Upright or cylinder: start with your floors and stairs
Which? says uprights are good for covering large floor areas, particularly carpets, and are generally better at getting hair and fluff out of carpets, but are harder to use on stairs, in tight spaces and under low furniture. Cylinders have a long flexible hose that usually makes stairs easier and, on average, reach further from the socket, but they can be harder to push over thick carpet, particularly without a turbo brush.
Some models narrow the gap. The Vax Air Stretch Pet Max adds a stretch hose to an upright, and the Shark NZ801UKT in our listing has a Powered Lift-Away that converts it into a portable vacuum. Neither replaces a cylinder on every staircase, and we have not tested either on stairs.
Bagged or bagless
Which? says bagged models tend to have a larger capacity, while bagless models have a smaller dust capacity and need emptying more often. It found that both can lose suction as the bag or container fills, and that bagless models still released much more dust into the room when emptied than bagged ones. Bagged models mean an ongoing cost, because you have to remember to buy bags, and Which? says branded bags often have extra filtration while cheaper ones usually do not.
The examples span the range: Numatic’s 9 L drum, the 4.0 l Bosch bag and the 3.5 L SEBO bag, against the Hoover’s 2 L bin and the Vax’s 1.5 L bin. Think about the chore you mind less. Do you want to buy and change bags, or tip out a bin more often?
Cable, hose and reach are three different numbers
Which? says corded cables run from about six metres to more than fifteen, and that this makes a big difference. A cable only tells you how far the machine can stand from the socket. Reach adds the hose and any tubes, and makers define it differently. Vax counts a 13 m cable plus a 3.6 m total stretch hose as up to 17 m, Bosch gives a 10 m operating radius with a 7 m cable and Hoover an 11.5 m working radius with a 6.5 m cord for the H-POWER.
Numatic lists a 10 m cable and a 26.4 m ‘cleaning range’ for the Henry, and SEBO an 11 m ‘cleaning range’, and neither page defines the term, so we do not compare them. Measure the distance from your socket to the furthest corner you clean, then compare cable and hose, not the headline reach.
Carpets and hard floors
What matters is the floor head and whether it can be adjusted. SEBO’s brush roller switches off with a foot button for delicate floors, and the Hoover Breeze Evo Pets in our listing has a brush bar adjustable for different floors and a carpet height selector. The Bosch BGB41HYGGB lists a hard floor nozzle among its six, while the Bosch BGL38BA3GB lists crevice, upholstery, universal and turbo nozzles and no hard floor nozzle. Hoover describes the H-POWER’s combi floorhead as usable on hard floors, rugs and carpets.
Which? says most vacuums ship with a combination floorhead that works on all floor types, some can be adjusted when switching between carpet and hard floor, and some premium models adjust themselves. None of the pages we read measures how well a floor head cleans, and we have not tested any.
Pet hair
Which? says floor tools with spinning brush bars or powered turbo brushes can be handy for picking up pet hair from carpets, and that a mini turbo tool helps on sofas and stairs. The Vax Air Stretch Pet Max and Pick Up Pet list turbo tools, the Hoover H-POWER and H-ENERGY list pet turbo tools, the Hoover Breeze Evo Pets lists a pet hair remover and the Shark NZ801UKT a Pet Power Brush.
Numatic’s Henry page names no pet tool. A tool’s name is not a result, and what any of them does to real pet hair is something only testing can show.
Filters and the word HEPA
Makers use different filter words, and a washable filter is not the same as a HEPA filter. Hoover’s H-POWER page says washable HEPA H13, Bosch’s BGL38BA3GB says HEPA hygienic filter, Bosch’s BGB41HYGGB says UltraAllergy hygienic filter, Hoover’s H-ENERGY page says washable EPA and SEBO uses the term S-Class. Numatic lists a Tritex filter with HepaFlo bags, where HepaFlo is the name of the bag.
Amazon.co.uk titles do not always match. The titles for the BGB41HYGGB and the H-ENERGY say HEPA where the makers’ pages do not, so the cards follow the makers. Allergy UK recommends a vacuum with a HEPA filter that does not blow out dust, and says measures against house dust mite lower but do not remove the allergens. We make no claim that any of these vacuums removes allergens, bacteria or viruses.
Weight, noise and storage
The makers’ weights in our listing run from 3.92 kg for the Hoover H-ENERGY cleaner alone to 7.3 kg for the Henry on its data sheet, with the Bosch and Hoover cylinders at about 4.5 kg and the uprights at 4.9 to 6.8 kg. Figures are not measured the same way: Bosch and Hoover give a cleaner-only weight and a heavier net or gross weight, so check which one is printed.
Noise is printed for some machines and not others, and makers measure it in different ways. Bosch gives 75 dB(A) for the BGB41HYGGB and 79 dB(A) for the BGL38BA3GB, and Hoover 72 dBA for the H-ENERGY, but we do not rank them on it. An upright needs floor space and a cylinder a cupboard, so measure where it will live.
Bags and replacement parts
A bagged vacuum needs a supply of the right bag. Numatic’s data sheet lists NVM-1CH bags in packs of ten for the Henry and its page calls them HepaFlo bags, Bosch names an AirFresh dustbag for the BGB41HYGGB, SEBO a sealable Ultra-Bag and Hoover’s H-ENERGY page refers to EPA bags. Check that the exact bag is sold and what it is called before you buy, because Which? says bags are an ongoing cost.
Filters need care too. Washable filters are cleaned as the maker’s manual says, and a bagless machine needs its bin and filter cleaning more often. Follow the manual for the exact model; we do not give a cleaning interval that a maker has not printed.
Common buying mistakes
The first mistake is buying on wattage. A rating is the electrical power a motor is rated for, not a measure of how much dirt reaches the bin, and Numatic’s 620 W, SEBO’s 700 W plus 175 W, Bosch’s 600 W and Hoover’s 850 W are not directly comparable performance figures. The second is trusting a headline range, such as a ‘cleaning range’ nobody defines. The third is taking a listing title as the specification: the Amazon.co.uk title for the BGB41HYGGB says HEPA and 1.5L where Bosch says UltraAllergy and 4.0 l.
A fourth is forgetting that Amazon.co.uk often carries several listings for one machine, as with the Henry, so match the model number, not just the name. The last is treating a manufacturer’s filtration percentage as a result. Hoover’s 99.9% and SEBO’s 99.97% are the makers’ statements, with no test conditions on the pages.
