• Highlight: Ametek-Lamb 5.7" brushed blower motor running 120V single-stage — the workhorse format used in countless commercial extractors and central vac units
• Best For: drop-in replacement for carpet extractors, central vacuum units, and bypass-cooled commercial cleaning machines
• Expert Note: single-stage Ametek configuration biases toward high airflow rather than peak water lift, which makes it the right match for extraction and dust-collection use rather than narrow-orifice deep pickup
