My wife was given a Dust Buster because it didn't work. After a detailed inspection, aha! there are no Batteries.
It's not worth buying batteries, but I would spend some time at my bench whatching NCIS reruns or the news to make a power supply. . The batteries are about $60. Hmm.. after some more looking, I see this is a versapak, seems to be a standard to fit many products, I found it as low as $29 a pair for an unreviewed battery from Amazon. Now it might be worth purchasing. Maybe!
The batteries check out as 3.6v 2100mah NiMH and it uses two in series.
I ran the motor exposed with rotor attached, at 7.2 volts and the motor draws 9 amps. Does this make sense? That seems like a lot to me, but it runs fine, or so it seems. My cheap little jump leads got a little toasty during testing. I see in the reviews that battery life is one of the complaints.
If indeed 9 amps is normal, using a wall wart is not going to work. First plan foiled!
The housing is all plastic, the switch is plastic far from the contacts. No exposed metal, in fact the only metal is the contacts from the battery to the switch and the motor. So I'm thinking about a non isolated supply to run this motor.
Any Ideas for a transformerless 7.2V 10amp/12amp power supply?
Thanks, Mikek
