Purple: The COTIAR R11 is a cordless stick vacuum listed with two detachable batteries and up to 120 minutes of runtime. Its advertised runtime varies by mode, while the listed motor and suction claims should be treated as manufacturer specifications rather than independently verified performance.

Pros and cons

Pros

Two detachable batteries and separate charging are described as allowing battery swaps during longer cleaning sessions.
The green floor-head light and lay-flat design are useful for spotting dust and reaching beneath furniture, according to the listing.
A listed 1.2-liter capacity and all-floor recommendation support routine indoor cleaning.

Cons

The stated 120-minute total is not a single-mode runtime. The described figures fall to 60 minutes in Sport and 30 minutes in Turbo.

What to know before buying

Listing details to confirm

Runtime claims vary by mode. The title and feature copy claim two batteries and up to 120 minutes, while the details field lists 2 hours without a mode; the charging claim of 4 hours also differs from customer feedback mentioning about 2.5 hours. The title advertises 500W and 40KPa, while customer feedback describes 550W suction. The details field's maximum-suction value is listed as “35 picometer,” which does not align with the title's 40KPa claim. The advertised three brush heads and three replaceable filters are not reflected in the explicit included-components field, which lists only a dusting brush. Confirm the selected listing's configuration and mode-specific runtime before purchase.

Customer feedback describes effective pickup, including cat litter from carpet crevices, and positive impressions of suction, handling, weight and battery life. This is relevant to the listing's cordless stick form and advertised floor-cleaning features, but the reported 550W suction differs from the 500W title claim. Feedback also mentions about 2.5 hours to recharge, compared with the 4-hour details listing. Ratings lean positive overall, though a smaller share are low ratings, and aggregate scores do not explain their reasons.

Positive themes

Feedback highlights effective pickup, suction, lighter weight and easy handling.
Battery life is mentioned positively in the supplied customer summary.

Frequently asked questions

How long does the COTIAR R11 run?

The listing claims up to 120 minutes across two batteries, with 60 minutes in Sport and 30 minutes in Turbo. These are manufacturer claims, and the details field separately lists a 2-hour runtime.

What is included with the vacuum?

The explicit included-components field lists a dusting brush. The feature copy also claims three interchangeable brush heads and three replaceable HEPA filters, so confirm which items come with the selected listing.

How long does charging take?

The product details list a 4-hour charge time. Customer feedback mentions about 2.5 hours to recharge, so the actual charging time is not consistent across the supplied information.

What suction does it provide?

The title advertises 40KPa, but a product-details field lists maximum suction as “35 picometer,” and customer feedback refers to 550W suction. Those specifications conflict and should not be treated as settled.
