carpet has fine fibres in it. heat travels upwards so when it does the carpet fibres traps the heat. The thicker the carpet the better.
Vacuums can lose suction due to clogs in the hose or filter, a full dust bag or canister, a worn out motor, or a damaged seal. Regular maintenance and cleaning can help prevent loss of suction in vacuums.

Cavitation is the formation of vapor bubbles in a liquid when pressure drops below its vapor pressure, leading to intense shock waves and erosion in pumps and other components. Priming is the process of removing air from the pump and filling it with liquid to ensure proper operation and prevent cavitation.
Fitting carpet would help to reduce heat loss because the carpets fibres grip onto the air, so therefore the warm air cannot escape from your home. Also, the thicker your carpet is, the more warm air it will trap, so it will be a better insulator for you home if it is a thick carpet =)
A suction cup may stop working due to loss of pressure caused by air seeping in between the cup and the surface it is meant to stick to. Dirt or debris on either the cup or the surface can also prevent a proper seal from forming, leading to reduced suction effectiveness.
The first Dyson vacuum was invented by James Dyson in 1978. He revolutionized the vacuum industry by introducing cyclonic separation technology, which allowed for better suction power and no loss of suction due to clogging.
Loss of use is usually a coverage of the costs incurred by someone as a result of your accident. If your water heater busts and ruins your carpet you may be insured for that and get new carpet. The loss of use clause is there to pay for your downstairs neighbor to stay in a hotel while her flooded apartment is cleaned up. You didn't destroy it but there is a "loss of use".
Convection , Because it traps air , the thicker the carpet , the more heat you save
heating oil? that is considered a polluntant and generally excluded as a cause of loss
The design of bellmouth entry is to ensure that the flow is uniform over the entire intake section and the head loss induced at inlet section is minimized.
You can hire someone to do an independent evaluation of your carpet. If it was improperly installed, the only option maybe legal. If the problem is matting/staining/fiber loss then you could try and deal with the carpet mill yourself. The problem with this is, if this carpet is more then a year old, they will have to have all your documented professional cleaning receipts required under most warranties.
