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.
