Air watts can be an interesting number to look at when.choosing vacuum cleaners.
– and the measure is certainly more useful than watts – but there are some limitations.. Air watts only measures the suction power of a vacuum cleaner, not dust pickup.The amount of dirt, dust, and hair a vacuum can remove isn’t just dependent on suction, but also on the floorhead and brush bar..Many manufacturers don’t publish air watts for their vacuums, as there is no obligation to do so.
This makes comparing vacuums difficult.. It’s important to check.airflow is being measured, as this affects the air watts calculation.
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.it’s important to empty the vacuum regularly to maintain your vac’s cleaning performance..
Bagged vacuums don’t need to be emptied as often as bagless models, as they have larger dust capacities.You also don’t want to waste bags unnecessarily!
Even so, it’s important to switch to a new vacuum bag whenever it’s full, particularly if you notice the suction is starting to decrease.. Bagless vacuums.should typically be emptied after each use, as they have smaller dust capacities.. Cordless vacuums.
