The four base models in the WV range:

All WV vacs have a similar design, with a built-in handle, and are built to clean everything from windows to shower screens.

Quick comparison:
The WV6 Plus N
The WV6 Plus N gives you the greatest run-time. It has a 100-minute battery life, along with Karcher’s edge guidance system and battery indicator. It’s worth noting that the WV6 Plus N doesn’t have a removable battery, but, so if that’s important to you go for the WV5.
The WV5 Plus N
The WV5 Plus N comes with all the features of the WV2 Plus. But with an edge guidance system, LED battery light indicator, removable battery, and two suction heads.
The WV2 Plus N
The WV2 Plus N Yellow is the best value for the money. It’s cheaper than the WV5, yet still provides a 35-minute run-time and excellent performance. The WV2 Plus N provides the best balance between price and performance.
The WV1
The WV1 is the cheapest Karcher window vacuum cleaner. It has the same basic design, so it’s great for cleaning windows and tiles although the 25-minute run-time may put some people off.

1. Karcher WV6 Plus N
The Karcher WV6 Plus N is the top of the range in the Karcher window vac series.
The WV 6 Plus N offers Kärcher’s best cleaning results thanks to the new liquid silicone lip technology.
The LED charge indicator is replaced with a minute-by-minute digital display. This gives you complete control of the remaining runtime.
The WV 6 Plus N includes 280mm and 170mm exchangeable suction heads.
The battery is not removable, but it is not a problem due to the 100-minute run time on a single charge

|---|---|
| Run time | 100 mim |
| Charge time | 170 min |
| Removable battery | No |
| charge indicator | LED display |
| Nozzle width | 280mm |
| Weight | 0.76kg |
2. Karcher WV5 Plus N
A feature-packed WV vacuum cleaner is the WV5 Plus N.
It comes with all the features of the WV2 Plus N, including the two-blade sizes, 35-minute run-time, and powerful suction, with some useful extras.
One of the most important additions is the removable battery.
The WV5 is the only WV window vac to include this feature, which allows you to swap the battery and continue cleaning if you have a second battery.
The edge guidance function, which is an adjustable roller so you can get right up to the edge of frames, is a great addition.
The WV5 Plus N also has a more advanced charge indicator with a 3 LED charge level on the handle. So you can estimate how much run-time is remaining. It also does a brilliant job of cleaning windows.
If you’re looking for the best window vac and don’t mind paying a bit extra to get it, then the WV5 Plus N is the one to get.
| WV5 Plus N | |
|---|---|
| Run time | 35 min |
| Charge time | 185 min |
| Removable battery | Yes |
| charge indicator | 3 LED |

3. Karcher WV2 Plus N
The WV2 Plus N provides the best balance between performance and affordability. It’s not the cheapest. But has a 35-minute run-time, two blades, and excellent window cleaning performance.
The WV2 Plus N is great for cleaning windows, tiles, mirrors, and other surfaces around the home. It’s lightweight, includes a spray bottle kit for the cleaning solution, and is simple to empty.
The WV2 has a 35-minute run time. This equals the WV5, which is another reason why we recommend the WV2 for most people. The lithium-ion battery also means it doesn’t lose suction power as the charge runs out.
This provides the best value of any model in the WV range. If you don’t need a replaceable battery or edge guidance system, it provides better value than the WV5.
| WV2 Plus N | |
|---|---|
| Run time | 35 min |
| Charge time | 320 min |
| Removable battery | No |
| charge indicator | No |
| Nozzle width | 280mm |

4. Karcher WV1
The cheapest WV vacuum cleaner is the WV1. it has fewer features, but it provides great value for money and is perfect for smaller homes.
Like the WV2. It features the same basic design, a 100ml dirty water tank, and an LED charge display.
The 250mm cleaning head works well, while the lithium battery doesn’t lose suction as it gets low on charge.
There are several key differences between the WV1 and WV5 though. The WV1 only has a 25-minute run-time and no option to swap the battery. It also only has a single 250mm cleaning head.
The WV1 is an excellent window vac that provides great value for money. It charges faster with a full charge in 100 minutes.

|---|---|
| Run time | 25 |
| Charge time | 150 |
| Removable battery | No |
