Litter-Robot 5 and 5 Pro Review: First-Year Cost, What the Pro Adds and Early Owner Reports

What we checked: Whisker's 5 and 5 Pro product pages, the 50-page manual (doc code LR5-8099), and the warranty, returns, and financing pages on 10/09/2026; the App Store listing; 8 owner reviews on Trustpilot and the App Store through 10/09/2026; three written reviews (bgr.com, cats.com, 9to5toys.com); the CPSC recall database on 10/09/2026. Reddit, Chewy, and Amazon did not load for our tools, and we did not reach the checkout.

Whisker launched the 5 line on 10/21/2025. Against the 4, the vendor pages and manual list a full-color LCD with physical buttons (manual, p. 20–22) instead of lights; "3-30 lb cat weight range" instead of 3–25 lb; "up to 5 cats" instead of four; a 10-day one-cat drawer claim instead of 8; WasteID, which the press release says tells feces from urine on each visit; and a gas sensor named in the use-and-care article. The Pro adds "an integrated dual camera system for advanced cat identification" with a 160° diagonal interior view (manual, p. 8), the $29 PetTag RFID collar, and 5 GHz Wi-Fi (p. 44). Unit weight rises from 24 lb to 28.7 lb (Pro 29.6 lb), and the three-year WhiskerCare plan is $149 instead of $129. The 4 itself is covered in our Litter-Robot 4 review.

Whisker claims 10 days per drawer for one cat and prints no decibel figure; the independent reports cover the drawer and the sensors, not the noise.

The manual's own FAQ (p. 43) still says "once per week for a single cat." On noise, the page says "QuietSift® technology that minimizes noise," 9to5toys says "more quietly and smoothly" without a number, and cats.com (03/15/2026; units sent by Whisker) measured nothing; we found no independent dB reading for the 5 as of 10/14/2026.

The Litter-Robot 5 shows "As low as $799" and the 5 Pro "As low as $899" at litter-robot.com on 10/09/2026 and again on 10/14/2026, with no struck-through list price and no sale; the fence, one carbon filter, and five liners are in the box. Bundles run from $948 (Warranty) to $1,771 (Double, two units) on both dates. PetSmart listed the 5 at $799 and the Pro at $899.99 on 10/09/2026.

Shipping is "Free shipping (ex. AK/HI/PR)." Sales tax varies by state and is added at checkout, which we did not reach; Whisker's FAQ has no sales-tax entry (10/14/2026). No subscription is required; Whisker+ is optional at $7.99/month after a 30-day trial or $79.90/year (litter-robot.com/whisker-plus, 10/14/2026).

About $909 for the Litter-Robot 5 and about $1,009 for the 5 Pro before sales tax, from Whisker's prices and intervals:

• Litter-Robot 5: $799, or 5 Pro: $899 (litter-robot.com, 10/14/2026); shipping $0 to the contiguous US; required subscription $0
• Waste drawer liners: $25 for 25, $1 each; "once every 10 days" for one cat (manual, p. 17) is about 37 liners, about $37
• Carbon filters: $12 for 2, $6 each; "approximately 1 month" each (manual, p. 35), about 12 filters, about $73
• First year, before tax: about $909 (5) or about $1,009 (5 Pro), plus sales tax — varies by state

Not in that total: OdorTrap packs, $15 per 3-pack, "every 2-4 weeks" (manual, p. 36); Whisker+ at $79.90/year; the $29 PetTag for the Pro; litter, which is your choice, with a fill of about 1 gallon (4 L) (p. 13). Any 10–13 gallon bag works in place of the liners (p. 17); two cats empty every 5 days per the use-and-care article, which doubles the liner line.

On 10/09/2026 the 5 line was at Whisker's own store and PetSmart at the same prices: $799 for the 5 and $899 or $899.99 for the Pro, with 2 and 12 PetSmart reviews and no star average shown. Chewy's search returned HTTP 429 to our tools on 10/09/2026 and 10/14/2026, with no Litter-Robot 5 in its snippets, and Whisker has no official Amazon listing. No seller requires a subscription. The difference is paperwork: units from Whisker's stores get the 90-day in-home trial and automatic registration, while robots bought elsewhere need manual activation and the extended plan "Does not apply to robots sold by anyone other than Whisker or Whisker-approved distributors."

Not checked at checkout as of 10/09/2026. The product pages show only "Buy now, pay over time," with no monthly figure. Whisker's financing page says "Your rate will be 0%–36% APR based on credit" over "3, 6, 12, or 18 months" through Affirm.

One year of WhiskerCare is included; the three-year plan is $149 for both the 5 and the 5 Pro, $20 more than for the 4. The legal page lists accidental damage, defects, power surges, mechanical and electrical breakdowns, and software support; exclusions are modifications, non-Whisker parts or third-party service, pet-caused property damage, and a "$75 cleaning fee" for units returned unclean. Returns within the 90-day in-home trial cost your own shipping or a $60 prepaid label deducted from the refund, need an RMA, and post "within 7-10 business days" after receipt (the FAQ on the same page says 10–30 days). A Trustpilot reviewer (09/25/2026) says a Costco unit "comes with a year warranty" that cannot be extended.

The 5 line uses the same consumables as the 4 at the same printed prices (10/09/2026): Waste Drawer Liners $25 for 25, now drawstring; Carbon Filters $12 for 2, "Compatible with Litter-Robot 4, Litter-Robot 5/Pro, Litter-Robot EVO"; OdorTrap Packs $15 for 3, with a $30 holder that "snaps right into the Litter-Robot 5 filter cover" (manual, p. 36); PetTag $29, Pro only. The LCD prompts "Replace filter soon" and "New filter required." Accessories are on the Litter-Robot accessories page.

Support is the same Auburn Hills, Michigan desk: phone 1-877-250-7729, chat, and tickets. Whisker's error-code article for the 5 lists "Extended scale activity: The scale detected activity for over 30 minutes," among others. As a seller, Whisker holds 3.3/5 on Trustpilot over 609 reviews and an A+ with the BBB, with 89 complaints in three years (both 10/09/2026).

The 5 adds sensors to the 4's two-way detection, and the minimum weight is printed two ways. Whisker says the unit uses "multiple lasers and weight sensor technology" to detect entries and exits. Manual, p. 23: "If additional weight is detected during a cycle, the Globe will stop. After 15 seconds of the additional weight exiting, the Globe rotation will resume. The weight sensors are also used to weigh waste after each visit." Page 48 prints "CLASS 1 LASER PRODUCT," IEC 60825-1:2014, and EN 50689:2021.

The product page says "3-30 lb cat weight range." The manual says cats "must weigh 2 pounds or more" (p. 3), "Kittens must weigh at least 2lb" (p. 33), and "between 2 and 30 pounds" (p. 42); the manual's 2 lb is below the 3 lb (1.36 kg) the Litter-Robot 4 manual prints. The one independent report, bgr.com (02/08/2026), is about detection failing: "extended scale activity" with nothing in the globe, the same error that leads Whisker's own error-code list.

The manual's drawing prints the drawer at 5.50 x 13.50 x 19.00 in (p. 8), with no volume in liters. Liners are drawstring now, and "white bags work best" (p. 17, p. 35). Odor control is the monthly carbon filter in the drawer cover plus the optional OdorTrap holder; none of the 8 owner reviews we read mentioned odor, and there is no independent odor measurement.

Clumping litter only. Manual, p. 13: "We recommend a high-quality, clay-clumping litter, such as GreatLitter®. Litter beads and crystals that are small enough to pass through the screen will also work"; non-clumping and newspaper-based litters are ruled out, and translucent or white litter "may impact the LitterLevel® and Drawer Full" (p. 3). Footprint is 22.00 x 27.25 x 29.50 in in the manual (p. 8), 29.9 in tall on the product page; the entryway is 15.75 x 15.75 in. A rechargeable 12 V backup battery is an option (p. 34).

Whisker's FAQ says "The Whisker app is not required for Litter-Robot to function" without naming a model (litter-robot.com/faq.html, 10/14/2026); the 5's "offline" support article says only that "remote commands will not function," and the 5 has an LCD with "real-time updates and notifications" and physical buttons (manual, p. 20–22). The 5 is "2.4 GHz only (5 GHz band not supported)"; the Pro "can be used on either 5ghz or 2.4ghz WiFi networks" (p. 44).

Free in the app: "SmartScale identification and weight tracking," WasteID, and for the Pro "real-time video streaming (5 minutes daily)" with "the last 2 days of videos and events" in the cloud. Whisker+ adds unlimited streaming, AI facial-recognition cat ID, two years of history, and Patterns (beta). On the App Store (10/09/2026) the app holds 4.8 of 5 over 148K ratings; on Google Play (10/14/2026) it is rated 4.7 over about 60,000 reviews, and the Data safety section says "No data shared with third parties" and lists Personal info, Photos and videos, and App activity as data the app may collect. The App Store privacy label, verbatim. Data Linked to You: Advertising or Marketing, Contact Info (Email Address, Name); Analytics, Identifiers (User ID, Device ID); App Functionality, Contact Info (Email Address, Name), User Content (Photos or Videos), Identifiers (User ID, Device ID), Usage Data (Product Interaction). Data Used to Track You: Contact Info, Identifiers. On the Pro, "Photos or Videos" includes the camera footage.

No recall found as of 10/14/2026: the saferproducts.gov recall API returned nothing for "Whisker," "Litter-Robot," or "litter box" that day. On 10/09/2026 we searched cpsc.gov/Recalls for the same terms; none of the listings related to this product.

Not enough owner reviews read yet (8 read on Trustpilot and the App Store), so we publish no Owner Complaint Index; the 5 line has been on sale for under a year. We don't count Whisker's own page (4.6/5 over 254 reviews for the 5, printed as 4.7 in the reviews section; 4.5/5 over 312 for the Pro); r/litterrobot and Chewy did not load for our tools.

What owners complain about

Themes across the 8 reviews: sensor errors 3, app or Wi-Fi 2, motor or mechanical 2, customer support 2. "Customer service determined that we need a replacement power supply" (Trustpilot, 10/02/2026, a 5 that failed within a month; the part "could take a week"). An App Store review titled "None of the Advertised Features Work (Litter Robot 5 Pro)" (08/20/2026) says cat detection and weight recording fail while a subscription is still charged (paraphrase, not verbatim).

What owners praise

Replacement parts shipped promptly: "She ordered the parts I needed and told me when to expect them" (Trustpilot, 09/19/2026, a sensor problem). Reviewers rather than owners supply the other praise: the quieter cycle (9to5toys, no number) and WasteID insights (cats.com).

Pros:

• 3–30 lb rated range and "up to 5 cats" on the product page, against 3–25 lb and four on the Litter-Robot 4
• LCD and buttons on the unit (manual, p. 20–22), so error codes read without the app
• Same $1 liners and $6 filters as the 4; no required subscription

Cons:

• $100–$200 more than the Litter-Robot 4; about $909 or $1,009 in the first year
• The only independent Pro report logged sensor errors and weekly resets (bgr.com, 02/08/2026)
• Minimum weight printed as 3 lb (page) and 2 lb (manual, p. 3, p. 33, p. 42)
