I can comment on this as I just bought one a couple weeks ago to retire a tired old unit.
I ended up with a Powerplay Spyder from CDN Tire.
First things first: I wanted compact when not in use. I store mine in the garage so a small footprint was one of the main "wants". And this delivers. It is without a doubt very compact when not in use, taking up barely more room than a couple jugs of washer fluid. See photo. It's also light. IQ can easily pick it up and carry it around one hand. It's less than 20 pounds I'd say. Set up is a breeze: screw wand into hand trigger, screw hoses into unit, plug in and go.
Next was stability. Since it's so squat and compact and has 4 wheels on wide outriggers, this thing NEVER tips. And it drags easily across the lawn too. Important for me as I spray my house after the June fly invasion.
It's quiet. At 2000psi it's strong enough for my needs (general cleanup, foam cannon/car washing). See patio brick I sprayed with 25 years of dirt. And again..I can't stress how compact, light yet stable it is.
Now I had a hard time (initially) finding adequate reviews. But then I found it's just a re badged Westinghouse sprayer as sold in the US, so there's plenty of reviews.
All in all, I'm really pleased with this one provided it lasts a good while.
