Which is better for pet messes on stairs?

The Hoover CleanSlate, because its 7-inch WidePath tool covers stair treads quickly and the TightSpot tool gets into corners. The BISSELL Little Green also handles stairs but with a narrower standard tool.

Which has the bigger tank?

The BISSELL Little Green, at 48 fl oz. The Hoover CleanSlate lists a 1.25 capacity, so you will refill it more often on large jobs.

Is the BISSELL worth the price?

At $74.62 at Walmart as of November 3, 2026, it is the lower-priced option here and has a long ratings record. The Hoover's price is not given, so compare the two live before deciding.

Which is easier to keep clean?

The Hoover CleanSlate, thanks to its self-cleaning hose rinse port. The BISSELL Little Green has no built-in hose rinse, so you clean the hose by hand.

Do both work on upholstery and car interiors?

Yes. Both are portable spot cleaners built for carpet, upholstery, stairs and car seats. The Hoover adds a rubber nub insert for high-pile carpet and pet messes.

There is no reliable lifespan data for either. The BISSELL has a much larger ratings base (29,460), which gives more evidence of how it holds up; the Hoover has little rating history yet.

Hoover CleanSlate Pet Spot Cleaner vs BISSELL Little Green Portable Deep Cleaner

The BISSELL Little Green is the safer buy for most shoppers: it has a large track record (4.4 out of 5 from 29,460 ratings), a 48 fl oz tank and a $74.62 price at Walmart as of November 3, 2026. The Hoover CleanSlate counters with a 7-inch WidePath tool for stairs and large areas, a TightSpot tool for crevices and a self-cleaning hose rinse. Pick the Hoover if wide-area speed and hose cleanup matter more to you than the BISSELL's bigger tank and lower price.
