Review: Super handy, lightweight, reversible flow. Handles wet and dry as well as soil, leaves and rubble. - Wonderful handy little vacuum. Good enough to use to clean the house, clean the car, and can handle wet-and-dry without spoiling it. Ie you can clear up building rubble and mud one minute, then if you want to, you can clean out your car. Each battery charge lasts ages and ages, and fully interchangeable with other WORX tools, (we have about 10 batteries for these things, and they are all interchangeable). The battery space on this vac is big enough for the 4Ah batteries as well as the normal ones, and it also has some handy nozzles which fit in the battery space as well, so you don't lose them, and there is a handy carrying handle. As a last plus, you can reverse the suction, so it becomes a blower. I found after repairing a wall which had been filled with polystyrene balls, that they went everywhere and I really struggled to pick them up. So I put it on blow, and it worked a treat. Also can easily pick up leaves etc on the patio. I am lucky enough to have a Tesla car, which has an unlimited service interval; I have just gone over 105,000 miles, and had to top up the coolant on the battery system - ie its first ever service, which they did on my driveway - which meant removing the (enormous) air filter. The service only cost £29.00, (twenty nine pounds)!!! My Mercedes I had before never cost less than £1k for a service. Tbh after 105,000 miles, I should really have replaced the air filter - but I just gave it a go-over with this little beauty, and it sucked all the grime of 4x round the world, so they put the old one back in as good as new; although the filters in these things are so good, it smells no sweeter than it did before - however is probably good for another 105k miles! Last thing - we have crazy paving on our patio, which always ends up infested with weeds because soil gathers between the stones. On a dry day, I tried out of interest vacuuming between the stones - blow me down, it sucked up every jot of soil between the stones, and hey presto no more weeds - just lovely! Completely recommend this thing, and every time I think I've used it for every handy job - another really useful application comes up for it.
Review: Fantastic suck and blow. - Brilliant worx sucker/blower. Used for car, but even better that I can blow off the water when washing outside the car, even trying it with snow to blow snow off car or garden path, I have loads of worx gear so batteries are just swapped. Batteries last around 7>8mins. Even used on stairs in house. Brilliant for car cleaning inside /outside and work shed..My neighbour has also bought one too after seeing my new pice of worx kit.

## Questions & Answers

**Q: Where can I get additional filters?**
A: Hello, spare filters will be available soon under product code WA6078. Hope this helps.

**Q: Could this work as a garden blow/vac?    Mainly leaves,maybe damp ones, I reckon the b/v they have is too big for me/my garden…**
A: It would be very slow.  Any decent sized leaves will block up the hose. It’s only 32mm dia.

**Q: product description contradicts itself! It says “included components battery”, “batteries included: no” & “what’s in the box: battery”. so what is it?**
A: The .9 at the end of the descriptive title indicates that it is the bare unit only. The Bty. and charger is available separately. 
You can buy the unit complete with charger and Bty. if you wish.
Worx do this so that people who have several of their “Power Share” tools do not have to always pay for bty’s. and chargers, when they already have them.
Hope this sorts the problem for you. 
By the way all Worx products are superb.

**Q: Are the replacement filters for wet/dry vacuum cleaner available now?**
A: Yes

### ⭐⭐⭐⭐ Good, but it eats batteries.. they overheat! I have BEEF!
*by P***L on 7 June 2023*

I'm a Gas Engineer and I'd recommend having an 'aqua vac' in your arsenal any day of the week. Whilst training I'd used larger mains operated ones.. but these are typically bulky, with hoses everywhere, cables... plugs to find etc. You can't just quickly grab them, it's an ordeal! I already have Worx tools that I'm happy with, I saw this and thought yeah, quick and compact.. press a button and suck! I knew I'd be limited by the water capacity.. but this didn't bother me too much, though I do wish there was a larger capacity version. I've been using it frequently for about 6 months now. So what's the beef you ask? Well, there are three beefs - Beef 1 - The battery! You can't vacuum your car out fully before the battery overheats, not runs out of charge, overheats! I've had a similar problem when sucking water out of a radiator and when doing a boiler repair. I initially thought oh, it's full (and sometimes it is), or the battery has died, but most of the time the battery has overheated. Now, sure, just change the battery, let the other one cool... it's just annoying though and happens too quickly, normally at the worse time. Now, there is an Eco mode.. but I normally need maximum suckage, let's face it, battery vacuums aren't known for their power anyway. What makes this problem worse (I'd assume) is that they've covered the battery with a plastic lid. I'm planning on drilling holes in mine to let the hot air out, I don't know if it well make any difference.. really it could use a fan blowing air over it. Maybe they could have had two battery connections so it could alternate when one got too hot. The only other time I've had this overheating issue with Worx tool, is with the angle grinder, but that I can understand and it only happened once. Saying all of this, if you're only using it for a couple of minutes to suck up some crumbs or a spillage, you'll be fine. Beef 2 - Tools. More specifically the tool on the side. When I saw this in the photos before buying it, I thought there's no way that's going to stay on there long! You guessed it; falls off all the time! ALL THE TIME!!! I've left it off permanently now. It's just annoying, as a simple plastic clip would have done the job to hold it properly. Beef 2.5 is that it should come with a brush tool. I knew it didn't when I bought it, but it should! I've adapted one from my old Shark, which sort of works (I'm lying, it doesn't really...but it's all I have). The crevice tool is kept toasty warm inside the battery compartment. Beef 3 - Screws. So it can suck water up, and it does it well. So if you were designing this, would you use steel screws inside (where the water is stored)? If you did, you'd at least cover these with a rubber plug or something right? Sadly there are steel screws inside, and my screws are already rusting. I've covered mine in some grease to help prevent this. Overall though, when it does the job, it does it well, quickly and efficiently. There's been instances where suddenly water has come out of nowhere and this has saved the day. The fact that it doesn't take up a lot of room, it's quick to grab and ready to go when you need it, is great! It looks pleasing and has a quality feel to it, the hose for example feels like it will last forever. I just feel it could and should be improved to fix the beefs. Mainly the battery issue, that's the biggest beef of them all. Oh, it also blows! I've never needed to blow anything, but.. it's good to know I have the option should I need to. So.. would I buy this again you ask, knowing what I know now? As I already had Worx tools and batteries, it made sense at the time. If I hadn't, then I probably would have looked at the competition more, researched more. There are cheaper brands with bigger capacities, more tools etc. I can't obviously comment on the battery usage. I suppose the benefits outweigh the annoyances and limitations that the 3 beefs bring. I've adapted to using it, taking two batteries onto a job etc. However, if in the future it dies and needs replacing, I will do more research before making my purchase. I award this 3.5 stars.
