Question 1

What's the difference between motor watts and air watts on a vacuum?

Accepted Answer

Motor watts measure how much electricity the vacuum consumes; air watts measure actual cleaning power. A 1600 W motor does not deliver 1600 air watts — real suction performance depends on airflow design, filtration efficiency, and cyclonic separation. Always look for published air watt or airflow (m³/h) figures when comparing models, and don't assume a higher wattage motor means better cleaning.

Question 2

Is a wet & dry vacuum worth buying for home use?

Accepted Answer

For most homes, no — a wet & dry vacuum is unnecessary weight and bulk for a feature you'll rarely use. These machines are designed for workshops, garages, and construction sites where liquid spills are common. If your cleaning is limited to carpets, hard floors, and the occasional upholstery job, a standard dry cylinder or upright vacuum will serve you better and cost less to run.

Question 3

How often do vacuum bags need replacing, and what does it cost?

Accepted Answer

For regular domestic use (two to three cleans per week), most dust bags last four to six weeks before needing replacement. Annual bag costs typically run between £10 and £25 depending on the brand — Numatic bags are widely available and reasonably priced, while some proprietary bags from premium brands can cost significantly more. Bagless models avoid this cost entirely but require more frequent filter cleaning to maintain suction.

Question 4

Are Numatic (Henry) vacuums genuinely better, or just popular?

Accepted Answer

Genuinely better for most domestic and light commercial use — the reputation is earned. Numatic's cylinder vacuums are built to last, with robust motors, sensible filtration, and widely available spare parts. The Henry HVR160 and Henry Xtra HVX200 consistently outperform similarly priced rivals in long-term reliability tests. They're not the flashiest machines, but they're the ones still running after a decade of daily use in offices and homes across the UK.

Question 5

What should I look for in a vacuum for pet hair?

Accepted Answer

Prioritise strong suction (look for models with motorised brush heads), a sealed filtration system, and ideally HEPA filtration on the exhaust. Pet hair wraps around brush rolls, so a tangle-free or easy-clean brush head saves significant maintenance time. The Tower RXP30PET is specifically designed for this use case at a budget-friendly price point. For heavy shedding breeds, a bagged model is preferable — it contains dander more hygienically than bagless alternatives.

Question 6

Can I use a standard vacuum to pick up construction dust or plaster?

Accepted Answer

No — and this is one of the most common and costly mistakes buyers make. Fine construction dust, plaster, and cement particles will clog a standard domestic filter rapidly and can cause motor failure. For construction debris, you need an M-class or H-class industrial vacuum (like the Draper 86685 M-class) with appropriate filtration rated for hazardous dust. Using a domestic vacuum for this purpose also voids most manufacturer warranties.

Question 7

Which vacuum brands offer the best after-sales support in the UK in 2026?

Accepted Answer

Numatic and Miele lead on after-sales support — both maintain extensive UK spare parts networks and offer multi-year warranties as standard. Kärcher has a solid UK service network, particularly for their professional range. VAX and Hoover offer reasonable support for domestic models but can be slower on parts availability for older units. Budget brands like Yato and Einhell offer limited UK after-sales infrastructure, which is worth factoring in if longevity matters.
