The Vax SlimVac Pro Plus VSV21X is a 2.3kg cordless stick vacuum with a 400ml bin, handheld conversion and two power modes. Vax claims up to 35 minutes in standard mode or 15 minutes in boost, but those are manufacturer figures—not an independent measure of everyday cleaning time. CHOICE lists performance tests for this exact model, while its numerical scores are restricted to members. The available evidence therefore supports a clear look at its specifications and ownership details, but not a verdict on how well it cleans.
What the VSV21X offers
Vax Australia lists the SlimVac Pro Plus VSV21X as a 21.6V lithium-ion cordless vacuum with a brushless motor and two modes. Its multi-surface floorhead is intended for carpet and hard floors, and the main unit converts to handheld use. Other listed features include LED headlights, a quick-release brushroll and an easy-to-empty 400ml dust bin. The vacuum weighs 2.3kg and takes five hours to charge, according to Vax’s Australian product listing.

The stated 400ml capacity is also shown as 0.4L on CHOICE’s exact-model page. CHOICE lists a measured dust collector capacity of 0.4L and a weight of 2.34kg; those figures are close to, but not identical with, Vax’s rounded specifications. CHOICE’s VSV21X listing also identifies two speed settings and a five-hour claimed charging time.

For the VSV21X specifically, Vax advertises up to 35 minutes in standard mode and up to 15 minutes in boost mode. The manufacturer says its standard-mode runtime is based on internal testing without accessories and that actual runtime varies with conditions and accessories. These are maximum claims, not promises of how long a cleaning session will last with the floorhead fitted or in boost. The product listing is the source for the model-specific figures: Vax Australia.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
The family user guide gives an “up to 37 minutes” figure for Pro/Pro Plus models, based on internal testing without accessories. Because that is a family-level maximum rather than the clearer VSV21X-specific claim, it should not be treated as a VSV21X guarantee or substituted for the 35-minute standard-mode figure. The guide also warns that actual runtime varies. A full charge takes five hours according to Vax’s VSV21X product listing and guide.
What comes in the box—and what can be added
Vax lists the vacuum, a 3-in-1 tool, a long crevice tool and a wall mount with screws as included items. The 3-in-1 attachment is intended for crevice, upholstery and dusting tasks. Vax’s product listing describes the supplied kit.

Filters, charging and care
The user guide identifies the replacement filter pack as VFT22A. Before buying, compare that designation with the marking on your vacuum and confirm that the seller lists compatibility with VSV21X; the guide covers a Pro/Pro Plus family, although it identifies VSV21X as the Pro Plus variant. The guide specifies use only with E-TEK charger model ZD012A265050AU. Consult the SlimVac Pro/Pro Plus user guide for those model-family details.
What independent evidence says about cleaning
CHOICE’s exact-model page identifies assessment categories including hard-floor pickup, ease of use, pet hair, carpet cleaning, car cleaning and noise. Its numerical performance scores are members-only on the accessible page. The listed categories show what CHOICE evaluates, but do not reveal how the VSV21X scored. No hands-on test results are available here to establish its pickup, handling, noise or real-world runtime.

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
That distinction matters if you are choosing a vacuum for a particular job. The manufacturer’s multi-surface description is not an independent finding that it performs equally well on carpet and hard floors, and the feature list cannot settle questions such as pet-hair pickup or edge cleaning. Look for accessible, like-for-like results before relying on a performance claim.

How to decide whether it fits your needs
The published facts make the VSV21X easier to assess for size, accessories and charging routine than for cleaning performance. Before buying, use these checks to match it to your home:
- Cleaning time: Compare your expected session with the up-to claims, allowing for boost use and the floorhead or tools you will attach.
- Floor types: Seek independent results for the surfaces you have, rather than assuming the multi-surface label predicts pickup on every floor.
- Bin capacity: Decide whether 400ml suits your cleaning frequency and household; the listed capacity is modest enough to be worth checking against your routine.
- Weight and handling: The listed weight is 2.3kg, while CHOICE records 2.34kg. If handheld use or carrying between floors matters, consider the weight in that use rather than relying on the stick-vacuum figure alone.
- Battery replacement: The available product information does not establish whether the battery is user-removable. Confirm this with Vax or the seller if replaceability is important to you.
- Ongoing ownership: Confirm the current warranty terms, filter compatibility and availability of any accessory head you plan to use.
These checks also make comparisons with other cordless vacuums more meaningful: compare performance on the same floor type and power setting, runtime with comparable attachments, bin size, handling weight, battery replaceability, included tools, charge time and warranty terms.
