The Dirt Devil BD20035RED was released sometime 2008 and their main selling point was the accucharge system that is smart enough to detect when the battery is full – once that happens it automatically reduces current to a trickle, just enough to maintain its charge without overheating the battery thus extending its service life.
It doesn’t use a lithium ion battery so its ability to hold its charge over the long haul is a big question mark as several consumers found out. Dirt Devil didn’t have any official number on the run time but based on consumer reviews you’ll get roughly 10 to 20 minutes of run time from a 6 hour charge.
Despite having a nickel cadmium battery, the charger is energy star rated so it does use less electricity compared to non-energy star rated chargers. It uses a bagless system but its main filter isn’t washable – it has to be replaced every 3 months to maintain efficient performance.

Based on consumer reviews, bare floor performance is satisfactory. It will do its job in cleaning small bits of dirt like bread crumbs, small seeds, dust, etc. As one consumer in Amazon pointed out “this vac REALLY picks stuff up! I am AMAZED at the amount of dog hair, crumbs, etc this thing will pull in!” It however will struggle with the larger ones, the base is low so it will not fit those larger chunks and it isn’t powerful enough to suck them in outright even if you tilt it.
Despite having a motorized brush, it struggles in cleaning thick carpet but on thinner ones will do an okay job as long as dirt fits under the low profile base and because the motorized brush uses extra power, this will cut into the already short run time so it’ll be only best used for spot cleanups. If you have deep patterned rugs, this will struggle to pick dirt up but for flat ones, it’ll do the job.
It isn’t equipped with edge cleaning bristles so it won’t pick up all of the dirt in the corners.
At over 40” long, cleaning stairs can be a little awkward but still doable.
Equipped with a motorized brush, this can remove pet hair on bare floors and carpet but hair (pet or human) tends to get stuck on the beater bar – so you’ll need to clean this regularly to maintain the performance.
This is strictly a floor vacuum – the only accessory included is the floor charger.
It takes around 6 hours to fully charge. Because it uses a smart charger (a.k.a. the Accucharge) that cuts current down when it detects that the battery is full, you can leave this on the charger without frying the battery.
This is an 8 step process that includes the following:
- Removing the dust cap.
- Taking off the filter assembly
- Separating the filter screen from the filter itself
- Cleaning both the screen and the filter
- Emptying the dirt container
- Putting the filter assembly back together
- Attaching the assembly back in the canister
- Attaching the canister on the body.
The main filter has allergen filtering capability so it can’t be washed – you’ll have to use your fingers or a brush to dislodge fine dirt trapped on it.
It will vary – the shortest was around 5 minutes, the longest around 40 minutes but in most reviews consumers reported they got between 10 to 20 minutes. Remember that this product uses a nickel cadmium battery so power delivery won’t be as consistent as it’ll be if it had a lithium ion battery. If you look at the reviews, some consumers reported power loss as early as 5 minutes of using this while others say didn’t have any performance degradation during the whole charge cycle.
It comes with a 2 year warranty on parts and motor. If the any part of the vacuum fails within the warranty, call up dirt devil and they’ll send you a replacement unit or part. Just don’t lose the power card and manufacture sticker because they’ll ask you to send those in to claim the warranty.
Not the red one you see in the picture but it’s the same model…

Around 350 people left a review in Amazon and most of them were positive. Consumers who left high ratings said that it has good enough suction that’ll pick up stuff like bread crumbs, pieces of paper, pet hair, small pet litter and small pieces of debris on hard floor, rugs and carpet though it’ll struggle with the larger ones because of the low clearance of the base. Battery life was sufficient according to the majority of reviews but there were complaints about premature failures – some a few days and some within a few months of purchase. The average run time that users got was between 10 to 20 minutes, with some complaining about losing suction as they go along while others didn’t experience this.
“Okay…fifteen days before the two year warranty was to expire…it quit charging. With a deep breath, I contacted customer service.…”
“This vacuum is perfect for what it is. I like the fact that the Accucharge won’t drain the battery like what happened on my Dustbuster…”

Interesting that a technology website would review an appliance but Doug Aamoth did it here. In his test, he was able to clean up “crumbs, coffee grounds and various crap off our linoleum floor” without much difficulty. He wasn’t able to test it on carpet though. The run time he got on his test was roughly 20 minutes.
This product would be great for small homes or apartments to clean small messes but it will struggle to pick up bigger pieces of dirt because it has a low profile and while it has decent power don’t expect deep cleaning type power. While it can pick up pet hair, you’ll have to regularly clean the brushroll because pet or human hair will get stuck in there. Suction is strong enough to use bare floor and flat thin carpet but it will struggle on thicker and uneven carpet surfaces. Because the battery is built in the unit and not removable, the long term viability of this product is questionable with several people reporting that it gave out within a year of purchase so always keep that warranty card handy just in case – it does comes with a 2-year warranty. On a side note, a couple of Amazon customers were able to get replacement units just before their warranty expired so Dirt Devil honors their warranty. For folks who can’t afford or aren’t willing to spend over a hundred dollars for a high end cordless stick vacuum like a Rowenta Delta Force or a Hoover Linx Stick Vac, this would be a good and affordable alternative, just be mindful of its limitations.
