The Wertheim Evolution W7301 is a cordless stick vacuum with two removable batteries, but available documentation does not confirm that “W7301B” is a separate revision. Its manual lists up to 25 minutes of standard-mode use per battery, a 0.6-litre bin and a 2.7kg weight with the rod and powerhead. The model is marked discontinued on ProductReview.com.au, and owner feedback is mixed, so the most useful review is a look at what the specifications, user reports and parts documentation can—and cannot—tell you.
Is W7301B a distinct model?
The instruction manual identifies the appliance as the Wertheim Evolution Stick Vacuum and documents model W7301 specifications. A retailer listing also identifies W7301, with part number 14120148. ProductReview.com.au includes an owner reference to W7301B, but the available sources do not explain the “B” suffix or establish a separate W7301B specification set. Treat the model as the W7301 unless the label on your unit or its paperwork says otherwise.

That distinction matters most when sourcing batteries, filters, chargers or a brush assembly: match a replacement to the exact model and part number, not just the family name.

What the runtime figures mean
“Up to” is a ceiling stated in product documentation, not a promise of the same runtime in every home. Actual use depends on operating mode and conditions. The available sources do not provide an independent laboratory runtime test, so the figures are best used as manufacturer guidance when judging whether the vacuum’s battery setup may suit your cleaning routine.
How owners rate it
On 7 October 2026, ProductReview.com.au displayed a rating of 3.0/5 from 160 reviews: 46% positive, 13% neutral and 41% negative. These figures describe reviews on that platform at that time. They are a self-selected user-review aggregate, not a representative consumer survey or a controlled performance test. The same platform marks the product discontinued.

Written feedback is varied. Some owners praise easy handling and use across different surfaces. Negative reports include battery runtime declining, hair or debris collecting in the airway, reduced suction, overheating, interruptions at the brush head and durability concerns. These are individual accounts; they do not establish failure rates or prove that every unit has those problems.

Where to look for parts and filters

For a search, use the exact model and item—for example, “Wertheim W7301 replacement battery pack”—then verify that the listing explicitly confirms compatibility with your unit or the manual’s part number. A matching voltage alone does not establish that a battery or charger will fit or work safely. Apply the same model-level check to filters and the agitator bar.
The manual’s filter-set entry identifies a replacement item, but the available documentation cited here does not establish its precise location in the vacuum or give a current parts-sales route. Consult the manual for your unit and check seller or manufacturer information before ordering.

Cleaning limits and basic care
The manual specifies dry domestic cleaning: dirt and dust on household carpets, flooring, walls and fabrics. It warns against industrial use and against collecting construction debris such as cement or fibreglass, as well as excessive or frequent sand. Those limits matter because using the vacuum for unsuitable material can damage it and may affect warranty coverage.

- Use the supplied charger, as directed in the manual.
- If suction drops or the brush head stops, check for hair or debris obstructing the airflow or brush assembly, following the manual’s maintenance instructions before resuming use.
Warranty: check the terms for your purchase
The manual states a two-year parts-and-labour warranty for domestic use, valid in the country of purchase, with proof of purchase required. It excludes normal wear and tear, misuse, accidental damage, and problems related to unauthorized repairs or non-genuine parts. It also says accessories and consumables such as filters are not covered unless defective in manufacture. These are the manual’s terms, not confirmation that service is still available today.

A Kogan marketplace listing states a two-year parts warranty and a one-year battery warranty. Retailer terms can vary by seller, sale date and location, so use the warranty paperwork for your specific purchase and check current information with the seller or manufacturer. The available sources do not establish a current service route.
Who should consider this vacuum?
The W7301’s documented removable-battery design and accessory set may appeal to an owner looking for a cordless unit for dry household cleaning. The manual’s runtime figures, bin size and weight help set expectations, but they do not answer how well a particular unit will handle carpet, hair or a larger home. Owner reports point to both useful everyday experiences and problems, while the discontinued status makes parts verification especially important.
If you already own one, confirm the exact model and part numbers before buying replacements, and use the manual’s cleaning limits and charging instructions. If you are considering a used unit, verify that the batteries, charger, powerhead and relevant accessories are present and working, and establish whether replacement parts are available before relying on it as your only vacuum.
