P-DfMA: designing to zero carbon in use

Plus, the floorhead isn’t great at cleaning carpets, but more on that later..

If the floorhead is too high, however, the head won’t clean as effectively..There is an air leak.

If air can escape before it reaches the floor tool, then the vacuum won’t be able to deliver as much suction.Check that the hose, tools, filter, canister, and other pieces of the vacuum are correctly fitted..The hose is cracked.

A crack in the hose can cause air loss, which reduces suction power.If this is the case, then you’ll probably need to purchase a new hose..

The vacuum belt is broken.

If your vacuum’s brush roll isn’t spinning at all, even after you’ve removed tangled hair, then the belt may be broken.If this happens – which it regularly did during our testing – you’ll need to pull the clumps out by hand.. We also found that the flip-down action of the bin system caused a cloud of dust to be released.

Most of the debris and dust still ended up in the bin, but it’s certainly not the best choice for people with allergies..There’s no doubt that the Shark CH950UKT is amongst the best handhelds on the market, but it’s not perfect.

One of our biggest complaints is that it’s not as easy to maintain as other handheld options.. For example, the dual foam filters need to be pulled out by hand, rather than removing them using a plastic frame.This means you need to touch the dirty filters, while also disturbing dust into the air, before you can clean them.. You also can’t remove the brush bar from the pet tool, which makes removing hair more difficult.
