As a result, Which? no longer recommends products that don't have replaceable batteries as Best Buys, regardless of how good they are otherwise. Its removable 400ml dust canister means there are no bags to change, so when it’s full, simply empty the contents of the canister straight into the bin and carry on cleaning.

According to our annual reliability survey, which asks owners about issues they experienced with products they bought, battery failure accounts for 52% of the reported faults with cordless hedge trimmers and 34% of the faults experienced with cordless vacuum cleaners. Interestingly, the Supervac is one of the few cleaners we have ever tested that the powered brush bar cannot be turned off and runs constantly. We are not great fans of this idea as when it comes to hard floors, particularly easily damaged surfaces such as softwood parquet, there is a danger of damage if small bits of stone or gravel get caught up in the brushes. Our reliability survey -we surveyed 7,917 Which? members in September 2019 about the appliances they have at home. We gathered data for more than 25,000 domestic appliances. Even if your battery doesn't completely die, due to the nature of lithium-ion technology, it will still gradually lose charge and you'll notice that your product doesn't last for as long as it used to. Countless cordless appliances such as vacuums, lawnmowers and pressure washers are ending up on the rubbish pile simply because the battery has failed or developed a fault.Lightweight, with a swivel head for greater manoeuvrability, the Supervac’s illuminated cleaning head makes it easy to see exactly where dirt is lurking and is especially useful for cleaning under furniture or into corners and poorly lit recesses. For each product, we asked owners if and when it developed a fault, how severe that fault was and how long their previous appliance lasted before it needed replacing. Tagged as: Coming with an array of tools, the Supervac gives that ease of cleaning to every diligent housekeeper. With a crevice tool giving access to those smaller hard to reach areas,

use, plugging straight into the mains. Useful to keep under the stairs, the Supervac also has the nifty function of a collapsible handle, folding to half the size of a standard vacuum, taking up even less space and fitting in most under counter cupboards too. These are all products where we know the battery is one of the leading causes of early failure, and where we know from survey data that you expect a Best Buy to last longer than the battery is likely to. David Winterbottom, Vax UK Managing Director, says: 'Vax has spent the last two years investing in our new ONEPWR battery technology, a replaceable lithium-ion battery unit that provides high cleaning performance with up to 45 minutes run time, and is shareable across our new range of floor-care products.' There’s no need to adjust the cleaning head as you hoover and the motorised brush head passes effortlessly from hard to carpeted surfaces without losing suction and remaining quiet.The Supervac has a dual power switch, giving you the option of turbo-charged cleaning on full power or energy-saving cleaning on the low setting. Sadly that is not the case when it gets to your carpet edges. A cursory look at the underside of the 008 reveals that the brush bar and man air-flow channel are inset a long way from the edge of the floorhead. The result is very poor edge cleaning with residual test powder showing over 1cm out from the skirting board edge. A cordless product should last just as long as the corded one it's replacing, and a battery that can't be replaced virtually guarantees that it won't. That's bad news for you, as you have to shell out for a replacement earlier than expected, and bad news for the environment, too, as it creates needless waste. In many cases, this is well before the expected end-of-life of the product. If the battery isn't replaceable, it means the whole appliance is a write-off, even if everything else is in perfect condition.

A negative pressure ventilation blower (a Smoke Ejector or Blower/ Exhauster) is positioned at an exit point to pull air away from the space, creating negative pressure to remove the heat, smoke or contaminated air. Many of these fans feature Super Vac’s patented spiral blade that creates a more concise, direct air flow, ideal for:

A positive pressure ventilation fan (or PPV) is positioned at the entry to push air into the space, creating pressure that moves heat, smoke or contaminated air out of an exit point. The Super Vac PPV fan features a chopper blade, which moves a wider mass of air, ideal for: The 732003 comes with an upright charging cradle giving the Supervac a permanent place to belong, aiding decluttering by having its own home within your home. The stand not only charges the Supervac but takes up very little space and is easy to position and We also reached out to Russell Hobbs and Morphy Richards for comment, but haven't had a response yet. Vax's newest Blade 3 and 4 cordless models, which launched on 29 January 2020, do have replaceable batteries. But some older models, including the Vax Blade 2 Max, don't.
