“The V8 Eco mode is too weak for good cleaning results whereas the max mode will drain your battery and is only meant for spot cleaning.”— @Roman-nu1om on YouTube
“We currently get about 9 minutes of use on high, which is absurdly low.”— @ArbitraryLifestyle on YouTube
“lots of issues for me with the original battery holding much of a charge. 15 to 20 minutes and dead frequently.”— @nicholaskohs5727 on YouTube
“Fed up with Dyson batteries wearing out and not lasting!”— @blakaeg on YouTube
“our v8 pretty much died after 2 years. pretty light use. it kicks everything behind it now for some reason.”— @Despite37 on YouTube
“Dont like it doesn't stay on and you have to hold it down i find it hard to use”— @kdramasweregood on YouTube
“my 3 year old V8 needed a battery and their customer service just said sorry we no longer make extra to sell, so I'd need to buy a whole new vacuum. Ended up getting a 3rd party battery on Amazon.”— castrodelavaga79 on Reddit
“We had a Dyson V8 Animal that lost suction power pretty badly over the course of about 2 years. We got it serviced and did everything they recommended but it's just a useless piece of crap. Ended up going back to a plug in Miele.”— Wind_Yer_Neck_In on Reddit
“The V8 isn't that efficient unfortunately. You need to run it on max mode too often, which significantly reduces the battery life. Using it for light cleaning on hard floors on normal mode, the battery typically lasts 10 years if you store it indoors.”— disguy2k on Reddit
“I've been using V8 for 4 years. And I started using V15 submarine today. Clearly, the V15 is much better!”— @marerubrum on YouTube
“I have tested a ton of the lower vacuums (v7, v8, ,v10) and was very unhappy with them.”— ClickIll6896 on Reddit
“the only con is the lack of the LED light on the brush, it makes a lot of difference”— @metallmad77 on YouTube
Not complaints — practical notes from owners that didn't affect the score.
“I had a V8 before and if I compare just the vacuum function, it’s basically the same. The V12 is little bit lighter and more comfortable to hold and use since no need to keep pressing the button. But the same suction power.”— szab999 on Reddit
“I recently purchased replacement batteries for both my V7 and V8 direct from Dyson. Directly from their retail website.”— Equivalent_Spread753 on Reddit
“My V8 takes 18V Makita batteries with a $20 adapter from Amazon. Not sure they make adapters for models past V8.”— swearengens_cat on Reddit
“Replace the battery. Did the same for my V8”— ehben83 on Reddit
