I had the Philips one but after about a year it’s suction changed to the point where it’s hard for it to pick up cat litter now…
It must be able to deal with a lot of cat hair and litter… and preferably be under 500 euros.
Of course I think a corded one is better for my purposes, and I have mostly hard floors with a few small rugs.
The problem is that every year the quality decreases, so it becomes difficult to know which vacuums will still be good. For example, someone may have purchased the same vacuum 5 years ago and think it’s great but the one sold today might not compare
The only reason for a vacuum to lose suction power is due to being clogged somewhere. Maybe it’s time to change the internal filter. The internal filter is usually behind the bag. Try to either wash it or replace it.
Not even that, but damn near fully disassemble and clean it out. I have some random brand from Costco 10 years ago and clean it out annually, and it still works great.
