The Karcher WV2 Plus Reviewed

Karcher WV2 Plus Window VacThe model we reviewed in detail was the Karcher WV2 Plus model. The Karcher window vac range currently has 3 models and the WV2 Plus sits in the middle of this range. The RRP of this model is £60 (we paid £50 from Amazon). The WV1 is £10 cheaper but is the old model and does not come with the spray bottle.

The range topping WV5 Premium is £30 more expensive and for this you get an additional smaller suction nozzle and the battery can be removed and replaced with a spare charged battery, although the charging station and additional battery cost nearly £50.

So, what can the Karcher window vac be used for? The main use is for cleaning windows but it can also be used for cleaning shower doors and removing condensation from windows. Another use is cleaning up liquid spills.

What’s in the box?
Karcher WV2 Plus Cleaning ToolThe WV2 Plus is supplied with the main vac unit, a 11″ (28cm) wide suction blade head, a spray bottle/microfibre cleaning head tool, charger plug and a small sample sachet of cleaning solution. The suction blade is really easy to click into the body and overall the unit is quite light and easy to handle. There is an easy to reach power button with LED indicator light on the back of the main unit.

The water collection bottle can be easily emptied by undoing the rubber bung and the whole bottle unit can be removed for cleaning (although you have to detach the vac head to do this).

We found that the spray bottle/cleaning head tool was a little bit fiddly to put together and on the first attempt we did not screw the trigger head on correctly and ended up with a wet floor. The water bottle also seems to have a small capacity but we managed okay on our small window cleaning test. The cleaning cloth is attached by Velcro so can easily be removed for washing (in a washing machine).

Test no.1: Window cleaning
Karcher WV2 Plus_Wndow leaningAfter fully charging the WV2 Plus for around 2 hours we set to work cleaning some windows (a set of small French doors). It took around 2 minutes to clean the windows which involved first spraying with the cleaning tool then going over a couple of times with the vac.

The spray tool is very to use and the vac did a good job of cleaning up the water first time and we only had to re-do certain areas. We only used washing up liquid in the cleaning bottle but overall the windows looked clean and streak free when we’d finished.

We also found that the window vac is relatively quiet to use as the motor does not generate too much noise.

Test no.2: Removing water from a shower door
Karcher WV2 Plus_Shower screen cleaningHaving had the Karcher Window vac for a couple of weeks now we’ve found that one of its most useful applications is in the bathroom. It gets put to use after the shower has been used for removing water from the shower door and tiles and also removing condensation from the large mirror we have above the sink.

In the quick shower door cleaning test it took well under 1 minute to remove all the water from the door. Previously we would have used a cloth to do this, so using the WV2 Plus was much easier.

Test No.3: Cleaning up spills
Karcher WV2 Plus_Floor spill cleaningAnother good use for the Karcher Window Vac is cleaning up liquid spills from hard floor surfaces, such as laminate, tiles or hardwood flooring. For this test we just used water on a laminate/tile floor surface and the window vac handled this with ease. We were surprised to find that the floor was almost dry to the touch after use.

If you were to clean up other liquids, such as milk for example, then you would need to remove the water collection bottle from the main unit to give the bottle a good rinse out.

The Karcher WV2 Plus Review: In summary

Pros:

  • Wide variety of uses around the home
  • Lightweight to use
  • Wide suction head makes using easier & quicker
  • Reasonably quiet
  • Easy to empty the water container
  • Cleaning/spray tool works well
  • Not too expensive if bought on offer (we have seen prices as low as £40)

Cons:

  • Water container and spray bottle capacity could be larger
  • Quite a big unit to store
  • Only comes with the one size blade attachment

Our verdict
Karcher have a strategy of offering “basic” products and then “premium” versions with extra (admittedly useful) accessories; this is common on their pressure washer range as well as their window vac range.

The WV2 Plus and WV5 Premium window vac models pretty much have the same base unit, the only difference being that the WV5 Premium has a removable rechargeable battery with extra running time. The WV1 uses the older, bulkier and heavier, base unit.

The difference is mainly in the accessories. We would honestly avoid the base WV1 model as it only comes with as standard wide nozzle and does without the cleaning tool (plus it’s the old base unit).  The best bet is the WV2 Plus that we tested as this includes the cleaning trigger bottle & pad.

The WV5 Premium does have its longer running time and an additional smaller suction nozzle but in everyday situations these are features you can easily leave without, especially as its around £20 more expensive that the WV2 Plus.

Our recommendation: Go for the WV2 Plus as often this will only cost slightly more than the base WV1 model but is the more modern version and includes the very useful cleaning tool.

Karcher Window Vac Accessories

There are several accessories available for the Karcher window vac including replacement pads, belt holders, cleaning liquid and extra battery chargers.

However, perhaps the most useful accessory is the extension pole set for cleaning windows.

The set consist of 2 extending poles; one for the window vac and a separate one that has a washable cleaning head attachment. Each pole is 1.2 metres in length but can be extended to 1.9 metres. Your Karcher window vac can be securely mounted on the base plate and attached with the rubber strap.

Karcher Window Vac reviews: which one is the best?

Karcher window vac range

Karcher window vac rangeIf you are looking for a window vac, you can’t go far wrong with the Karcher range. Karcher have three models/kits to choose from; the entry (and cheapest) WV2, mid-range WV2 Premium and range-topping WV5 Premium. These models replace the previous WV50, WV60 and WV70 window vacs, with retail prices ranging from £60 to £100 (although it’s worth shopping around for the best prices).

The 3 models basically consist of the same window vacuum but include different levels of accessories (see table below).

Features

Karcher window vac window cleaningThe Karcher window vacuum is a cordless, hand held cleaner. It is lightweight (700g) so very easy for anyone to use. It comes with a rechargeable lithium-ion battery and when fully charged it covers approximately a 75m2 (105m2 on the WV5) of window area. It doesn’t drip any water onto the cleaned surface and leaves a streak free finish.  The on/off button is in an easy accessible place but this is also one of its negatives as it can be easily turned off whilst using the unit. This is all backed up by Karcher’s  2 year guarantee.

 

What’s it like to use?

The vac is incredibly simple to use. Start by spraying the cleaning fluid on the area you need to clean, wipe down with a soft cloth then vacuum the excess liquid off with either the narrow or wide heads. The WV2 only has the wide head attachment and in our opinion the narrow suction head is a necessity for those trickier corners to reach, especially on smaller windows styles such as Georgian.

Once finished the vac is easily emptied by pulling out the rubber lug and tipping the water out of the unit.

 

The pros and cons

Karcher window vac cleaning spillsIf you read most Karcher Window Vac reviews you will see that the Window Vac is a great little piece of kit that can clean almost any smooth surface. Heavy condensation can be removed quickly from windows. Spillages on carpets and hard floors can be sucked up easily avoiding the usual mopping. Bathroom tiles and shower screens can be cleaned with ease leaving a streak free finish. Conservatories can be cleaned inside and out saving a fortune on commercial window cleaners.

 

If mobility is an issue the Karcher Vac is relatively easy to use because of its lightness (700g); this is not a big and heavy cleaner.  There is a battery indicator which shows when the unit is going to run out, this is useful as the window vac  can sometimes require recharging during longer cleaning sessions. However, if you ensure thd e battery is fully charged before starting to clean then most jobs can be done on a single charge. You also have to consider that there is a trade-off between battery life and weight; a larger battery would only make the unit heavier.!

 

So what are the differences between the 3 models?

Karcher have a strategy of offering “basic” products and then “premium” versions with extra (admittedly useful) accessories; this is common on their pressure washer range as well as their window vac range.

All window vac models pretty much have the same base unit, the only difference being that the WV5 Premium has a removable rechargeable battery with extra running time. The difference is mainly in the accessories. We would honestly avoid the base WV2 model as it only comes with as standard wide nozzle. The best bet is the WV2 Premium as this includes the cleaning trigger bottle & pad plus the additional narrow nozzle for cleaning jobs where space is tighter.

The WV5 Premium does have its longer running time a “distance spacer” nozzle but in everyday situations these are features you can easily leave without.

Our recommendation: Go for the WV2 Premium as often this will only cost slightly more than the base WV2 model but has those useful extra accessories.
