It’s always interesting to keep an eye on what Gtech decides to make next!.
For a true estimate of suction power, the airflow must be measured at the cleaner head..In reality, the biggest issue is #2: most manufacturers don’t provide air watt figures for their vacuums.
Without being able to compare vacuums using the same rating, air watts becomes much less useful..Note: Air watts are measured with a clean filter and unobstructed airflow.A clogged filter greatly reduces suction power, which is why it’s important to properly maintain your filters.
We’ve written a guide for.maintaining suction power which may be useful if your vac is losing suction.
How Are Air Watts Calculated?.
There are several ways to calculate air watts, but the most common is:.This makes comparing vacuums difficult.. It’s important to check.
