PigletJohn mentioned a fairly bulletproof cannister vac suitable for clawing builders dust etc, anyone remember what it was or know of any other decent ones worth looking at? We have a crazy amount of small pieces of rubble and dirt and dust that needs clearing from our garden and quote fancy blitzing it quickly.
I wouldn't call the Titan tools good quality, exactly. They're made cheap to sell cheap, but they are mostly simple and sturdy. They usually have a 2-year guarantee, and are priced so that if you get two year's of use out of them, any extra is a bonus. Best to buy at the start of your project, if it goes wrong, Screwfix will exchange it. I have an idea that in the 2nd year they might send it off for repair, but that's never happened to me. AFAICT if you have a duff one it will probably go wrong quickly.
The plastic hoses and tools are flimsy, but you can get replacement sets on ebay for about a tenner. mine is an older one but I can get 30 litre white fleece bags and white filter cartridges to fit, which I think are better for dust collection than the old brown paper style. Plaster dust is very bad for clogging vacs.
Another vote for the titan...2 years in and it's still going strong as picking up all the building mess we are creating! Only downside is sometimes it chucks out a bit of dust from the bag when you first turn it on...saying that I haven't ever cleaned the filter etc
I occasionally wash out the "bucket" of mine with soapy water, and sponge down all the parts, using a paintbrush for the crevices. The pleated filter can be brushed down to remove loose dust from the pleats. When it gets really clogged with dust, you can wash it in the sink to get the dirt out, and it will last a bit longer before you need a new one. If you have two filters, one can be washed and drying while you work with the other. The paper bags delay clogging, but do not withstand water, and sometimes tear or split when you are sucking up nails or broken bricks.
it's more a domestic one, there are some heavy duty builders ones that cost £hundreds.
Builders are very clumsy and always breaking things.
The Screwfix one is a budget price, and seems to me to be durable enough for DIY work. The canister bucket and the filter cartridge are I think bigger than a Henry. It shrugs off nails, screws, socks, and broken pieces of concrete, and will suck up water from a burst pipe or a blocked drain. It's quite noisy.
