If you are having troubles with vacuum cleaners breaking cheap timberland boots, why not get a Shop Vac? They are made to vacuum up nuts and bolts, so how could you possibly break it? The best part is that, the last time I checked they were only $35 - $40 (this was a few years ago timberland 3 eyes, but they shouldn't be much more now)!
I used to purchase regular upright vacuum cleaners and found that a penny or pebble would break them. In fact, I went through 2 of these type of vacuums in one year until I listened to my neighbor's advice of getting a Shop Vac.
I have the 2.25 peak horsepower Shop Vac and it is very powerful and does a better job than the vacuum cleaners I owned in the past. It will also vacuum wet stuff but I have never used it for that.
Another money- and frustration-saving benefit is that they don't take bags! All the stuff goes into the canister and when it gets full (or preferably before), you just dump it like a trash can. It does have filters that can be replaced but I have never had to replace mine; I only clean them.
Mine has a handle on top to carry it around easily and it also has an attachment holder.
I'm 5' 9" and I had to stoop a little with the attachments that came with it. I had an extra tube extender which brought it to a good height for me. The extra attachments (including the tube-extender) are sold separately for around $15 - $20.
The cord on mine is short so I have it plugged into a heavy-duty roll top timberland, 3-pronged extension cord so I can move it easily throughout the house.
I highly recommend Shop Vacs. They are so inexpensive (even if you have to buy an extension cord and extra attachments) and are so tough that you really can't go wrong.
