These are straightforward to maintain, although Roidmi recommends replacing them every few months..

This metric is rarely provided by vacuum cleaner manufacturers though.. Are Air Watts a Useful Metric?.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..If you can’t work out what’s causing your vacuum’s suction loss, take the time to check the vacuum hose, wand, tube leading into the dust canister, and anywhere else where there might be a hidden blockage.

You may need a torch and a pair of tweezers to remove the debris..Sometimes blockages are deep inside the hose.

If this is the case, detach the hose from the vacuum, hold it straight, and shine a torch through it.If light doesn’t get through then there is a clog inside (you may also be able to see the clog.)
