I'm looking at the same tool the VC 140-2-22, never understood why cordless backpack vacs couldn't have both more cfm and greater capacity than on offer from the likes of Makita. Just seen the specs on the the XGT models coming out, and now thinking the Hilti is the way to go. Being based in U.K. though, looks like I have to wait til autumn. If you can I'd be interested in how you get on with your new purchase, particularly interested in run time.

@@okafka5446 I’ve had it for a week. CFM is there. Sealed suction is almost there. 1.8 kpa vs 2.4 and up on corded. Louder than Festool, quieter than our American Emerson (Ridgid) and Shop Vac $100 specials. With metal tubes and a floor brush it is not great, but it works ok. Clean up without attachments it’s 95% as good as corded. Collecting dust from concrete, drywall and wood: it works well. Inlet is smaller and there’s an elbow before the bag. Thus, it sucks big stuff, but then it clogs. It’s small and manageable without wheels or a back harness. Festool/Bosch/Mirka dust ports require a different nozzle that Hilti provides. It’s easily interchangeable with two tabs on the fly. Bluetooth works but mine has a bug that requires me to cycle it on manually beforehand or I get a battery error if I just switch it on with Bluetooth (using it throughout the day afterward no issues). Build quality is fine but not to the level of Nilfisk/Starmix/Festool.

@@robertrada4783 Hey Robert, thanks so much! that's really useful information. I've got both the newer Festool Midi and the newer Starmix iPulse (mainly for large amounts of fine dust from plaster/drywall sanding). Bought into the smaller Metabo cordless extractors, but the power not there, and always felt that a back pack extractor was the way to go, particularly when working off scaffolding. Sounds like this model answers most of my needs, wish they'd thought of a design solution to the elbow before the bag though - I'm not a fan of this, always better a straight feed into the bag -like the larger Festool models - in my view. What sort of run time do you get on a 12ah battery, and what's the recharge time? Cheers Simon

@@okafka5446 I didn’t time it. With the 9 amp charger, the 12ah isn’t as fast as thirty minutes, but it’s definitely less than an hour. The trickle charge between 80% and 100% is slower than average.. Run time, non-stop. Felt like 10-20 minutes. On/off real world use… I haven’t felt like I needed a second battery. I’m doing property management, repair and installation type stuff, however. Trades, I think a pair of batteries would get you through the day. If you’re grinding concrete with it like in the promo videos….you’re gonna need a lot of batteries. FYI, Festool mini and midi go straight to the bag if you change the hose end to a straight one. With Hilti, that elbow is permanent and the part that enters the bag actually has it’s own elbow that points to the side. Not ideal for battery powered. When I was cleaning some awnings, just after receiving the Hilti, I ended up having to retrieve the Festool mini. Later on I found I had clogged it

@@okafka5446 I’ve been using the vac more. Mostly as a “pick up and go” and it seems to either be behaving better or I’m not scrutinizing it so much and getting straight to work. Having issues with over current protection when I turn it on with Bluetooth. Wish it had a hose wrap or could take my newer flexible Festool hoses. Actually I wish both. About the elbow, turns out their corded vacs are like that too.
