Smart cleaning sounds like one category, but it's actually a handful of different chores. Do you want to keep water from soaking into car upholstery? Do you need a machine to wipe glass for you? Is toilet splash the thing that drives you crazy? Or do you simply need replacements for the carpet cleaner you already own? These four products span from $38.66 to $119.89, and each one is built for a different surface.

Gtechniq I1 Smart Fabric Protection for Cars - Water Repellent 1L
If car seats, door cards, or other interior fabric are constantly absorbing spills, this is the most specialized product in the group. The 1-liter bottle is designed as a water-repellent treatment for automotive fabrics, so you apply it to help moisture bead up instead of soaking in. The Gtechniq I1 comes as an all-purpose treatment in a compact 3.3 x 11.2 x 3.3-inch bottle that stores easily. The limitation is that it protects fabric; it doesn't scrub, wipe, or clean the way the window robot or carpet accessories do.
Window Cleaning Robot, Smart Window Cleaner with Automatic Water Spray Remotes
This one takes over the chore that most people avoid: cleaning glass. The robot uses 2800Pa suction to stay attached while its automatic water spray wets the surface, and the included remote lets you switch cleaning routes without reaching for the device. Its 2.68-inch thin profile helps it creep into tight window spaces, and the 18ft power extension cable gives you plenty of reach before you need another outlet. The white, corded unit is aimed at making window cleaning more hands-off, but the cord does matter: you'll be limited by outlet placement. It only earns its place if windows are a recurring headache.
HOROW Foam Shield Smart Toilet Special Foam Agent
The HOROW foam agent takes a different route: instead of a machine, it adds a protective foam layer inside the toilet bowl. The pack contains two 480ml bottles of foam that are meant to resist splash, isolate odor, and create an anti-stick coating on the bowl so residue has a harder time building up. That makes it a low-effort way to keep a bathroom fresher between deeper cleanings. The limitation is reach: this product is solely for toilet care. It won't help with windows, car fabric, or carpet stains. It also works as a treatment, so plan to use it as part of regular bathroom maintenance.
Hoover Smart Wash+carpet Cleaner REPLACEMENT ACCESSORIES
This is the one to consider only if you already own a compatible Hoover machine. The replacement accessories are designed for the Hoover Smart Wash model and are compatible with the Hoover Smartwash Automatic Carpet Cleaner FH52000. You're getting a washable filter and spot-cleaning accessories in black, with a corded 120V setup. The practical catch is condition: it's listed as open box rather than new. The bigger catch is compatibility: as a replacement accessories set, it has no value on its own. For Hoover SmartWash owners, it's a practical way to extend the cleaner's usefulness.
Final recommendation by use case
Match the product to the surface you're actually fighting. If water stains on car fabric are the annoyance, go with the Gtechniq I1. If windows are the pain point, the window robot with remote control is the right match. If toilet splash and odor are the daily issue, the HOROW foam agent gives you an easy two-bottle barrier. And if a Hoover SmartWash already lives in your closet, the replacement accessories are a sensible way to keep it useful.
