The Roomba 105 Combo with AutoEmpty dock leads the iRobot Roomba Prime Big Deal Days deals for 2026 thanks to its 75-day self-emptying dock, 70X power-lifting suction, and LiDAR mapping at a price most shoppers can justify. For a pure vacuum without the mop, the Roomba 105 Vac is the budget pick worth watching, while the Roomba 105 Combo is a strong middle ground if you want a mop but can skip the self-emptying dock. Prime Big Deal Days runs October 6-7, 2026, and most offers require a Prime membership, so it pays to compare the lineup before the event starts.
Eight current iRobot models are worth tracking this week. We focused on Roomba-only picks (not Shark or Roborock), matched each to a real use case, and highlighted which are the strongest candidates for the sale.

We compared specs, owner ratings, and review counts across the current iRobot lineup, checking each model against the official product listing in October 2026. Self-emptying dock capacity, mopping system type, suction power, and pet hair feedback were the main filters, with review volume used as a tiebreaker for confidence in long-term reliability.
Suction: 70X
Mop: SmartScrub
Dock: 75-day auto-empty
Navigation: LiDAR
This is the Roomba to watch if you want one robot to vacuum and mop and then mostly forget about it for two and a half months at a time. The AutoEmpty dock pulls dust into a sealed bag, and owners report the change interval matches the 75-day claim in most homes. LiDAR mapping is the same generation that ships in the higher 700-series, so coverage feels deliberate rather than random.
Households that want vacuuming, mopping, and self-emptying in a single dock without stepping up to the heated-mop premium tier will get the most from this pick. The 100-minute battery covers a typical floor plan on one charge, and the edge-sweeping brush gets the corners most discs miss.
Several reviews mention the app is more capable than older Roomba apps once it is set up, and that the 2.4GHz WiFi requirement is the only real setup snag. If you have a mesh network, double-check the 2.4GHz band is enabled before you start. The AutoEmpty dock is the meaningful upgrade over the standard Roomba 105 Combo below; the vacuum and mop performance is the same.
The dock is taller than a basic charge base, so plan a spot with about 18 inches of clearance above and a few inches on each side. Skip it if you mainly want a no-frills vacuum; the Roomba 105 Vac below is the cheaper door into the lineup.
Suction: 70X
Mop: none
Dock: self-charge
Navigation: LiDAR
This is the bare-bones pick for someone who just wants a robot that cleans hard floors and carpet without a mop tank to manage. The 200-minute battery is the longest in this lineup, and LiDAR mapping shows up here too, so the cleaning pattern is the neat-row style instead of the older bump-and-go approach. Owners running it on mixed flooring say the multi-surface brush handles transitions without scraping.
Apartments, small homes, and anyone who would rather mop by hand but still wants daily vacuuming will get the most from this pick. The recharge-and-resume feature means the bot will top up and keep going until the whole map is covered, which is unusual at this price point.
The trade-off versus the Combo above is the absence of mopping and a self-emptying dock. The 105 Vac returns to its base to charge and that is the extent of its self-maintenance, so plan to empty the bin roughly every couple of runs in a home with shedding pets. Compared with the 105 Combo at position three, you give up mopping and the smart-scrubbing feature for a noticeably lower entry price during the sale.
It uses the same Roomba Home App as the rest of the lineup, so scheduling, no-go zones, and voice control through Alexa, Siri, or Google Assistant all work without a separate setup. For shoppers who want a low-fuss daily vacuum, this is the cleanest value in the eight picks.
Suction: 70X
Mop: SmartScrub
Dock: self-charge
Navigation: LiDAR
The 105 Combo splits the difference between the budget Vac and the AutoEmpty version: same 70X suction, same SmartScrub mop, but it skips the self-emptying dock. Owners who do not mind emptying the bin themselves save a meaningful amount over the AutoEmpty model, and the mop performance is essentially identical. The 4-stage cleaning system sweeps, lifts, mops, and finishes in one pass when set to combo mode.
Small to medium homes with mixed flooring where someone is happy to empty a bin and refill a water tank every few runs will find this is the right tier. The automatic rug protection means you can run a combo clean without babysitting the robot near area rugs.
You trade the 75-day dock for the lower entry price compared with the AutoEmpty version at position one. Versus the Vac-only model at position two, the addition of the microfiber mop pad and SmartScrub is what you pay extra for, and reviews note it cleans dried spills better than older 600-series Roombas. App complexity is the most common complaint in reviews, so set aside a half hour for the first mapping run.
It needs the same 2.4GHz WiFi as the rest of the lineup, and the mop tank is small, so for very large floor plans you will refill it mid-run. For a two-bedroom apartment or a townhouse, this is the easiest value pick in the lineup.
Suction: 70X
Mop: SmartScrub
Dock: 75-day auto-empty
Navigation: LiDAR
This is the AutoEmpty Combo in a different finish, marketed specifically at pet households. The core is the same as the position-one pick: 75-day bagged dock, SmartScrub mop, and ClearView LiDAR, but the iRobot listing calls out pet and kid use directly. Reviews from dog owners in particular mention the 70X suction is enough to keep up with daily shedding on a single run, and the AllergenLock-style bag keeps dander contained when the dock empties.
Homes with one or more shedding pets where hands-free operation matters more than the difference between 70X and 175X suction will appreciate this configuration. The auto-empty cycle is what most pet owners notice first, because the alternative is emptying a full bin every day.
The headline specs are nearly identical to the position-one 105 Combo + AutoEmpty, and the deciding factor between the two is usually color and current sale price. The trade-off versus the position-three 105 Combo is the dock: you spend more, but the maintenance drops from daily to roughly every two and a half months. If pet hair is the main reason you are buying, the dock pays for itself in time saved.
The dock bag is a consumable, so factor replacements into the long-term cost. The gray finish hides dust on the dock better than the smoke finish on the position-one model, which a few reviews point out as a small plus in pet households.
Suction: 175X
Mop: heated roller
Dock: 75-day empty plus hot wash/dry
Navigation: LiDAR
The 705X is the first Roomba in this list to add heated mopping and a self-cleaning roller mop, so the dock does more than just empty the dust. The 175X suction jump over the 600 series shows up on carpet, and the AI obstacle avoidance is built to spot cords and pet waste before the roller reaches them. Owners with mixed flooring say the extending roller mop gets closer to baseboards than the flat pads on the 100-series.
Shoppers who want premium suction and a true self-cleaning dock, and who do not mind paying for it, should put this on the shortlist. If the sale event trims the price meaningfully, this is the model to watch for buyers who would otherwise look at the 600-dollar-plus tier.
The trade-off is mostly price versus suction compared with the Roomba Max 775 below, with the Max 775 doubling down on raw cleaning power. If you want the dock features but do not need 30000Pa, the 705X is the smarter buy during the sale.
The AutoWash dock is taller and wider than the AutoEmpty dock, so measure your space. The included cleaning solution, dirt bag, filter, and side brush mean you can start using it the day it arrives without ordering accessories.
Suction: 70X
Mop: DualClean spinning
Dock: 75-day empty plus 4-week wash
Navigation: LiDAR
The Plus 405 is built around a 4-week pad-washing dock rather than just a dust dock, which is the feature that matters most in larger homes. The two spinning mop pads scrub more like a manual mop than a dragging pad, and the dock rinses them on a schedule so you are not hand-washing microfiber every few runs. The 120-minute battery covers a large single floor, and ClearView LiDAR maps quickly so you are not waiting around during the first run.
Homes over 2000 square feet where a single charge needs to cover the whole main floor and the mop pads need to stay clean between rooms are the sweet spot. The four suction levels are useful for switching from hardwood to deep carpet without re-mapping.
The Plus 405 upgrades the mop from a single pad to dual spinning pads and adds the pad-wash cycle over the 105 Combo + AutoEmpty at position one, yet the suction spec is the same 70X. The Plus 405 uses a less aggressive mop but is easier to live with in a home with many transitions between carpet and hard floor, because the pads lift where appropriate.
The dock footprint is large, roughly 15 by 20 inches, so check the floor space before you commit. The matte black finish hides dust on the dock better than lighter models, which owners with pets and kids tend to appreciate.
Suction: 30000Pa
Mop: heated roller
Dock: 3-month empty plus heated wash and dry
Navigation: LiDAR
The Max 775 is the strongest vacuum and mop in the current iRobot lineup, and the 4.4-star rating reflects owners who put it through the toughest tests. The 30000Pa suction and heated roller mop at 200 RPM are aimed at homes with heavy pet hair, tracked-in dirt, and dried spills. The dock empties for 3 months between bag swaps and runs a 167F heated wash plus 122F heated dry cycle on the roller mop, so the maintenance is almost zero.
Households with multiple pets, lots of carpet, or allergies where maximum suction and sealed allergen handling justify the price will get the most out of this model. The retracting mop cover is a small but appreciated detail; the mop physically lifts out of the way when the robot transitions onto carpet.
The Max 775 sits at the top of the 7-series stack and adds about 60 percent more raw suction over the 705X, plus a longer 3-month dock window and a heavier overall build. The trade-off is the 39.3-pound weight, which makes the dock harder to move once installed, and the higher price during the sale. If your home does not need 30000Pa, the 705X or Plus 405 will save you a meaningful amount.
The included cleaning solution, dirt bag, filter, and side brush cover the first few months of use, but plan to reorder bags and solution on a regular schedule. The PrecisionVision AI camera is what lets the robot spot pet waste, so make sure the camera lens is wiped clean during monthly maintenance.
Suction: 3X
Mop: lifting spinning
Dock: 90-day empty plus heated wash and dry
Navigation: LiDAR
The Plus 515 is the smallest Roomba in the current lineup at about 3.3 inches tall, which is what makes it the pick for tight homes, low-clearance furniture, and apartments. The 90-day self-emptying dock with a 167F heated wash and 113F heated dry is a step above the basic AutoEmpty, and the lifting spinning mops raise 10 millimeters when crossing carpet to keep rugs dry. The 202-minute battery covers a small space several times over on one charge.
Studio apartments, one-bedroom homes, and anyone whose previous robot could not fit under the bed or couch are the audience for this one. The white finish also suits interiors where a black dock would stand out, which a few reviews mention as a buying factor.
Room size and clearance drive the decision more than anything else with this model: if your furniture has a 4-inch or tighter gap, the 515 is the only Roomba in this lineup that fits. Versus the budget 105 Vac at position two, you trade raw suction for mopping and a real self-emptying dock.
The PerfectEdge technology and tangle-resistant brushes make a noticeable difference in corners and on pet hair, which several owners call out as a reason to choose the 515 over older slim Roombas. Plan a small corner near an outlet for the dock; it is more compact than the Plus 405 dock but still needs clearance on both sides.
Sorting through eight current Roomba models is easier when you match each buying factor to the home it actually serves. The four sections below cover the decisions that change which model is the right pick.
For mostly hard floors and low-pile carpet, the 70X suction in the 100-series is enough, and the 105 Combo + AutoEmpty, 105 Combo, 105X Combo, and Plus 405 all sit in that range. For thick carpet, multiple shedding pets, or allergies, the 705X at 175X and the Max 775 at 30000Pa are the picks with measurable cleaning gains, and owners in those homes tend to rate them accordingly.
Flat microfiber pads with SmartScrub handle everyday kitchen messes and are the simplest to maintain; the 105 Combo, 105 Combo + AutoEmpty, 105X Combo + AutoEmpty, and Plus 515 all use this approach. Spinning DualClean pads and heated roller mops lift the cleaning closer to a manual mop and need either a pad-wash or hot-wash dock; that puts the Plus 405, 705X, and Max 775 in the upper tier. If you mop with a traditional mop and just want daily dust, the 105 Vac is the right fit.
A basic self-charge dock is the lowest tier, found on the 105 Vac and 105 Combo. AutoEmpty docks with 75-day bagged emptying step up to the 105 Combo + AutoEmpty, 105X Combo + AutoEmpty, and the 705X. The Plus 405 adds 4-week pad washing, the Plus 515 adds 90-day emptying with heated wash and dry in a slimmer dock, and the Max 775 tops out at 3-month emptying with the same heated wash and dry. Decide how hands-free you want the experience to be, then pick the matching dock.
Every model in this list uses LiDAR for mapping, so the difference is in the obstacle avoidance system and the dock. The 100-series uses camera-free mapping, the 705X adds PrecisionVision AI for cord and pet waste detection, and the Max 775 layers the same AI plus a retracting mop cover. All eight work with Alexa, Siri, and Google Assistant through the Roomba Home App.
Listings for the same Roomba model can change overnight during the sale, so check the model number in the title (such as Y354020 or X285020) before you buy, and confirm the seller is iRobot or Amazon directly. Bundles that include extra bags, solution, or filters usually cost less per item than buying those separately after the sale. Most offers during Prime Big Deal Days require a Prime membership, and a free trial counts, so it is worth timing the trial if you are not already a member.

Yes. iRobot Roomba models are part of the Prime Big Deal Days lineup every year, and the October 6-7, 2026 event typically includes discounts on the 105 series, 415X, 505X, and 705X. The strongest picks to watch are the 105 Combo with AutoEmpty, the 105 Vac, and the 105 Combo, which are the most common entries in the sale.
The two best times of year to buy a robot vacuum are Amazon’s October Prime Big Deal Days and the late-November Black Friday week. Both events reliably include Roomba models, and the October event is the first major sale before the holiday season. Outside of sale events, prices tend to stay close to MSRP.
For most households, the Roomba 105 Combo with AutoEmpty dock is the best overall pick in 2026 thanks to 70X suction, LiDAR mapping, and a 75-day self-emptying dock. Pet owners with heavy shedding should consider the Roomba Max 775 for its 30000Pa suction and heated roller mop. Shoppers on a budget who just want vacuuming should look at the Roomba 105 Vac.
The Roomba 105 is the current entry-level vacuum and combo line with 70X suction and LiDAR mapping. The 415 series sits in the mid-tier with stronger suction, larger batteries, and additional features like the AutoWash dock on the Plus 405. For most homes, the 105 series offers the best value, while the 415 series is for buyers who want more suction and a more capable dock.
Most Roomba offers during Prime Big Deal Days require an active Amazon Prime membership, but a free 30-day trial counts if you time it to the event. Some deals on the iRobot website do not require Prime but may not match Amazon’s pricing. The October 6-7, 2026 event is the next confirmed date.
Buy the Roomba 105 Combo with AutoEmpty if you want the strongest all-around pick with vacuuming, mopping, and a 75-day dock, and the 49k+ reviews give it the broadest owner track record in the lineup. Buy the Roomba 105 Vac if you want the lowest entry into LiDAR-equipped Roomba cleaning without the mop. Buy the Roomba 105 Combo if you want a mop but do not need self-emptying, and grab the Roomba 105X Combo + AutoEmpty for pet households that want the same core with an allergen-sealed dock. Pick the Roomba 705X or Roomba Max 775 for premium suction and heated mopping, the Roomba Plus 405 for large homes with a pad-wash dock, and the Roomba Plus 515 when clearance under furniture is the deciding factor. Watch prices closely during the October 6-7, 2026 sale window, check the model number on the listing, and use the comparison table above to confirm the features that match your home before you buy.
