Frequently Asked Questions.Why is My Henry Making a High Pitched Noise?.

A high pitched noise indicates that your Henry’s motor is being overworked.This is often because the bag is full, so try emptying the Henry to see if this fixes the issue..If you’ve emptied the bag and are still hearing the noise, then there may be a. blockage in either the hose.

or the floor tool.. Start by checking either ends of the hose to see if there is an obvious blockage.You may be able to pull out the blockage using your hand or a non-sharp tool (be careful not to damage the hose.).

If you can’t see a visible blockage, squeeze along the hose to try and find it.

Once you’ve located the blockage, try bending and squeezing the hose around this area.However, these are often very expensive vacuums (some cost £500+).

Cheaper cordless vacuums often struggle with carpets and removing dirt between floorboards – especially compared with corded models in the same price range..Keep in mind that there are still plenty of poor-quality corded upright and cylinder vacuums on the market.

Just because these types are more powerful on average doesn’t mean that every model will outperform cordless vacs.. Will Cordless Vacuums Catch Up in the Future?.While corded vacuum cleaners are more powerful than cordless, the gap has already narrowed a lot over the last decade.
