Carpet/Car Cleaning Advice

First of all, I’m not sure if this is the right community (other than it’s something I’ll be doing myself). So if anyone knows a better community to ask this, I’ll be happy to take my post over there.

Alright, I am looking to buy a portable/handheld carpet/upholstery wet/dry vacuum cleaner so I can detail my truck, clean up stains in my carpet/furniture, etc.

I was eyeing the Hoover CleanSlate Plus, but wanted to see what other units that might be better and/or more affordable? If it matters, my budget would be as close to $100 as practical, but there may be wiggle room for the right unit.

Thanks!
