Performance

Hoover CleanSlate Pet Plus is a mind-blowing addition to the league of portable carpet cleaners. The throttling 3.5 amps (~420 Watts motor) and a plethora of cleaning tools with different types of inserts aid in removing every type of spot stain from any kind of surface. It’s a little noisy (a common trait amongst all carpet cleaners, both portable and full-sized), but you’ll make peace with it after using it for a while.

Hoover Spotless eats up all the residues from your carpet with its powerful 3.5 amps (~420 Watts motor) and strong suction. Surprisingly, it comes with only an antimicrobial rubber nub tool while CleanSlate comes with a set of 4 cleaning tools. However, the nub tool is an all-purpose tool that works flawlessly on all types of carpets and rugs, especially long-pile carpets.

BISSELL Little Green is a cute little carpet cleaner that has a beast-like performance. It munches at all the spot stains and dirt on your carpet like a professional cleaner. With its robust 3 amps (~360 Watts motor), iconic 3-inch tough stain tool, and powerful suction, it cleans your rugs and carpets in no time and threads all the dirt and filth out.

My Verdict: Hoover CleanSlate Pet Plus wins for its powerful suction and a wide range of cleaning tools for every type of stain and surface.

Ease of Use

Using Hoover CleanSlate Pet Plus is as easy as using another spot carpet cleaner. Fill the clean water tank (48 ounces), splash in a spoonful of the solution, plug in the cord (18 feet), release the hose (4.5 feet), attach a tool and that’s it; now start spraying, scrubbing, and let the machine suck up and drop all the filth in the dirty water tank (23 ounces). The same procedure applies to Hoover Spotless and BISSELL Little Green. Note that the DWT fills up quite faster than expected. Hence, you’ll need to empty it twice (maybe thrice) if cleaning multiple stains or surfaces.

Hoover Spotless is also a no-nonsense appliance. Everything’s the same, except the hose (5 feet) and the cord (14 feet), and a few missing tools. Tank capacities are decent, at least larger than what’s available in CleanSlate. Much to users’ ease, its center of gravity is made quite lower to the ground level which makes its maneuverability a lot easier. It renders the unit utmost stability, too.

BISSELL Little Green is a sibling of Spotless in terms of ease of use. A lot of similarities exist except the design and build. Little Green has a 15-feet cord and a 4-feet hose. Tank capacities are also decent enough. However, dirty water tanks’ limited capacity can be a concern as emptying and rinsing them, again and again, is not convenient.

My Verdict: It’s a tie between Hoover Spotless and BISSELL Little Green as you don’t have to fiddle with different kinds of tools and attachments.

Ease of Maintenance

Hoover CleanSlate Pet Plus comes almost in fully-assembled packaging. Just pull it out, fill the tank, attach tools, and start the job. The hose rinse tool flushes accumulated filth out of the hose and the passage, directly into the dirty water tank. You can clean the DWT simply by emptying and rinsing it with clean water (scrub if required). It’s also advisable to fill CWT with just water and empty the tank by spraying water in the sink. It keeps the sprayer intact and unclogged (applies to all three appliances here). Hoover offers a 2-year warranty on the CleanSlate.

Hoover Spotless’s maintenance is also easy due to its self-cleaning feature which allows you to flush its hose after every cleaning session so that dirt and other residues don’t accumulate in and bacteria can be prevented from residing inside the hose. The antimicrobial nub tool also resists microbial build-up. Hoover offers a 2-year warranty on the appliance.

For BISSELL Little Green’s assembly, you neither require any tool nor much time. Right after a minute of unboxing it, you will be all set to use it on your carpet. Emptying and filling up its clean and dirty water tank is quite easy. The HydroRinse self-cleaning hose tool wipes out dirt and debris from inside the hose. It comes with a 1-year warranty.

My Verdict: Hoover CleanSlate Pet Plus and Spotless win for their 2-year warranty in comparison to Little Green’s 1-year warranty.

Portability

Hoover CleanSlate Pet Plus is a compact (low height) and lightweight (only 9 lbs) portable carpet shampooer suitable for carrying around in your home, office, or shop. A sturdy handle on the top ensures a firm grip, making it easier to move around, whether upstairs, downstairs, or across the floor. The cuboid-shape design facilitates ease of storage as it occupies minimum volume and surface area.

Hoover Spotless’s lightweight design (9 lbs) makes it easy to carry it around the house without asking for somebody’s help. You may choose to keep it in your car trunk to take it to your office or shop to do the carpet and rugs there. The sleek and slender built makes it more portable, storable, and compact. You don’t have to spare a spacious place in your store for this. Besides, its ergonomic handle rightly placed at the top of the unit makes commuting with it a breeze.

BISSELL Little Green is one of the most portable carpet cleaners with its bare 9.65 lbs. It can be carried up and downstairs just like a briefcase because of its lightweight and compact build. This reason alone accounts for its wide popularity among consumers. For its portability and small size, it can be cornered anywhere in your attic leaving enough room for other appliances in your tool shed.

My Verdict: All three fair well in this segment.

Versatility

The reason for providing a variety of tools with Hoover CleanSlate Pet Plus is: fight EVERY type of spot stain (fresh or old, pet or food) found on ANY type of surface (carpets, rugs, upholstery, stairs, pet beds, sofa, etc). You get a dedicated pet tool for pet messes (don’t forget to vacuum before using a carpet cleaner), a 4-inch small area tool, a 7-inch WidePath tool, and a tight spot tool for crevices.

Hoover Spotless is also an all-purpose portable carpet cleaner. However, since you get only a basic rubber nub tool, it’s hard to use it for cleaning crevices. But it functions seamlessly on flat surfaces, like carpets, rugs, sofas, pet beds, and stairs. The rub nub is most suitable for pet messes and long-pile carpets.

BISSELL Little Green’s 3-inch tough stain tool makes it easy to access the nooks and crannies of your room. It also performs well on car interior, rugs, upholstery, stairs, and rugs. You can expect this guy to clean a wide range of stains – ranging from vomit, poop to beverage spills. The all-rounder tool works flawlessly but you can consider investing in special-purpose tools for better results.

My Verdict: Hoover CleanSlate Pet Plus wins with a huge margin.

Customer Reviews

Customers are in all awe of the Hoover CleanSlate Pet Plus for its versatile & powerful performance, stunning design, robust build, and affordable price tag. Some highlighted drawbacks comprise insufficient dirty water tank capacity and a weak sprayer.

Hoover Spotless is favored for its stellar performance, compact design, sufficient tank capacities, reasonable price, and self-cleaning technology. Although not a drawback, customers do complain about a shorter cord and a lack of attachments.

BISSELL Little Green is lauded by many consumers for its portability, efficiency, effectiveness, and powerful suction. Low dirty water tank capacity and shorter hose and cord are also some factors voiced by users.

My Verdict: It’s a tie.
