Ignore the leaves, they will be someone else's problem tomorrow. I have an issue with leaf blowers, they simply re distribute the leaves. If they really must be cleaned up, use a spring rake or a lawnmower with a grass collector. Then they can easily be put in the green bin or compost.
I had one ! Gave it away as it was simply quicker to use a broom and bag the leaves ! These blow as many away as they collect making it a job chasing after the leaves.
Use a lawn mower ( cordless if preferred) - it acts like a vacuum and saves having to sweep up the leaves and they can be bagged in one go. BTW leaf mold is a very good mulching medium for supressing weeds.
Rake and lawnmower but if you really insist on getting one then the SGS Engineering petrol model. Batteries aren’t good enough for decent power for blowers etc yet. Might as well use a hair-dryer.
Go for a Stihl petrol combined blower and vac. I use the blower to get the leaves out from under plants and difficult places and then use the vac/shredder. That then goes into a holding pen to strat rotting down than added to compost.
Not for lawns, was thinking gutters and paths, compact in size is a consideration, not looking to blow anything into orbit.
FOr that amount, maybe have a look at teh battery powered Mountfield https://www.mountfieldlawnmowers.co.uk/garden-powered-tools/blowers/cordless-blowers.html there is a cheap one with battery included or the MBL50 that requires a battery too. A friend has one, and does say it is fine for small area but not for whole gardens
I have the stihl petrol with blower and vac. Just use it for vacuuming up as its a nuisance to swop over the pipe to switch between the 2 modes and use a makita 4 stroke for blowing leaves etc... quiet machine and really works well
I have a 2-stroke Stihl blower/vacuum which is really good. I don't find it too troublesome to switch between mode of operation especially if you can plan your work to avoid unnecessary swapping - easier said than done sometimes. Bag emptying is easy. I paid extra for the improved anti vibration model and am glad I did. I still use an older version regularly (without the AV) and you definitely know you've been using that after a while. I also have the Milwaukee compact 18v blower - the one that looks like a 1970s hairdryer on steroids. All the major brands have something similar I think - DeWalt, Makita etc. I have spare batteries so charge time is not an issue. I use that predominantly for quick tidy up jobs if I don't have the Stihl to hand or where I need something lighter and quieter. It's great for shifting water out of mouldings and housings when washing/drying the car/van for instance or blowing leaves/debris to where the mower can pick them up easily. I've used both petrol and battery devices in conjunction a couple of times - the Stihl as a vacuum and the Milwaukee blowing leaves into it that you cannot reach with the suction tube. That worked very well. The two machines probably get equal use most weeks and if either of them got lost/broken/stolen I would replace them without hesitation.
