Cordless 56V blower. I tried several and bought the most powerful one available. Works great.

I've had this tool for 9 days. It is superior to every other cordless machine on the market. So far, I have used it to clean 3 roofs, to clean out a very awkward space between a lumber storage shed and a rock wall, blow leaves on a large parking lot and to blow insulation and filth from an attic to a dump bin. I paid $200 for it and it was central to the completion of about $700 worth of work.

It has lots of power and it can be dialed down to a very low speed for confined spaces. A gas machine would have been useless in the attic and would have made a smokey stench between the building and the rocks.

Batteries are interchangeable with the chainsaw and hedge cutter. It can work on low for about an hour. On high it goes for about 15 minutes. I average about 1/2 an hour between battery changes.

My friend had some very dirty gravel under her porch. I used the blower to send all of the rotten leaf material and needles into the garden. This left some nice clean gravel behind.

I'll use the blower at the farm for winnowing gravel. I have gravel which contains lots of leaves and chopped up sticks.

The most obvious conversion for a blower this to turn it into a vacuum cleaner.  This one moves 480 cubic feet per minute, when on turbo.

It works well when separating organic materials from gravel. It could also be used to winnow grains.

I'm planning to use the blower as the cleaning mechanism for deep areas of my rocket mass heater.

I'll place  the blower into the feed hole and seal it tightly,  then give it full power so that all ashes blow to the outdoors.

The blower could be used as a bellows when starting a fire.

I'm putting up a storage building immediately beside the cottage. Rather than give it its own heating,  I'm going to blow heat from the cottage into it occasionally to dry things out.

It gets quite cold sometimes in the winter here. I may use the blower to move air through a similar pipe for preheating the interior of the van. I would plan for this the night before,  by setting up the pipe and opening one of the rear windows a little bit. I'm able to park within five feet of the building. There could be an issue with condensation,  if the air inside the cottage moist.  Many of my trips are very short. I don't want to have to take any time warming up a vehicle for short excursions.

The blower has been working great. I have reduced outdoor sweeping by 90%. It's very easy to make adjustments.

I have used it to clean the interior of several vehicles.

It has been used on about 20 roofs. When loose debris is blown away, shoes grip better and jobs are done more safely. It really speeds up gutter cleaning.

When I'm done working on house moving projects, I blow out the interior of each house. This is much faster than using a vaccum cleaner.

When the garage in the photo was cut from the main house, loose fiberglass insulation could have been blown all over the beach in the strong winds. The blower was employed to move loose material back about 6 feet from the cut.

All of my cordless electric tools are superior to their gas counterparts in many ways. The blower beats all of them.  It is vastly superior to gas powered models.

 The fine control that it allows when I'm cleaning up hard surfaces is much better than what can be achieved with a gas machine.
........
 One thing that I never do with this machine,  is go out on grass and blow leaves around. It's not suitable for that.

 Almost all of my blowing has been outside on hard surfaces or using it inside houses when I'm doing demolition or other work. I've done many things on roofs too.
.......
 Yesterday, I did a lot of drywall sanding.  Today, I will use the blower to clean dust from the ceilings walls window ledges plugs etc.  Dust will settle on the floor,  where it will be vacuumed up.
.........
 I think the reason that this machine is so superior,  is that gas models are such horrible things. They are loud,  stinky and much harder to control.
..........
 I would never consider going back to rake and broom for the largest properties that I service. Without a blower, I would be wasting my time and my customer's money.

I bought another blower. This 80 volt machine is great for blasting wet crap from roof gutters. The battery fits a matching chainsaw.

The E-go machine has seen a lot of use during demolition projects. When chimneys are taken down, houses get dusty. I always work with the wind. Most houses receive about 10 minutes with the blower before travelling to a new location by barge.

While I was demonstrating the blower to a landscaper this morning, my phone rang. My brother has just finished working on a 1000 sq ft space. He needs it cleaned. It's 2 minutes out of my way. $50 for 45 minutes or less. His cleaning guy works cheap, but could never clean a whole house for $50. I'll start by blowing the ceiling, walls, cupboards etc. After a 10 minute break, to let the dust settle, the floors will be blown on the lowest setting.

I will charge others more than this, if it comes up. It's time to build the blower powered shop vac, based on a giant garbage can on wheels. This same brother, who is in the asbestos business, has been promising to get the right hepa filter for months. No asbestos at this job.
