The Wertheim Evolution W7301 is a cordless stick vacuum with two removable batteries, but the available documentation does not establish that “W7301B” is a separate revision. Its manual lists useful specifications and replacement-part numbers; the model is marked discontinued, and owner feedback is mixed. For anyone considering one second-hand or maintaining one already owned, the key questions are whether the model designation matches, whether a part is compatible, and what the manual actually promises.
Is the W7301B a distinct model?
The instruction manual identifies the vacuum as the Wertheim Evolution Stick Vacuum, while a retailer listing identifies it as W7301 and gives part number 14120148. A ProductReview.com.au owner uses the W7301B designation, but the available sources do not explain the “B” suffix or establish different specifications for a W7301B revision. Treat W7301B as a designation that needs verification, not proof of a distinct model.
Before ordering a battery, charger, filter, or brush component, check the label on the vacuum and compare it with the part number and compatibility details in the listing. A matching voltage alone does not establish that a battery or charger will fit or work safely.

Some owners report easy handling and useful cleaning across surfaces.

These are owner reports; they do not establish verified failure rates or show that every unit has the same problems.

If suction drops or hair collects in the airway, switch the vacuum off before inspecting or cleaning it. Follow the manual’s maintenance steps and check for blockages in the airway and floor head. If the brush head stops, the vacuum overheats, or the problem continues, stop using it and seek advice from the seller or an authorized service provider if one is available.
What warranty applies?
The manual states a two-year parts-and-labour warranty for domestic use in the country of purchase, with proof of purchase required. It excludes normal wear and tear, misuse, accidental damage, and problems connected with unauthorized repairs or non-genuine parts; accessories and consumables such as filters are excluded unless defective in manufacture. These are the manual’s stated terms, not confirmation that service is currently available.
A Kogan marketplace listing states a two-year parts warranty and a one-year battery warranty. Retailer terms can differ by seller, sale date, and location. Check the paperwork supplied with the specific purchase and current seller or manufacturer information rather than assuming either set of terms applies to every unit.
