- The WV6 Plus runs for up to 100 minutes on a single charge and collects dirty water in a 150ml tank.
- At about £80–£199, the WV6 Plus sits at a premium price point, and whether it's worth it depends entirely on what you need it for.
- At Ordiniq, our Handheld Car Vacuum Cleaner is built for car interiors, offering continuous wired suction and a 3-piece adapter set for tight spaces, all for £49.99 with free shipping and a 30-day money-back guarantee.
The Kärcher WV6 Plus Vacuum Cleaner: An Overview
The Kärcher WV6 Plus is a cordless window vacuum cleaner, a device that sprays a cleaning solution onto glass and then sucks the dirty liquid away before it drips or streaks. Unlike dedicated car vacuum cleaners, it is not designed to pick up crumbs, pet hair, dust, or debris from seats, floor mats, or carpeted surfaces.
The Kärcher WV6 Plus costs about £80–£199, depending on the retailer and ongoing promotions. While customer reviews are largely positive, some reviewers note that this vacuum cleaner may be on the more expensive side.

Kärcher WV6 Plus Specifications
The Kärcher WV6 is a window vacuum cleaner designed for smooth surfaces (Image source: Kärcher).
The WV6 Plus excels at removing water, cleaning solution, and grime from non-porous smooth surfaces without leaving streaks or drips.
Here’s a look at some of its key specifications:
Battery Life & Charge Time
The WV6 Plus runs for up to 100 minutes on a full charge, enough to work through an entire house's worth of windows and a couple of bathroom sessions in one go. Charging takes approximately 170 minutes from flat to full.
Dimensions & Tank Capacity
The WV6 Plus weighs 0.8kg. Its dimensions are 126 x 280 x 310mm (length x width x height), making it compact enough to store in a cupboard without taking up much space. The dirty water tank holds 150ml, enough for a full cleaning session before needing to be emptied and rinsed out.
Kärcher WV6 Plus Price & Value
The Kärcher WV6 Plus retails at about £80–£199. The value case for the WV6 Plus is strongest for homeowners who regularly deal with large glass surfaces, such as floor-to-ceiling windows, conservatories, large shower enclosures, or tiled bathrooms.
If you're cleaning windows once every few months, the price is harder to justify. But if streak-free glass is something you care about weekly, the time and effort it saves may add up fast. Keep in mind that this is a dedicated window vacuum cleaner, and as such, its functions are limited to windows alone, as it was not designed for car seats and interiors.
Kärcher WV6 Plus Reviews
Customers note that the Kärcher WV6 does a good job of cleaning windows without leaving streaks (Image source: Amazon).
The WV6 Plus consistently earns praise for its battery life. Users also highlight the streak-free finish on windows, mirrors, shower screens, and tiles, with the liquid silicone lip technology allowing uninterrupted cleaning in a single pass.
That said, the most consistent criticism centres on the two-step cleaning process. The WV6 Plus only vacuums water. It does not wash or scrub the surface, so users must first spray and wipe windows manually with the included spray bottle and microfibre pad before using the vacuum to remove the dirty water.
At its price point, some buyers questioned whether the cost is justified given the manual effort still required before the vacuum can do its job.
Best Kärcher WV6 Plus Alternatives
The WV6 Plus is excellent at what it does, but its use case is narrow. If you’re looking for a car interior vacuum or something more versatile than a window-only device, there are better tools for the job.
These alternatives cover broader cleaning needs.
1. Ordiniq's Handheld Car Vacuum Cleaner
The Ordiniq Handheld Car Vacuum Cleaner provides wired operation for uninterrupted cleaning sessions.
The Ordiniq Handheld Car Vacuum Cleaner takes on a different approach compared to the Kärcher WV6 Plus. While the Kärcher is a cordless window squeegee designed to vacuum water off smooth surfaces, the Ordiniq is a wired, handheld vacuum built specifically for car interior cleaning.
This makes Ordiniq’s Handheld Car Vacuum Cleaner the better choice for drivers who need to tackle dirt, crumbs, pet hair, and debris in seat crevices, floor mats, dashboards, and door seals rather than windows and mirrors.
Its cable delivers unlimited runtime through a standard power outlet, and the flexible hose with a 3-piece adapter set reaches into the tight spaces that window vacuums and general-purpose handhelds can't access.
At £49.99 with free shipping, the Ordiniq is both more affordable and more versatile for automotive cleaning than the Kärcher WV6 Plus. It runs at 39,000 r/min and delivers powerful continuous suction without the battery limitations that restrict the Kärcher.
2. Bosch GlassVAC Cordless Window Vacuum
The Bosch GlassVAC is a cordless window vacuum that uses Bosch's patented "Power Protection Plus" rubber coating to deliver streak-free results on glass, mirrors, tiles, and shower screens.
The unit weighs 0.7 kg, runs for approximately 30 minutes per charge (enough for about 35 windows or 105 m²), and ships with two interchangeable suction heads (266mm and 133mm) for tackling different surface sizes. A spray applicator with two microfibre cloths is included in the full kit.
The main trade-off compared to the Kärcher WV6 Plus is battery life, which makes the Bosch better suited for smaller homes or quick jobs rather than whole-house window sessions. On the positive side, the Bosch is significantly cheaper, with prices starting from around £35–£63 in the UK, depending on the retailer.
3. Leifheit Dry & Clean Window Vacuum
The Leifheit Dry & Clean is a German-made cordless window vacuum that rivals the Kärcher WV6 Plus in versatility and ease of use. It features a 28cm suction nozzle, 360-degree functionality for use in any orientation, including overhead, and an automatic standby system that only activates maximum suction when the squeegee makes contact with the surface.
The dirty water tank is removable, making it easier to empty and clean than some competitors. Leifheit's patented Click System allows the vacuum to connect to any Leifheit handle, making it useful for reaching high windows, conservatories, or skylights without a ladder.
The Leifheit sits in a similar price bracket to the Bosch GlassVAC, typically ranging from £30 to £50. However, like all battery-powered window vacuums, its 35-minute runtime falls well short of the Kärcher WV6 Plus's 100 minutes, so it's best suited for smaller cleaning sessions rather than full-property window cleans.

Frequently Asked Questions (FAQs)
Can the Kärcher WV6 Plus be used inside a car?
The Kärcher WV6 Plus can clean the interior glass surfaces of a car. However, it cannot vacuum seats, floor mats, carpeting, or any fabric or textured surface inside your vehicle. If you're looking for something to clean the entire interior of a car, you need a dedicated car vacuum, such as the Ordiniq Handheld Car Vacuum Cleaner.
How long does the Kärcher WV6 Plus battery last?
The Kärcher WV6 Plus delivers up to 100 minutes of runtime on a full charge. Charging the unit from flat takes approximately 170 minutes. Because the battery is built into the device rather than being a removable pack, you'll plug the entire unit into the mains to charge.
What is the dirty water tank capacity on the WV6 Plus?
The dirty water tank on the Kärcher WV6 Plus holds 150ml. For most cleaning sessions, you'll likely need to empty and rinse it once or twice during use. The tank detaches easily for emptying, and because all the dirty water is captured in the tank rather than dripping down the glass, the whole process stays clean and controlled.
How is the Ordiniq Handheld Car Vacuum Cleaner better than the Kärcher WV6 Plus for cleaning cars?
The Kärcher WV6 Plus is a window vacuum that cannot vacuum dirt, crumbs, pet hair, or debris from car seats, floor mats, dashboards, or door seals. On the other hand, the Ordiniq Handheld Car Vacuum is purpose-built for car interiors, delivering continuous suction through a wired motor, a flexible hose, and a 3-piece adapter set designed to reach into seat crevices, console gaps, and air vents where dirt actually collects.
