 2017. The performance score has been adjusted.
