Review on 🌪️ Suction Power Gauge for Vacuum Cleaners, Water Lift Measurement Gauge by Joyce Swihart

I have a number of canister vacuums that I have collected over the years that are needed for lint thinning. I bought this sensor to find out which ones are powerful suction. To see how accurate it is, I tested a Festool CT26 vacuum with a water depth of 96 inches. The sensor read 98, which is only about a 2% error. The sensor was expensive but it's exactly what I wanted and it's very accurate.
