Best Value Robotic Vacuums – A Comparative Review

It is a given that at this present time, iRobot Roomba products dominate the US market for robotic vacuums. However, as analyzed earlier, iRobot failed to transform Roomba into a mass market product as their focus was on a broad array of niche products. Over the years, a number of competitive products have mushroomed. The competition is more intense in the international arena with many familiar companies opting not to market their products in the US. Roomba’s dominance and their intimidating patent portfolio may be a contributing reason for this segregation.

Below is a look at Robotic vacuum manufacturers, their offerings, and availability information:

Manufacturer	Thumbnail	Models	Comments
iRobot		An array of Roomba 400, 500, and 600-series models	Please see our review.
Infinuvo		CleanMate QQ-1, QQ-2, and QQ-2L (includes home base), QQ-2 Plus (includes home base & scheduler)	Available through Internet retailers. Priced between $100 and $200. Please see our comparative review with Roomba products.
Neato		Neato XV11	A new product introduced in 2010 with new innovations - travels in straight-path with minimal overlaps using a laser range finder and a mapping algorithm (SLAM - Simultaneous Localization and Range Finder). Priced slightly higher than mid-end Roombas at around $400.
LG		HomeBot LRV5900. RoboKing - V-R4000, VR5901KL, VR5902KL, VR6170LVM, and VR6171LVM.	Features the most powerful motor in the Robotic vacuum world. Also features a Lithium Polymer battery that is superior to Ni-Mh batteries used in the Roomba. Relative expensive with models starting around $550. Their marketing materials say the products easily beat the functionality of the high-end iRobot vacuums.
Evolution Robotics		Evolution Robotics Mint 4200 (for hard floors)	Sweeps and Mops hard floors. Great value for under $200. Large areas can be a problem because the cleaning cloth can get too dirty - it doesn't have memory to know where it left off, if you change it in the middle.
TeleBrands Corporation		RoboMaid/RoboMop	Inexpensive (~$30) product available in US, Europe and Asia. A dust-pad and roll-ball at the bottom along with a rechargeable battery forms the product.
Lentek		Intelli-vac	A semi-functional robot that was sold in the US through TV marketing for about $40. Discontinued but still available through e-tailers.
P3 International		An array of inexpensive robots priced between $50 and $150	The Ni-Cd battery does not have enough suction power.
iTouchless		Robotic Intelligent Vacuum Cleaner PRO	Functionality similar to Roomba’s low-end line, but the reviews are below par. Pricing starts at around $140.
Vesture		TrackVac	An RC car and vacuum combo! Priced high at $180
Karcher/Siemens		Robocleaner RC3000 Sensor Cruiser	A fully-functional robot with an innovative two-step (on-board smaller receptacle & a half-gallon receptacle in the base station) dust disposal process. Not available in the US. Expensive at over $1000.
Electrolux		Trilobite	Swedish product categorized as the first commercially available autonomous vacuum cleaner. Considered functionally a lot better than the Roomba with ultrasonic & infrared sensors that allow it to avoid bumps & tripping. Expensive at over $1000 – Not sold in the US, but used ones can sometimes be found on eBay.
Yujin Robot		several products under the ICelbo brand	South Korean company yet to penetrate the US market.
Koolatron		Koolvac	Roomba won suit against Koolatron alleging Koolvac is a Roomba knock-off. As a result it is not sold in the US. Outside the US it is sold for about $200.
Hanool Robotics		Ottoro	Another Korean product – not sold in the US.
Robo Maxx		Robo Maxx	German product – not sold in US - Barebones functionality sold for the equivalent of around $60 in Europe.
Samsung		GTO Hauzen, VC-RE7, and VC-B835R	Yet another Korean product in the very high-end of the market. Not available in the US.
Sharper Image		eVac	It featured a powerful motor and conventional suction design. Sold for between $150 and $300 in 2004. Status: Discontinued.
Floorbotics		iVac	An expensive Australian Robot that claimed to have an algorithm that ensured cleaning areas only once. Retailed for above $1500 in 2005. Status: Discontinued.
Zuchetti		Orazio	An Italian combo vacuum (dry), cleaner (wet), polisher product. Expensive and not sold in the US. Multi-purpose Robot that also cleans & polishes all types of floors - Currently marketed only in parts of Europe.

For a best value comparison, we chose manufacturers that are players in the US and then chose one value offering from each manufacturer/series. Below is our comparison spreadsheet:

Summary:

From the comparison-spreadsheet, it is obvious that the Roomba Red followed closely by the Infinuvo QQ-2 holds a slight edge over the rest of the competition because of better battery and a few other unique and innovative features. That said, P3 International and iTouchless are carving a niche in the deep-value line. The newer versions of these products should give the Roomba Red and Infinuvo QQ-2 a run for their money.

The Vesture TrackVac is unique in its race-car design (the design is patented). But, attempting dual role simultaneously is also its downfall – lack of functionality prevents it from lending credibility to either of its intended purpose – as a vacuum, it lacks power and an absent key feature is the ability to avoid falling down the stairs – as a race car, it is overly bulky for indoor use.

For the value oriented consumer, the suddenly crowded playing field, presents a pick and choose opportunity. iRobot sells the Roomba 400 in the deep-value playing field priced in the $100 range. It is a great value.

Having owned the Roomba 535 for a couple of years, based on our frugal inclinations we have come to realize its excess:

1. The lighthouse and virtual wall technology – we tend to use it a room at a time and the door amply serves to keep the Roomba in. Even in an open floor-plan family area, it is easier to block access to certain areas than reaching for the lighthouse.
2. The self-docking capability – Roomba is usually transported to the desired location sans the dock and returned to the dock for charging.
3. The scheduling interface and the voice demos - The remote for the scheduling option is beyond the scope of our purpose and the voice demo was used only the first time and its real value is moot.

In essence, a bare bones value product at a lower price point would suffice for the likes of us. Even though we salute the convenience of our Roomba, it has to be admitted that the bells and whistles don’t add up to significant value. In our opinion, a lean and mean product in the $100 price range would command a better mass-market appeal than a feature-rich product costing several hundreds.

Having had the experience of owing a Robotic vacuum for over two years, our feeling is that cost of ownership is somewhat higher than traditional vacuums, as the batteries need to be replaced periodically at a sizable cost - we used it once a week or so on the average for around two years when the battery ran out.
