Battery operated vacuum?

Anyone use this to clean the bare bottom brood tanks?
I just use a net now, I was looking for something better.

i have always seen them but they dont look trustworthy.

I have tried them before and have had bad luck with them. Not much suction and they tend to fall apart. IMO don't waste your money.

I use ridged airline and run a siphon through flex airline for small stuff and a self made 1/2 inch pvc home built siphon vacum for water changes and it has a razor blade attachment to scrape the glass.

All the ones I've ever seen are worthless. When I was working in a shop I always talked people out of buying them. Anyone that did buy them always ended up coming back complaining they couldn't get it to work, or if they did get it to work it didn't do anything worthwhile. Best to just use the old fashioned siphon ;)
