I have a Greenworks cordless chainsaw. This was my first electric chainsaw and I was skeptical about its performance compared to my trusty Stihl 2-stroke. After a year at Greenworks, I believe in Greenworks. This battery stick from Greenworks is in no way inferior to my Greenworks chainsaw. For example, at $350, Greenworks is putting pressure on offers from Dyson, LG, Tineco, etc. that cost twice as much. I believe this is Greenworks' first cordless vacuum and they got it right. Okay, before I get to the things I like, let me list one downside I found: The drip tray is small compared to my Dyson v10's dirt tank. . That's all. Now for the merits of this Greenworks vacuum cleaner: 1) Power. Straightforward - and most importantly - this cordless vacuum cleaner delivers amazing suction power at maximum power (three power levels) and good suction power at minimum power. In terms of suction power, it is at least as good as my Dyson v10.2) electric floor brush. The powered brush head is wide with relatively small gaps on each side behind the powered roller. The roller pulls out easily for cleaning and detangling - all you have to do is press the small lever on the bottom of the roller to release it. The roller combines rubber brushes with short, soft bristles, a combination that works on carpets and hard floors. 3) tools. There are a lot of good attachments included and they are solidly built unlike the Dyson attachments. The kit includes an additional, narrower electric brush for deep cleaning, a crevice tool and two general purpose dusting nozzles. 4) Trigger. The trigger is excellent. Press once and the vacuum cleaner turns on. Press again and the vacuum cleaner will turn off. No need to hold the trigger while cleaning. 5) emptying. Every Dyson I've had felt like it would break one day because the Dyson's deflation levers were difficult to control. This vacuum cleaner is easy to empty. 6) Ability to get under things. This vacuum cleaner goes well with our sofas. Many vacuums can't do this due to bulky connectors or high-profile floor brushes. Those things aside, this is a lightweight vacuum cleaner. It comes with a wall charger that you can hang the vacuum on. The charger also includes a tool holder. This is a great vacuum cleaner from Greenworks. It's not far behind Shark, Dyson, Tineco & Co., although Greenworks falls into that category for the first time.
